The current dietary assessment updates the most recent dietary assessment for 2,4-

dichlorophenoxyacetic acid (2,4-D) (Memo, T. Jimerson, D315512, 4118/05) and incorporates 

recently revised toxicological FQP A/uncertainty factors, points of departure, the new version of 

DEEM, and updated drinking water numbers for 2,4-D. This update is done in support of 

proposed new uses of2,4-D choline on 2,4-D tolerant field com and soybean. 

Executive Summary 

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

conducted using the Dietary Exposure Evaluation Model software with the Food Commodity 

Intake Database (DEEM-FCID) Version 3.16. This software uses 2003-2008 food consumption 

data from the U.S. Department of Agriculture's (USDA's) National Health and Nutrition 

Examination Survey, What We Eat in America, (NHANES/WWEIA). The current assessment is 

being conducted in support of proposed new uses of2,4-D choline on 2,4-D tolerant field com 

Page 1 of22 
2,4-D Dietary Exposure and Risk Assessment DP #: D413003 

and soybean. This assessment includes the proposed uses and all existing uses of 2,4 D. This 

memorandum was reviewed by two peer reviewers of the DESAC per DESAC SOP 2012. 1. 

The dietary analyses incorporated the drinking water estimates provided by Environmental Fate 

and Effects Division (EFED). The estimated drinking water concentrations (EDWCs) were 

estimated using the Pesticide Root Zone Model/Exposure Analysis Modeling System 

(PRZMJEXAMS) models for surface water and Screening Concentration In GROund Water 

model (SCI-GROW) for ground water. For ground water, the maximum concentration detected 

from monitoring data was 15 Jlg/L. For surface water, the 1-in-10 year acute (peak) and annual 

average concentrations are 136 and 23 Jlg/L, respectively (0403774 and 404562, F. Khan, 

10/2/20 12). EFED indicated that the estimated drinking water exposure for the acute assessment 

should be 136 ppb, the 1 in 10 year annual peak exposure based on the MS corn scenario. The 

chronic assessment should use the 1 in 10 year annual mean value of 23 ppb (email 

communication between Faruque K.han/EFED and Alexandra LaMay/HED, 10/03/12). 

The acute analysis assumed 100% crop treated (CT) for all commodities and tolerance-level 

exposure values for all commodities except for soybean. The highest average field trial (HAFT) 

value for residues of 2,4-dichlorophenol (2,4-DCP) and Yz LOD value for residue of parent 2,4-D 

was used for soybean (see description of residues of concern in Section II). Empirical and 

default processing factors were used as appropriate. The resulting acute food plus drinking water 

risk estimates are not of concern to HED [:S1 00% acute population-adjusted dose (aPAD)] at the 

95th percentile of the exposure distribution for all population subgroups of interest. The resulting 

acute risk estimate for children 1 to 2 years old, the subgroup with the greatest exposure, was 

14% of the aP AD at the 95th percentile of the exposure. 

The chronic dietary analysis was also unrefined, making use of the following: tolerance-level 

exposure values for all commodities except soybean (2,4-DCP HAFT residue was used for 

soybean), and 100 %CT information for all commodities, including field corn and soybean. 

Empirical and default processing factors were used as appropriate. The resulting chronic risk 

estimates are not of concern to HED. The most highly exposed population was children 1 to 2 

years old, utilizing 15% of the chronic PAD ( cP AD). 

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% ofthe 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/fednzstr/EPA-PEST/2000/July/Day-12/606l .pdf; or see SOP 99.6 (8/20/99). 

The most recent dietary risk assessment for 2,4-D was conducted by Toiya Jimerson (4/ 18/05, 

DP Number 315512).

II. Residue Information

Residues of Concern: HED’s Metabolism Assessment Review Committee (MARC) determined 

that the residue of toxicological concern to be included in crop and livestock tolerances and in 

dietary risk assessments (food and water) is 2,4-D, both free and conjugated, determined as the

acid (Memo, T. Jimerson, 10/13/04). 

