and neurochemical disturbances (Otto and Reiter, 1984; Alfano
and Petit, 1985; Otto et al., 1985; Moore et al., 1986) have
supported the findings of toxic effects from exposure to low
lead levels in humans (<30 µg/dl) and in animals. By testing for
subtle neurologic, cognitive, and behavioral effects in
children, these investigators elucidated neurodevelopmental
toxic effects of lead. The research that produced these findings
was characterized by a variety of methodological approaches:
Multifaceted approaches included a range of methods for
biochemical and neurophysiologic measurements in animals and
(where ethically possible) humans. Studies to evaluate subtle
neurologic and developmental effects of lead included innovative
methods that combined extensive batteries
