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 to support a human health risk assessment for the proposed Section 3 requests on artichoke and caneberry Subgroup 13-07A.  This memorandum was reviewed by two peer reviewers of the DESAC, per DESAC SOP 2012.1. 
     
Acute and Chronic Dietary (Food and Drinking Water) Exposure Results and Characterization

Acute and chronic dietary (food and drinking water) exposure assessments were conducted for the current uses, and proposed new uses on artichoke and caneberry Subgroup 13-07A.  The assumptions of the dietary assessments included tolerance-level residues for all commodities and 100 % crop treated (CT) for all crops.  DEEM version 7.81 default processing factors were assumed except for where tolerances were established for processed commodities or when processing studies showed no concentration.  Modeled estimated drinking water concentrations were included in the assessment

There was no indication of an adverse effect attributable to a single dose for the general U.S. population.  However, an acute reference dose (aRfD) was established for females 13-49 years old, and an acute dietary exposure assessment was only conducted for females 13-49 years old.   
The acute dietary exposure estimate at the 95[th] percentile is <1% of the acute population adjusted dose (aPAD) for females 13-49 years old.

The chronic dietary (food and drinking water) exposure to halosulfuron-methyl is below HED's level of concern (<100% of the chronic population adjusted dose (cPAD)) for the general U.S. population and all population subgroups.  The chronic dietary exposure estimates are 2.0% of the cPAD for the general U.S. population and 5.5% of the cPAD for children 1-2 year old, the most highly exposed population subgroup.

Cancer Dietary (Food and Drinking Water) Exposure Results and Characterization

Halosulfuron-methyl is classified as "not likely to be a human carcinogen;" therefore, quantification of human cancer risk is not required.

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, 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.  HED is generally concerned when estimated cancer risk exceeds one in one million.  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," 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 halosulfuron-methyl was conducted by Cassi Walls (D396459, 07/12/2012).

II.	Residue Information

The Interregional Research Project No. 4 (IR-4) has proposed new uses of halosulfuron-methyl on artichoke and caneberry Subgroup 13-07A.  Permanent tolerances are established under §180.479(a)(1) for residues of halosulfuron-methyl and its metabolites determined as 3-chloro-1-methyl-5-sulfamoylpyrazole-4-carboxylic acid, expressed as halosulfuron-methyl equivalents, at levels ranging from 0.05 ppm (milk, fat and meat) to 1.0 ppm (meat byproducts ) of cattle, goat, hog, horse, and sheep at 0.1 ppm.  Tolerances are established under §180.479(a)(2) for residues of halosulfuron-methyl in/on a variety of field, fruit, and vegetable crop commodities at levels ranging from 0.05 to 2.0 ppm.  

The Metabolism Committee has concluded that the residue of concern for tolerance enforcement and risk assessment in target plants and rotational plants is halosulfuron-methyl (G. J. Herndon, No DP#s, 9/16/1993 and 5/21/1996).  

HED previously has concluded that the residue of concern in ruminants is halosulfuron-methyl. However, because the approved enforcement method for livestock commodities quantifies the parent compound and metabolites containing the 3-CSA moiety by converting residues to 3-CSA, tolerances for residues of parent and its metabolites in livestock commodities are determined as 3-CSA, expressed in halosulfuron-methyl equivalents.  

The residue of concern in water is halosulfuron-methyl.  

Residue Data used for Acute and Chronic Assessments:

These acute and chronic assessments are unrefined assessments using tolerance-level residues and 100% CT for all commodities.  Additionally, DEEM version 7.81 default processing factors were assumed except for where tolerances were established for processed commodities or when processing studies showed no concentration.  Based on processing studies, the processing factors for tomato paste, tomato puree, potato flour and potato granules/flakes were reduced to 1.   

Table 1 is a summary of the HED recommended food tolerances resulting from the proposed uses (D405659, L. Cheng, 11/26/2012).

   Drinking Water Data (We didn't receive the water memo, but EFED communicated (email) that there is no change.  

