While it is known that toxic metals contribute individually to child cognitive and behavioral deficits, we still know little about the effects of exposure to multiple metals, particularly when exposures are low. We studied the association between children's blood lead and hair arsenic, cadmium, and manganese and their performance on the Bayley Scales of Infant Development III. Ninety-two presch...

BACKGROUND Environmental lead exposure among adults may increase blood pressure and elevate the risk of hypertension. The availability of data on blood lead levels (BLL) in adult Brazilian population is scarce and population-based studies are important for screening the population exposure and also to evaluate associations with adverse health effects. The goal of this study was to examine the a...

During 1991-1994, an estimated 930,000 U.S. children aged < 6 years had blood lead levels (BLLs) > or = 10 micrograms/dL, and the risk for an elevated BLL was greatest among children who were non-Hispanic black or Mexican American, from low-income families, living in large metropolitan areas, or living in housing built before 1946. Because risk for lead exposure is associated with several diffe...

INTRODUCTION Although lead paint and leaded gasoline have not been used in the US for thirty years, thousands of US children continue to have blood lead levels (BLLs) of concern. METHODS We investigated the potential association of modeled air lead levels and BLLs ≥ 10 μ g/dL using a large CDC database with BLLs on children aged 0-3 years. Percent of children with BLLs ≥ 10 μ g/dL (2000-2007)...

Background: Lead poisoning is an issue of concern in developing countries and high levels of lead in blood could be resulted following occupational and environmental exposures. Several reports have raised concerns on the increasing prevalence of lead intoxication among opioid addicts. This study investigated the clinical manifestations and demographic data of subjects who were ...
