Executive Summary

Acute and chronic aggregate dietary (food and 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 analyses were conducted in support of a human-health risk assessment for the proposed Section 3 uses of fomesafen sodium (commonly called fomesafen) on cantaloupe, cucumber, pea (succulent), pumpkin, summer squash, winter squash, watermelon, soybean (succulent) and lima bean (succulent). This memorandum was reviewed by two peer reviewers of the DESAC, per DESAC SOP 2012.1. 

Acute and Chronic Dietary Exposure Assessment

The assumptions of these unrefined acute and chronic assessments were tolerance-level residues, 100% crop treated, and default DEEM processing factors.  Model-based estimated drinking water concentrations (EDWCs) from the Environmental Fate and Effects Division (EFED) were also included.

The dietary exposure analyses in this assessment result in dietary risk estimates for food and drinking water that are below the Agency's level of concern for both acute and chronic dietary exposures for all population subgroups. The acute exposure for food plus drinking water to the general U.S. population and all population subgroups was <1% of the acute population adjusted dose (aPAD) at the 95[th] percentile of exposure. The chronic exposure for food plus drinking water to the general U.S. population is 32% of the chronic population adjusted dose (cPAD).  The subgroup with the highest chronic exposure and risk estimate is infants.  For infants, the exposure for food plus drinking water was 0.001915 mg/kg/day, which represents 77% of the cPAD.

Cancer Dietary Exposure Assessment

The Cancer Assessment Review Committee (CARC) classified fomesafen as "Not likely to be carcinogenic to humans;" therefore, a cancer assessment was not performed.

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 that 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, 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 that 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 fomesafen was conducted on 10/12/10 (A. LaMay, D382064).


II.  Residue Information

Fomesafen sodium is a contact herbicide in the diphenylether chemical class and acts via inhibition of protoporphyrinogen oxidase (PPO).  It is used to control broadleaf and grass weeds, as well as postemergence weeds in legumes and other crops.

Tolerances for fomesafen residues are listed in 40 CFR §180.433.  Currently tolerances are established for fomesafen acid in field soybeans, dry beans, and snap (succulent) beans at 0.05 ppm and peppers (bell and non-bell), potatoes, tomatoes, and cotton gin by-products and cottonseed at 0.025 ppm. In the current petitions (2E8061, 3E8167), uses are proposed for fomesafen on cantaloupe, cucumber, pea (succulent), pumpkin, summer squash, winter squash, watermelon, soybean (succulent) and lima bean (succulent). HED is recommending for tolerance levels of 0.025 ppm on cantaloupe, cucumber, pea (succulent), pumpkin, summer squash, winter squash and watermelon and 0.05 ppm on soybean (succulent) and lima bean (succulent) (I. Encarnacion,  D407932). All crops with existing and proposed uses of fomesafen were considered in this assessment.

The residue of concern for plant commodities and drinking water is fomesafen.  The residues of concern in livestock commodities consists of fomesafen and its metabolites 5-(2-chloro-α,α,α-trifluoro-p-tolyloxy) anthranilic acid and 5-(2-chloro-α,α,α-trifluoro-p-tolyloxy)-N-methylsulfonylanthranilamide.  However, based on the submitted livestock metabolism studies, HED concluded that the proposed/registered uses of fomesafen result in a 40 CFR §180.6(a)(3) situation for livestock commodities; i.e., there is no reasonable expectation of finite residues in livestock commodities.

Tolerance-level residues and 100% crop treated were used for all commodities included in these assessments. Tolerance levels are based on non-detectable residues found in field trials (see Table 1 below).  The tomato and potato processing studies previously submitted were inadequate due to the lack of detectable residues in/on the raw commodity.  Therefore, default tomato paste, dried tomato, tomato juice, and tomato puree, and dried potato concentration factors were used for these processed commodities.

The USDA Pesticide Data Program (PDP) monitored pesticide residues in catfish in 2008, 2009, and 2010.  In general, pesticide residues would not be expected to be found in fish unless the pesticide bio accumulates or has an aquatic use.  To determine whether or not residues are present in fish, HED now routinely checks PDP monitoring data regardless of the pesticide's uses and physicochemical properties.  However, PDP did not analyze catfish samples for fomesafen.  As a result, residues in fish were not included in the assessment.

III.  Percent Crop Treated Information

The acute and chronic assessments were both based on the assumption that 100% of all commodities with registered or proposed uses of fomesafen will be treated.

