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.

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:
The method for extracting and preparing urine samples for analysis of hydroxy-polycyclic aromatic hydrocarbons, pentachlorophenol and 2,4-D is summarized in this SOP. It covers the extraction, concentration and methylation of samples that are to be analyzed by gas chromatography/mass spectrometry.
