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, which uses 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).  This assessment used dietary survey data conducted from 2003 to 2008.  The analyses were conducted in support of a human-health risk assessment for the proposed Section 3 use of propamocarb-HCl on lima beans.  This memorandum was reviewed by two peer reviewers of the DESAC, per DESAC SOP 2012.1.

Acute Dietary Exposure Assessment:  Unrefined acute dietary (food and drinking water) exposure assessments [using tolerance-level residues and assuming 100% crop treated (CT) for all registered and proposed commodities] were conducted for females 13-49 years old, and the general U.S. population and various population subgroups.  Exposure to drinking water was incorporated directly in the dietary assessment using the acute (peak) concentration for surface water generated by the PRZM-EXAMS.  This assessment indicates that the acute dietary exposure estimates are below HED's level of concern, <100% acute population-adjusted dose (aPAD), at the 95[th] exposure percentile for the general U.S. population and all other population subgroups.  The acute dietary exposure is estimated at 34% of the aPAD for females 13-49 years old, and 25% of the aPAD for the U.S. population.  The most highly exposed population subgroup is all infants (<1 year old) at 75% of the aPAD.  

Chronic Dietary Exposure Assessment:  An unrefined chronic dietary (food and drinking water) exposure assessment (using tolerance-level residues and assuming 100% CT for all registered and proposed commodities) was conducted for the general U.S. population and various population subgroups.  Exposure to drinking water was incorporated directly into the dietary assessment using the chronic (annual average) concentration for surface water generated by the PRZM-EXAMS model.  This assessment concludes that the chronic dietary exposure estimates are below HED's level of concern, <100% chronic population-adjusted dose (cPAD), for the general U.S. population and all population subgroups.  The chronic dietary exposure is estimated for the U.S. population at 31% of the cPAD, and the most highly exposed population subgroup, all infants (<1 years old), at 50% of the cPAD.  

Propamocarb is classified as "not likely to be carcinogenic to humans"; therefore, a cancer assessment is not germane to this petition.

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 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 propamocarb-HCl was conducted by J. Tyler (Memo, 20-FEB-2004; D297250).

II.  Residue Information

Residues of Concern:  The nature of propamocarb-HCl residues in potatoes, cucumbers, and spinach is adequately understood based on acceptable metabolism studies.  The residue of concern in these crops for tolerance and risk assessment purposes is the parent propamocarb only (Memo, J. Rowell, 03-MAY-2000; D264293).  The nature of the residue in ruminants is adequately understood based on acceptable metabolism and feeding studies on dairy cattle, which were submitted as propamocarb-HCl is currently registered for use on ruminant feed items.  The residues of concern in livestock for tolerance and risk assessment purposes are the parent propamocarb and the 2-hydroxy propamocarb and propamocarb glucuronide metabolites (Memos, J. Rowell, 03-MAY-2000, D264293; and J. Tyler, 10-MAR-2005; D304509).  No poultry metabolism study has been submitted.  Propamocarb-HCl is currently not registered for use on any poultry feed items.

Established Tolerances:  Tolerances are established for the residues of propamocarb-HCl under 40 CFR §180.499(a) in/on lettuce, leaf (90 ppm); lettuce, head (50 ppm); potato (0.06 ppm); tomato, paste (5.0 ppm); vegetable, cucurbit, group 9 (1.5 ppm); and vegetable, fruiting, group 8 (2.0 ppm).  An adequate ruminant feeding study has been submitted (Memo, J. Tyler, 10-MAR-2005; D304509).  The feeding study data with the estimated maximum dietary burdens indicate that tolerances for the combined residues of propamocarb-HCl and its metabolites 2-hydroxy propamocarb and propamocarb glucuronide should be established for milk at 0.03 ppm, and liver of cattle, horse, goat, hog, and sheep at 0.15 ppm.  These tolerances are currently not in 40 CFR §180.499, but were included in the acute and dietary exposure assessment.

Recommended Tolerances:  The available residue chemistry database supports the establishment of the permanent tolerance with a geographical restriction for residues in/on bean, lima, succulent at 2.0 ppm.

