Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 2 of 49

Executive Summary

Acute and chronic dietary exposure and risk assessments were conducted for buprofezin using 

the Dietary Exposure Evaluation Model - Food Consumption Intake Database (DEEM-FCID , 

ver. 2.03). DEEM-FCID incorporates food consumption data from the United States 

Department of Agriculture (USDA) Continuing Surveys of Food Intakes by Individuals (CSFII; 

1994-1996 and 1998). This assessment is being conducted in support of new or expanded uses

of buprofezin on tree nuts (including pistachio); succulent beans; Brassica, leafy greens, crop 

subgroup 5B; turnip greens; fruiting vegetables, crop group 8-10; citrus fruit, crop group 10-10; 

pome fruit, crop group 11-10; persimmon; and tea (no U.S. registration).

Acute Dietary and Drinking Water Exposure Results and Characterization

A screening level acute dietary analysis was conducted for this assessment assuming 100% crop 

treated for all commodities. Total residues of concern in crop commodities (i.e., buprofezin and 

the BF4 Conjugate which is not detectable by data collection methods but which may be estimated 

from metabolism data) were based on tolerance level residues of buprofezin and available 

metabolism/magnitude of the residue data to estimate other residues of concern. Given the 

potential for BF9 and BF12 to concentrate to a greater degree than buprofezin in processed 

commodities, DEEM default processing factors were retained for all commodities, except for 

tomato paste and puree, which were reduced based on empirical data. Based on the submitted 

lemon metabolism data, which indicated that residues of concern are primarily found in/on the 

peel, the maximum theoretical concentration factor for peel was used to estimate residues of 

concern in citrus peel. Total residues of concern in meat (i.e., buprofezin and BF2) and milk (i.e., 

buprofezin and BF23) were based on the feeding study data which were used to establish meat and 

milk tolerances. Based on the submitted data, which indicated a 5x concentration of residues into 

milk cream and fat and a Log Kow of 4.31, a default 25x concentration factor was applied to milk 

fat. The acute analysis also incorporated the 1 in 10 year peak surface drinking water estimate 

resulting from application of buprofezin to coffee. The resulting acute exposure estimate for 

females 13-49 years old is not of concern to HED (5% acute population adjustment dose (aPAD)). 

No acute endpoint was identified for the remaining population subgroups. 

Chronic Dietary and Drinking Water Exposure Results and Characterization

A refined chronic dietary analysis was conducted for this assessment using percent crop treated 

estimates when available. Total residues of concern in crop commodities (i.e., buprofezin and the 

BF4 Conjugate which is not detectable by data collection methods but which may be estimated 

from metabolism data) were based on average field trial, average USDA Pesticide Data Program

(PDP), or tolerance level residues to estimate anticipated residues of buprofezin and available 

metabolism/magnitude of the residue data to estimate other residues of concern. Given the 

potential for BF9 and BF12 to concentrate to a greater degree than buprofezin in processed 

commodities, DEEM default processing factors were retained for all commodities, except for 

tomato paste and puree, which were reduced based on empirical data. Based on the submitted 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

lemon metabolism data, which indicated that residues of concern are primarily found in/on the 

peel, the maximum theoretical concentration factor for peel was applied to residues in citrus peel. 

Total residues of concern in meat (i.e., buprofezin and BF2) and milk (i.e., buprofezin and BF23) 

were based on the feeding study data which were used to establish meat and milk tolerances. 

Based on the submitted data, which indicated a 5x concentration of residues into milk cream and 

fat and a Log Kow of 4.31, a default 25x concentration factor was applied to milk fat. The chronic 

analysis also incorporated the 1 in 10 year average surface drinking water estimate resulting from 

application of buprofezin to coffee. The resulting chronic exposure estimates indicate no risks of 

concern general population or other population subgroups. The chronic risk exposure estimate for 

children 1-2 years old, the most highly exposed population was 91% of the cPAD. 

The chronic exposure assessment is conservative and is likely to overestimate risks based on a 

number of factors including, use of 100% crop treated assumptions for a number of crops for 

which data were unavailable, use of a conservative factor to account for the BF4 Conjugate, use 

of default processing factors, and use of drinking water exposure estimates for application of 

buprofezin to coffee, which is grown in limited areas the U.S. (e.g., Puerto Rico, Hawaii).

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 PAD. The PAD is equivalent to a point of departure (POD; e.g., 

no-observable-adverse-effect-level (NOAEL)) divided by the required uncertainty or safety 

factors. 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,” 6/21/2000, web link: 

http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf ; or see SOP 99.6 (8/20/99).

The most recent buprofezin dietary risk assessment was conducted by B. Daiss (DP# 365822, 

6/17/09).

II. Residue Information

A. Residues of Concern in Plants Commodities

The qualitative nature of buprofezin in plants is understood based on previously submitted 

lettuce, tomato, cotton, and lemon metabolism data. [Note: These data are all briefly 

summarized in Attachment 1 and includes a figure depicting the proposed pathway in lemon.] 

Buprofezin is metabolized via hydroxylation of the tert-butyl group to form an intermediate 

metabolite identified as free Metabolite BF4 (free Metabolite BF4 was not isolated in studies) 

which conjugates or degrades fairly rapidly via oxidation and cleavage to form Metabolite BF9, 

and ring-opening to form BF12. In minor routes, buprofezin may undergo opening of the 

thiadiazine ring to form Metabolite BF25, which may undergo oxidation to form Metabolite 

BF11; or free Metabolite BF4 may undergo opening of the thiadiazine ring and further oxidation 

to form Metabolite BF26. The BF4 Conjugate may only be released with more forcing acid 

hydrolysis procedures (conc. HCl/dioxane) resulting in a number of hydrolysis products of the 

procedure itself. In the lemon metabolism data these hydrolysis products of the study procedure 

were identified as BF9, BF12, Metabolite A (now identified as BF26) and Metabolite B. [Note: 

The current enforcement method incorporates only mild acid hydrolysis and is not expected to 

release any substantial portion of the BF4 Conjugate.]

