Executive Summary

Acute and chronic aggregate dietary (food and drinking water) exposure and risk assessments 

were conducted using the Dietary Exposure Evaluation Model DEEM-FCIDTM, Version 2.03 

which use food consumption data from the U.S. Department of Agriculture’s Continuing Surveys 
Diquat (PC Code: 032201) Dietary Exposure and Risk Assessment DP Number: D369480

of Food Intakes by Individuals (CSFII) from 1994-1996 and 1998. The analyses were performed 

to support a Section 18 use of diquat on canola.

Acute Dietary (Food and Drinking Water) Exposure Results and Characterization

The acute dietary assessment assumes 100% crop treated and tolerance-level residues of diquat 

for all foods with registered uses. Default processing factors from DEEM v.7.81 were used in 

the analysis. For drinking water, the acute assessment uses the Office of Water’s Maximum 

Contaminant Level (MCL; 0.02 ppm), which is considered to be a worst-case estimate. Acute 

dietary risk estimates are below HED’s level of concern (i.e., < 100% of the acute populationadjusted dose; aPAD) for all population subgroups.

Chronic Dietary (Food and Drinking Water) Exposure Results and Characterization

The chronic assessment is based on tolerance-level residues and 100% crop treated for crops 

with direct diquat uses. For crops with tolerances to cover irrigation with diquat-treated water, 

anticipated residue levels from irrigation trials are used in conjunction with estimates of % of 

crops irrigated. For fish, average residues are assumed. Default processing factors from DEEM 

v.7.81 were used in the analysis. For drinking water, the chronic assessment uses the Office of 

Water’s Maximum Contaminant Level (MCL; 0.02 ppm), which is considered to be a worst-case 

estimate. Chronic dietary risk estimates are below HED’s level of concern (i.e., < 100% of the 

acute population-adjusted dose; aPAD) for all population subgroups.

Diquat has been classified as not carcinogenic to humans; therefore, cancer risk is not a concern 

for this compound.

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.

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 dietary risk assessment for diquat was conducted by B. Daiss (11 December 

2001, D277766).

II. Residue Information

Diquat is registered for a number of uses, including direct application to crops as well as 

application to water (as an aquatic herbicide) and subsequent irrigation of crops with treated 

water. Tolerances for diquat range from 0.02 ppm for a number of commodities to 20 ppm for 

shellfish (40 CFR 180.226). A separate listing [Part (a)(5)] is provided for potato chips and dried 

flakes. The residue of concern for tolerance enforcement and risk assessment is the diquat 

cation. For the acute assessment, tolerance-level residues and an assumption of 100% crop 

treated have been used for all entries in the analysis. The chronic assessment is more refined and 

includes average residue levels from irrigated crop trials (MRID 00031836) and estimates of % 

crop irrigated (D369862, B. Phillips, 21 October 2009) for those crops with irrigated crop 

tolerances [40 CFR 180.226(a)(2)(i)]. For fish and shellfish, average residue levels, calculated 

from MRID 40427601, are being used rather than tolerance-level residues. With the exception of 

potato chips and dried potato flakes, which have their own tolerances, default processing factors 

from DEEM v.7.81 are used in both analyses to account for potential concentration of diquat 

during the formation of processed food forms (particularly juices and dried foods). For the 

requested Section 18 use of diquat on canola, a tolerance value of 1.0 ppm is being 

recommended by HED and is used for these assessments.

Full listings of the residue input assumptions are provided in Attachments 1 (acute) and 2

(chronic) and are summarized in Table 1.

* Irrigation data are from MRID 00031836. Refined dietary burden takes into account anticipated residues in feed 

items as well as % irrigation data. Livestock residue estimates are the tolerance modified by the ratio of the 

previous and refined dietary burden values.

III. Drinking Water Data

As per the 2002 Tier 1 drinking water assessment1, the MCL of 20 ppb (0.02 ppm) was assumed 

for both the acute and chronic assessments. Modeled estimates of diquat in drinking water are 

available. The FQPA Index Reservoir Screening Tool (FIRST) model was used to estimate

environmental concentrations in drinking water from surface water contaminated by terrestrial 

uses of diquat. The following scenarios were modeled: trees/vines/small fruits/vegetables 

(maximum use rate of 1 lb a.i./A, single application, 87 PCA); potatoes (0.5 lb a.i./A, 2 

applications, 14 day application interval, 87 Percent Cropped Area); and alfalfa/clover/non-crop 

(0.5 lb a.i./A, 1 application, single application, 87 PCA) . The surface water estimated 

environmental concentrations (EECs) generated by FIRST range from 6.3- 13.2 ppb (ug/L) for 

peak exposure and 0.2-0.4 ppb for annual average exposure. The model and its description are 

available at the EPA internet site: http://www.epa.gov/oppefed1/models/water/. 

IV. DEEM-FCIDTM Program and Consumption Information

Diquat acute and chronic dietary exposure assessments were conducted using the Dietary

Exposure Evaluation Model software with the Food Commodity Intake Database DEEMFCIDTM,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 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.

D281199)
Diquat (PC Code: 032201) Dietary Exposure and Risk Assessment DP Number: D369480

Page 5 of 23

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. Toxicological Information

The toxicity data base for diquat dibromide is adequate for the selection of doses and endpoints 

for use in risk assessment. The doses and endpoints selected for dietary risk assessment are 

summarized in Table 2.

VI. Results/Discussion 

As stated above, for acute and chronic assessments, HED is concerned when dietary risk exceeds 

100% of the PAD. The DEEM-FCIDTM analyses estimate the dietary exposure of the U.S. 

population and various population subgroups. The results reported in Table 2 are for the general 

U.S. Population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-19, 

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

Results of Acute Dietary (Food + Drinking Water) Exposure Analysis

The results of the acute dietary exposure analysis are reported in Table 3, below. Risk estimates 

at the 95th percentile of exposure are well below HED’s level of concern. The 95th percentile of 

exposure is appropriate for evaluation given the conservative nature of the assessment. A full 

summary of the acute assessment results is included in Attachment 3.

Results of Chronic Dietary (Food + Drinking Water) Exposure Analyses

The results of the chronic dietary exposure analyses are also summarized in Table 3. The refined 

dietary risk estimates are below HED’s level of concern for all population subgroups. 

Attachment 4 provides the full output of the chronic dietary analysis.

The highest exposure/risk estimate for each duration is bolded.

VII. Characterization of Inputs/Outputs

The use of tolerance-level residues for food and MCL-level residues in water, results in high-end 

acute dietary exposure estimates; especially when combined with the assumption of 100% crop 

treated for all commodities. The chronic assessment incorporates refinements for residue 

estimates and percent of crops “treated” for irrigated crops only (and as those refinements impact 

livestock residue estimates). Given that tolerance-level residues are still used for a number of 

commodities and information regarding % of crops irrigated is not available for all crops, the 

chronic dietary exposure and risk estimates are fairly conservative with regard to protecting 

human health.
