Abstract

Thirteen workers with no known prior exposure to lead had an exposure history from two weeks to eight months with a median blood lead level of 72 μg/dl (37-115 μg/dl). Free erythrocyte protoporphyrin (FEP) levels, ranging from 68 to 479 μg/dl with a median of 265 μg/dl, were highly correlated with the length of exposure. A neurobehavioral battery which emphasized memory functions was administered to the lead-exposed and nonexposed control workers. Significant differences were obtained in tests of visual intelligence and visuomotor functions. A new finding was the significant decrement in performance on an auditory task for word span. These findings have never been previously described in a group with such brief lead exposure.
