Acute and chronic dietary exposure and risk assessments of chlorpyrifos residues for food 

and for water were conducted using the Dietary Exposure Evaluation Model DEEMFCIDTM, Version 2.03. [The chronic assessment of food residues was done with and 

without FHE included.] The DEEM-FCIDTM program currently uses food consumption 

data from the U.S. Department of Agriculture’s Continuing Surveys of Food Intakes by 

Individuals (CSFII) from 1994-1996 and 1998. These analyses were performed to 

support the registration review of chlorpyrifos. 

Residues in food are assumed to consist of parent chlorpyrifos only, while residues in 

water are assumed to consist of chlorpyrifos oxon only. Therefore food residues are here 

assessed to toxicological points of departure (PODs) based upon the toxicity of the parent

and water residues are assessed to points of departure based upon the toxicity of the oxon. 

These are highly refined dietary exposure analyses. The food residues used were based 

upon U. S. Department of Agriculture’s Pesticide Data Program (PDP) monitoring data 

except where no appropriate PDP data were available. The Biological and Economic 

Analysis Division (BEAD) of OPP provided extensive percent crop treated information. 

Food processing factors from submitted studies, from a submitted non-guideline cooking 

study, and from the public literature were used as appropriate. All residues in the food 

are assumed to be present as parent chlorpyrifos only.

For all of the food assessments a chlorpyrifos based point of departure (POD) of 0.0036 

mg/Kg/day was used for all population subgroups for the acute analyses and a POD of 

0.0003 mg/Kg/day was used for all population subgroups in the chronic analyses. 

Environmental Fate and Effects Division (EFED) has provided estimated drinking water 

concentrations (EDWCs) for chlorpyrifos residues based upon a variety of scenarios. 

Three scenarios were selected by the chlorpyrifos assessment team that it is hoped

effectively represent real conditions: an upper exposure scenario based upon a grape use 

with some label restrictions, a lower bound scenario for sugar beets, and a scenario 

representative of many crops towards the lower middle of the distribution based on 

residues expected for corn and soybeans. The combination of these three scenarios is 

believed to provide good representation of the risk expected in drinking water when 

pesticide runoff from crops is present. 

All residues in drinking water were assumed to be in the form of the oxon because

scientific literature, as well as monitoring data, suggest rapid conversion of chlorpyrifos 

to chlorpyrifos-oxon during drinking water disinfection and also show that the oxon is 

relatively stable after drinking water disinfection.

For all of the water assessments an oxon based point of departure (POD) of 0.0005 

mg/Kg/day was used for all population subgroups for the acute analyses and a POD of 

0.00011 mg/Kg/day was used for all population subgroups in the chronic analyses.

The assessments show that residues in water always exceed the level of concern for acute 

exposures for at least one subpopulation (infants) and water residues generally exceed for 

both acute and chronic exposures for other populations at higher residue scenarios. 

Meanwhile exposures through food do not exceed the level of concern for either acute or 

chronic exposures for any population. 

 

Given the above exposure results, the much greater predominance of water residues over 

food residues, and the quantitative toxicological uncertainties in combining chlorpyrifos

based vs. chlorpyrifos-oxon based toxicities, the food and water exposures have not been 

aggregated in this assessment The two toxicological PODs differ somewhat in 

quantitative meaning and toxicity adjustment factors (TAFs) that have been calculated to 

convert between the parent and the oxon also differ from the ratio between these two 

PODs. Since there is this uncertainty in aggregating the toxicities of parent and oxon,

and no regulatory value to aggregating food and water, no aggregated food and water 

assessments are presented here. Should the need arise such aggregation may be 

considered in a future assessment.

Acute Food and Acute Drinking Water Dietary Exposure Results and Characterization

For food alone, using the chlorpyrifos POD, the exposure for the general U. S. Population 

was 5.0% of the acute population adjusted dose (aPAD), and for the most highly exposed 

population subgroup, children 1-2, was 9.0% aPAD. The aPAD is OPP’s level of 

concern for acute exposure. If an additional 10X uncertainty factor is invoked these 

exposures will be tenfold higher when expressed as a percent of the PAD. Residues in 

peaches, peppers, apples, plums grapefruit juice, grape juice, soy milk, cranberry juice 

and orange juice were generally drivers of acute food exposure. 

For water alone several maximum application rate scenarios were tested. For maximum 

application rates a sugar beet scenario was considered by the team to represent the 

reasonable low end scenario of agricultural water runoff. In this scenario the acute 

exposure for the general U. S, population was 60% aPAD, and for all infants was 210% 

aPAD. For the low – middle corn/soybean scenario selected by the team to be a 

“representative” scenario, the acute exposure for the general U. S, population was 240% 

aPAD, and for all infants was 770% aPAD. For the restricted grape scenario considered 

by the team to represent the reasonable high end the acute exposure for the general U. S, 

population was 810% aPAD, and for all infants was 2,700% aPAD. Again, addition of a 

10X uncertainty factor will result in exposures that are 10X higher when expressed as a 

% aPAD. . 

These water scenarios were also evaluated at average typical application rates. For a 

typical application rate for the sugar beet scenario the acute exposure for the general U. 

S, population was 99% aPAD, and for all infants was 340% aPAD. For the corn 

scenario, for a typical application rate the acute exposure for the general U. S, population 

was 38% aPAD, and for all infants was 120% aPAD. For the restricted grape scenario,

for the acute exposure for the general U. S, population was 19% aPAD, and for all infants 

was 59% aPAD. . . 

Chronic Food and Chronic Drinking Water Dietary Exposure Results and 

Characterization

For food, without food handling establishment uses (FHE) included, the exposure for the 

general U. S. population was 3.0% of the chronic population adjusted dose (cPAD), and 

for the most highly exposed population subgroup, children 1-2, was 8.4% cPAD. The 

cPAD is OPP’s level of concern for chronic exposure. If a 10X uncertainty factor is 

invoked the food results would be tenfold higher when expressed as a percent cPAD. 

For food with FHE uses included, exposure for the general U. S. population was 3.7% 

cPAD, and for the most highly exposed population subgroup, children 1-2, was 11% 

cPAD. If a 10X uncertainty factor is invoked the food results would be tenfold higher 

when expressed as a percent cPAD. Thus chronic exposures from food with FHE uses 

included would exceed the cPAD if an additional 10X uncertainty factor is invoked. 

For water alone the same three scenarios as discussed under acute exposure were tested. 

For the sugar beet scenario considered by the team to represent the reasonable low end 

the chronic exposure for the general U. S, population was 21% cPAD, and for all infants 

was 69% cPAD. For the low – middle corn/soybean scenario selected by the team to be a 

“representative” scenario, the chronic exposure for the general U. S, population was 84% 

cPAD, and for all infants was 280% cPAD. For the restricted grape scenario considered 

by the team to represent the reasonable high end the chronic exposure for the general U. 

S, population was 270% cPAD, and for all infants was 890% cPAD. Again, addition of a 

10X uncertainty factor results in exposures that are 10X higher when expressed as a % 

cPAD. 

The same three scenarios were also tested at average typical application rates. For the 

sugar beet scenario at the typical application rate the chronic exposure for the general U. 

S, population was 82% cPAD, and for all infants was 270% cPAD. For the corn 

scenario, for a typical application rate the chronic exposure for the general U. S, 

population was 15% cPAD, and for all infants was 49% cPAD. For the restricted grape 

scenario, for a typical application rate the chronic exposure for the general U. S, 

population was 7.9% cPAD, and for all infants was 26% cPAD. 

I. Introduction

Dietary risk assessment incorporates both exposure and toxicity of a given pesticide. For 

acute and chronic assessments the risk is expressed as a percentage of a maximum 

acceptable dose (i.e., the dose which HED has concluded will result in no unreasonable 

adverse health effects). This dose is referred to as the population adjusted dose (PAD). 

The PAD is equivalent to point of departure (POD, NOAEL, LOAEL, e.g.) divided by 

the required uncertainty or safety factors.

Page 5 of 128

For acute and non-cancer chronic exposures HED is concerned when estimated dietary 

risk exceeds 100% of the PAD. References which discuss the acute and chronic risk 

assessments in more detail are available on the EPA/pesticides web site: “Available 

Information on Assessing Exposure from Pesticides, A User’s Guide,” 21-JUN-2000, 

web link: http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf ; or see 

SOP 99.6 (20-AUG-1999).

The most recent HED dietary exposure assessments for chlorpyrifos were conducted by 

D. Soderberg (22 Jun 2000, D263890 and D263889). Please note that no new uses have 

for chlorpyrifos have been introduced in the interim. As well as using updated residue 

and usage data, the current assessments differ from the old primarily in having new 

toxicological points of departure, having the new cooking studies available, and in 

following updated policies for calculating dietary exposure. 

II. Residue Information

Sufficient information was available to conduct highly refined assessments; Chlorpyrifos 

is included in virtually all PDP monitoring. For processing factors, in addition to the 

usual sources, a non-guideline cooking study has been submitted (MRID 45619801) and 

there is a considerable public literature on the effects of processing on chlorpyrifos 

residues, albeit those latter results must be approached cautiously. Attachment 1, a table 

followed by explanations of the residue information, describes in detail the input for 

various crops and their commodities as used in this assessment. 

Chlorpyrifos Use:

Chlorpyrifos is an organophosphate insecticide that has numerous uses on a wide variety 

of crops and ornamentals. Chlorpyrifos is also used in livestock ear tags to control flies. 

It has a tolerance for food handling uses and there appear to be two active labels for this 

purpose at this time. There are no new crop uses for chlorpyrifos since the last 

reregistration action. There is a tolerance for lettuce listed in 40 CFR 180.342 but that 

tolerance was not supported by the registrant and has been withdrawn. Important 

mitigations in the last reregistration reduced or removed uses on grapes, apples and 

tomatoes. All present tolerances are considered permanent. 

