This study has two primary objectives: 1) characterization of geographic, temporal, age-related, and gender-related variability in total OP pesticide exposure in children; and 2) determination of the relative contributions of environmental sources to total OP pesticide body burden in children. The extensive environmental and biological sampling proposed in this study will allow further refinement in field study protocols, sampling strategies, analytical techniques, and data interpretation for investigations of this kind. Work under the first objective of this study is likely to provide useful information on variability of children's exposure to OP pesticides. The multi-pathway study design proposed as the second objective should allow attribution of exposure to specific sources for homes in which significant exposures are occurring. The longitudinal biomonitoring study will enroll families from the Chelan/Douglas County region of eastern Washington State and from the King/Snohomish County region of western Washington State, and is designed to extend for a full calendar year. The cross-sectional total exposure study will involve collection of samples to account for all exposure pathways (diet, air, dermal, housedust), as well as biological monitoring.
