TL;DR
This study measured pesticide, allergen, PCB, and lead levels in tribal childcare centers in the Pacific Northwest to understand children's environmental exposures.
Contribution
This is the first study to characterize environmental health in tribal childcare centers in the Pacific Northwest.
Findings
Pesticides like permethrin and piperonyl butoxide were detected in all childcare centers.
Lead was found in most surface wipes and all outdoor soil samples, but at lower levels than previously reported.
Allergen residues were present at very low concentrations in vacuum dust samples.
Abstract
Children’s potential exposures to chemical and biological agents in tribal childcare centers are not well characterized. (1) The environmental health of childcare centers in Portland Area Indian Country was characterized by measuring selected pesticides, polychlorinated biphenyls (PCBs), allergens, and lead (Pb) in outdoor soil and indoor dust. (2) We compared our results to other studies of childcare centers in both the United States and globally. At 31 tribal childcare centers in Washington, Oregon, and Idaho, we collected indoor dust and outdoor soil samples from at least one classroom, multipurpose room, and outdoor play area. Number of rooms sampled depended on facility size. Surface wipes were collected from the floor, play/work surface, and windowsill and analyzed for selected pesticides and PCBs. Vacuum samples were collected from the floor and analyzed for selected allergens.…