From PDP (and BEAD) data it appears that chlorpyrifos is either regularly applied 

illegally to a variety of crops or that residues occur on several crops that are rotated in 

after use of chlorpyrifos on a legally registered crop. Data on crops without tolerances 

are not ordinarily included in EPA assessments. Omission of residues on these crops 

may lead to some underestimation of exposure in the current assessment. The extent of 

this problem is shown in Attachment 2, a list of illegal residues found by PDP on crops 

for which chlorpyrifos has no registered use.

The residues of concern for chlorpyrifos in food are for the parent only. Residues of 

concern in drinking water may include both parent and oxon, but because treated drinking 

water is often exposed to strong oxidants as disinfectants, all residues in drinking water 

are assumed to be present as the oxon. 

Residue Data used for Acute and Chronic Assessments:

Residue data are almost entirely based upon PDP data. For crops not tested by PDP 

translations have been made from tested crops. Occasionally, older PDP data has been 

used where it represented the best estimate of real residues. Field trial data or tolerances 

have been used for a very few crops where translations from PDP data were not possible. 

The same data were used for both the acute and chronic assessments.

Most input residues for the acute assessments are incorporated as residue data files 

(RDFs). The acute drinking water input from EFED’s water model distribution is also 

incorporated as an RDF. Except for drinking water, a complete listing of RDFs is

provided in Attachment 5. Because the predicted drinking water residues cover 30 years, 

these water RDFs are too large to be attached. 

BEAD has provided a SLUA (10 March 2010), a list of percent crop treated estimates to 

be used for this assessment, which is included as Attachment 3. An addendum to that 

SLUA elaborates results for some additional crops and an estimated a maximum possible 

percent of FHE establishments treated. This latter is set at the sensitivity of BEAD’s 

ability to determine establishments treated. 

Processing factors were taken primarily from three sources, the recently submitted 

cooking study, MRID 45619801, the two previous dietary exposure assessments, 

D263889 and D263890, and from DESAC policies on default factors. The exception is 

the sugar beet processing study, MRID 0039641. This study had been rejected because 

incurred residues were non-detectable prior to processing. However, fortified samples 

were also taken through processing and it was decided that these fortified sample results 

provide the most realistic estimate of processing factors for residues in sugar beet sugar 

and sugar beet molasses. A short summary of the factors determined in the cooking study 

follows:

III. Drinking Water Data

The drinking water residues used in the dietary risk assessment were provided by the 

EFED in the following memorandum: Revised Chlorpyrifos Preliminary Registration

Review Drinking Water Assessment PC Code 059101 DP Barcode 368388, 389480, 

30 June, 2011, by Rochelle Bohaty, and was incorporated directly into this dietary

assessment. Water residues were incorporated in the DEEM-FCID into the food 

categories “water, direct, all sources” and “water, indirect, all sources.” 

All estimated drinking water concentrations used in this assessment are based upon the 

PRZM-EXAMS model. For the chronic assessment the 1-in-10 year annual means from 

PRZM-EXAMS were used. Residues were estimated according to three scenarios: a low 
Chlorpyrifos Dietary Exposure and Risk Assessment DP Number: D388166

end scenario based upon sugar beet uses, a more central corn/soybean scenario, and a 

high-end scenario restricted grape uses. These water scenarios are based on maximum 

labeled use rates. Residues were also estimated for these three scenarios using average 

typical use rates (Table 2).

The PRIZM-EXAMS model and its description are available at the EPA internet site: 

http://www.epa.gov/oppefed1/models/water/. 

Tier II chlorpyrifos-oxon EDWCs for grapes, corn/soybean and sugar beets are provided 

in Table 2. Grape, corn/soybean and sugar beet were singled out for this preliminary 

drinking water assessment as representative crops because there is a large amount of 

chlorpyrifos applied to these crops per year, a large portion of these crops are treated with 

chlorpyrifos, and/or the use locations are distributed throughout the United States. In 

addition, the reported EDWCs for grapes, corn/soybean and sugar beets are generally 

representative of the other chlorpyrifos use scenarios modeled when EDWCs are 

compared.

There are two modeled chlorpyrifos maximum use scenarios that result in EDWCs that 

are substantially higher than the majority of the modeled chlorpyrifos use scenarios. 

These use scenarios are for grape and turf. The EDWCs reported for Grape HR (high 

rate; 33 lbs a.i./acre) are the result of a high application rate trunk drench/soil application 

which is currently permitted on labels and may not represent actual or intended use of 

chlorpyrifos on grape (and is clearly far above the typical use rate). Some recently 

approved labels restrict the use of chlorpyrifos on grape to 6 lbs a.i./A. The EDWCs 

reported for Turf FA (frequent applications) is based on 26 applications (limit of PRZMEXAMS) and a 3 day application interval. This scenario was developed to highlight the 

uncertainty associated with the unrestricted use of chlorpyrifos on turf (turf labels do not 

currently restrict the number of chlorpyrifos applications per year or the maximum 

number of applications of chlorpyrifos per year) and may not may not represent actual or 

intended use of chlorpyrifos on turf. Results of exposure assessment on the high end

unrestricted grape use are presented as attachments 14 and 18. Turf exposures were not 

calculated but would be slightly lower.

Acute Drinking Water Exposures

For the acute probabilistic assessment the entire distributions from the PRZM-EXAMS 

for the three scenarios were considered: a low end scenario representing residues from 

use on sugar beets, a large low – mid range use on corn and soybeans, and a high end 

restricted application to grapes. Distributions were developed and used for both the 

maximum applications rates and the average typical use rates for each scenario.

The full 30 year distributions that were provided based upon PRZM-EXAMS for the 

purpose of creating RDFs are too large to reproduce here, but these distributions will be 

made available electronically. 

IV. DEEM-FCIDTM Program and Consumption Information

Chlorpyrifos acute and chronic dietary exposure assessments were conducted using the 

Dietary Exposure Evaluation Model software with the Food Commodity Intake Database 

DEEM-FCIDTM, Version 2.03 which incorporates consumption data from USDA’s 

Continuing Surveys of Food Intakes by Individuals (CSFII), 1994-1996 and 1998. The

1994-96, 98 data are based on the reported consumption of more than 20,000 individuals 

over two non-consecutive survey days. Foods “as consumed” (e.g., apple pie) are linked 

to EPA-defined food commodities (e.g. apples, peeled fruit - cooked; fresh or N/S; baked; 

or wheat flour - cooked; fresh or N/S, baked) using publicly available recipe translation 

files developed jointly by USDA/ARS and EPA. For chronic exposure assessment, 

consumption data are averaged for the entire U.S. population and within population 

subgroups, but for acute exposure assessment are retained as individual consumption 

events. Based on analysis of the 1994-96, 98 CSFII consumption data, which took into 

account dietary patterns and survey respondents, HED has concluded that it is most 

appropriate to report risk for the following population subgroups: the general U.S. 

population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-

19, adults 20-49, females 13-49, and adults 50+ years old.

For chronic dietary exposure assessment an estimate of the residue level in each food or 

food-form (e.g., orange or orange juice) on the food commodity residue list is multiplied 

by the average daily consumption estimate for that food/food form to produce a residue 

intake estimate. The resulting residue intake estimate for each food/food form is summed 

with the residue intake estimates for all other food/food forms on the commodity residue 

list to arrive at the total average estimated exposure. Exposure is expressed in mg/kg 

body weight/day and as a percent of the cPAD. This procedure is performed for each 

population subgroup.

For acute exposure assessments individual one-day food consumption data are used on an 

individual-by-individual basis. The reported consumption amounts of each food item can

Page 10 of 128

be multiplied by a residue point estimate and summed to obtain a total daily pesticide 

exposure for a deterministic exposure assessment, or “matched” in multiple random 

pairings with residue values and then summed in a probabilistic assessment. The 

resulting distribution of exposures is expressed as a percentage of the aPAD on both a 

user (i.e., only those who reported eating relevant commodities/food forms) and a percapita (i.e., those who reported eating the relevant commodities as well as those who did 

not) basis. In accordance with HED policy, per capita exposure and risk are reported for 

all tiers of analysis. However, for tiers 1 and 2, any significant differences in user vs. per 

capita exposure and risk are specifically identified and noted in the risk assessment.

have not been aggregated and these TAFs were not included in the assessments as 

adjustment factors.

Acute Food Only and Drinking Water Only Dietary Exposure Results and 

Characterization

The most highly exposed population subgroup for food was children 1-2, at 9.0% aPAD. 

The exposure for the general U.S. population from food was 5.1%. Residues in peaches, 

peppers, apples, plums grapefruit juice, grape juice, soy milk, cranberry juice and orange 

juice were generally drivers of acute food exposure. (Residues on fresh peaches, plums 

and peppers in particular strongly tend to be on the imported crops rather than on 

domestically grown crops.) 

For water alone in the low end sugar beet scenario at the maximum application rate the 

acute exposure for the general U. S, population was 61% of the aPAD based upon the 

chlorpyrifos oxon. [For the typical application rate it was 99% of the aPAD.] For all 

infants, the most highly exposed population subgroup, at the maximum rate the exposure

was 210%. [For the typical application rate it was 340% of the aPAD.] 

For water alone in the low-mid range corn-soybean scenario the acute exposure for the 

general U. S, population at the maximum application rate was 240% of the aPAD based 

upon the chlorpyrifos oxon POD. [For the typical application rate (corn only) it was 38% 

of the aPAD.] For all infants, the most highly exposed population subgroup, at the 

maximum rate the exposure was 770% aPAD. [For the typical application rate it was 

120% of the aPAD.] 

For water alone in the high end restricted grape scenario the acute exposure for the 

general U. S, population at the maximum application rate was 810% of the aPAD based 

upon the chlorpyrifos. [For the typical application rate it was 19% of the aPAD.] 

For all infants, the most highly exposed population subgroup, at the maximum rate the 

exposure was 2,700% aPAD. [For the typical application rate it was 59% of the aPAD.] 

The results of the acute dietary exposure analyses are reported in Tables 6-7.