Buprofezin was the major residue identified in the lettuce, cotton, and tomato metabolism 

studies. In the lemon metabolism study, almost all of the residues were in/on the peel (99% 

TRR) and consisted mainly of buprofezin which declined with longer PHIs (66% TRR at 14-day 

PHI and 18% TRR at 75-day PHI) and the BF4 Conjugate which increased with longer PHIs 

(identified predominately as one of its acid hydrolysis products, Metabolite A (now identified at 

BF26) at 6% TRR at 14-day PHI and 34% TRR at 75-day PHI). The BF4 Conjugate was only 

released after using more forcing acid hydrolysis (dioxane:conc. HCl) as a number of final

hydrolysis products of the study procedure. All other residues were <10% TRR, including BF9 

and BF12. Free BF4 was not isolated.
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 5 of 49

A grape processing study, which considered the potential for buprofezin to concentrate in 

processed grape commodities, also, considered the potential for BF9 and BF12 residues (i.e., 

those residues determined by data collection methods using mild acid hydrolysis) to concentrate 

in processed grape commodities. These data demonstrate the potential for residues of BF12 to 

concentrate to a greater degree than buprofezin. 

MARC met to discuss buprofezin on three occasions (3/28/00; 3/6/01; and 12/3/03) and, in 

addition to determining that buprofezin was the residue of concern for tolerance setting and a 

residue of concern for risk assessment in crops, also found that: (1) residues of concern in grape 

juice are buprofezin and BF12; (2) residues of BF9 and BF12 should be monitored in all future 

field trial and processing studies; (3) additional apple, grape, and orange processing data 

determining residues of the BF4 Conjugate should be submitted; in the absence of these data, the 

residues of concern for risk assessment purposes in crops with an interval greater than 

approximately 50 days from initial application to harvest should include the BF4 Conjugate; (4) 

the BF4 Conjugate should be estimated using the ratio of the BF4 Conjugate:buprofezin residues 

from the lemon metabolism study and the buprofezin residues from field trials. A 

recommendation for the numerical ratio of the BF4 Conjugate;buprofezin residues from the 

lemon metabolism study was not provided and left to the discretion of the buprofezin team which 

has chosen to express the ratio as a Factor for the BF4 Conjugate. [Note: The available data 

collection methods cannot determine the BF4 Conjugate which is released with more forcing 

acid hydrolysis procedures and identified in the available lemon metabolism data primarily as the 

hydrolysis products of the study procedure, including BF9, BF12, Metabolite A (now identified 

as BF26) and Metabolite B.]

A new lemon metabolism study has been submitted (MRID 48540804) which also demonstrates 

that most of the residues are in/on the peel (99% TRR) and consists mainly of buprofezin which 

declines with longer PHIs (47% TRR at 7-day PHI, 19% TRR at 35-day PHI, 9% TRR at 70-day 

PHI) and the BF4 Conjugate which increases with longer PHIs (identified predominately as one 

of its acid hydrolysis products, BF9 at 20% at 7-day PHI, 29% TRR at 35-day PHI, and 27% 

TRR at 70-day PHI). Confirming our earlier conclusions, these data indicate that over time the 

BF4 Conjugate reaches a level of significance when compared to levels of parent; however, that 

level of significance may occur earlier and possibly to a greater degree than indicated in the 

previously submitted lemon metabolism study which was considered by MARC. Qualitatively 

these data indicate that residues of the BF4 Conjugate should be considered a residue of concern 

in crops with PHIs much shorter than recommended by the MARC. RAB4 now finds that BF4 

Conjugate should be considered a residue of concern in crops with PHIs >7-days. [Note: In fact, 

previous risk assessments have considered the BF4 Conjugate a residue of concern at much 

shorter PHIs than recommended by the MARC.] However, given that residue levels were so low

in this new lemon metabolism study (buprofezin in/on peel at <0.10 ppm at 7- to 70-day PHI), 

these data are not considered as robust as the previously submitted lemon metabolism study 

(buprofezin in/on peel ≤0.551 ppm at 14- to 75-day PHI) for estimating residues of the BF4 

Conjugate quantitatively. Hence, in the absence of other evidence/circumstances precluding the 

need, the residues of concern in crops with a PHI greater than approximately 7 days are 

buprofezin and the BF4 Conjugate and the previously submitted lemon metabolism study will 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 6 of 49

continue to be the basis for estimating residues of the BF4 Conjugate.

RAB4 now find that, collectively, the available lettuce, tomato, and lemon metabolism data 

indicate that with relatively short PHIs (≤ 7-days) the major residue in/on fruits and vegetables is 

buprofezin. However, with longer PHIs (> 7-days) residue levels of the BF4 Conjugate, which is 

not released by the mild acid hydrolysis (1N HCl) incorporated into the available data collection 

methods, increase relative to the amount of parent present. Small amounts of metabolites 

identified as BF9, BF12, and BF26 may be found but should not reach levels of significance. 

BF9, BF12, and BF26 are probably the hydrolysis products of an intermediate metabolite 

identified as free BF4 which probably degrades fairly rapidly under mild acidic conditions. The 

BF4 Conjugate appears to be released only after using more forcing acid hydrolysis 

(dioxane:conc. HCl; 5:2; v/v; 16 hours at 50°C) as a number of final hydrolysis products of the 

study procedure, including BF9, BF12, Metabolite A (now identified as BF26, and Metabolite B. 

