Abstract
Lead concentrations were determined for soil samples collected at 37 child day care centers located within the greater Cincinnati area. Soil samples were collected within 1.5 m of the exterior walls and throughout the remainder of the outdoor playgrounds of each of the child day care facilities. The soil lead concentrations were utilized as indicators of lead contamination from vehicle emissions and lead based paints. Mean lead concentrations were determined through Inductively Coupled Plasma-Mass Spectrometry. Soil lead concentrations were significantly higher within 1.5 m of the exterior walls than the rest of the outdoor play areas of the child day care centers (P < .05). There was a highly significant association between higher soil lead concentrations for child day care centers built prior to 1980 (P < .01). It was also found that a highly significant association exists between higher soil lead concentrations for child day care centers located within 2.5 km of the nearest interstate highway (P < .01). The findings of this research point to a clear need for concern about lead contamination at child day care centers and other facilities that large numbers of children frequent on a daily basis.