Chronic Food Only and Drinking Water Only Dietary Exposure Results and 

Characterization

The most highly exposed population subgroup for chronic food only were children 1-2, 

at 8.4 % cPAD, using a POD based upon the toxicity of chlorpyrifos. The exposure for 

the general U.S. population from food without FHE use was 3.0 %cPAD. For food with

FHE use included the exposure for the general U. S. population was 3.7% cPAD, and for 

the most highly exposed population subgroup, children 1-2, was 11% cPAD. 

For water alone for the lower end representative sugar beet scenario selected by the 

assessment team, exposure for the general U. S. population at the maximum application 

rate was 21% cPAD using a POD based upon the toxicity of chlorpyrifos oxon; for the 

most highly exposed population subgroup, all infants, exposure was 69 % cPAD. [For 

the average typical application rate for sugar beets the general population was at 82% 

cPAD and all infants were at 270% cPAD.] The high end realistic water scenario for 

grapes selected by the assessment team exceeded the cPAD for all population subgroups, 
Chlorpyrifos Dietary Exposure and Risk Assessment DP Number: D388166

PC Code: 059101

______________________________________________________________________________________

Page 15 of 128

at 270% cPAD for the general population and at 890% cPAD for all infants, the most 

highly exposed population subgroup. [For the average typical application rate for grapes 

the general population was at 7.9% cPAD and all infants were at 26% cPAD.] In an 

intermediate corn/soybean water runoff scenario the cPAD for the general population was 

84% cPAD and for infants it was 280% cPAD. [For the average typical application rate 

for corn (only) the general population was at 15% cPAD and all infants were at 49% 

cPAD.]

The results of the chronic food dietary exposure analysis are reported in column 1 of 

Table 8 below. As can be seen, residues do not exceed the cPAD for any population 

subgroup. Column 1 food exposures are based only upon field use of chlorpyrifos and do

not incorporate exposure from food handling establishment (FHE) uses. Estimated 

potential exposures from FHE uses were assessed separately from other food exposure as 

a matter of convenience and are provided in column 2 of Table 8, but are additive to the 

other food exposures. Therefore, column 3 of Table 10 shows the total chronic food plus 

FHE exposure. We note while food alone is less than the cPAD even under the most 

conservative of conditions, food plus FHE would exceed the cPAD if an additional 10X 

factor is invoked. In addition to this potential toxicological uncertainty, it should be 

mentioned that there is considerable uncertainty in the exposure estimates for FHE as 

well. There are at least 2 currently registered FHE uses, but BEAD has been unable to 

estimate a percent FHE treated and has defaulted to its minimum of 2%. In addition the

expected FHE residues are based upon an FHE residue study with no detectable residues.

VII. Characterization of Inputs/Outputs

Residues for this assessment are almost all taken directly from PDP monitoring. For 

apples and grapes there is some concern about older PDP data because, although the 

labels were changed to allow only dormant uses on these crops in 2001, the tolerances 

were not changed until 2008. For that reason only data from 2009 PDP monitoring was 

used for these crops and residues can be assumed to be representative of actual residues 

in the food supply. Residues are high in leafy Brassica because PDP monitoring shows 

them to be high. For peaches, plums, nectarines and peppers PDP data show that most 

detectable residues are coming from imported crops, not domestic crops. PDP 

monitoring also shows real residues on a number of crops for which chlorpyrifos has no 

registered uses. It is not HED policy to include such crops in a dietary exposure 

assessment, but their existence indicates that the current assessment may somewhat 

underestimate actual exposure from food crops. 

This is a highly refined assessment, using monitoring data for almost all crops, using 

extensive percent crop treated information, and using a large set of processing and 

cooking factors. 

Sensitivity analyses indicate that non-detects contribute little to acute exposure. Most of 

the acute exposure is from detectable residues. This assessment did use tolerance level 

residues for kiwi because existing monitoring data are far out of date, but a quick 

sensitivity analysis setting all kiwi to zero indicated that this conservatism also

Page 18 of 128

contributed little to the overall acute food exposures and CEC analyses also did not point 

to kiwi as a driver.

VIII. Conclusions

Highly refined acute and chronic dietary exposure assessments have been done for food 

without FHE, for food with FHE (chronic only) and for drinking water. The acute food 

only exposures and chronic food exposures both with and without FHE were below 100% 

of the aPAD and cPAD, respectively, for all population subgroups. 

Drinking water is the clear driver in all of these assessments. It is assumed that drinking 

water has been treated with strongly oxidizing sanitizers (such as chlorine), a common 

practice, and that therefore all residues in drinking water occur as the oxon. Drinking 

water has here been assessed to chlorpyrifos – oxon based cPADs and aPADs. Residues 

modeled in drinking water exceed the aPAD for at least one population subgroup (all 

infants) for all three maximum rate and 2 of 3 typical rate scenarios evaluated here; and 

the residues exceed the aPAD for the other population subgroups in the two higher 

maximum rate scenarios and for children in the typical sugar beet scenario. Residues in 

drinking water also exceed the cPAD for the two higher scenarios at the maximum rate 

and again for iinffants and small children in the sugar beet typical rate scenario and 

cPAD.

GENERAL COMMENT

A revision of tolerances for chlorpyrifos was proposed in the Federal Register in 2007 (FR 72, #152, 8 August 2007, p. 44442) and 

published in 2008 in the Federal Register (FR 73, #181, 17 September 2008, p 53739). This revision included an extensive set of 

changes. A tolerance on the tree nut crop group was reduced to almond, hazelnut, pecan and walnut only. Tolerances on Cherimoya, 

Feijoa, Sapoa, Blueberry, Leek and Tomato were removed; a tolerance on Lettuce was added; and tolerances for apples and grapes 

and numerous other crops/commodities were reduced. It is too soon to see all of the effects of these changes in residue monitoring 

programs. In the case of apple and grape, the labeled application procedures governing domestic use were changed circa 2002, while 

the tolerance changes that regulate those crops when imported were only changed in 2008. For these reasons, the residue exposures 

assessed here required some unusual adjustments to provide the most accurate estimate of exposure through food as it is expected in 

the wake of these changes. In addition, a comparative assessment has also been done that incorporates unadjusted residues as seen in 

the most recent monitoring in order to provide an upper bound to the residues as they actually appear to have existed over the past 

several years and at the time of this assessment.

OTHER COMMODITIES

ASPARAGUS 

BEAD estimates a maximum of 45% crop treated for asparagus and an average percent crop treated of 30%.

USDA’s PDP analyzed 1117 fresh asparagus samples during the years 2008-9. Of these samples, 30 contained detectable residue 

levels and the remainder were reported as non-detects. The sum of these detects is 2.8213. Of the non-detects, 299 had a 1/2LOD of 

0.001 ppm and 787 had a 1/2LOD of 0.01 ppm, for a weighted average 1⁄2 LOD of 0.0073. For a chronic estimate, based on 30% crop 

treated, [(305*0.0073 + 2.8213]/1117 = 0.0045 ppm. For the acute assessment, TOTALZ= 1117* 0.55 = 614. There are the 30

detects plus 473 results at the weighted average 1⁄2 LOD of 0.0073 ppm. 

CANNED ASPARAGUS

USDA’s PDP analyzed a total of 354 canned asparagus samples during the year 2003. Of these samples, only 6 contained detectable 

residue levels and the remainder were reported as non-detects. The reported residues in the PDP data range from 0.0063 to 0.029 ppm 

and sum to 0.0672 ppm. Based on 30% crop treated, 106 of the 354 samples were likely treated. If 6 samples contained finite 

residues; 100 samples are assumed to contain residues at 1⁄2LOD (0.0019 ppm), with the remaining samples assumed at 0. Thus

Chronic AR = [0.0672 + (100 x 1⁄2 x 0.0038 ppm) + 0]/354 = 0.0007 ppm.

For the acute assessment, assuming 45% CT, an TDF is created with TOTALZ=195; there are 6 detects, and 153 at 0.0019.

BANANA/PLANTAINS

Because virtually all bananas are imported, BEAD percent crop treated estimates are not available for banana, so these are assumed to 

be 100% treated. USDA’s PDP analyzed a total of 1486 banana samples during the years 2006-2007. Of these samples, three

contained detectable residues, all at 0.0063 ppm, and the remainder are non-detects with an LOD of 0.0038. (Note that PDP does peel 

bananas prior to analysis.) The chronic AR is calculated as: Chronic AR = [1483 samples at 1⁄2 LOD of 0.0019 + 0.0189]/1486 = 

0.002 ppm. An acute RDF is created with 1483 samples at 0.0019 ppm and three detects, no zeroes.

COTTONSEED OIL

There are no monitoring data for cottonseed oil so data from the field trials, yielding an average residue of 0.12 ppm and a processing 

study yielding a processing factor of 0.375 were used. BEAD calculated that the maximum and average treatment rate for cotton was

<2.5%. From this a residue value of 0.003 ppm was calculated for both acute and chronic assessment, and this along with the

processing factor of 0.375 was used for both assessments.

CRANBERRY

BEAD estimates that a maximum of 70% crop treated for cranberry. The cranberry average percent crop treated was not calculated by 

BEAD, but cannot be higher than 70%..

USDA’s PDP analyzed a total of 316 cranberry samples during the year 2006. Of these samples, 71 contained detectable residue

levels and the remainder were reported as non-detects. The LOD range is 0.004 – 0.0049 ppm. The mean 1⁄2 LOD is 0.0024 ppm. 

For Acute NB/PB

70% crop treated X 316 Samples = 221 Samples with expected residues

# 1⁄2 LOD = 221 expected detects – 71 actual detects = 150 

Acute AR = [71 Detects + 150 non-detects at 1⁄2 LOD (0.0024) + 95 zeros] = Cranberry.RDF

For Chonic NB/PB/B

70% crop treated X 316 Samples = 221 Samples with expected residues

# 1⁄2 LOD = 221 expected detects – 71 actual detects = 150 

Chronic AR = [71 Detects + 150 non-detects at 1⁄2 LOD (0.0024)]/316 = 0.0068 point estimate

Cranberry Juice uses the cranberry data with a processing factor of 0.3 translated from the grape juice factor.

