Blood Lead and Decision Speed in Working Age Adults
Lead is a central nervous system poison. Healthy People 2010 established a target blood lead level (BLL) for children of 0 μg/dL by 2010, but is silent with regard to any changes in BLLs standards for working age adults. In this paper, the relation of BLL to performance on two neurobehavioral tests …

Investigation of the Distribution of Lead (Pb) in Soil in Rochester, NY: Correlation with Children’s Blood Lead Levels
Despite the outlawing of both leaded paints and gasoline decades ago, lead poisoning remains a severe health issue, particularly for children aged 5 and under due to their hand-to-mouth tendencies and underdeveloped gastrointestinal tracts. Lead from paint typically only presents itself as an issue …

Environmental lead exposure among inner-city Cape Town children : a study of associated risk factors
Risk factors for lead exposure among children in South Africa have not been well documented. This study elucidated important factors which co-vary with lead in increasing children's risk of exposure. Two study designs were used. First, a cross-sectional analytical study involving first grade school …
