摘 要：The U.S. Environmental Protection Agency (EPA) National Exposure Research Laboratory (NERL) is performing research in support of the Food Quality Protection Act (FQPA) of 1996, which requires that pesticide exposure assessments to be conducted for all potential sources, routes and pathways, not just dietary intake. The goal of the NERL program is to develop and evaluate protocols and methods for assessing children's aggregate and cumulative exposures to pesticides, and to collect data required to reduce the reliance on default assumptions in development of quantitative exposure assessments. This paper provides an overview of the framework and technical approach for the research program and descriptions of studies being performed to fill data gaps in the following areas: (1) Spatial and temporal distribution of pesticide residues indoors; (2) Pesticide use patterns indoors; (3) Dermal exposure; (4) Indirect ingestion exposure; (5) Microenvironments and macroactivity patterns of children; and (6) Children's exposure measurements protocols and methods.