Most of the residues remain in/on crop surfaces but are not readily removed with simple rinsing 

with water. Residues that penetrate the surface may remain in the peel and over time will consist 

of significant levels of the BF4 Conjugate. Based on the results of the grape processing study 

which indicate that BF12 residues may concentrate to a greater degree than parent, default 

processing factors in DEEM should not be reduced based on buprofezin data alone. Table 1 is a 

summary of the decisions regarding residues of concern for buprofezin.

MARC Memos: D264546, T. Bloem, 4/20/00; D273214, T. Bloem, 3/13/01; TXR No. 0052261, T. Bloem, 12/10/03. 

1 Table updated with RAB4 decision concerning circumstances under which the BF4 Conjugate should be considered a residue 

of concern for the risk assessment and is based on information not available to the MARC. 

2 Residues of concern in rotational crops are buprofezin, BF9 and BF12. However, since there are no rotational crop tolerances, 

the BF9 and BF12 metabolites are not included in the dietary exposure analysis for rotational crops. 

B. Determination of the Factor for the BF4 Conjugate (metabolite not determined by data 

collection methods)

The MARC recommended that the BF4 Conjugate should be estimated using the ratio of the BF4 

Conjugate:buprofezin residues from the lemon metabolism data but did not offer a numerical 

estimate for the ratio. In previous dietary risk assessments, HED has expressed the ratio as a 

1.8x Factor for the BF4 Conjugate. HED continues to believe that the factor for the BF4 

Conjugate should be based on the previously submitted lemon metabolism data. A summary of 

these metabolism data is provided in Attachment 1.

Background for 1.8x Factor for the BF4 Conjugate: The previously submitted lemon metabolism 

study provided data for fruit treated at 0.89 lb ai/A/application twice at 75- and 14-days prior to 

harvest and fruit treated only once 75-days prior to harvest. Buprofezin (66% TRR, PHI=14 

days; 18% TRR, PHI=75 days) and the BF4 Conjugate which was identified predominately as 

the final acid hydrolysis product, Metabolite A (now identified as BF26; 5.7% TRR, PHI = 14 

days; 34% TRR, PHI = 75 days) were the major residues. All other identified residues were 

<10% TRR. Based on the ratio of Metabolite A:buprofezin, residues of the BF4 Conjugate were 

estimated at 0.09x and 1.8x the residues of buprofezin at 14-days and 75-days PHI, respectively. 

However, upon re-evaluation of the lemon metabolism data and the previous determination of 

the appropriate Factor for the BF4 Conjugate, all of the identified hydrolysis products of the 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 8 of 49

study procedure which are related to the BF4 Conjugate, which included BF9, BF12, Metabolite 

A (now identified as BF26), and Metabolite B, were not included in the calculation. Reevaluation of the appropriate factor (see Attachment 1 for details) indicates that, based on the 

lemon metabolism study data discussed above and assuming linearity, residues of the BF4 

Conjugate are expected to be significantly greater than buprofezin in/on crops by a factor of 1.8x 

at 40- to 50-days PHI. Given the uses under consideration, RAB4 finds no need to calculate a 

more conservative factor based on longer PHIs. [Note: Based on these data which are used for 

quantification, residues of the BF4 Conjugate are expected to be insignificant in/on crops at ≤7-

days PHI.] 

C. Application of Factor for BF4 Conjugate – Computation and Exclusions

An additional factor for the BF4 Conjugate (1.8x) based on the previously submitted lemon 

metabolism data was used for all raw agricultural commodities (RAC) and processed 

commodities to account for all residues of concern unless data/circumstances indicated that an 

additional factor for the BF4 Conjugate was not necessary. The additional factor for the BF4 

Conjugate (1.8x) was incorporated using a simple multiplier of 2.8 applied to the anticipated 

residue (AR) for buprofezin to calculate the total residues of buprofezin + the BF4 Conjugate as 

follows: 

AR Buprofezin x Multiplier (2.8) = (AR Buprofezin) + (AR Buprofezin x BF4 Conjugate Factor (1.8x))

Based on the available data, taken together, which indicate that the majority of the residue in/on 

plants ≤7-days after the last foliar treatment is primarily buprofezin, no additional factor for the 

BF4 Conjugate is needed for the anticipated residue (AR) estimates for the following raw 

agricultural commodities (RACs) or members of crop groups/subgroups which were based on 

tolerances/field trial data (FTD) reflecting PHIs ≤7-days: (1) Leafy Greens, Crop Subgroup 4A; 

(2) Leafy Petioles, Crop Subgroup 4B; (3) Brassica Head and Stem, Crop Subgroup 5A; (4) 

Leafy Brassica Greens and Turnip Greens, Crop Subgroup 5B; (5) Fruiting Vegetables, Crop 

Group 8; (6) Cucurbit Vegetables, Crop Group 9; (7) Citrus Fruits, Crop Group 10; (8) Low 

Growing Berry, Crop Subgroup 13-07G; (9) Coffee; (10) Papaya; (11) Mango; (12) Canistel; and 

(13) Mamey Sapote.

The need for an additional factor for the BF4 Conjugate for the AR estimates for RACs which 

are based on PDP monitoring data cannot be dismissed based on registered PHIs (i.e. the shortest 

permissible PHI which may or may not be typical Good Agricultural Practice (GAP)) since the 

time between application and harvest for the PDP monitoring samples is unknown and longer 

PHIs are expected to result in significant levels of the BF4 Conjugate. However, based on the 

lettuce metabolism data reflecting a 14-day PHI indicating that the majority of the total 

radioactive residue (TRR) was buprofezin (89% of the TRR), and given the relatively short 

growth season of spinach (seed to harvest 35 to 70 days), an additional factor for the BF4 

Conjugate is not deemed necessary for ARs used in the chronic analysis for spinach, head 

lettuce, and leaf lettuce which are based on spinach PDP monitoring data. 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 9 of 49

Also, based primarily on the available lemon metabolism data which demonstrated that the 

majority of the TRR remained in/on the peel (99% of the TRR), no additional factor for the BF4 

Conjugate is needed for the AR estimates for the RACs of bananas/plantains, tree nuts, and 

pomegranate whether they are based on FTD or PDP monitoring data. The majority of the 

buprofezin residues of concern are likely to be in/on the peels/skins/shells which are not 

consumed. 

