CTEPP DATA COLLECTION FORM 10 (PERIODS 1-3): DAY CARE CENTER CHILD ACTIVITY DIARY AND FOOD SURVEY .

Impact/Purpose:

The CTEPP study is the largest aggregate exposure study of preschool children (ages 2 to 5 years) conducted in the United States. The CTEPP study was designed in part to fill in critical data gaps on young children’s exposures to pesticides in response to the Food Quality Protection Act (FQPA) of 1996.

Description:

This data collection form collects information on the child's activities at the day care center over the 48-hr monitoring period. The diary is divided into three time periods over the 48-monitoring interval. The Food Survey collects information on the frequency and types of fruits, vegetables, meats, and dairy products that the child ate over the past year.

The Children's Total Exposure to Persistent Pesticides and Other Persistent Pollutant (CTEPP) study was one of the largest aggregate exposure studies of young children in the United States. The CTEPP study examined the exposures of about 260 preschool children and their primary adult caregivers to pollutants commonly found in their everyday environments. The major objectives of this three-year study were to quantify children's aggregate exposures, to apportion the exposure pathways, and to identify the important exposure media. Participants were recruited from randomly selected day care centers and homes in six North Carolina and six Ohio counties. Monitoring was performed over 48-hr periods at the children's homes and/or day care centers. Multimedia samples that were collected included duplicate diet, drinking water, indoor air, outdoor air, urine, floor dust, play area soil, transferable residues, and surface wipes (hand, food preparation, and hard floor). The samples were extracted and analyzed by gas chromatography/mass spectrometry for over 50 pollutants including pesticides, phthalate esters, phenols, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. In addition, 20% of the preschool children were videotaped for about two hours at homes in Ohio to supplement the activity diaries and observations. All of the measurement data and other supplemental information were incorporated into the CTEPP database. The data were statistically analyzed to quantify the concentrations of the pollutants in multimedia and to estimate the preschool children's exposures through the inhalation, ingestion, and dermal routes. This database is considered one of the largest resources for characterizing young children's exposures to pollutants in their everyday environments.
