This paper is directed to those persons concerned with the relationship between blood lead levels and environmental exposures to lead. Information presented in this paper represents one of the largest collections of epidemiological data relating blood lead levels to environmental exposures. The observed annual average ambient air lead concentration ranged from approximately 0.5 ..mu..g Pb/m/sup 3/ to 23 ..mu..g Pb/m/sup 3/, while lead in soil ranged from 50 to 24,600 ppM. Blood lead levels of children (ages 1 to 9 years) are related to a host of environmental variables via regression techniques. Blood lead levels were found to be most influenced by five variables. These variables are: ambient air lead, soil lead, age of the child, dustiness of the home, and occupational status of the parents. It is concluded, based upon the results of this study, that any environmental control strategy should address both the air and the soil. Soil levels in excess of 1000 ppM lead as well as air lead levels greater than 2 ..mu..g Pb/m/sup 3/, 30 day average, were found to be unacceptable.
