Abstract
Eighty behavioral measures of task performance and 5 measures of body burden of lead (7439921) were obtained from 316 lead exposed storage battery workers and 112 controls. The body burden parameters of the experimental subjects were intercorrelated, to the effect that each measure could be predicted from each of the other measures; the measures of the control subjects were not all intercorrelated. Blood lead was not a sensitive measure of changes in functional capacity, while aminolevulinic-acid dehydrase in the blood was found to be the most sensitive predictor of task performance. Intellectual functions were unaffected by increased in body burden of lead, but sensory functions (hearing), neuromuscular functions, or psychomotor functions (tremor, eye-hand coordination, muscular strength and endurance) were all influenced by body burden of lead. The strongest relationships were obtained with tests of neuromuscular functions and psychomotor functions; major changes occurred on the preferred side of the body at lead levels between 70 and 79 micrograms percent.
