Abstract:
Two cross-sectional studies were conducted at a German aluminum (Al) powder plant to evaluate possible nervous system effects from occupational Al exposure. The investigation included biological monitoring, a neuropsychological test battery, and event-related P300 potentials. Neurophysiologic findings in workers chronically exposed to Al dust did not differ from non-Al-exposed controls from the same plant. The authors suggest that chronic exposure to Al dust, at the levels documented in this study, does not induce measurable cognitive decline.
