Executive Summary Acute and chronic dietary risk assessments were conducted using the Dietary Exposure Evaluation Model ( DEEM FCID   , Version 2.03), which uses food consumption data from the USDA's Continuing Surveys of Food Intakes by Individuals ( CSFII) from 1994 1996 and 1998. The analyses were performed to support the reregistration eligibility decision  Phase I.

Assessments were conducted for food alone and food plus drinking water from surface water and ground water sources. It was assumed that all commodities were treated and that residues were Dicamba Dietary Exposure Assessment DP Barcode: D317702 PC Code: 029801 Page 2 of 46 at the established or reassessed tolerance level. Tolerances range from 0.2 for cattle fat to 25 ppm for cattle kidney. Drinking water concentrations were estimated from PRZM EXAMS modeling of surface water and ground water monitoring studies.

Estimated exposures to dicamba for all population sub groups are well below the level of concern. The most highly exposed subgroup for both acute and chronic exposure is children, aged 1 2. At the 95th percentile of exposure, acute exposures are at 5.4 and 7.6% of the acute Population Adjusted Dose ( aPAD) for food and food plus water, respectively. Chronic exposures are at 6.5 and 6.6% of the chronic Population Adjusted Dose ( cPAD) for food and food plus water, respectively for children aged 1 2. Using a screening level value for groundwater, the chronic exposure for this subgroup is slightly higher, at 6.8% of the cPAD. When considering acute exposure in food and water combined, the most highly exposed subgroup is infants with 11% of the aPAD consumed.

Actual exposure is likely to be considerably lower. These assessments assume all commodities are at tolerance levels, but residues in most field trials are lower. The assessments also assume all crops are treated, but a screening level usage analysis ( M. Kaul, 9/ 20/ 04) indicate that the percent crop treated for most commodities is less than 20 %.

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 Reference Dose ( RfD) divided by the special FQPA Safety Factor.

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 web site: " Available Information on Assessing Exposure from Pesticides, A User's Guide," 6/ 21/ 2000, web link: http:// www. epa. gov/ fedrgstr/ EPA PEST/ 2000/ July/ Day 12/ 6061. pdf ; or see SOP 99.6 ( 8/ 20/ 99).

The most recent dietary risk assessment for dicamba was conducted by Jennifer Tyler ( 11/ 26/ 01, DP Barcode D276549).

II. Residue Information Dicamba ( 2 methoxy 3,6 dichlorobenzoic acid) is a selective benzoic acid herbicide registered for the control of weeds prior to or before their emergence. Different forms of dicamba ( acid and salt) have registered uses on several food/ feed crops including asparagus, barley, corn ( field and Dicamba Dietary Exposure Assessment DP Barcode: D317702 PC Code: 029801 Page 3 of 46 pop), grasses grown in pasture and rangeland, oats, proso millet, rye, sorghum, soybeans, sugarcane, and wheat. Application rates range from 0.5 to 2.8 lb ae/ A.

The residues of concern in barley, corn, cotton, grasses, oat, proso millet, sorghum, sugarcane, and wheat are dicamba and its 3,6 dichloro 5 hydroxybenzoic acid ( 5 OH dicamba) metabolite; these are the residues currently regulated in 40 CFR § 180.227 ( a)( 1). In asparagus, the residues of concern are dicamba and its 3,6 dichloro 2 hydroxybenzoic acid metabolite [ 40 CFR § 180.227 ( a)( 2)]; the metabolite 3,6 dichloro 2 hydroxybenzoic acid is also referred to as 3,6 dichlorosalicylic acid ( DCSA). The residues of concern in/ on aspirated grain fractions and soybeans are dicamba, 5 OH dicamba, and DCSA [ 40 CFR § 180.227 ( a)( 3)]. Dicamba and the degradate DCSA are included in the drinking water assessment.

Residue Data used for Acute and Chronic Assessments Tolerance level residues and 100% crop treated were assumed for all crops in this assessment. If sufficient data were available to reassess tolerances, then the reassessed values were used. The established values were used for most commodities with the exception of the livestock commodities and sorghum ( C. Olinger, D317703, in review). All processing factors were assumed to be 1, though the available processing data suggest that residue concentrations are reduced upon processing. A summary of the residue data used may be found in Table 1. Dicamba Dietary Exposure Assessment DP Barcode: D317702 PC Code: 029801 Page 4 of 46 Table 1.

Table 2 below provides a summary of the model estimates for drinking water from surface water sources. Surface water estimates were used in acute and chronic food and water dietary exposure assessments; in addition, a chronic food and water analysis was conducted using the highest value found in the Pesticides in Ground Water Database [ Hoheisel et al. 1991], 40 µ g/ L ( personal communication, Ibrahim Abdel Saheb, 8/ 31/ 05). Note that this analysis was done for screening purposes only, and does not represent expected concentration of dicamba in drinking water from groundwater sources.

For a variety of technical, historical, and availability reasons, DEEMTM was the program generally used by EPA's Office of Pesticide Programs for conducting its dietary risk assessments. With the advent and current availability of a number of other exposure software programs, OPP, registrants, and other interested parties have available to them the option of selecting other peer reviewed exposure software in conducting risk assessments for pesticides. Dietary Exposure assessments may also be performed with other, similar programs, and if submitted, such results will be reviewed by EPA for acceptability and comparability to existing peer reviewed software being used by OPP.

DEEM FCID   Program and Consumption Information Dicamba acute and chronic dietary exposure assessments were conducted using the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database ( DEEMFCID   , 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, Dicamba Dietary Exposure Assessment DP Barcode: D317702 PC Code: 029801 Page 6 of 46 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.

For acute exposure assessments, 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 all tiers of analysis. However, for tiers 1 and 2, any significant differences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

IV. Toxicological Information The toxicological endpoints used in this assessment are presented in Table 3, and were selected by the dicamba team in meetings on August 2 and August 4, 2005. The special FQPA Safety Factor has been reduced to 1 as there are no residual concerns regarding susceptibility and underestimation of exposure.

V. 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 are reported in Table 4 for food alone and Table 5 for exposure to food and water 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 At the 95th percentile of exposure, considering food alone the most highly exposed subgroup is Children 1 2, with 5.4% of the aPAD consumed. When considering food and water the most highly exposed subgroup is infants, with 11% of the aPAD consumed at the 95th percentile of exposure.

Results of Chronic Dietary Exposure Analysis When considering food alone, or food and water ( surface water sources), the most highly exposed subgroup is Children 1 2, with 6.5% and 6.6% of the cPAD consumed, respectively.

VI. Characterization of Inputs/ Outputs Actual exposure is likely to be much lower as this assessment assumed all commodities for which dicamba is registered are treated and residues are at the tolerance level. Although additional data are needed for the reassessment of some tolerances, available data suggest that most tolerances will not need to be increased. A screening level usage analysis ( M. Kaul, 9/ 20/ 04) indicate that the percent crop treated for most commodities is less than 20 %.

VII. Conclusions HED has no residual concerns regarding exposure to dicamba in food and water. Assuming 100% crop treated and tolerance level residues, the most highly exposed sub group is children 1 2. At the 95th percentile of exposure, acute exposure is at 7.6% of the aPAD. Chronic exposure is at 6.6% of the cPAD from when drinking water is from surface water sources, and at 6.8% using a screening estimate from ground water sources. Most of the exposure is from food.
