Impact/Purpose:

1. To identify those pesticides, pathways, and activities that represent the highest potential exposures to children;

2. To determine the factors that influence pesticide exposures to children;

3. To develop methods for measuring multimedia exposures to children, including methods that account for important activities that take place in home, school, and day care settings;

4. To generate data on multimedia pesticide concentrations, pesticide biomarkers, and exposure factors that can be used as inputs to aggregate exposure models for children.

Description:

In support of the Food Quality Protection Act of 1996, research under this task is designed to identify those pesticides, pathways, and activities that represent the highest potential exposures to children and to determine the factors that influence these exposures. The research will be used to develop methods, data, and models for evaluating aggregate exposure to pesticides and toxic chemicals. This research will focus on high-level, short-term exposure resulting from recent pesticide applications. Studies have been initiated in four areas: pesticide use patterns; distribution of pesticide residues in non-occupational environments; dermal and non-dietary exposure assessments; and dietary exposure assessments. These studies were completed in FY'02. Results of the studies have been used to develop a draft protocol for measuring children's exposures to pesticides and persistent organic pollutants. Sample analysis, data processing, data analysis, and reporting will be completed in FY '03. The outputs from these studies will provide critical data needed to develop methods for assessing aggregate exposure, to provide inputs for exposure models, to design future research to answer additional exposure issues, and to reduce uncertainties in exposure assessments for children. Results of the studies have been used to develop the study design for a large longitudinal field study of children's exposure to pesticides and persistent organic pollutants that is being performed under Task No. 7040.