Also, based on the available cotton metabolism data no additional factor for the BF4 Conjugate 

is needed for the AR estimates for the RACs of cotton.

D. Residues of BF9 and BF12 (metabolites which are determined by the data collection 

methods) in grape juice and other processed commodities

Given the potential for BF9 and BF12 to concentrate to a greater degree than buprofezin in 

processed commodities, default processing factors were retained, except for tomato paste and 

puree. Default processing factors for tomato paste (5.4x) and tomato puree (3.3x) were reduced 

to 1.2x based on tomato processing data (MRID 44576920; DP# 273252, T. Bloem, 3/20/01). 

Samples of tomato paste and puree were analyzed for residues of BF9 and BF12 which were 

determined to be <LOQ (<0.05 ppm) and deemed insignificant when compared to residues of the 

parent. 

E. Residues of Concern in Livestock Commodities

The MARC also previously reviewed ruminant and poultry metabolism and concluded 

(D273214, T. Bloem, 3/13/01) that due to the low TRR in eggs and tissue samples collected from 

the poultry metabolism study, the nature of the residue in poultry could not be determined and 

for the purposes of risk assessment the residues of concern in milk are parent and BF23 and in 

meat are parent and BF2. Table 1 above provides a summary of the residues of concern. 

The residues of concern in milk are buprofezin and BF23. Data from a feeding study in which 

dairy cows were dosed with buprofezin at dietary burden levels of 5 ppm, 16 ppm and 52 ppm 

(0.9x, 2.9x, and 9.3x the maximum theoretical daily burden (MTDB) for dairy cattle) were used to 

determine residue levels in milk for the acute dietary assessment. Residues of buprofezin (0.02 

ppm) and BF23 (0.01 ppm) were only determined in milk samples collected from the 9.3x dosing 

group. Based on these results, an estimate of 0.0032 ppm (0.03 ÷ 9.3) for the combined residues of 

buprofezin and BF23 in milk at 1x the MTDB was used for the acute dietary analysis. Based on 

the submitted data, which indicated a 5x concentration of residues into milk cream and fat and a 

Log Kow of 4.31, HED concluded that it is likely that residues will partition into milk fat. 

Therefore, a default 25x concentration factor was applied for milk fat yielding a residue of 0.08 

ppm which was used for the acute analysis. 

The residues of concern in ruminant tissues are buprofezin and BF2. Data from the feeding study 

in dairy cows (dosed at the equivalent of 0.7x, 2.1x, and 6.8x the beef cattle MTDB) were also 

used to determine residue levels of buprofezin and BF2 in liver, kidney, fat, and muscle for the 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 10 of 49

dietary assessment. Residues were <LOQ in kidney and muscle from all three dosing levels. 

Residues of buprofezin and BF2 were <LOQ in liver and fat collected from the 0.7x and 2.1x 

dosing groups and were 0.05 ppm and <0.05 ppm in liver and 0.12 ppm and <0.05 ppm in fat 

collected from the 6.8x dosing group. Based on these results, an estimate of 0.015 ppm (0.10 ÷ 

6.8) was used in the dietary analysis for the combined residues of buprofezin and BF2 in meat, 

kidney, and liver, and an estimate of 0.025 ppm (0.17 ÷ 6.8) was used for the combined residues of 

buprofezin and BF2 in fat and meat byproducts. Table 2 below provides a summary of the crop 

residue estimates used in the acute and chronic dietary analysis. 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 11 of 49

F. Established/Recommended Tolerances

Buprofezin is currently registered for application to numerous fruit and vegetable commodities. 

Tolerances for residues of buprofezin range from 0.02 - 80 ppm (40 CFR 180.511). Tolerances 

have also been established for residues of buprofezin in milk (0.01 ppm) and ruminant and hog 

fat (0.05 ppm), liver (0.05 ppm), meat (0.05 ppm) and meat byproducts (0.05 ppm). 

Under PP#1F7905, Nichino America, Inc. is proposing a new use for buprofezin on tree nuts 

(including pistachio). In conjunction with these uses, HED is recommending the tolerances

below for residues of buprofezin, including its metabolites and degradates. Compliance with the 

tolerance levels specified below is to be determined by measuring only the buprofezin.

Nut, tree group 14 ................................................................0.05 ppm

Pistachio...............................................................................0.05 ppm

Under PP#1E7908, Interregional Research Project Number 4 (IR-4) is proposing new or 

expanded uses for buprofezin on succulent beans; Brassica, leafy greens, crop subgroup 5B; 

turnip greens; fruiting vegetables, crop group 8-10; citrus fruit, crop group 10-10; pome fruit, 

crop group 11-10; persimmon; and tea (no U.S. registration). HED is not recommending in favor 

of the expanded use of buprofezin on citrus fruit to include the new members of crop group 10-

10. In conjunction with these uses, HED is recommending the tolerances below for residues of 

buprofezin, including its metabolites and degradates. Compliance with the tolerance levels 

specified below is to be determined by measuring only the buprofezin.

