Executive Summary

A chronic aggregate dietary (food and drinking water) exposure and risk assessment was 

conducted for the herbicide, rimsulfuron, using the Dietary Exposure Evaluation Model, DEEMFCIDTM, Version 2.03, which uses food consumption data from the U.S. Department of 

Agriculture’s Continuing Surveys of Food Intakes by Individuals (CSFII). The surveys were 

taken from 1994-1996 and included a supplemental children’s survey taken in 1998. The 

analysis was performed to support Section 3 registration on caneberry, bushberry, and chicory. 

An acute dietary assessment was not performed, as a toxicological endpoint attributable to a 

single dose has not been identified for rimsulfuron. Rimsulfuron is classified as “not likely” to 

be carcinogenic; therefore, a cancer assessment was not performed. 

The unrefined chronic assessment is based on the assumption that rimsulfuron residues are 

present at tolerance levels in all commodities for which tolerances have been established and that 

100% of those crops are treated. DEEMTM Version 7.81 default processing factors were applied 

to all processed commodities for which they were available. Drinking water was incorporated 

directly into the dietary assessment using the estimated drinking water concentration (EDWC) 

for surface water generated by the Tier 1 FQPA Index Reservoir Screening Tool (FIRST) Model. 

The resulting chronic dietary exposure estimates for food and water combined are well below 

HED’s level of concern for the general U.S. population and all population subgroups. Using the 

DEEM-FCID software, dietary exposure is estimated at 0.000428 mg/kg/day for the U.S. 

population (<1% of the chronic population adjusted dose (cPAD)) and 0.001063 mg/kg/day 

(<1% of the cPAD) for children 1 to 2 years old, the population subgroup with the highest 

estimated chronic dietary exposure to rimsulfuron. 

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 the 

point of departure (PoD; e.g. NOAEL, LOAEL, etc.) 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 website: “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).

II. Residue Information

Residues of Concern: The nature of the residue of rimsulfuron in plants and livestock has been 

adequately delineated based on metabolism studies conducted with rimsulfuron in field corn, 

potatoes, tomatoes, lactating goats, and laying hens. The metabolic pathways were found to be 

similar in plants and livestock. The major route of rimsulfuron metabolism/degradation involves 

sulfonylurea bridge contraction, with sulfonylurea bridge cleavage as a minor metabolic route. 

Based on the results of the studies, HED concluded that the residue of concern in plant and 

livestock commodities is rimsulfuron only (Memo, D360852, D. Rate, 8/13/2009, and MARC 

report, 2/11/98). 

Tolerances: Permanent tolerances have been established under 40 CFR §180.478(a) for residues 

of rimsulfuron at 0.01 ppm for citrus fruit, pome fruit, stone fruit, grapes, tree nuts, and 

pistachios; 0.05 ppm for tomatoes, 0.09 ppm for almond hulls, and 0.1 ppm for potatoes and field 

corn grain, forage, and stover. 

DuPont Corporation has proposed tolerances for residues of rimsulfuron in connection with uses 

on caneberry, blueberry, and chicory. HED has reviewed residue data submitted for caneberry 

and blueberry to support these uses and concluded that the tolerances given in Table 1 are 

appropriate (E. Holman, D356812, Sept. 2011). The chicory residue data and requested 

tolerance will be reviewed under the forthcoming review (D391764). 

Table 1. Rimsulfuron Recommended Tolerances 

Crop Commodity Recommended Tolerance (ppm) 

Caneberry, subgroup 13-07A 0.01 

Bushberry, subgroup 13-07B 0.01 

Chicory, roots 0.01 

Chicory, tops 0.01 

Residue Data used for the Chronic Assessment: The unrefined chronic dietary assessment is 

based on the assumption that rimsulfuron residues are present at tolerance levels in all 

commodities for which tolerances have been established and that 100% of those crops are 

treated. DEEMTM Version 7.81 default processing factors were applied to all processed 

commodities for which they were available. In the processing study for soybean oil, residues did 

not concentrate. Therefore, the processing factor was left at 1.0. For the commodities currently 

under review, there are no associated processed commodities in which residues are expected to 

concentrate. 

