    Abstract:
    To assess environmental lead contamination in the household environment of children in high-risk areas of California, three urban locations were surveyed by the California Department of Health Services. Plant, soil, and dust lead levels were measured and a questionnaire was administered. This survey estimates that 3 million homes in California (27%) may have exterior paint lead levels > or = 5000 ppm, and 1.3 million homes (12%) may have interior paint lead levels > or = 5000 ppm. The highest concentrations of lead in paint were found on exterior surfaces and, for homes built between 1920 and 1959, on trim. Age of housing was the best predictor of lead in soil and dust; homes built before 1920 were 10 times more likely to have soil lead levels > or = 500 ppm compared to post-1950 homes. Most of the variability in dust lead levels could not be explained by factors measured in this survey. Sources of lead in the home were more highly correlated with lead dust concentration levels than they were with lead dust loading levels. Households with members reporting a lead job were twice as likely to have high dust lead levels compared to households with no one reporting a lead job. The significant differences in dust lead concentration levels between communities were not reflected in differences in dust lead loading levels. Measuring dust lead loading levels does not appear to be a meaningful sampling method for risk assessment in the context of prioritizing abatement.