Bean, succulent ....................................................................0.02 ppm

Brassica, leafy greens, subgroup 5B ............................... 60 ppm

Turnip, greens....................................................................60 ppm

Vegetable, fruiting, group 8-10............................................2.0 ppm

Fruit, pome, group 11-10 (except pear and pear, oriental) ..3.0 ppm

Pear ......................................................................................6.0 ppm

Pear, oriental ........................................................................6.0 ppm

Persimmon ...........................................................................1.9 ppm

Tea......................................................................................20 ppm

G. Residues Used in the Acute Analysis

The acute analysis assumed the following: tolerance-level buprofezin residues or total buprofezin 

and BF4 Conjugate residues in plant commodities and 100% crop treated. The residues of concern 

in/on crops with a preharvest interval (PHI) of ≤7 days is buprofezin and in/on crops with a PHI >7

days are buprofezin and the BF4 Conjugate. Since there are no monitoring data for the BF4 

Conjugate, BF4 Conjugate residues were estimated, where needed, by multiplying the buprofezin 

tolerance level by 2.8x. [See discussion above concerning the determination and application of the 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 12 of 49

Factor for the BF4 Conjugate.] Given the potential for BF9 and BF12 to concentrate to a greater 

degree than buprofezin in processed commodities, DEEM default processing factors were retained 

for all commodities, except for tomato paste and puree which were reduced to 1.2x based on 

empirical data. The residues of concern in grape juice are buprofezin, the BF4 Conjugate, and 

BF12. Based on the submitted lemon metabolism data, which indicated that residues of concern 

are primarily found in/on the peel, the maximum theoretical concentration factor for peel was used 

to estimate total residues of concern in/on citrus peel. Total residues of concern in meat 

(buprofezin and BF2) and milk (buprofezin and BF23) were based on the feeding study data which 

were used to establish meat and milk tolerances for buprofezin. Based on the submitted data,

which indicated a 5x concentration of residues into milk cream and fat and a Log Kow of 4.31, a 

default 25x concentration factor was applied to milk fat. Table 2 is a summary of the crop residue 

estimates used in the acute analysis. 

 

H. Residues used in the Chronic Analysis

The chronic analysis assumed average field trial, average USDA Pesticide Data Program (PDP), or 

tolerance-level crop residues based on the available data. The residue(s) of concern in/on crops 

with a preharvest interval (PHI) of ≤7 days is buprofezin and in/on crops with a PHI >7 days are 

buprofezin and BF4 Conjugate. The residues of concern in grape juice are buprofezin, BF4 

Conjugate, and BF12. Since there are no monitoring data for BF4 Conjugate, BF4 Conjugate

residues were estimated, where needed, by multiplying the buprofezin anticipated residue (AR) 

level by 2.8x. [See discussion above concerning the determination and application of the Factor 

for the BF4 Conjugate.] Given the potential for BF9 and BF12 to concentrate to a greater degree 

than buprofezin in processed commodities, DEEM default processing factors were retained for all 

commodities, except for tomato paste and puree which were reduced to 1.2x based on empirical 

data. Based on the submitted lemon metabolism data, which indicated that residues of concern are 

primarily found in/on the peel, the maximum theoretical concentration factor for peel was used to 

estimate residues of concern in citrus peel. The chronic analysis used available screening-level 

percent crop treated estimates or projected percent crop treated estimates. If no %CT data was 

available 100% CT was assumed. Total residues of concern in meat (buprofezin and BF2) and 

milk (buprofezin and BF23) were based on the feeding study data which were used to establish 

meat and milk tolerances for residues of buprofezin. Based on the submitted data, which indicated 

a 5x concentration of residues into milk cream and fat and a Log Kow of 4.31, a default 25x 

concentration factor was applied to milk fat. Table 2 is a summary of the crop residue estimates 

used in the chronic analysis.

Note 2: There are available apple juice PDP monitoring data which found no detectable residues 

of buprofezin. However, these data would indicate a higher estimate for buprofezin in apple due

III. Water Data

Drinking water residues were incorporated directly into the acute and chronic dietary analyses 

(“water, direct, all sources” and “water, indirect, all sources”) and were provided by the 

Environmental Fate and Effects Division (EFED; DP#s 395217 and 393932, R. Parker, 4/5/12). 

EFED generated the surface water and ground water estimates using the Pesticide Root Zone 

Model 3 (PRZM3; ver. 3.12.2; 2-May-2005)/Exposure Analysis Modeling System (EXAMS; 

ver. 2.98.04.06; 25-Apr-2005) and Screening Concentration in Ground Water (SCIGROW; Tier 

1) models, respectively. For the purposes of assessing drinking water risk, estimated drinking 

water exposure concentrations (EDWCs) are based on the use with the highest potential 

exposure. Based on Tier II exposure modeling, past assessments have found the maximum 

exposure to be from the uses on coffee and citrus (DP# 360583, M. Corbin, 1/8/09) based on the 

Puerto Rico Coffee and Florida Citrus scenarios. The proposed new and expanded uses yield 

EDWCs below those previously determined. The coffee use yields the highest EDWCs to date. 

The EDWCs for coffee are based on a maximum seasonal application rate of 4 lb ai/acre.

Updated EDWCs are provided in Table 3.

IV. DEEM-FCID Program and Consumption Information

Buprofezin acute and chronic dietary exposure assessments were conducted using DEEMFCID (Ver. 2.03), which incorporates consumption data from USDA’s 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 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 24 of 49

respondents, HED 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 foodform (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 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 per-capita (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.

V. Results/Discussion

A screening level acute analysis was performed using DEEM-FCID to estimate dietary 

exposure. Acute analysis results are reported for the population subgroup females 13-49 years 

old. No acute endpoint was identified for the remaining population subgroups. The 95th

percentile acute food exposure estimate for females 13-49 years old is not of concern to HED 

(5% aPAD; see Table 5).

A refined chronic analysis was performed using DEEM-FCID to estimate dietary exposure. 

