Workers from a primary nonferrous smelter were examined for neurobehavioral disorders. The examination of 403 workers and the comparison cohort of 305 residents from two surrounding communities included tests of maximum motor conduction velocity (MCV) of the peroneal and ulnar nerves; blood lead (7439921) concentrations; eye hand coordination and visual reaction time; and personality. Subjects also completed a symptom questionnaire. Mean blood lead concentrations among the workers ranged from 30 to 56 micrograms per deciliter; among the residents it ranged from 10 to 22 micrograms per deciliter. When compared with community residents, smelter workers had a 10 percent increase in choice reaction time, increased prevalence of peripheral nerve dysfunction, increased feelings of depression and hostility, and slightly decreased MCVs. The authors conclude that the degree of neurologic and psychological impairment among the workers remains uncertain.
