Abstract:Approximately 13 million children are placed in non-parental child care during the work day; however, children's exposures to chemicals in child care centers have not been characterized. To address this data gap, three federal agencies teamed to characterize contaminants in child care centers. The US Department of Housing and Urban Development, in collaboration with the US Consumer Product Safety Commission and the US Environmental Protection Agency, characterized young children's potential exposures to lead, allergens, and pesticides in a randomly-selected nationally representative sample of licensed institutional child care centers. Multi-stage sampling with clustering was used to select approximately 150 child care centers in 30 primary sampling units in the United States. Child care centers were recruited into the study by telephone interviewers. Samples for pesticides, lead, and allergens were collected at multiple locations in each child care center by field technicians. Wipe samples from indoor surfaces (floors, tabletops, desks, etc.) and soil samples were collected at the child care centers. A wide variety of pesticides were detected in the environmental measurements with chlorpyrifos (0.003-63 ng/cm2 of surface; 9-881 ng/g of soil), diazinon (0.004-15 ng/cm2 of surface; 6-89000 ng/g of soil), and cis- (0.001-103 ng/cm2 of surface; 10-116 ng/g of soil) and trans- (0.002-219 ng/cm2 of surface; 2-118 ng/g of soil) permethrin detected in >60% of the child care centers. Based on the questionnaire responses, pyrethroids were the most commonly used pesticides among child care centers applying pesticides. Furthermore, among the 63% of centers applying pesticides, the number of pesticides in the center ranged from 1 to 10 and the frequency of use ranged from 1 to 107 times annually. More detailed pesticide results will be presented.

Although this work was reviewed by EPA, HUD, and CPSC, and approved for publication, it may not necessarily reflect official Agency policy.
