Neuropsychological effects of chronic lead (7439921) exposure were studied in children. Children living in close proximity to ore smelters in Texas and Idaho received neuropsychological evaluations and neurologic and psychologic assessments. Blood samples were taken. Diffuse impairment of nonverbal cognitive and perceptual motor skills was observed in children in Texas. There was also impairment of fine motor skills. In Idaho, while none of the children had clinical neurologic disease or pathologic conduction velocities, there was a significant relationship between blood lead concentrations and decreases in maximal motor nerve conduction velocity. The authors conclude that the ore smelters are primary localized sources of environmental lead concentration and are responsible for increased lead absorption among the children living nearby.
