Abstract:
Consistent association has been found in 4 independent studies between disruption of visual-motor integration and reaction performance and markers of lead exposure (blood, teeth) in children, but not for intelligence deficit; blood-lead levels were typically below 30 micrograms/dl in these children. In order to demonstrate the persistent nature of Pb-induced neurobehavioral deficit experimentally rats were studied after cessation of dietary Pb-exposure in a variety of behavioral tasks. Persistent retention-deficit was found for visual discrimination-learning and for radical arm-maze performance.