The results reported are for the general U.S. Population, all infants (<1 year old), children 1-2 

years old, children 3-5 years old, children 6-12 years old, youth 13-19 years old, females 13-49 

years old, adults 20-49 years old, and adults 50+ years old. The chronic food exposure estimates 

are also not of concern to HED (91% cPAD; children 1-2 years old were the most highly 

exposed population; see Table 6).

VI. Characterization of Inputs/Outputs

The acute analysis is conservative as tolerance-level residues were assumed for the majority of 

the commodities and 100% crop treated was assumed for all commodities. The chronic analysis 

was refined through the use of average field trial residues, percent crop treated data, and PDP 

data where available. While refined, the chronic analysis should still be considered conservative 

and likely to overestimate risk based on use of a number of conservative assumptions to estimate 

exposure. 

In the course of conducting a refined dietary exposure analysis, decisions are made regarding the 

residue data used in the analysis (e.g., field trials, monitoring data, etc.), refinements 

incorporated in the analysis (such as percent crop treated and processing factors), and a variety of 

other issues which may be chemical- or crop-specific. The following provides a discussion of 

the assumptions used in the buprofezin dietary analysis and the uncertainties associated with 

those assumptions.

Uncertainties

Residue Data and Assumptions

The acute analysis used tolerance level residues which were established based on field trial data. 

The chronic analysis assumed average field trial, average USDA Pesticide Data Program, or 

tolerance-level crop residues based on the available data. Data from feeding studies were used to 

establish meat and milk residues for the chronic analysis. PDP and field trial residues in 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

 Page 27 of 49

representative commodities were translated to the remaining commodities in the crop group 

according to HED SOP 2000.1. 

PDP data were used where available and appropriate i.e., in some cases available PDP data were 

not used for certain crops because the data were collected prior to or shortly after buprofezin was 

registered for use on those crops. PDP data from representative commodities were used to 

estimate residues for the chronic dietary assessment for pome fruits (Crop Group 11 – except 

crabapple, loquat and quince), banana/plantain, grape, grapefruit, lemon, lettuce (head and leaf), 

orange, peach, spinach, and strawberry commodities. PDP non-detects were assumed to be 1⁄2 

LOD.

Tolerance levels were used for succulent beans, citrus oil, tree nuts, cottonseed oil, tea, and most 

of the tropical fruits (excluding papaya, mango, canistel, black and mamey sapote, and star 

apple). Field trial data from representative commodities were used for the remaining 

commodities. Tolerances and field trial data estimates are based on quantifiable residues for all 

of these commodities. 

The inclusion of BF4 Conjugate as a residue of concern is based on a lemon metabolism study. 

The current acute and chronic assessments estimated total residues of concern, including BF4 

Conjugate, by applying a multiplier of 2.8x to the anticipated residue estimate for buprofezin. 

The use of a factor to account for BF4 Conjugate was used for all raw agricultural commodities 

and processed commodities unless data/circumstances indicated that an additional factor for the 

BF4 Conjugate was not necessary. The use of a factor to account for BF4 Conjugate should be 

considered a highly conservative assumption since most of the BF4 Conjugate is found on the 

peel and not in the pulp. 

Processing Factors

Given the potential for BF9 and BF12 to concentrate to a greater degree than buprofezin in 

processed commodities, DEEM default processing factors were retained for all commodities, 

except for tomato paste and puree which were reduced based on empirical data. Based on the 

submitted lemon metabolism data, which indicated that residues of concern are primarily found 

in/on the peel, the maximum theoretical concentration factor for peel (3.3x) was applied to 

residues in citrus peel. 

Adequacy of %CT data

Percent crop treated data were used when available for the chronic dietary analysis. Screening 

level or projected usage data were available for most crops. Screening level estimates may 

underpredict usage. The use of 100% crop treated assumptions for commodities for which %CT 

data were not available is a conservative assumption.

Drinking Water EDWCs

The proposed new use on coffee yields the highest EDWCs to date. Therefore the coffee 

EDWCs were used to estimate drinking water exposures for this assessment. Water is a 

significant contributor to the chronic dietary exposure and risk assessment as discussed below. 

Since coffee is grown in limited areas in the US (e.g., Hawaii, Puerto Rico) the risk contribution 

from EDWCs estimated for use of buprofezin on coffee is limited to those areas. 

Significant Risk Contributors ("Risk Drivers")

Based on a critical commodity analysis, the major contributors to the chronic analysis for 

children 1-2 years old (most highly exposed population subgroup) were the new use on Brassica 

(Cole) leafy vegetables, crop subgroup 5B - 28% cPAD; water - 28% cPAD; and stone fruit -

13% cPAD. 

VII. Conclusions

Based on a screening level acute dietary and drinking water analysis, the exposure estimate for 

females 13-49 years old is not of concern to HED (5% aPAD). No acute endpoint was identified 

for the remaining population subgroups. 

Based on a refined chronic dietary and drinking water analysis, the exposure estimates are not of

concern to HED for Children 1-2 years old, the most highly exposed population (91% cPAD). 

Exposure estimates for the general population are not of concern (< 100% cPAD). The chronic 

exposure assessment should be considered conservative and is likely to overestimate risks based 

on a number of factors including, use of 100% crop treated assumptions for a number of crops 

for which data was unavailable, use of a conservative factor to account for metabolites, use of 

default processing factors, and use of drinking water exposure estimates for application of 

buprofezin to coffee which is grown in limited areas in the U.S. (e.g., Puerto Rico, Hawaii).

