Lead neurotoxicity: From exposure to molecular effects

We provide an introductory overview of the magnitude of the problem of Pb2+ exposure to bring forth the reality that childhood Pb2+ intoxication remains a major public health problem not only in the United States but worldwide. Finally, the latest research offers some hope that the devastating effects of childhood Pb2+ intoxication in a child's ability to learn may be reversible if the appropriate stimulatory environment is provided.
