Low lead and cadmium levels and childhood visual-perception development.

Abstract

This study investigated possible relationships of lead and cadmium levels to childhood visual-perceptual development. Hair-metal concentrations of lead and cadmium were analyzed in 25 children who were having learning problems. They were also administered the Bender Visual-motor Gestalt Test. Lead and cadmium levels correlated significantly and negatively with age-deviations of Bender errors. A continuing reexamination of lead and cadmium levels is needed because levels previously thought harmless may be associated with decrements in childhood visual-perceptual development.