Processing Factors:  The results of previously submitted potato and tomato processing studies indicate that propamocarb-HCl does not concentrate in processed samples of potato chips, flakes, wet peel, or dry peel (Memo, J. Stokes 10/17/96; Barcode D228264), but does concentrate in tomato puree (1.3x) and tomato paste (3.1x).  As the established tolerance of 2.0 ppm for fruiting vegetables will adequately cover residues in tomato puree, a tolerance was not required for this processed commodity; however, a tolerance of 5.0 ppm for residues in tomato, paste was established.  As a result of the potato and tomato processing studies, DEEM-FCID default processing factors were set to 1 for white potatoes-dry; tomato, paste; and tomato, puree.  DEEM-FCID default processing factors were used for all other registered and proposed commodities.

III.  Percent Crop Treated Information

The acute and chronic dietary exposure assessments assumed 100% CT for all registered and proposed uses.

IV.  Drinking Water Data

The estimated drinking water concentrations (EDWCs) used in the acute and chronic dietary risk assessment were provided by the Environmental Fate and Effects Division (EFED) in the memorandum dated 11-DEC-2012 (Memo, M. Ruhman; D368070).  Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."  The surface water values (using PRZM/EXAMS) for the acute (peak) and chronic (annual average) EDWCs, based on the container-grown ornamental use pattern, are 8,762 ppb and 1,067 ppb, respectively.

V.  DEEM-FCID Program and Consumption Information

Propamocarb-HCl acute and chronic dietary exposure assessments were conducted using the DEEM-FCID, Version 3.16, which incorporates consumption data from USDA's NHANES/WWEIA.  This dietary survey was conducted from 2003 to 2008.  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+ 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.

VII.  Results/Discussion 

As stated above, for acute and chronic assessments, HED is concerned when dietary risk exceeds 100% of the PAD.  The DEEM-FCID 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 50-99 years.

Results of Acute Dietary (Food and Drinking Water) Exposure Analysis:  Separate unrefined (using tolerance-level residues and assuming 100% CT for all registered and proposed commodities), acute dietary exposure assessments were conducted for females 13-49 years old, and the general U.S. population and various population subgroups.  Drinking water was incorporated directly in the dietary assessments using the acute (peak) concentration for surface water generated by the PRZM/EXAMS model.  This assessment concludes that the acute dietary exposure estimates are below HED's level of concern (<100% aPAD) at the 95[th] exposure percentile for females 13-49 years old (34% of the aPAD), the general U.S. population (25% of the aPAD), and all other population subgroups.  The most highly exposed population subgroup is all infants (<1 year old), at 75% of the aPAD.

 Results of Chronic Dietary (Food and Drinking Water) Exposure Analysis:  An unrefined (using tolerance-level residues and assuming 100% CT for all registered and proposed commodities), chronic dietary exposure assessment was conducted for the general U.S. population and various population subgroups.  Drinking water was incorporated directly into the dietary assessment using the chronic (annual average) concentration for surface water generated by the PRZM/EXAMS model.  This assessment concludes that the chronic dietary exposure estimates are below HED's level of concern (<100% cPAD) for the general U.S. population (31% of the cPAD) and all population subgroups.  The most highly exposed population subgroup is all infants (<1 year old), at 50% of the aPAD.

 VIII.  Characterization of Inputs/Outputs
 
The acute and chronic dietary assessments were highly conservative, using tolerance-level residues, and 100% CT information for all registered and proposed uses.  DEEM(TM) default processing factors were set to one for white potatoes-dry, tomato, puree, and tomato, paste; default DEEM-FCID(TM) processing factors were used for all other registered and proposed processed commodities.  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 dietary exposure assessment indicates that the acute dietary exposure estimates are below HED's level of concern, <100% aPAD, at the 95[th] exposure percentile for the general U.S. population and all other population subgroups.  The most highly exposed population subgroup was all infants (<1 year old) at 74% of the aPAD.  An unrefined chronic dietary exposure assessment indicates that the chronic dietary exposure estimates are below HED's level of concern (<100% cPAD) for the general U.S. population and all population subgroups.  The most highly exposed population subgroup was all infants (<1 year old) at 50% of the cPAD.  The acute and chronic assessments were highly conservative, using several upper-end assumptions.  Additional refinements, such as inclusion of ARs and %CT data could be made in order to refine the future assessments.  HED is confident that the assessments do not underestimate risk to the general U.S. population or any population subgroup.
