Federal agencies have completed the first national study of lead, pesticides, and allergens in U.S. child-care facilities.
Joey Y. Zhou of the Department of Housing and Urban Development (HUD) and his colleagues sampled dust, play-yard soil, and residues on windowsills and other surfaces at 168 sites that make up a representative sample of the nearly 100,000 licensed child-care centers in the United States.
