Since it does not play any beneficial effect in the organism, there is no normal Pb blood level recognized. Lead is considered a developmental neurotoxicant: clinical and experimental evidence indicate that environmental Pb exposure induces neurobehavioral alterations in developing organisms, manifested as learning disabilities, hyperactivity, and an altered response to drugs. Present studies are focused on the identification of subpopulations at risk in today toxicological scenario, dominated by multiple- contaminant exposures or associated with adverse situations
