A Probabilistic Exposure Assessment for Children Who Contact CCA-Treated Playsets
The U.S. Environmental Protection Agency (EPA)'s Office of Research and Development (ORD), National Exposure Research Laboratory (NERL), in collaboration with the U.S. EPA's Office of Prevention, Pesticides, and Toxic Substances (OPPTS), Office of Pesticide Programs (OPP) has conducted a probabilistic exposure and dose assessment on the arsenic (As) and chromium (Cr) components of Chromated Copper Arsenate (CCA). The purpose of this assessment is to help determine the potential health risks to children from contact with CCA-treated wood in playsets and home decks and CCA-contaminated soil around these structures.
