A. Purpose of the Meeting?
This 4-day meeting concerns several scientific issues undergoing consideration within the EPA/Office of Pesticide Programs (OPP). The four session topics to be addressed during the 4-day meeting are indicated as follows:
The first session will focus on assessing the potential allergenicity of non-digestible proteins expressed as plant-pesticides. The specific case in question concerns the Cry9C insecticidal protein derived from Bacillus thuringiensis and expressed in field corn. The Agency is asking questions on the use of amino acid homology, the brown Norway rat model for food allergenicity and other subjects with regards to the assessment for potential allergenicity.
The second session will address the decomposition module in the Dietary Exposure Evaluation Model (DEEM) software. In estimating dietary exposure to pesticides, the Agency uses several sources for monitoring data of pesticide residues in foods. These monitoring data, however, are in the form of pesticide residues on composited samples and do not directly represent concentrations of pesticide residues in single food items. For acute dietary exposure estimation, it is the residues in single items of produce that are of interest rather than “average” residues measured in composited samples. The decomposition module in the DEEM software uses a statistical procedure in order to “decomposite” composited monitoring data to estimate residues in single items. The purpose of this presentation is to describe the decomposition component of the software.
The second session will also include a presentation of the MaxLIP (Maximum Likelihood Imputation Procedure) Pesticide residue decompositing procedure and software. For acute dietary exposure estimation, it is the residues in single items of produce that are of interest rather than “average” residues measured in composited samples. The MaxLIP software uses a maximum likelihood estimation procedure in order to “decomposite” composited monitoring data to estimate residues in single items.
The third session will focus on the Dietary Exposure Evaluation Model (DEEM). A major component of assessing the risks of pesticide substances is the estimation of dietary exposure to pesticide residues in foods. The Agency currently uses the DEEM exposure assessment software in conducting its dietary exposure and risk assessment. The purpose of this session is to describe the components and methodologies used by the DEEM software.
The last session is to provide the FIFRA SAP with a progress report on the Agency's efforts to implement the drinking water component of the FQPA aggregate exposure assessment. Aggregate exposure is defined to encompass multiple potential sources of exposure to pesticides and includes exposure from pesticide residues in food, in drinking water and in the home. In order to combine the drinking water component with the population based distribution of pesticide residues on food items in a statistically rigorous manner, the data should be developed with the same general structure. In this way, the Monte Carlo procedure used for the risk assessment for food stuffs can be extended to the drinking water component.
The Agency will outline the basic steps envisioned in developing national, population-weighted distributions of pesticide residues in drinking water and aggregating them with distributions in food. These steps include development of distributions of pesticide drinking water concentration values across surface water/drinking water intake locations, consideration of the impact of treatment by a water utility, and development of methodologies to combine the adjusted distributions with the distribution of pesticide residues on food items. The presentation on development of distributions of drinking water concentrations will describe a process using measured data with a computer modeling/analysis overlay. The details of how the Agency will consider the effects of treatment will be largely addressed in a future FIFRA SAP meeting.
