title: Environmental lead exposure and children's cognitive function.
abstract: Recent research has substantially increased knowledge about the effects of low-level lead exposure on children's neurobehavioral development. This update article focuses on two specific areas of recent research: low-level effects on cognitive function, and results from experimental and observational studies designed to prevent or reverse the damaging effects of lead on intellectual development, either through chelation therapy or micronutrient supplementation. Taken as a whole, these studies suggest that there is no safe level of lead exposure for young children and, although small, these effects are enduring and possibly permanent.
