Wilson, N K., J. C. Chuang, C. Lyu, AND M K. Morgan. PAH CONCENTRATIONS IN MULTIPLE MEDIA AT THE HOMES AND CHILD DAY CARE CENTERS OF 130 NORTH CAROLINA CHILDREN. Presented at 18th International Symposium on Polycyclic Aromatic Compounds, Cincinnati, OH, September 9-13, 2001.
Impact/Purpose:
The overall objectives of CTEPP were to measure the aggregate exposures of approximately 260 preschool children and their adult caregivers to low levels of a suite of pesticides and organic pollutants that the children may encounter in their everyday environments, and to apportion the routes of exposure and estimate the relative contributions of each route.
Description:
In the late summer of 2000 and the early spring of 2001, in the USEPA-sponsored program, "Children's Total Exposures to Persistent Pesticides and Other Persistent Organic Pollutants" (CTEPP), we conducted a field pilot study of the potential exposures of 130 North Carolina preschool children and their primary caregivers to persistent pollutants in their everyday environments, both at home and at their day care centers. Over a 48-hr period for each participant, we collected samples of indoor and outdoor air, house and classroom dust, play area soil, children's hand surface wipes, urine, and diet. The samples were analyzed for 20 polycyclic aromatic hydrocarbons (PAH) as well as for other target analytes. At the end of March 2001, we completed the field sample collection in the six selected North Carolina counties. We report here the preliminary results of the analyses of these multiple environmental media for PAH.