III. Drinking Water Data 

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

Environmental Fate and Effects Division (EFED, Memo, J. Melendez, D358869, 1/23/2009).

PC Code: 129009 

____________________________________________________________________________________________

Water residues were incorporated directly into the DEEM-FCID assessment under the food 

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

The residue of concern in drinking water is parent rimsulfuron only (HED MARC decision 

memo; 03/29/1994). EFED estimated residues of rimsulfuron in surface water and groundwater 

using the FIRST and SCIGROW (Screening Concentrations in Groundwater) models, 

respectively. The models and their descriptions are available at the EPA internet site: 

http://www.epa.gov/oppefed1/models/water/. The maximum estimated drinking water 

concentrations (EDWCs) are presented below in Table 2. 

Table 2. Maximum Rimsulfuron EDWCs in Surface and Ground Water 

Maximum Surface Water EDWC (ppb) Maximum Ground Water 

Acute Value Chronic/Cancer Value Acute/Chronic EDWC (ppb) 

5.596 0.120 0.016 

The chronic surface water EDWC was higher than the groundwater EDWC; therefore, the 

surface water value of 0.120 ppb was used in the chronic dietary assessment. The acute surface 

water value is not relevant to this dietary assessment, as a toxic effect attributable to a single 

dose has not been identified for rimsulfuron. 

IV. DEEM-FCIDTM Program and Consumption Information

A rimsulfuron chronic dietary exposure assessment was 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 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.

Cancer (oral, 

dermal, inhalation) 

Classification: 

Rimsulfuron is classified as a “not likely “human carcinogen. 

Point of Departure (PoD) = A data point or an estimated point that is derived from observed dose-response data and 

used to mark the beginning of extrapolation to determine risk associated with lower environmentally relevant human 

exposures. NOAEL = no observed adverse effect level. LOAEL = lowest observed adverse effect level. UF = 

uncertainty factor. UFA = extrapolation from animal to human (interspecies). UFH = potential variation in 

sensitivity among members of the human population (intraspecies). FQPA SF = FQPA Safety Factor. PAD = 

population adjusted dose (a = acute, c = chronic). 

The FQPA Safety Factor has been reduced to 1x for all population subgroups, as there are no 

residual uncertainties, and there is no evidence of increased pre- and/or post-natal susceptibility 

to rimsulfuron. There is no evidence of neurotoxicity in the database, and a developmental 

neurotoxicity (DNT) study has not been required. 

VI. Results/Discussion 

As stated above, for chronic assessments, HED is concerned when dietary risk exceeds 100% of 

the cPAD. The DEEM-FCIDTM analyses estimate the dietary exposure of the U.S. population 

and various population subgroups. The results reported in Table 3 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.

Rimsulfuron chronic dietary (food + water) exposure estimates using the DEEM-FCIDTM 

software are well below HED’s level of concern for the U.S. population and each of the 

population subgroups. Dietary exposure was estimated to be 0.000428 mg/kg/day for the U.S. 

population (<1% of the cPAD) and 0.001063 mg/kg/day (<1% of the cPAD) for the most highly 

exposed population subgroup (children, 1-2 years old). The estimated exposures and risks from 

residues of rimsulfuron in food and water are summarized in Table 4.

The population subgroup with the highest estimated chronic dietary (food + drinking water) exposure and risk is 

indicated by bold text. 

VII. Characterization of Inputs/Outputs

These chronic dietary exposure and risk estimates are highly conservative. They are based on 

the assumption that 100% of crops with tolerances are treated with rimsulfuron, and that residues 

in foods “as eaten” are present at tolerance levels. In addition, drinking water exposure estimates 

are screening level estimates generated by the Tier 1 FIRST Model. 

Dietary exposure estimates could be refined through the use of anticipated residues, percent crop 

treated data, and/or refined estimated drinking water concentrations. However, as estimated 

exposures and risks using conservative assumptions are well below HED’s level of concern, such 

refinement is not warranted. 

VIII. Conclusions

This unrefined chronic dietary exposure analysis using DEEM-FCIDTM indicates that chronic 

dietary exposure to rimsulfuron from food and drinking water is well below HED’s level of