FIGS

Tolerance level residues (0.01 ppm) and 100% crop treated were used for figs

GRAPES 

BEAD estimates that a maximum of 15% crop treated for grapes and an average percent crop treated of 5%. PDP data for 744 

samples of fresh grapes is available from 2009. This dataset was used with the exclusion of all earlier data. In order to mitigate 

exposure through grapes, the label instructions were changed shortly after reregistration in 2000 to allow only a dormant ground use of 

chlorpyrifos on grapes, however the actual tolerance was not changed until 2008, after completion of the full cumulative assessment 

for organophosphate pesticides. Therefore residues on grapes, especially for imported grapes, prior to 2008 might not be completely 

representative of current exposure, but 2009 should be adequately representative of all changes. Although registered labels regulate 

domestic use, U.S. regulation on imported use is mainly through the tolerances. 

As stated, in 2009 PDP tested 744 samples of grapes for chlorpyrifos with an average LOD of 0.0078 ppm (1/2 LOD = 0.0039 ppm). 

There were 9 detects, summing to 0.066 ppm (and as general information, only 2 of these were from domestic grapes, the remainder of 

the detects and the highest residues all coming from imported grapes). From this information an acute RDF was created consisting of 

the 9 detects, 103 samples at 0.0039 ppm and 632 zeroes. A chronic AR was calculated as (0.199 + 402*0.0007)/744 = 0.00024 ppm. 

In 2009 PDP tested 744 samples of grapes

GRAPE JUICE

In 2008 PDP tested 745 samples of grape juice for chlorpyrifos with no detects. The LOD for 214 of the samples was 0.002 ppm and 

for the other 531 samples was 0.0051 ppm. BEAD estimated that 5%,on average, and 15% at a maximum, of the grapes are treated. 

From this a chronic AR was calculated at 0.0001 ppm. An acute rdf was created consisting 633 zeroes, 32 samples at 0.002 ppm and 

80 samples at 0.0051 ppm.

In 2007 PDP tested 744 samples of grape raisins with an LOD of 0.0051. There were 5 detects - three at 0.007 ppm and one each at 

0.022 ppm and 0.013 ppm, for a total of 0.056 ppm. BEAD estimated that 5% on average, and 15% at a maximum, of grapes are 

treated. Using this information a chronic AR of 0.0002 was calculated and a RDF was created consisting of 632 zeros, and 107 results 

at 1/2LOD, 32 at 0.002 and 75 at .004 ppm.

WINE

The 2009 grape RDF and AR are used, but a wine processing factor of 0.02 is used. This factor is discussed in detail in D. 

Soderberg’s, June 22, 2000 review. He notes that although different chlorpyrifos processing factors are available in the literature for 

both red and white wine; however, in DEEM these are not separate commodities and the more conservative processing factor of 0.02 

for white wine is applied.

KIWI FRUIT 

Tolerance level residues (2.0 ppm) were used for kiwi fruit. BEAD estimated a maximum of 2.5 % crop treated and an average of 1%. 

Thus the chronic AR is 0.02 ppm and an RDF was created consisting of 25 values at 2.0 ppm and 975 zeroes. Because Kiwi are 

almost always peeled prior to eating, a peeling factor of 0.15 was also applied.

MINT & MINT OIL

Tolerance level residues (8.0 ppm) and BEAD’s estimate of average and maximum 25% crop treated were used for mint and mint oil 

to yield an AR of 2.0 ppm 

PEANUTS

Peanut data were described in HED Memorandum D220463 written by Steve Knizner. Residues of chlorpyrifos in/on peanuts in field 

trials were <0.01 ppm, <0.01 ppm, <0.01 ppm, 0.01 ppm, and 0.01 ppm. Peanuts are considered to be a blended commodity and 

BEAD estimates of percent crop treated are an average of 5% and a maximum of 10%. Averages for acute (0.007 ppm) and chronic 

exposure (0.00035 ppm) were calculated using the five residue values with three at 1⁄2 LOD and invoking the percent crop treated for 

acute and chronic exposure. A processing factor of 2 was used for peanut oil.

In 2006 PDP tested 739 samples of peanut butter for chlorpyrifos with an LOD of 0.027 ppm and no detects. Because peanut butter is 

blended, based up these results an acute and chronic AR was created at the 1⁄2 LOD of 0.0135. 

STRAWBERRY

PDP tested 741 samples of fresh strawberries in 2008. There were seven detects , four at 0.003 ppm and one each at 0.014, 0.0097, 

and 0.0069 ppm, summing to 0.043 ppm. Of the non- detects, 210 had LOD at 0.005 ppm and 524 at 0.002 ppm. BEAD estimated 

that a maximum of 30% and an average of 15% of strawberries are treated. Therefore an acute RDF was developed with 

TOTALZ=514, the 7 detects, 156 at 1/2LOD of 0.0025 ppm and 64 at 1/2LOD of 0.001 ppm. A chronic AR was estimated at [0.043 

+ 78*0.0025 + 32*0.001]/741 = 0.00036 ppm. 

ROOTS AND TUBERS

PDP data exist only for sweet potatoes and onions. FDA data are way too few to use. 

SUGAR BEETS

BEAD estimates that a maximum of 20% crop treated for sugar beets and an average percent crop treated of 10%.

PDP has not tested sugar beets. Although PDP has tested sweet potatoes, the PHI is longer that for sugar beets, there is no crop group 

tolerance and it is not known if residues on the two crops are similar. The current sugar beet tolerance is based upon total TCP, not 

upon residues of chlorpyrifos, per se. However the total residues measured as TCP provide an upper limit for the amount of 

chlorpyrifos that may be present. In addition there is a sugar beet processing study (MRID 0039641) that shows that sugar beet roots 

fortified with 1 ppm chlorpyrifos, per se, have detectable residues of that compound at 0.48 ppm. After processing these same 

residues of chlorpyrifos, per se, are reduced to <0.01 ppm in both the refined sugar and the molasses. The resulting factor of 0.02 was 

applied to the tolerance of 1 ppm and corrected for an average 10% crop treated to come up with a residue of 0.002 that was used for 

both sugar beet sugar and sugar beet molasses blended commodities in both the chronic and acute assessments. This result was the 

best available way to estimate residues on sugar beet at this time. Sugar beet field trials measuring parent with a processing study 

using incurred residues should be submitted.

RADISH, RUTABAGAS and TURNIPS 

Translated from PDP data for sweet potatoes, assuming 100% crop treated. The average chronic AR was therefore 0.0016 ppm. The 

acute residue file consisted of the 165 detects and 1309 results at the 1⁄2 LOD of 0.0011 ppm.

SWEET POTATO

In 2003. 2004 and 2008 PDP tested 1474 samples of sweet potatoes with a total of 165 detects and with an average LOQ of 0.0022

ppm and a maximum of 65% crop treated. For this assessment the average % crop treated is also assumed at 65%. A 0.15 peeling 

factor was used. From this an RDF was created consisting of 516 zeros, 793 at 0.0011 ppm and the 165 detects. The average AR was 

0.0012 ppm. (Note that the percent detects and the concentration of detects both appear to decrease significantly from 2003 to 2008, 

but it is not clear at this time why this decrease appears to happen or whether it is a permanent difference or just a fluctuation or 

analytical artifact.) 

LEAVES OF ROOTS AND TUBERS

TURNIP TOPS 

In the absence of a more appropriate source of data the residues on kale (see leafy Brassica below) were translated to turnip tops. This 

translation should be very conservative. 

BULB VEGETABLES

ONION 

BEAD estimates that a maximum of 50% crop treated for onion and an average percent crop treated of 35%.

USDA’s PDP analyzed a total of 432 onion samples during the year 2002 - 2003. Of these samples, none contained detectable residue 

levels and the remainder were reported as non-detects. The LOD is 0.01 ppm. The 1⁄2 LOD is 0.005 ppm.

An RDF is created consisting of 216 zeroes and 216 values at 1⁄2 LOD = 0.005 ppm.

An acute AR at 0.0025 ppm is calculated. 

For Chonic NB/PB/B

GARLIC AND SHALLOTS

Assume 100% of the crop is treated so that all residues are at 1⁄2 LOD. Therefore an RDF is not needed and an AR of 0.005 ppm is 

used for both the acute and chronic assessments. 

LEAFY VEGETABLES

LETTUCE 

The current tolerance of 2.0 ppm in lettuce does not derive from any known source, was not supported by registrant, and is being 

cancelled. Lettuce is not included in the assessments.

BRASSICA

BROCCOLI

BEAD estimates that a maximum of 60% crop treated for broccoli and an average percent crop treated of 50%.

Page 43 of 128

USDA’s PDP analyzed a total of 1475 broccoli samples during the years 2006-2008. Of these samples, 108 contained a detectable 

residue level and the remainder were reported as non-detects. The LOD is 0.0012 ppm. Based on 60% crop treated 885 of the 1475 

samples were likely treated. An RDF was created consisting of 108 samples containing finite residues, 777 samples are assumed to 

contain residues at 1⁄2 the LOD of 0.0006 ppm, and 590 samples assumed at zero. The sum of the detects in the 108 samples was

0.4601 ppm and at 50% samples treated, on average, there should be 738 samples assumed to be at 1⁄2 LOD of 0.0006 ppm, so a 

chronic AR was calculated as

Chronic AR = [0.4601 + (738 x 0.0006 ppm)]/1475 = 0.0006 ppm

BRUSSELS SPROUTS, KOHLRABI

BEAD percent crop treated estimates are not available for Brussels sprouts, so these are assumed to be 100% treated. There is no PDP 

data for Brussels sprouts, so residues are translated from PDP data for broccoli. 