Attachment 1: Metabolism Data Summaries

Metabolism of [14C]-Buprofezin in Lettuce (MRID 44394049; D261869, 4/24/00, T. Bloem): Lettuce plants were 

treated with [C14]-buprofezin twice at ~0.76 lbs/acre (2x the maximum single and seasonal rate; 12 day treatment 

interval). TRR in lettuce harvested 14 days after the final treatment was 51.79 ppm. The majority of the radioactive 

residues were either recovered through a surface rinse with ethanol (89% TRR) or extracted with acetonitrile and 

water (8% TRR). Hydrolysis of the extracted fiber (1.0% TRR) with acid and base released 0.63% and 0.14% of the 

TRR, respectively (0.2% TRR remaining bound). The majority of the TRR was identified as buprofezin (89% TRR) 

with minor amounts of BF 9 (0.19% TRR), BF 12 (0.46% TRR), and BF 26 (0.62%). Four unknown peaks were 

identified, the largest of which was 0.36 ppm (0.69% TRR). A total of 93% of the TRR was 

identified/characterized. 

Disposition and Metabolism of [14C]-Buprofezin in Tomato (MRID 44435903; D261869, 4/24/00, T. Bloem): 

Tomato plants were treated with 4 applications of [C14]-buprofezin at ~0.10 lbs ai/acre (0.4x and 0.5x the maximum 

single and seasonal rates; 14 day retreatment intervals). Tomatoes were harvested 1 hour after the first treatment 

and 1 hour, 1 day, 3 days, and 7 days after the 4th application. TRRs in/on tomato fruit generally decreased with 

increasing preharvest intervals (0.578 ppm 1 hour PHI; 0.342 ppm, 7-day PHI). Levels of radioactivity removed 

with ethanol (26-61% TRR) were considerably higher than with water (4-16% TRR). The mean level of residues 

removed by water or ethanol generally decreased with increasing PHI.

A second experiment involved individually treating the fruit of eight tomato plants at various stages of ripening with 

0.042 mg of [C14]-buprofezin (applied directly to the fruit surface with a syringe). A tomato fruit sample collected 7 

days after treatment was rinsed with ethanol (76% TRR) and the rinsed fruit (24% TRR) was homogenized with 

ethyl acetate (17% TRR). Chromatographic analysis of the ethanol wash and ethyl acetate extract indicated that 

90% of the TRR was buprofezin (3% unidentified; 7% unextracted material). A separate tomato fruit sample (0.353 

ppm) collected 7 days after treatment was washed with ethanol (45% TRR) and separated into peel (41% TRR) and 

pulp (13% TRR), demonstrating that the majority of the radioactive residue was on the surface or in the peel.

Metabolism of [C14]-Buprofezin in Cotton (MRID 44394048; PP# 7F04923; D261869, 4/24/00, T. Bloem): 

Cotton plants were treated with [C14]-buprofezin at 0.77 lbs ai/acre 97 and 139 days after planting (2x the maximum 

single and seasonal application rates). The mean TRR in cotton gin byproducts and seed harvested 27 days after the 

second application was 15.64 ppm and 0.37 ppm, respectively. The major residue in both cotton gin byproduct and 

seed was buprofezin (58.8% and 57.3% of the TRR, respectively). Other compounds identified in both cotton gin 

byproduct and seed included BF 9 (5.8% and 1.4%, respectively), BF 12 (5.7% and 1.5%, respectively), and BF 26 

(6.1% and 0.4%, respectively). The total identified/characterized residue in cotton gin byproduct and seed was 

79.7% and 75.7%, respectively (unidentified peaks were 7.5% TRR or less). Bound radioactivity accounted for 

8.2% and 9.6% of the TRR in cotton gin byproduct and seed, respectively. 

Metabolism of [C14]-Buprofezin in Lemon (MRIDs 44576908 and 44576907; D273252, 3/20/01 T. Bloem): 

Lemon trees grown in a greenhouse were treated with [C14]-buprofezin (phenyl-ring labeled; specific activity ~40 

μCi/mg; formulated as Applaud® 40SC) 75 and 14 days before harvest at ~0.89 lbs ai/acre (0.4x the maximum 

single and seasonal rate). [Note: The proposed metabolic pathway in lemon is provided in Figure I-A below.] The 

majority of the total radioactive residue (TRR; 0.940 ppm) was found in/on the peel (ethanol rinse - 65.2% TRR; 

peel - 34.6% TRR). Pulp contained 0.3% of the TRR and was not further analyzed. Peel was extracted with ACN, 

ACN/water, and water and the extracts were combined (33.3% TRR), reduced to the aqueous phase, and partitioned 

with ethyl acetate at acidic, neutral, and basic pH. The combined ethyl acetate fractions (organic soluble - 12.3% 

TRR) and the remaining aqueous fraction (aqueous soluble - 21.0% TRR) were hydrolyzed with conc. HCl/dioxane. 

[Note: While milder procedures using dilute acid and/or base are expected to provide more accurate assignments of 

metabolite structures released, procedures using concentrated acid are expected to release moieties as their final 

hydrolysis products which could have only a minor relationship to the Conjugated form of the radioactive portion.] 

The resulting hydrolysates were partitioned with ethyl acetate at unchanged pH, pH7, and pH 10. The various 

extracts were analyzed resulting in identification of buprofezin (66% TRR) and the hydrolysis products BF9 (6.0% 
Buprofezin (PC Code 275100) Dietary Exposure and Risk Assessment DP#s 400883 and 401716

TRR), BF12 (1.7% TRR), Metabolite A (5.7% TRR), and Metabolite B (3.6% TRR). The petitioner was able to 

demonstrate through LC/MS analysis that Metabolite A was similar to the principal hydrolysis product of BF4 

(BF26). Based on these data, the BF4 Conjugate should be estimated at 17% TRR by summing the hydrolysis 

products (BF9 (6.0% TRR) + BF12 (1.7% TRR) + Metabolite A (5.7% TRR) + Metabolite B (3.6% TRR)). Based 

on the ratio of BF4 Conjugate (17.0% TRR):buprofezin (66% TRR), residues of the BF4 Conjugate are expected to 

be 0.26x the residues of buprofezin at 14-days PHI.