The drinking water residues used in the acute dietary risk assessment were provided by EFED in the following memorandum: "Halosulfuron methyl Drinking Water Assessment for Additional Food/Feed Uses on Proso Millet, Pasture and Rangeland Grass Forage, Fodder and Hay (Crop Group 17)" (D394244, J. Meléndez, 5/15/2012) 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."  Since the application rates associated with the proposed new uses did not exceed the application rate on rice (0.125 lb ai/A), a new acute drinking water assessment was not required for the acute dietary assessment (personal communication via email from Jose Melendez to Meheret Neghussie, date).    

Monitoring data is not available for halosulfuron-methyl; therefore estimated drinking water concentrations (EDWCs) were derived from models.     

Acute Tier I EDWCs for halosulfuron-methyl were based on a maximum annual application rate of 0.125 lb ai/A for rice.  The two screening models, FIRST and Screening Concentrations in Ground Water (SCI-GROW), were used for estimating EDWCs of halosulfuron-methyl.  Estimates for halosulfuron-methyl in surface water based on the FIRST model for rice are 59.2 ppb for acute and chronic concentrations.  This value was used for the acute dietary assessment only.   HED notes that this drinking water value is considered to be highly conservative and reflects a calculated concentration of residue in a shallow farm pond based on the maximum application rate on the label.  HED considers this value appropriate as a screening level assessment for potential acute exposure and since the calculated concentration does not pose a risk of concern, further refinement is not required.  
  
The estimate for halosulfuron-methyl in groundwater based on the SCI-GROW model result is 0.065 ppb.  Table 2 summarizes the results.

Halosulfuron-methyl, like most other sulfonylurea herbicides, is extremely mobile with a median Koc of 104 g/mL and Kf (Freundlich partition) values ranging from 0.32 to 3.6 in four test soils.  Its persistence in soil and water appears to be highly variable.  Halosulfuron-methyl has the potential to leach to groundwater, and also presents concerns for transport to surface water by runoff. 

IV.	DEEM-FCID(TM) Program and Consumption Information

Halosulfuron-methyl 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 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.

V.  Toxicological Information

The risk assessment team confirmed endpoints that were previously selected and confirmed the reduction to 1X of the FQPA Safety Factor for all population subgroups (D358031, W. Phang, 06/30/2009).  

Toxicological endpoints for use in dietary exposure risk assessments are summarized in Table 3 below.

VI.	Results/Discussion

As stated above, for acute and chronic dietary 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 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.  

Results of Acute Dietary (Food and Drinking Water) Exposure Analysis    

The acute dietary (food and drinking water) exposure to halosulfuron-methyl is below HED's level of concern.  The acute dietary exposure estimate at the 95[th] percentile is <1% of the aPAD for females 13-49 years old, the only population subgroup of concern.

Results of Chronic Dietary (Food and Drinking Water) Exposure Analysis

The chronic dietary (food and drinking water) exposure to halosulfuron-methyl is below HED's level of concern for the general U.S. population and all population subgroups.  The chronic dietary exposure estimates are 2.0% of the cPAD for the general U.S. population and 5.5% of the cPAD for children 1-2 year olds, the most highly exposed population subgroup.

VII.	Characterization of Inputs/Outputs

The acute and chronic assessments are considered to be highly conservative and health protective.  The residue levels used in the assessments for all commodities were the established or recommended tolerance levels.  The assessments were conducted using the assumption that 100% of the crop was treated.  Default (DEEM 7.81) processing factors were used unless processing studies were available (tomato and potato) and modeled estimated drinking water concentrations were included in the assessments.  

These assessments could be refined, which would likely significantly decrease the estimated risk, with percent crop treated estimates, anticipated residues, or monitoring data.  Since risk estimates are well below HED's level of concern, a more highly refined analysis is not needed at this time.
 
 
 
 
 
VIII.	Conclusions

Acute and chronic dietary exposure assessments were conducted for the proposed uses on artichoke and caneberry subgroup 13-07A.  The analyses were unrefined assessments, using tolerances for all commodities, the assumption of 100% CT, default (DEEM 7.81) processing factors when appropriate, and modeled water numbers.  

 For both of the acute and chronic assessments, assessments for all populations of concern have risk estimates which are below HED's level of concern.  HED is confident that the acute and chronic assessments do not underestimate risk to the general U.S. population or any population subgroup.