In the risk assessments for 2,4-D-tolerant field corn and soybean (D400085, D. Drew, 7/11/13 

and D394981, A. LaMay, 10/27/11), it was determined that the metabolite 2,4-DCP also be 

included as a residue of concern for dietary risk assessment purposes for 2,4-D tolerant field corn 

and soybean as there are greater amounts of 2,4-DCP found in resistant crop compared to nonresistant crop. Since 2,4-DCP shows a similar toxicity profile to 2,4-D, comparing 2,4-DCP 

residues to 2,4-D endpoints would be protective for risk assessment purposes. 

Concerning transgenic field corn, as the combined residues of 2,4-D and 2,4-DCP found in 

transgenic field corn food items are less than the tolerances of parent only found in nontransgenic field corn, using field corn tolerance-level values for 2,4-D in the acute and chronic 

dietary analyses are protective of residues of 2,4-D and 2,4-DCP in transgenic field corn. 

Concerning transgenic soybean, the combined 2,4-D and 2,4-DCP residues were used for the 

acute and chronic dietary analyses as the combined residues found in tolerant soybean were 

greater than the tolerance of parent only for soybean. Residue levels of parent 2,4-D in/on 

soybean were non-detectable, thus estimated 2,4-D residues (at 1⁄2 LOD of 0.003 ppm, or 0.0015 

ppm) were added to the 2,4-DCP highest average field trial residue (HAFT is 0.047 ppm) to be 

used in the acute and chronic dietary analyses. Please refer to D400085 (D. Drew, 7/11/13) for 

more information.

Also, as the combined residues of 2,4-D and 2,4-DCP found in transgenic corn feed items are 

lower than those residues expected in other crop feed commodities, the addition of corn 

feedstuffs to the livestock diet would not increase the dietary burden. The existing livestock 

commodity tolerances are adequate to cover the use on feedstuffs of herbicide-tolerant field corn. 

A livestock feeding/grazing restriction for the soybean use is proposed; therefore, the current 

tolerances for residues of 2,4-D on soybean feedstuffs are not being reevaluated at this time.

Established/Recommended Tolerances: 2,4-D tolerances have been established in numerous 

plant commodities, crop groups, processed products, livestock commodities, fish, and shellfish at 

40 CFR §180.142. No new or revised tolerances are required to support the proposed new use 

on 2,4-D tolerant field corn and soybean (D400085, D. Drew, 7/11/13 and D394981, A. LaMay, 

10/27/11).

Residues Used in the Acute and Chronic Analyses: 

Tolerance-level residues were used as exposure values for all commodities in the acute 

assessment with the exception of soybean. The 2,4-DCP HAFT residue for transgenic soybean 

was used in the assessment. It was assumed that 100% of all crops had been treated. Note that 

this acute dietary analysis has changed from the previous dietary assessment (T. Jimerson, 

D315512, 4/18/05) in several ways: (1) use of tolerance-level residues instead of HAFT for 

citrus, (2) use of tolerances-level residues instead of average field trial residues for potato, (3)

inclusion of soybean residue values (HAFT value of 2,4-DCP and 1⁄2 LOD value for 2,4-D 
2,4-D Dietary Exposure and Risk Assessment DP #: D413003

_____________________________________________________________________________________________

combined residue for transgenic soybean), (4) use of tolerance-level residues for all livestock 

commodities, including milk, (5) inclusion of all food items for crop groups for which tolerances 

have been set (previously certain crops were excluded; see D280885, J. Tyler, 2002 for more 

information), (6) inclusion of default processing factors, and (7) inclusion of the drinking water 

estimates provided by EFED. This acute dietary exposure assessment is considered to be 

unrefined.

In the chronic dietary assessment, tolerance-level exposure values were used for all commodities 

except soybean. Concerning soybeans, the HAFT field trial residue of metabolite 2,4-DCP was 

used. It was assumed that 100% of all crops had been treated. Note that this chronic dietary 

analysis has changed from the previous dietary assessment in several ways: (1) inclusion of 

tolerance-level residues for all plant and animal commodities, including milk, (2) inclusion of 

herbicide-tolerant crop residue values, (3) use of 100% CT for all commodities, (4) inclusion of 

all food items for crop groups for which tolerances have been set, (5) inclusion of default 

processing factors, and (6) inclusion of the highest modeled surface water concentration for 

drinking water. This chronic dietary assessment is considered to be unrefined.