As above, USDA’s PDP analyzed a total of 1475 broccoli samples during the years 2006-2008. Of these samples, 108 contained a 

detectable residue level and the remainder were reported as non-detects. The LOD is 0.0012 ppm. Based on 100% crop treated all of 

the samples were likely treated. An RDF was created consisting of 108 samples containing finite residues and 777 samples are 

assumed to contain residues at 1⁄2 the LOD of 0.0006 ppm, with no samples assumed at zero. The sum of the detects in the 108 

samples was 0.4601 ppm and at 100% of samples treated, on average, a chronic AR was calculated as

Chronic AR = [0.4601 + (738 x 0.0006 ppm)]/(108 + 738) = 0.0011 ppm

COLLARDS

In 2006 – 2008 PDP analyzed 679 samples of collards with 22 detects and 1⁄2 LOD of 0.002 ppm. BEAD was unable to provide a 

percent crop treated for collards. Thus an RDF was created consisting of 657 values at 1⁄2 LOD of 0.002 ppm and 22 detects. An 

average AR was calculated of 0.0126. (Note that a single unusual above tolerance value of 6.3 ppm was reported in the PDP data for 

collards. While this value is not generally inconsistent with a pattern of generally significant residues on leafy Brassica, to assure a 

single value doesn’t inordinately affect all residue values in this crop group, the collards distribution was used only for collards. To be 

sure of the integrity of results, at HED’s request PDP also rechecked this value, and confirmed that the result is reported correctly and 

is not an error in units.)

KALE

In 2006 – 2008 PDP analyzed 802 samples of kale with 36 detects and 1⁄2 LD of 0.002 ppm. BEAD was unable to find and provide % 

crop treated value for kale. An RDF was thus created that consisted of 766 values at 1⁄2 LOD of 0.002 ppm and 36 detects. An 

average AR was calculated at 0.0049 ppm. 

OTHER LEAFY BRASSICA

The kale value was also applied to the other leafy Brassica, such as mustard greens and rape greens. 

HEAD AND STEM BRASSICA 

CABBAGE

BEAD estimates that a maximum of 25% crop treated for cabbage and an average percent crop treated of 10%.

BEAD percent crop treated estimates are not available for kohlrabi and mustard greens, so these are assumed to be treated at 100%. 

USDA’s Pesticide Data Program (PDP) analyzed a total of 1475 broccoli samples during the years 2006-2008. Of these samples, 108 

contained a detectable residue level and the remainder were reported as non-detects. The LOD is 0.0012 ppm. Based upon 25% crop 

treated an RDF was created that consisted of 108 detects, 777 samples at the 1⁄2 LOD of 0.0006 ppm and 2655 zeroes. A chronic AR 

was calculated as:

Chronic AR = (0.4601 + 738*0.0006/8460 = 0.00011 ppm.

CAULIFLOWER

BEAD estimates that a maximum of 65% crop treated for cauliflower and an average percent crop treated of 40%.

USDA’s PDP analyzed a total of 1424 cauliflower samples during the years 2004-2006. Of these samples, 8 contained a detectable 

residue level and the remainder were reported as non-detects. The LOD is 0.001 ppm. With 8 containing finite residues and acute

DRF was created consisting of 918 samples at the 1⁄2 LOD of 0.0005, 498 samples set to zero and the 8 finite residues. For the chronic 

analysis an AR of 0.00022 ppm was calculated. 

LEGUMES

GREEN BEANS

BEAD estimates that a maximum of 5% crop treated for green beans and an average percent crop treated of 2.5%.

Chlorpyrifos is used as a seed treatment on beans and peas. All tolerances are based on non-detectable residues in beans/peas as a 

result of the seed treatment.

USDA’s Pesticide Data Program (PDP) analyzed a total of 729 fresh green bean samples during the years 2004 and 2005. Of these 

samples, one contained a detectable residue level of 0.007 ppm and the remainder were reported as non-detects. The average LOD is 

0.0046 ppm, so the average 1⁄2 LOD is 0.0023. Based upon an average 2.5% crop treated there should be 18 samples treated, so the 

detect at 0.007 plus 17 samples at 0.0023 divided by 729 samples leads to a chronic estimate of 0.00006 ppm.

Based on 5% crop treated, 36 samples were considered to have been treated. Since only one contained a finite residue at 0.007 ppm; 

35 samples are assumed to contain residues at 1⁄2 the LOD of 0.0023 ppm. Therefore an RDF for the acute analysis contains one detect 

at 0.007, 35 samples at 0.0023 ppm and 693 zeros. 

[PDP also tested 555 samples of frozen green beans in 2005 with results so very similar that it is not worthwhile to create a separate 

chronic residue value or RDF for the frozen beans, so the above is also used for frozen beans.]

CANNED GREEN BEANS

USDA’s PDP analyzed a total of 928 canned green bean samples during the years 2003 and 2004. Of these samples, none contained 

detectable residue levels and the remainder were reported as non-detects. The LOD is 0.0047 ppm. All non-detect samples assumed 

the 1⁄2 LOD value of 0.0024 ppm. For the chronic assessment, at 1% crop treated, 9 samples are assigned the 1⁄2 LOD value of 0.0024, 

the rest assumed to be zero and the result averaged to

Based on 5% crop treated, 46 samples were considered to have been treated. None contained finite residues; therefore 46 samples are 

assumed to contain residues at 1⁄2 the LOD samples (LOD=0.0047 ppm) and the rest to have no residues. The specific input for canned 

green beans for the acute analysis involved creating a RDF of 882 zeros, and 46 samples at 1⁄2 LOD of 0.0024. (Canned green beans 

are assumed to be partially blended.)

OTHER SUCCULENT BEANS AND PEAS

In 2003 and 2006 PDP tested a total of 1293 samples of frozen succulent sweet peas.

In 2003 there were 549 samples of frozen sweet pea samples with no detects and 1⁄2 LOD of 0.002. In 2006 there were 744 samples of 

frozen sweet peas with no detects and 1⁄2 LOD of 0.002. BEAD estimates 2.5 max percent crop treated at 1% average percent crop 

treated. Putting all of this together, all succulent pea food forms were assigned a chronic AR of 0.00002 ppm. An acute RDF was 

created consisting of 25 values at 0.002 ppm and 975 values at zero. 

In the absence of data for lima beans and other succulent beans, the succulent pea results were also translated to these crops. BEAD 

estimates 2.5 max percent crop treated at 1% average percent crop treated, so the green peas’ results are used without change. 

DRIED BEANS AND PEAS

BEAD estimates that a maximum of 2.5% crop treated for dry beans/peas and an average percent crop treated of 1%.

Chlorpyrifos is used as a seed treatment on dried legume commodities, e.g., beans and peas with a tolerance of 0.05 ppm. All 

tolerances are based on non-detectable residues in field trials from the seed treatment. Because all field trial residues were nondetects, 1⁄2 the tolerance was used combined with the percent crop treated to generate point estimates of 0.00025 ppm for chronic and 

0.00063 for the acute assessments.

In 2008 PDP also tested 186 samples of canned kidney beans. All samples were non-detect, 52 with an LOD of 0.002 and 110 with an 

LOD of 0.025 ppm. For the chronic estimate this yields an average results of 0.0001 ppm after invoking 1% crop treated and using 

the average of the two 1⁄2 LODs. Because canned beans are also a blended commodity, and also because all results were non-detects, a

Page 47 of 128

point estimate based upon the weighted average of the two LODs for the acute assessment could be calculated at 0.01 ppm. However, 

this residue is artificially raised because monitoring data must be assumed to be 100% crop treated. Therefore the value of 0.00063 

from the dried bean field trials was used because this approach would allow incorporation of the 2.5 % crop treated estimate.

SOYBEAN

In the years 2004-2005 PDP tested 1263 samples of soybeans for chlorpyrifos with a 1⁄2 LOD of 0.0015 ppm and detected residues in

272 of these samples. The residues in these 272 samples summed to 2.218 ppm. Soybeans are considered to be a blended commodity 

and BEAD estimates of percent crop treated are an average of 5% and a maximum of 10%. The number of detects exceeded the 

number of samples expected to be treated at both 5% and 10%. Therefore an average residue for both the chronic and acute 

assessments was calculated as (2.218 + 991*0.0015)/1263 = 0.0029 ppm. 

FRUITING VEGETABLES

PEPPERS

BEAD has estimated that a maximum of 5% and an average of 2.5% of peppers are treated with chlorpyrifos. In the years 2002-2004 

PDP tested 1485 samples of bell peppers and encountered 241 detects, summing to 13.506 ppm with an LOD of 0.0012 ppm, or 1⁄2 

LOD of 0.0006 ppm. Based upon this an RDF was created consisting of the 241 detects, no LOD samples, and 1244 zeroes. There 

were no LOD samples because the number of detects greatly exceeded the number theoretically treated. For the chronic assessment 

an average point estimate of 13.506/1485 = 0.0091 ppm was calculated. These results were also translated to non-bell peppers. 

TOMATOES

All uses of chlorpyrifos on tomatoes have been cancelled. With the tomato tolerance revoked the anticipated residues for acute and 

chronic chlorpyrifos are set to zero. We note, however, that information from BEAD indicates <1 to <2.5% of the tomato crop is still 

reported as being treated with. Further, USDA’s PDP analyzed a total of 1486 tomato samples during the years 2000-2005. Of these 

samples, 49 contained detectable residue levels higher than the expected 37 based on percent crop treated, so the proportion of positive 

findings even exceeded the proportion of the crop estimated to have been treated. Thus, there may be some exposure through 

tomatoes that has not been calculated into these assessments.

CUCURBIT VEGETABLES

CUCUMBER/PUMPKIN

BEAD estimates that a maximum of 5% crop treated for both cucumber and pumpkins and an average percent crop treated of <2.5 for 

both cucumbers and pumpkins.

USDA’s PDP analyzed a total of 744 cucumber samples during the year 2009. Of these samples, 26 contained detectable residue 

levels, summing to 0.328 ppm, and the remainder were reported as non-detects. The average 1⁄2 LOD is 0.0007 ppm. These data were 

used for both pumpkins and cucumbers.

