Executive Summary

Acute and chronic aggregate dietary (food and drinking water) exposure, and risk assessments were conducted for pendimethalin 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). These analyses were conducted in support of human health risk assessment for the proposed establishing new crop subgroups based on the tolerance of existing individual commodities; existing crop conversions and expansions; section 3 new use on hop, dried cones.  This memorandum was reviewed by two peer reviewers of the DESAC as per DESAC standard operating procedures (SOP) 2012.1. 

Unrefined acute and chronic dietary exposure assessments were conducted using tolerance-level residues for agricultural commodities, 100% crop treated, DEEM(R) default or empirical processing factors, and point estimates for potential drinking water residues (NY Grape scenario) that produced the highest estimated drinking water concentrations (EDWCs). 

Acute Dietary Exposure Assessment
The acute dietary risk estimate for the highest exposed population subgroup, all infants is 1.7% of the acute population adjusted dose (aPAD) and for the general U. S. population is <1.0% of the aPAD at the 95[th] percentile.  HED is concerned when estimated dietary risk exceeds 100%.  There are no acute dietary risk of concern.

Chronic Dietary Exposure Assessment
The chronic dietary risk estimate for the highest exposed population subgroup, children 1-2 years old is 1.7% of the chronic population adjusted dose (cPAD) and for the general U. S. population is <1.0% of the cPAD.  HED is concerned when estimated dietary risk exceeds 100%.  There are no chronic dietary risk of concern.
 
Cancer Dietary Exposure Assessment
Pendimethalin is categorized as "Group C, possible human carcinogen." Quantification of risk using a non-linear approach; i.e., RfD/PAD, will adequately account for all chronic toxicity, including carcinogenicity, that could result from exposure to pendimethalin. 

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 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 pendimethalin was conducted by Y. Barnes (05/02/2012, DP Number: D401100).

II. Residue Information

Pendimethalin (N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenenamine) is a selective herbicide used for controlling annual grass and broadleaf weeds. It is a meristematic inhibitor that interferes with the plant's cellular division of mitosis and is generally applied early in the growing season as a pre-emergent and early post-emergent herbicide. The agricultural uses of pendimethalin have been proposed for the aqueous capsule suspension formulation of the end-use product Prowl[(R)] H2O (38.7 % a.i.; EPA Registration Number: 241-418), a 3.8 lbs. a.i./gallon liquid formulation.  Prowl [(R)] H2O can be applied via ground and/or aerial application methods. The residues of concern in plant commodities, for tolerance enforcement and risk assessment purposes is pendimethalin and its 3, 5-dinitrobenzyl alcohol metabolite (DP# 329627, W. Drew, 07/12/2006).  The assessment assumed 100% crop treated.    

Currently, tolerances are established for the herbicide pendimethalin under 40 CFR: §180.361 for newly proposed subgroups based on existing tolerance for individual representative commodities: Low Growing Berry Subgroups 13-07G (0.1 ppm), Onion, bulb subgroup 3-07A (0.1 ppm), Onion, green subgroup 3-07B (0.2 ppm), and Sunflower Subgroup 20B (0.1 ppm); Crop Group conversions and expansions based on established crop group tolerance for Citrus Fruit Group 10 (0.1 ppm), Pome Fruit Group 11 (0.1 ppm), Stone Fruit Group 12 (0.1 ppm), and Fruiting Vegetable Group 8 (0.1 ppm).  A new tolerance is proposed and recommended for Hop, dried cones (0.1 ppm).

Empirical processing factors obtained from processing data were utilized for processed commodities, when available and adequate residues; in grape processed commodities are assumed to be the same as the raw commodity. DEEM(TM) 7.81 processing factors were used for the processed commodities, with the exception of grapes, wheat, and citrus (DP Number: 334173, 08/02/2007).  

Tolerance-level residue values for pendimethalin were incorporated for all RACs, current and proposed. 

The USDA Pesticide Data Program (PDP) monitored pesticide residues in catfish over the time period of 2008: 552 samples - maximum residue = 18 ppb, 2009: 543 samples  -  maximum residue = 13 ppb, and 2010: 384 samples  -  maximum residue = 74 ppb. Over this 3-year period, PDP analyzed ~ 1479 samples of catfish for pendimethalin residues.  Detects were found in 42 samples of catfish.  As a result, these residues in catfish (fin fish) were included in the dietary risk assessment. The chronic dietary input for catfish was an average (0.035 ppm) of PDP residue data for pendimethalin and the acute dietary input for catfish used the single highest (0.074 ppm) value PDP residue data for pendimethalin. Tolerance for crayfish established at 0.05 ppm, (D332750 and 345270 C. Olinger, 03/31/2008)

III. Percent Crop Treated Information

Percent crop treated information was not incorporated into this assessment. 