The DEEM 7.81 default concentration factors were used for applicable commodities, as 

appropriate.

To further refine the 2,4-D dietary exposure and risk estimates, HED could use %CT, anticipated 

residues, or monitoring data, where available, in the acute and chronic dietary exposure 

assessment.

III. Percent Crop Treated

Percent crop treated (%CT) data were not applied to the acute and chronic assessments; 100% 

CT was assumed for all commodities, including field corn and soybean, in both analyses. 

IV. Estimated Drinking Water Concentrations

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 EFED 

(D403774 and 404562, F. Khan, 10/2/2012). The EDWCs were estimated for ground water 

using the Screening Concentration in Ground Water (SCIGROW) model and for surface water 

using the Pesticide Root Zone Model (PRZM)/ Exposure Analysis Modeling System (EXAMS)

for 2,4-D. Monitoring data are also available.

EDWCs of 136 ppb and 23 ppb were used in the acute and chronic analyses, respectively.

2,4-D Dietary Exposure and Risk Assessment DP #: D413003

_____________________________________________________________________________________________ 

Page 5 of 22

2,4-D acute and chronic dietary exposure and risk assessments were conducted using DEEMFCID

(Ver. 3.16), which incorporates consumption data from USDA’s NHANES/WWEIA 

(2003-2008 data). The 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. However, for acute 

exposure assessment, consumption data are retained as individual consumption events. Based on 

analysis of the 2003-2008 WWEIA 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 50-99

years old.

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 analyses. 

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.

VII. Results/Discussion

Acute and chronic analyses were performed using DEEM-FCID (ver. 3.16) which estimates the 

dietary exposure of the U.S. population and various population subgroups. 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 50-99 years old.

The resulting acute food plus drinking water risk estimates are not of concern to HED (≤100% 

aPAD) at the 95th percentile of the exposure distribution for all population subgroups of interest. 

The resulting acute risk estimate for children 1 to 2 years old, the subgroup with the greatest 

exposure, was 14% of the aPAD at the 95th percentile of the exposure. The resulting chronic 

food plus drinking water risk estimates are not of concern to HED. The most highly exposed 

population was children 1 to 2 years old utilizing 15% of the cPAD. See Table 3 below for a 

summary of the results of the dietary assessment.

VIII. Characterization of Inputs/Outputs

The acute and chronic analyses assumed tolerance-level residues and 100% CT. To further 

refine the 2,4-D dietary exposure and risk estimates, %CT, anticipated residues, or monitoring 

data could be used in the acute and chronic dietary exposure assessments.

IX. Conclusions

The acute and chronic exposure and risk assessments were conducted using DEEM-FCID, ver. 

3.16. DEEM-FCID incorporates food consumption data from the NHANES/WWEIA (2003-

2008 data). 

The EDWCs were estimated for ground water using the SCI-GROW model and for surface water 

using PRZM/EXAMS. For ground water, the maximum concentration from monitoring data is 

15 μg/L. For surface water, the 1-in-10 year acute (peak) and annual average concentrations are 

136 and 23 μg/L, respectively. EDWCs of 136 ppb and 23 were used in the acute and chronic

analyses, respectively. 

The acute analysis assumed tolerance-level residues (except soybeans) and 100% CT. The acute 

analysis also incorporated the drinking water estimates provided by EFED. Empirical and 

default processing factors were used as appropriate. The resulting acute food plus drinking water 

risk estimates are not of concern to HED (≤100% aPAD) at the 95th percentile of the exposure 

distribution for all population subgroups of interest. The resulting acute risk estimate for 

children 1 to 2 years old (the subgroup with the greatest exposure) was 14% of the aPAD at the 

95th percentile of the exposure. 

The chronic analyses assumed tolerance-level residues (except soybeans) and 100% CT for all 

commodities. The chronic analysis also incorporated the drinking water estimates provided by 

EFED. Empirical and default processing factors were used as appropriate. The resulting chronic

risk estimates are not of concern to HED. The most highly exposed population was all children 1 

to 2 years old utilizing 15% of the cPAD. 

Both acute and chronic dietary analyses are unrefined and conservative.