For the acute assessment, based on 5% crop treated, 37 of these samples were considered to have been treated. Because 26 contained 

finite residues; 11 samples are assumed to contain residues at 1⁄2 the LOD (0.0007 ppm). The specific RDF for the acute analysis 

therefore contains 707 zeros, 11 samples at 0.0007 ppm and the 31 detectable residues. For the chronic assessment the number of 

detects exceeded the percent crop treated so an average was calculated from the sum of the 26 detects (0.328)/744 = 0.00044 ppm.

CITRUS

ORANGE

BEAD estimates that a maximum of 35% crop treated for oranges and an average percent crop treated of 15%.

USDA’s Pesticide Data Program (PDP) analyzed a total of 1483 orange samples during the years 2004 and 2005. Of these samples, 

34 contained detectable residue levels, summing to 0.248 ppm and the remainder were reported as non-detects. The average LOD is 

0.004 ppm. From this a chronic residue was calculated at (0.248 + .002*188)/1483 = 0.0004 ppm. An RDF was created for the acute 

assessment consisting of the 34 detects, 485 results at 0.002 ppm and 964 zeroes.

Page 49 of 128

USDA’s PDP analyzed a total of 1517 orange juice samples during the years 2004, 2005 and 2006. Of these samples, 4 contained 

detectable residues, all at 0.007 ppm, and the remainder were reported as non-detects. The average LOD is 0.004 ppm. From this a 

chronic point estimate was made at (4*.007 + 224*.002)/1517 = 0.0003 ppm. An acute RDF was created consisting of the 4 detects, 

527 at 0.002 ppm and 986 zeroes. Note that orange juice concentrations were translated to other juices using adjustment factors as 

spelled out in DESAC policy: 1.17 for grapefruit juice, 1.11 for lime juice and lemon juice and 1.28 for tangerine juice.

TANGERINE

BEAD estimates that a maximum of 25% crop treated for tangerines and an average percent crop treated of 15%. Results are 

translated from PDP orange data. The chronic value remains the same as for oranges because it is the same percent crop treated.

An RDF was created for the acute assessment consisting of the 34 detects, 485 results at 0.002 ppm and 1557 zeroes. (The zeros are 

estimated by summing 34 + 485 = 519, then divide by 0.25 = 2076 estimated total samples at 25% CT, then subtract the original 519 = 

1557 zeroes.)

TANGERINE JUICE

Tangerine Juice was translated from Orange Juice. Because the average percent crop treated for both is 15%, the chronic orange 

juice residue was not adjusted for tangerine juice and equals 0.0003 ppm. For the acute assessment the RDF was adjusted from 35% 

to 25% maximum percent crop treated. Thus an acute RDF was created (as above) consisting of the 4 detects, 527 at 0.002 ppm and 

1593 zeroes.

LEMONS

BEAD estimates that a maximum of 60% crop treated for lemons and an average percent crop treated of 35%.

PDP orange data were translated to lemons and adjusted for percent crop treated estimate for lemons.

BEAD estimates that a maximum of 35% crop treated for oranges and an average percent crop treated of 15%.

Page 50 of 128

Thus a chronic residue was calculated as 35/15*.00042 = 0.0010 ppm An RDF was created for the acute assessment consisting of the 

34 detects, 485 results at 0.002 ppm and 346 zeroes. 

LEMON JUICE 

Lemon Juice was translated directly from Orange Juice. Because the average percent crop treated for lemons is 35% and that for 

oranges is 15%, the orange juice residue was adjusted for the different percent crop treated to yield 0.0003 *35/15 = 0.0007 ppm. For 

the acute assessment the RDF was also adjusted for relative percents crop treated. Thus an acute RDF was created consisting of the 4 

detects, 527 at 0.002 ppm and 354 zeroes.

OTHER CITRUS: LIME POMMELO, CITRON, etc

BEAD did not provide usage data for these crops, therefore, HED makes the default assumption of 100% of these crops are treated 

both on average and at a maximum. Results are translated from PDP orange data. The chronic value for these crops is estimated at 

0.0028 ppm. 

An RDF was created for the acute assessment consisting of the 34 detects and 485 results at 0.002 ppm. 

CITRUS OIL

Citrus oil is just a place holder in DEEM; no consumption is reported. Because citrus oils are very commonly used as flavorants in 

beverages and candies, etc, but are used only in very trace amounts, actual frequency of consumption is very high, but the amounts 

consumed are miniscule. 

GRAPEFRUIT

BEAD estimates that a maximum of 35% crop treated for grapefruit and an average percent crop treated of 20%.

USDA’s Pesticide Data Program (PDP) analyzed a total of 1485 grapefruit samples during the years 2005 - 2006. Of these samples, 

24 contained detectable residue levels, summing to 0.0407 ppm, and the remainder were reported as non-detects. The average LOD is

0.00174 ppm, the average 1⁄2 LOD = 0.00087. An acute RDF was created consisting of the 24 detects plus 496 at .00087 ppm and 965 

zeroes. A chronic average was calculated as 0.0407 + .00087*273/1485 = 0.00019.

GRAPEFRUIT JUICE 

Grapefruit juice was translated from orange juice. The average percent crop treated for grapefruit juice is 20% while that for oranges 

juice is 15%, so the orange Juice residue was adjusted by the difference in percent crop treated. The orange juice average residue of 

0.0003 ppm was adjusted by 20/15 = 0.0004 ppm. For the acute assessment the percent crop treated are both 35%, so the orange juice 

RDF was used without change. 

OTHER CITRUS JUICES

The only other citrus juice in DEEM is lime juice. Lime juice was translated from orange juice. The average percent crop treated for 

lime is 100%, while the average % crop treated for orange juice is 15%. An average residue of 0.0003/.15 = 0.002 ppm was 

calculated. For the acute assessment the orange juice RDF was adjusted to tangerine juice using the relative percents crop treated 

Thus an acute RDF was created consisting of the 4 detects, 527 at 0.002 ppm and no zeroes.

POME FRUIT

APPLES

APPLES, FRESH

BEAD estimates that a maximum of 65% crop treated for apple and an average percent crop treated of 55%. PDP results for 744 

samples of fresh apples are available from 2009. This dataset was used with the exclusion of all earlier data. In order to mitigate 

exposure through apples, the label instructions were changed shortly after reregistration in 2000 to allow only a dormant ground use of 

chlorpyrifos on apples, however the actual tolerance was not changed until 2008, after completion of the full cumulative assessment 

for organophosphate pesticides. Therefore residues on apples, especially for imported apples, prior to 2008 might not be completely 

representative of current exposure, but 2009 should be adequately representative of all changes. Although registered labels regulate 

domestic use, U.S. regulation on imported use is mainly through the tolerances.

Page 52 of 128

As stated, in 2009 PDP tested 744 samples of apples for chlorpyrifos with an average LOD of 0.00145 ppm (1/2 LOD = 0.0007 ppm). 

There were 7 detects, summing to 0.199 ppm (and as general information, 3 of these were from domestic apples, the two highest 

residues both being domestic). From this information an acute RDF was created consisting of the 7 detects, 477 samples at 0.0007 

ppm and 260 zeroes. A chronic AR was calculated as (0.199 + 402*0.0007)/744 = 0.00065 ppm. 

PEELING FACTOR FOR APPLES (POME FRUIT)

The Residue Chemistry Chapter of the Registration Standard stated that the majority of chlorpyrifos residues in apples were found on 

the apple peel. It was determined that a reduction factor of 0.15X for peeling could be applied to whole apples when they were 

peeled. Whole cooked apples are expected to be peeled.

In the RED this peeling factor was also translated to pears, kiwi, and canned sweet potatoes. This analysis will make the same 

translations.

APPLE, JUICE

USDA’s PDP analyzed a total of 740 apple juice samples during the years 2007-8. Of these samples, none contained detectable 

residue levels. Since there were no detects the estimated residues are based upon the LOD, not upon real residues, yet apple juice is a 

critical commodity for exposure. Therefore the average residue for the 2009 apples, at 0.00065, was multiplied by the DEEM default 

concentration factor for juice 1.3 to yield an average result of 0.00085 and a peeling factor of 0.15 was incorporated. This yielded a 

more realistic estimate of the actual exposure.

APPLE, SAUCE

Similarly, USDA’s PDP analyzed a total of 714 apple sauce samples in 2006, and none of these samples contained detectable residue 

levels, so these results were also controlled by the limit of detection used in monitoring. For that reason, the value of 0.00065 from 

the 2009 apples was also used for apple sauce with a correction for a peeling factor of 0.15.

BEAD estimates a maximum of 30% crop treated for pears and an average percent crop treated of 25%

USDA’s PDP analyzed a total of 1483 fresh pear samples during the years: 2003, 2004 and 2005. Of these samples, 33 contained

detectable residue levels, summing to 0.4225 ppm, and the remainder were reported as non-detects. The average LOD is 0.0039 ppm.

Based on 30 crop treated, 445 samples were considered to have been treated for pear. Because 33 samples contained finite residues 

412 samples are assumed to contain residues at 1⁄2 the LOD of 0.0019 ppm. The specific RDF for the acute analysis contains 1038 

zeros, 412 samples at 1⁄2 LOD and the 33 detectable residues from the fresh pear PDP data. The chronic average residue was 

calculated at 0.0007 ppm. 

PEARS CANNED, and PEAR JUICE

Canned pears were last analyzed by PDP in 2000. Considering the age of this data and other factors, residue data for canned pears 

were translated from residue data for fresh pears. Thus the AR of 0.0007 was used for both the acute and chronic assessment. A 

peeling factor of 0.15 was used for pear juice and canned pears. 

STONE FRUITS

CHERRIES

BEAD estimates that a maximum of 45% crop treated for cherries and an average percent crop treated of 30%.

USDA’s PDP analyzed a total of 419 cherry samples in 2007 Of these samples, none contained a detectable residue. The average 

LOD was 0.0027, so the average 1⁄2 LOD was 0.00135 ppm. An acute RDF was created containing 189 samples at 1⁄2 LOD and 230 

zeroes. A chronic average result was calculated at 0.0004 ppm.