IV. Drinking Water Data

The estimated drinking water residues used in the dietary risk assessment were provided by the Environmental Fate and Effects Division (EFED) in the following memorandum: "Tier II Estimated Surface Drinking Water Concentrations and Estimated Ground Water Concentration (EDWCs) for Pendimethalin for Use in Human Health Risk Assessment," D334061, J. Breithaupt, 05/08/2007, this DWA were to be used as expressed in the referenced email. (Email: Ibrahim Abdel-Saheb 06/18/2014) and incorporated directly into the dietary assessment. Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."

These 1 in 10 year annual peak (acute), 1 in 10 year annual mean (non-cancer chronic), and 36- year annual mean concentrations (cancer chronic) were derived from modeling pendimethalin using the New York grape scenario.  Since no degradates have been identified in the metabolism studies at significant (>10 % of applied) levels, no degradates of pendimethalin were modeled in this 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

Pendimethalin 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

Pendimethalin has a low acute toxicity via the oral, dermal, or inhalation route. It is not a dermal or eye irritant; and is not a dermal sensitizer. The thyroid is a target organ for pendimethalin. Thyroid toxicity in chronic and subchronic rat and mouse studies was manifested as alterations in thyroid hormones (decreased total T4, and T3, increased percent of free T4 and T3), increased thyroid weight, and microscopic thyroid lesions (including increased thyroid follicular cell height, follicular cell hyperplasia, as well as follicular cell adenomas).

Thyroid tumors were observed in both male and female rats in a chronic/carcinogenicity study. There were no tumors observed in the carcinogenicity study in mice. The Health Effects Division (HED) Cancer Peer Review Committee classified pendimethalin (03/18/1992 and re-affirmed 11/01/99) as a "Group C", possible human carcinogen based on a statistically significant increased trend and pair-wise comparison between the high dose group and controls for thyroid follicular cell adenomas in male and female rats. The Committee also recommended a non-quantitative approach (i.e., non-linear, RfD approach) since mode of action studies are available that demonstrate that the thyroid tumors are due to a thyroid-pituitary imbalance, and also since pendimethalin was shown to be non-mutagenic in mammalian somatic cells and germ cells. The chronic risk assessment is considered to be protective of any cancer effects; therefore, a separate quantitative cancer aggregate risk assessment is not required.

The points of departure and uncertainty factors/safety factors used for dietary risk assessment are summarized in Table 2.

VII. Results/Discussion 

As stated above, for the acute and the chronic (food and water) dietary assessments, HED is concerned when dietary risk exceeds 100%.  The DEEM-FCID analyses estimate the dietary exposure and risk of the general U.S. population and selected population subgroups.  The chronic results are reported 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, females 13  -  49 years and adults 50-99 years. The acute results are reported for the females 13-49 years old.

Acute Dietary Exposure Assessment
The acute dietary risk estimate for the highest exposed population subgroup, all infants at (0.017009 mg/kg/day) is 1.7% of the acute population adjusted dose (aPAD) and for the general U. S. population at (0.007311 mg/kg/day) is <1.0% of the aPAD at the 95[th] percentile. HED is concerned when estimated dietary risk exceeds 100%.  There are no acute dietary risks of concern. 

Chronic Dietary Exposure Assessment
The chronic dietary risk estimate for the highest exposed population subgroup, children 1-2 years old at (0.005043 mg/kg/day) is 1.7% of the chronic population adjusted dose (cPAD) and for the general U. S. population at (0.001592 mg/kg/day) is <1.0% of the cPAD. HED is concerned when estimated dietary risk exceeds 100%.  There are no chronic dietary risks of concern. 

Cancer Dietary Exposure Assessment
Pendimethalin is categorized as "Group C, possible human carcinogen." Quantification of risk using a non-linear approach; i.e., RfD/PAD, will adequately account for all chronic toxicity, including carcinogenicity, that could result from exposure to pendimethalin. 

A summary of the acute and chronic dietary results are reported in Table 3.

 VIII. Characterization of Inputs/Outputs
 
 These acute and chronic dietary exposure and risk analyses represent a screening level conservative assessment using tolerance level residues, DEEM(TM) 7.81 processing factors or empirical processing factors were used when available.  Further refinements are not needed at this time since the reported dietary risk results are not of concern.
 
 
 IX. Conclusions
 
As stated above, for acute and chronic (food and water) dietary assessments, HED is concerned when estimated dietary risk exceeds 100% of the PAD. These analyses demonstrate that the registered uses for pendimethalin will not result in dietary risks of concern.  HED is confident that the acute and the chronic assessments do not underestimate exposures and risks.
