THOMAS, K. W., Y. HU, AND J. RAYMER. EVALUATION OF EXPOSURE MEASUREMENT METHODS AND APPROACHES FOR THE NATIONAL CHILDREN'S STUDY. Presented at NCS Pilot Study Meeting, Research Triangle Park, NC, December 03, 2004.
Impact/Purpose:
The primary goal of the AHS Pesticide Exposure Study (AHS/PES) is to measure exposure to applied pesticides for a subset of the cohort of private pesticide applicators and to provide data to evaluate exposure algorithms developed for exposure classification in the study cohort.
Description:
Several hypotheses have been proposed for the National Children's Study to examine the role of environmental exposures to chemical pollutants in health outcomes including asthma and impaired neurobehaviorial or neurocognitive function. To address these hypotheses, it will be necessary to assess exposures to a range of chemical pollutants at different life stages through the use of survey tools and biological and environmental measurement methods. The purpose of this work was to survey the literature to obtain and synthesize existing information about personal and environmental measurement methods and approaches, exposure questionnaire and diary methods, and to provide exposure data from pervious human exposure studies that are most relevant to the National Children's Study. This work also examined the relative strengths and weaknesses of existing methodology for chemical exposure measurement in a longitudinal study of children.