NECTARINES 

In 2008 PDP tested 672 samples of nectarines with an LOD of 0.005 ppm and found 67 detects totaling to 0.719 ppm. BEAD has 

estimated that a maximum of 35% of nectarines are treated and an average of 20% are treated. Based upon this a chronic value of

(0.719 + 67*.0025)/672 = 0.0013 was calculated. An acute RDF was created consisting of the 67 detects, 168 values at 0.0025 and 

437 zeros.

PEACHES 

In the years 2006, 2007 and 2008 PDP tested 1261 samples of fresh peaches with 218 detects summing to 3.72 ppm. Average of LOD 

was 0.0078 ppm. BEAD calculated that on average 30% and at a maximum 40% of peaches are treated. Based upon this information 

a chronic result of 0.0038 ppm was calculated for fresh peaches and an acute RDF was created consisting of 757 zeroes, 218 detects 

and 286 at 0.0039.

PDP also tested 1485 samples of canned peaches in 2003 – 2004 with no detects, and an LOD of 0.01. A chronic residue of 0.0015 

ppm was estimated from this data. An acute RDF was created with 891 zeroes and 594 at 0.005. These values were applied to peach 

juice as well as to canned peaches.

PLUMS 

In the years 2005-2006 PDP tested 1088 samples of fresh plums and found 130 detects adding to a total 2.132 ppm. There were 402 

samples tested with an LOD of 0.003 and 556 samples with an LOD of 0.008 ppm. BEAD determined that 15% of the plum crop is 

treated on average and 25% at a maximum. A chronic estimate of 0.002 ppm was calculated based upon this information. For the 

acute assessment a RDF was created consisting of 130 detects, TOTALZ = 817, 101 results at 0.0015 ppm and 142 at 0.004 ppm. 

PRUNES and PRUNE JUICE 

In the years 2005-2006 PDP tested 377 samples of prunes. There were no detects. 194 of the samples had an LOD of 0.003 and 183 

had an LOD of 0.008 ppm. Based upon 15% of plums treated, a chronic value for prunes was calculated at 0.0004 ppm. Considering 

that 25% of plums are treated at a maximum, an acute RDF was created consisting of TOTALZ=282, TOTALFREQ=2, with 46 at 

0.004 and 49 at 0.0015 ppm. 

A dilution factor for translating the prune residues to prune juice of 0.28 was calculated based upon the ratio of solids in prunes (69%) 

to those in prune juice (19%) using composition values taken from USDA Nutrient Data for Standard Reference. Although this is not

a standard processing factor, it matches the procedure used to derive the standard concentration factors, and makes sense when one 

considers that prune juice is basically made from pureed prunes blended with water. 

TREE NUTS

In 2007 – 2008 PDP tested 547 samples of almonds for chlorpyrifos with an LOD of 0.001 ppm, and found 232 detects, summing to a 

total of 0.99777 ppm. These results can also be translated to filberts, pecans and walnuts. BEAD has reported that on average 20% of 

almonds are treated, and at a maximum 30% are treated. BEAD has reported that on average 35 percent, and at a maximum 45% of 

walnuts are treated; on average 15 percent, and at a maximum 25% of filberts are treated; and on average 30 percent, and at a 

maximum 40% of pecans are treated; 

An average chronic number for almonds is calculated from this as 0.99777/547 = 0.0018 ppm. The proportion of detects found by 

PDP, 232 of 547, greatly exceeds both the average and the maximum percent crop treated for almonds, so no 1/2LODs are used. 

When the almond data are translated to other nuts, this number is simply adjusted by the relative percents crop treated, so walnuts are 

at 0.0032 ppm; filberts are at 0.0014 ppm, and pecans are at 0.0027 ppm. 

An acute RDF for almonds is created with the 232 detects, and 315 zeroes. When the almond data are translated to other nuts, this 

number is adjusted by the relative percents crop treated, so walnuts are assigned 232 detects and 133 zeroes, filberts are assigned 232 

detects and 424 zeroes, and pecans are assigned 232 detects and 178 zeroes. 

Almond Oil and Filbert oil use the almond monitoring results with processing factors of 2.0 and 1.6, based upon the ratio of lipid to 

whole nut as listed in the USDA Nutrient Database for Standard Reference. http://www.nal.usda.gov/fnic/foodcomp/search/

SWEET CORN FRESH AND FROZEN

Chlorpyrifos Dietary Exposure and Risk Assessment DP Number: D388166

______________________________________________________________________________________

Page 56 of 128

USDA’s PDP analyzed a total of 928 sweet corn fresh and frozen samples during the year 2008 – 2009. None contained detectable 

residue levels and the remainder were reported as non-detects. There were two distinct LOD with 866 at 0.02 ppm and 263 0.002 

ppm. The 1⁄2 LODs are therefore 0.01 and 0.001 ppm. In this case, because there is no evidence of any residues in any sample, and 

because of the divergence of LODs, and given the high treatment rate should have allowed detectable residues to occur even in a 

relatively small number of samples, it seems most appropriate to use only the 263 samples tested to the 1⁄2 LOD of 0.001. At 20% crop 

treated this would lead to an RDF of 20 samples at the 1⁄2 LOD of 0.001 and 80 samples at zero. The chronic AR would be 0.00015 

ppm.

FIELD CORN GRAIN

In the years 2007 – 2008 PDP tested 1300 samples of field corn with 311 detects, summing to 0.949 ppm and an LOD of 0.001 ppm. 

Use of this PDP data leads to a residue of 0.00111 because of the assumption that all samples might include corn treated at 1⁄2 LOD = 

0.0005 ppm, and that percent crop treated cannot be invoked because corn grain is a blended commodity. This value was used for 

both chronic and acute assessments. This value was also applied to sorghum. Processing factors of 4.5 for corn oil, 0.05 for corn 

syrup and 0.22 for the washing of endosperm products were also applied. This result was also applied to sorghum grain and syrup.

WHEAT GRAIN

BEAD estimates that a maximum of 5% crop treated for wheat and an average percent crop treated of 2.5%.

USDA’s PDP analyzed a total of 1361 wheat grain samples during the years 2005-2006. Of these samples, 8 contained detectable 

residue levels (0.042 ppm and 7*0.010 ppm) and the remainder were reported as non-detects. The LOD is 0.006 ppm. Because wheat 

is a blended commodity, when using PDP data all non-detect samples must assume the 1⁄2 LOD value of 0.003 ppm. This is because 

one cannot infer how the percent crop treated affects the residues once they are blended, one can only take each measured residue at it 

face value. 

Acute and Chronic Blended –

Acute AR = 8 Detects + 1353 nondetects at 0.003 ppm.

Chronic AR = (8 Detects totaling 0.112 ppm + 1353 nondetects at 0.003)/1361 = 0.003 ppm point estimate

The value of 0.003 ppm was also applied to commodities processed from blended wheat in the acute assessment.

WHEAT FLOUR

BEAD estimates that a maximum of 5% crop treated for wheat and an average percent crop treated of 2.5%.

Although USDA’s PDP analyzed a total of 1311 wheat flour samples during the years 2003-2004, none contained detectable residue 

levels. The LOD is 0.006 ppm, so the 1⁄2 LOD is 0.003 ppm. But this approach leads to an over conservative estimate, so the direct 

wheat flour testing was not used. Instead, the most realistic estimation of residues on wheat flour is the PDP wheat grain residue (see 

above) of 0.003 ppm times a 0.145 processing factor.

Acute and Chronic Wheat Flour Blended – Translated from wheat grain results above at 0.003 ppm times a PF of 0.145.

OIL SEEDS

SUNFLOWER

Sunflower data were described in HED Memorandum D220463 written by Steve Knizner. The average residues level for all field 

trials was reported in this memo to be 0.046 ppm. 

Sunflower seeds are considered to be a partially blended commodity and BEAD estimates of percent crop treated are an average of 

2.5% and a maximum of 10%. Average residues for acute and chronic exposure were calculated from the residue values utilizing the 

average percent crop treated. This leads to a value of 0.00115 ppm for both chronic and acute assessments. The minimum

concentration factor of 2.5 was applied to sunflower oil.

MEAT, MILK, POULTRY AND EGGS

Because there are several routes through which animals may be exposed to residues of chlorpyrifos, via feeds, ear tags, dermal 

applications and applications to stalls and bedding; because on the other hand rapid metabolism makes the occurrence of residues

probable only if exposure occurs relatively shortly before slaughter; the best way to evaluate residues in meat milk poultry and eggs 

would be via monitoring programs. PDP monitoring data are listed in the table below. Only one detect, at 0.0025 ppm was found in 

hog fat for 352 hog fat samples, 592 beef fat samples, and 631 poultry fat samples in various years from 2000 2005. In 2006 an 

additional 655 poultry muscle (but no fat) samples were tested with no detects. USDA’s Food Safety and Inspection Service has 

monitored extensively for chlorpyrifos in fat (where chlorpyrifos residues are most likely to occur) in recent years for tolerance 

enforcement. There were no detections from almost 23000 samples from all livestock slaughter classes in data recorded from 2003 –

2008 ( see the following table), but the LODs were 0.1 ppm, near the tolerance..

BEEF ADIPOSE TISSUE (FAT)

BEAD estimates are not applicable to livestock commodities

In 2009 PDP analyzed 292 samples of beef adipose tissue with an LOD of 0.001 ppm and no detects. The result is an AR used in both 

the acute and chronic assessments of 0.0005 ppm (1/2LOD).

In addition, PDP analyzed a total of 592 frozen beef adipose samples during the years 2001-2002. Of these samples, none contained 

detectable residue levels and the remainder were reported as non-detects. The LOD is 2.8 ppb or 0.0028 ppm, with a 1⁄2 LOD = 0.0014

ppm. With no evidence of residues in either sampling HED is defaulting to the 1/2LOD of the most recent (2009) sampling at 0.0005 

ppm.

