Abstract:The Children's Total Exposure to Persistent Pesticides and Other Persistent Organic Pollutants (CTEPP) study was designed by the U.S. EPA to collect data on young children's exposures to pesticides and other pollutants in their everyday environments in support of the Food Quality Protection Act of 1996. Participants were recruited randomly from selected homes and day care centers in 12 North Carolina and Ohio counties. Monitoring was performed over a 48-h period at the children's homes and/or day care centers. Samples that were collected included diet, water, air, urine, dust, soil, and surface wipes. Analytical methods were developed for some of the pollutants (e.g. perfluorinated acids, cis-Permethrin, Chlorpyrifos, 3,5,6-Trichloro-2-pyridinol) in media such as house dust and food while the study was on-going. These included screening methods (i.e., immunoassays) and quantitative analytical techniques (i.e., LC/MS/MS and chiral separations). These methods represent a significant step forward in reducing uncertainties in assessing children's exposures to these pollutants in their everyday surroundings. This work was a collaborative effort with several divisions (Cincinnati, OH; Las Vegas, NV and Research Triangle Park, NC) located in the National Exposure Research Laboratory. A brief discussion on the methods that were developed will be presented.