 

The petitioner also presented data from lemon trees treated with [C14]-buprofezin (phenyl-ring labeled; specific 

activity ~40 μCi/mg; formulated as Applaud® 40SC) 75 days before harvest at ~0.89 lbs ai/acre (0.4x the maximum 

single application rate and 0.2x the maximum seasonal rate). The majority of the TRR (0.401 ppm) was found in/on 

the peel (ethanol rinse - 15.8% TRR; peel - 82.9% TRR). Pulp contained 1.2% of the TRR and was not further 

analyzed. The sample was carried through the same extraction procedures outlined above. The various extracts 

were analyzed resulting in identification of buprofezin (18.4% TRR) and the hydrolysis products BF9 (7.3% TRR), 

BF12 (8.1% TRR), Metabolite A (34.0% TRR), and Metabolite B (9.2% TRR). Based on these data, the BF4 

Conjugate should be estimated at 58.6% TRR by summing the hydrolysis products (BF9 (7.3% TRR) + BF12 (8.1% 

TRR) + Metabolite A (34.0% TRR) + Metabolite B (9.2% TRR)). Based on the ratio of BF4 Conjugate (58.6% 

TRR):buprofezin (18.4% TRR), residues of the BF4 Conjugate are expected to be 3.2x the residues of buprofezin at 

75-days PHI.

Based on the lemon metabolism study data discussed above and assuming linearity, residues of BF4 Conjugate are 

expected to be significantly greater than buprofezin by a factor of 1.8x at 40- to 50-days PHI. See Figure 1-B

below. Hence, for crops with a PHI of 40-days or less, a simple multiplier of 2.8 applied to the anticipated residue 

(AR) estimate for buprofezin will account for residues of buprofezin and the BF4 Conjugate by incorporating a 

factor for the BF4 Conjugate based on the available lemon metabolism data as follows: 

AR Buprofezin x Multiplier (2.8) = (AR Buprofezin) + (AR Buprofezin x Factor (1.8) for BF4 Conjugate)

SUMMARY

Following a Buprofezin New Use Team Meeting on October 18, 2011, BEAD was asked to 

determine whether it is appropriate for HED to use the average percent crop treated (PCT) values 

from the recent Screening Level Usage Analysis (SLUA) or from the percent crop treated for 

new uses (PCTn) documents that BEAD has provided over the past five years as inputs to HED’s 

revised chronic dietary exposure analysis. BEAD reviewed available PCTn and SLUA data 

provided to HED in the past, along with registration and tolerance information for the various 

uses to determine the appropriate source for the percent crop treated data. The results are 

summarized in the section below.

RECOMMENDED PCT and PCTn VALUES FOR BUPROFEZIN USES

BEAD has provided HED refined PCT data for 30 uses of buprofezin over the past 5 years, 

including PCTn values for 20 new uses based on the market leader approach. Using the 

buprofezin registration history provided by RD, the usage data from the recent SLUA and PCTn 

documents, and OPPIN data on crop registrations, BEAD determined the appropriate source of 

PCT values for each of the 30 uses based on the following (except for grapes, which are 

described below):

1. In cases where the use has been registered for less than 5 years, BEAD believes that the 

original PCTn values provided should be used for the refined chronic dietary exposure 

assessment 

2. In cases where the use has been registered for more than 5 years, BEAD believes the 

SLUA values provided should be used for the refined chronic dietary exposure 

assessment 

3. Grapes are an exception to these two cases largely due to the increased usage of 

buprofezin on wine grapes. In this case we believe the PCTn value of 15% should be 

used for the chronic dietary exposure. 

BEAD also considers whether the surveyed data are sufficiently robust to indicate whether the 

average is a good indicator of future use. 

Table 1 contains PCTn values provided previously for uses that BEAD recommends HED use 

for their newly refined risk assessment. These numbers remain valid and should be used for the 

refined risk assessment.

* PCT values are available on the buprofezin SLUA for apples, cabbage, cauliflower, and cherries; 

however, since less than 5 years of survey data are available, the original PCTn values should be used. 

Table 2 contains PCT values from the August 2011 SLUA for uses (except lettuce) that BEAD 

recommends HED use for their newly refined risk assessment. BEAD has sufficient data on the 

actual percent of these crops treated with buprofezin to determine the average PCT for these 

registered uses. 

BEAD also provided PCTn values for head lettuce (67%) and leaf lettuce (63%); however, these 

uses have been registered since 2001 per OPPIN and there’s very little reported usage of 

buprofezin on lettuce over the past 10 years. California DPR reports use of buprofezin in terms 

of pounds a.i. applied on head lettuce in 2004 (1 lb) and 2007 (20 lbs) and on leaf lettuce in 2006 

(4 lbs); however, California DPR PCT data for lettuce are not reliable due to differences in their 

pct methodology and reporting periods. There is no reported use of buprofezin on lettuce in 

USDA NASS or private market research surveys. As such, BEAD recommends using <1% PCT 

for both head and leaf lettuce.

* BEAD provided PCTn values previously for pumpkins, squash, and tomatoes; however, since these 

uses have five or more years of survey data, the SLUA values should be used.

** Lettuce was surveyed but there are no reports of buprofezin usage; BEAD recommends <1% PCT.

CONCLUSION

BEAD has considered the available PCT data for each of the 30 uses that HED used previously 

to refine their chronic dietary exposure analysis in light of the buprofezin registration history 

provided by RD, the usage data from the recent SLUA and PCTn documents, and OPPIN data on 

crop registrations and conclude that the PCTn and PCT values in Tables 1 and 2 are appropriate 

for use in the newly refined risk assessment.
