We measured blood lead levels and inquired about environmental exposure pathways in 443 children aged 6 mo to 6 y in four lower socioeconomic Denver, Colorado, neighborhoods.
Two neighborhoods were adjacent to a cadmium refinery.
Eight percent of the children had blood lead levels =10 mug/dl and 45% were below the detection limit of 4 mug/dl.
Statistical analyses specific to the problem of below-detection values (i.e., dichotomization of variables, the probability plot method of estimation, and the bootstrap estimate of the standard error) were conducted to detect neighborhood differences.
A child who lived in Globeville, the neighborhood surrounding the refinery, had a slightly higher probability of having a blood lead level =5 mug/dl.