BEEF LIVER 

USDA’s PDP analyzed a total of 624 frozen beef liver samples during the years 2001-2002. Of these samples, 0 contained detectable 

residue levels and the remainder were reported as non-detects. The LOD is 2.8 ppb or 0.0028 ppm. All non-detect samples assumed 

the 1⁄2 LOD value of 0.0014 ppm. PDP did not analyze liver samples in 2009, but organophosphates are very labile in metabolically 

active tissues such as liver, and there is very little evidence of chlorpyrifos in any animal tissues. If anything the longest lifetime 

should be in beef fat. Therefore HED is translating the 2009 1⁄2 LOD value of 0.0005 ppm to beef liver and beef meat byproducts.

BEEF MUSCLE (MEAT) 

In 2009 PDP analyzed 292 samples of beef adipose tissue with an LOD of 0.001 ppm and no detects. The result is an AR used in both 

the acute and chronic assessments of 0.0005 ppm (1/2LOD).

In addition, PDP analyzed a total of 619 frozen beef muscle samples during the years 2001-2002. Of these samples, none contained 

detectable residue levels and the remainder were reported as non-detects. The LOD is 2.8 ppb or 0.0028 ppm, with a 1⁄2 LOD of 

0.0014. All non-detect samples assumed the 1⁄2 LOD value of 0.0014 ppm. With no evidence of residues in either sampling HED is 

defaulting to the 1/2LOD of the most recent sampling at 0.0005 ppm.

GOAT, SHEEP, RABBIT, GAME MEATS

The value of 0.0005 ppm was translated from beef to these other meats. 

VEAL AND HORSE MEATS

As in the last assessment, veal is assumed to contain no residues of chlorpyrifos. Veal are either fed entirely upon cow’s milk, or upon 

milk replacers. These latter, in turn, are generally made from certain milk products such as whey, and/or and purified soy products.

USDA’s PDP analyzed a total of 631 poultry adipose samples during the year 2000 - 2001. Of these samples, none contained 

detectable residue levels and the remainder were reported as non-detects. The LOD is 9.8 ppb or 0.0098 ppm. All non-detect samples

POULTRY LIVER 

BEAD estimates are not applicable to livestock commodities

USDA’s PDP analyzed a total of 634 poultry liver samples during the year 2000 - 2001. Of these samples, none contained detectable

Chronic AR = [0 Detects + 634 non-detects at 1⁄2 LOD (0.0049)]/634 = 0.0049 point estimate

POULTRY MUSCLE (MEAT)

In 2006 PDP tested 655 samples of poultry muscle (thigh and breast – it is unclear if both tissues are from the same birds). All 

samples were non-detects with an LOD of 0.0015 ppm. Therefore an AR of 0.00075 ppm was used for both acute and chronic 

assessments.

No testing has been done for residues of chlorpyrifos in eggs, but on the grounds that residues are not likely to be higher than those in 

muscle liver and fat, the same limit of 0.0049 ppm was applied to eggs. 

COOKING FACTORS FOR MEAT AND POULTRY

Meat and poultry are not normally consumed raw in the U.S., so application of a cooking factor is considered appropriate and provides 

a more realistic exposure assessment/ These assessments use a cooking reduction factor of 0.5X that was discussed in the RED.

Milk Products

Residues in milk and milk (dairy) products were assumed to be all zero, based upon no detections in 3600 samples in three sampling 

programs: a market basket study performed by DAS, USDA PDP pesticide monitoring samples and in FDA monitoring. In 2004-5 

PDP tested an additional 1485 milk samples with an LOD of 0.17 ppb and had no detects. In 2005 and 2007 PDP tested a total of 

1011 samples of heavy cream (about 37% fat) with no detects at an LOD of 1 ppb. In 2003 PDP tested 732 samples of butter (81% 

fat) with an LOD of 1.6 ppb and had one trace detect at 2.7 ppb. We note that chlorpyrifos is hydrophobic (log Ko/w = 4.7) and so is 

expected to concentrate in the fatty (butter, heavy cream) portions of milk. Thus there is strong evidence that no residues (or virtually 

none) occur in the portions of milk, expressed in DEEM as milk water, milk protein, milk fat. 

.

Please note that although residues in whole cow’s milk are expected to be negligible, it is possible that human breast milk may be 

significantly different, and may be more likely to have incurred residues. Dairy cows are on highly restricted diets, live out their milk 

production years at only one farm, and are bred to give milk extensively and at a young calendar age compared to humans. Very little 

data exists for residues in human milk, and human milk has not been typically addressed in EPA dietary exposure analyses, and it is 

not addressed here. It is this assessor’s understanding that efforts are under way to collect more and better data on residues in human 

milk. 

FOOD HANDLING ESTABLISHMENT USE

When a food handling tolerance exists, a chronic risk assessment must be performed that includes residues based upon the likelihood 

of contamination at food handling establishments. An acceptable food handling study has been submitted and the results indicate that 

all produce were non-detects, with an LOD of 0.02 ppm. BEAD has determined that there are no FHE uses reported at the limit of

sensitivity of their data at use in 2% of FHE establishments. Therefore, for the purposes of the chronic dietary exposure assessment, 

the 1⁄2 LOD of 0.01 ppm has been combined with an estimate that not more than 2% of the establishments are treated, to estimate that 

residues are 0.0004 ppm on all foods not already estimated to have residues from field treatment. (Note: although there is an FHE 

tolerance, at this time it appears that there are no longer any chlorpyrifos containing products that are labeled for FHE use. Therefore, 

including any FHE in this assessment is expected to be conservative.)

Attachment 3. Usage Information

Chlorpyrifos (059101)

Screening Level Usage Analysis (SLUA)

Date: March 10, 2010

What is a Screening Level Usage Analysis (SLUA)?

Available estimates of pesticide usage data for a particular active ingredient that is used on 

agricultural crops in the United States.

Pesticide usage data obtained from various sources. The data are then merged, averaged, and 

rounded so that the presented information is not proprietary, business confidential, or trade 

secret. 

What does it contain?

Pesticide usage data for a single active ingredient only.

Agricultural use sites (crops) that the pesticide is reported to be used on.

Available pesticide usage information from U.S. states that produce 80% or more of a crop, in 

most cases, or less than 80%, in rare cases, depending on the scope of the survey and 

available resources.

Annual percent of crop treated (average & maximum) for each agricultural crop.

Average annual pounds of the pesticide applied for each agricultural crop (i.e., for the states 

surveyed, not for the entire United States).

What assumptions can I make about the reported data?

Average pounds of active ingredient applied - Values are calculated by merging pesticide 

usage data sources together; averaging across all observations, then rounding. Note: If the 

estimated value is less than 500, then that value is labeled <500. Estimated values between 

500 & <1,000,000 are rounded to 1 significant digit. Estimated values of 1,000,000 or 

greater are rounded to 2 significant digits.)

Average percent of crop treated - Values are calculated by merging data sources together; 

averaging by year, averaging across all years, & rounding to the nearest multiple of 5. Note: 

If the estimated value is less than 2.5, then the value is labeled <2.5. If the estimated value is 

less than 1, then the value is labeled <1.

Maximum percent of crop treated - Value is the single maximum value reported across all 

data sources, across all years, & rounded up to the nearest multiple of 5. Note: If the 

estimated value is less than 2.5, then the value is labeled <2.5.

What are the data sources used?

USDA-NASS (United States Department of Agriculture’s National Agricultural Statistics 

Service) – pesticide usage data from 2001 to 2007.

Private pesticide market research – pesticide usage data from 2001 to 2007.

NPUD 2002 (National Pesticide Use Database) pesticide usage data from the CropLife 

America Foundation are used only if data are not available from the other sources.

California Department of Pesticide Regulation (DPR) Pesticide Use Reporting (PUR)

data for 2001 to 2007 when 95% or more of a crop is grown California.

What are the limitations to the data?

Additional registered uses may exist but are not included because the available surveys do not 

report usage (e.g., small acreage crops).

Lack of reported usage data for the pesticide on a crop does not imply zero usage.

Usage data on a particular site may be noted in data sources, but not quantified. In these 

instances, the site would not be reported in the SLUA.

Non-agricultural use sites (e.g., turf, post-harvest, mosquito control, etc.) are not reported in 

the SLUA. A separate request must be made to receive these estimates.

Some sites show some use, even though they are not on the label. This usage could be due to 

various factors, including, but not limited to Section 18 requests, existing stocks of the 

chemical, data collection errors, and experimental use permits (EUPs).

The Health Effects Division (HED) requested additional usage information for the chlorpyrifos

dietary exposure assessment. In this memorandum, BEAD is providing the percent crop treated

values for crops that were not reported on the March 10, 20 I0 Screening Level Use

Analysis (SLUA) and also updated values for the Percent of Food Handling Establishments

Treated (PFHET) Estimates.

PERCENT CROP TREATED VALUES

Pesticide use on succulent lima beans and k iwis was surveyed and chlorpyrifos use was not

reported . Therefore, following the reporting format of the SLUA, the average and maximum

values are <1% and <2.5%, respectively.

Usage data arc not available to determine a PCT value for kale or collard greens.

PERCENT OF FOOD HANDLING ESTABLISHMENTS TREATED

In 2008 , BEAD estimated that less than 2% of food handling establishments were treated 

with chlorpyrifos (Grube, 2008). This estimate was derived from market share (percentage 

of sales) of chlorpyrifos s products relative to market share for total products as found in 

2005 EPA proprietary data. This approach is based on the assumption that the sales volume 

(measured in dollars) of each of a group of alternative pest control products is representative 

of the use of each of these products.

BEAD reviewed more recent proprietary data (2008>for pesticide use in food handling

establishments and found that chlorpyrifos use was not reported. Following the market share

methodology, BEAD concludes that, given the reporting threshold for the 2008 data was 2% 

of the total sales and chlorpyrifos was not reported, then the value of 2% would provide an

upper bound estimate of chlorpyrifos use in food handling establishments.
