WARNING! DATA USE RESTRICTIONS

Read Carefully Before Using

The EPA does all it can to ensure that the identity of survey participants cannot be disclosed. All direct identifiers, as well as any characteristics that might lead to identifications, are omitted from the data. Any intentional identification or disclosure of a person or establishment violates the assurances of confidentiality given to the providers of the information. Therefore, users will (1) use the data in this study for statistical reporting and analysis only; (2) make no use of the identity of any person or establishment discovered inadvertently and will advise the HEDS Administrator of any such discovery; (3) will not link this data with individually identifiable data from other EPA or non-EPA data.

By using the data you signify your agreement to comply with the above-stated statutorily based requirements.

Impact/Purpose:

The major objectives of this three-year study were to quantify children's aggregate exposures, to apportion the exposure pathways, to identify the important exposure media, and to identify the important hypotheses for future testing.

Description:

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, to identify the important exposure media, and to identify the important hypotheses for future testing. Participants were recruited from randomly selected day care centers and homes in six North Carolina (NC) and six Ohio (OH) 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 2 hours at homes in OH to supplement the activity diaries and observations. All of the measurement data and associated information was incorporated into the CTEPP database. The data were statistically analyzed to quantify the concentrations of these pollutants in multimedia and to estimate the exposures through the inhalation, ingestion, and dermal routes of the preschool children through environmental sampling, time?activity diaries, food diaries and questionnaires. This database is one of the largest resources for characterizing young children's exposures to pollutants in their everyday environments.