IV.  Drinking Water Data

The drinking water residues used in the dietary risk assessment were provided by the EFED in the following memorandum: Revised Fomesafen Drinking Water Assessment to Include IR-4 Use on Lima Bean and Groundwater EDWCs Using a Tier-I PRZM-GW Model (D412599, H. Zhong, 6/24/12) and incorporated directly into this dietary assessment.  Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."   EFED recommended the Tier I PRZM-GW highest acute value of 51.8 μg/L and chronic value of 32.3 μg/L for ground water estimated drinking water concentrations (EDWCs).  These EDWCs were based on the highest proposed application rate for fomesafen (0.375 lb a.i./acre). The ground water EDWCs were higher than the surface water EDWCs, which were based on Tier-II PRZM/EXAM modeling, and were therefore selected for use in the fomesafen dietary assessment. 

The drinking water models and their descriptions are available at the EPA internet site: http://www.epa.gov/oppefed1/models/water/. 

V.  DEEM-FCID Program and Consumption Information

Fomesafen acute and chronic dietary exposure assessments were conducted using the DEEM-FCID, Version 3.16, which incorporates 2003-2008 consumption data from USDA's NHANES/WWEIA.  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 a chronic dietary exposure assessment, an estimate of the residue level in each food or food-form (e.g., orange or orange juice) on the food commodity residue list is multiplied by the average daily consumption estimate for that food/food form to produce a residue intake estimate.  The resulting residue intake estimate for each food/food form is summed with the residue intake estimates for all other food/food forms on the commodity residue list to arrive at the total average estimated exposure.  Exposure is expressed in mg/kg body weight/day and as a percent of the cPAD.  This procedure is performed for each population subgroup.

For an acute exposure assessment, 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 performed at all levels of refinement.  However, for deterministic assessments, any significant differences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

VI.  Toxicological Information

The acute dietary endpoint is based on decreased body weight and motor activity (horizontal and vertical activity and time in central quadrant) in males observed in the acute neurotoxicity study in rats. The chronic dietary endpoint is based on hyalinization of the liver in males in the chronic toxicity/ carcinogenicity study in rat. These endpoints are applicable to all populations including infants and children. The FQPA safety factor is reduced to 1X as there there is no evidence of increased susceptibility in developing and young animals, and there are no residual uncertainties concerning pre- or post-natal toxicity. The toxicity and exposure databases for fomesafen are complete.  

In accordance with the EPA Final Guidelines for Carcinogen Risk Assessment (March 29, 2005), the CARC classified fomesafen as "Not Likely to be Carcinogenic to Humans."  This decision was based on the weight-of-evidence which supports activation of peroxisome proliferator activated receptor alpha (PPARα) as the mode of action for fomesafen-induced hepatocarcinogenesis in mice.  The quantification of cancer risk is not required. 

 A summary of the endpoints and points of departure selected for dietary risk assessment may be found in Table 2 below.

VII.  Results/Discussion 

As stated above, for acute and chronic assessments, HED is concerned when dietary risk exceeds 100% of the PAD.  The DEEM-FCI analysis estimates the dietary exposure of the U.S. population and various population subgroups.  The dietary assessment results summarized 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 Exposure Analysis

All acute dietary (food and drinking water) risk estimates are below the level of concern for the general U.S. population and all population subgroups assessed.  The acute exposure for food plus drinking water to the general U.S. population and all population subgroups was <1% of the aPAD at the 95[th] percentile of exposure.

Results of Chronic Dietary Exposure Analysis

All chronic dietary (food and drinking water) risk estimates are below the level of concern for the general U.S. population and all population subgroups assessed.  The chronic dietary risk estimate for the general U.S. population is 32% of the cPAD. The population subgroup with the highest exposure is all infants (<1 year old) at 0.001915 mg/kg/day, which utilized 77% of the cPAD.

 VIII.  Characterization of Inputs/Outputs
 
HED has conducted a highly conservative, health protective assessment for the existing and proposed new uses of fomesafen sodium.  Tolerance-level residues on foods along with 100% crop treated were used in the acute and chronic dietary exposure assessments.  In addition, DEEM default processing factors were used.  Drinking water estimates were based on a conservative modeling approach. Various refinements could be made to the assessments; however, as there are no risk estimates of concern, no refinements were incorporated.

 IX.  Conclusions
 
 Unrefined acute and chronic dietary (food and drinking water) exposure assessments were performed for fomesafen sodium which assumed tolerance-level residues and 100% crop treated.  The dietary analyses for fomesafen resulted in dietary risk estimates that are below the Agency's level of concern for acute and chronic dietary exposures.  The acute exposure for food plus drinking water to the general U.S. population and all population subgroups was <1% of the aPAD at the 95[th] percentile of exposure. The chronic exposure for food plus drinking water to the general U.S. population is 32% of the cPAD.  The subgroup with the highest chronic exposure and risk estimate is infants (<1 year old) at 0.001915 mg/kg/day, which represents 77% of the cPAD.
 
 HED is confident that this dietary assessment does not underestimate risk to the general U.S. population or any population subgroup.
