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.


U.S. EPA. CTEPP NC DATA COLLECTED ON FORM 04: PARENT PRE-MONITORING QUESTIONNAIRE. U.S. Environmental Protection Agency, Washington, DC, EPA/600/C-11/016, 2011.


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.


This data set contains data concerning the individuals living in the home and the possible sources and routes of exposure, and the activity patterns of the preschool children. The parent was asked questions related to the age of their home; frequency of cleaning carpets, rugs, and floors; types of heating and air conditioning devices; and traffic conditions near the home; on individuals living at the home (smoking habits, employment); sources of water for drinking and bathing; types of pets; frequency of changing automobile oil in the driveway or garage; and applying pesticides within 7 days of field sampling; and on their child’s frequency of playing with or eating dirt, sand, or snow; walking barefoot inside or outside the home; frequency of placing hands or objects into the mouth; and frequency of bathing and washing hands.

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 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.
