[Neurotoxicity of aluminum. Study of a long-term exposed sample of workers of an aluminum powder industry].

Within the framework of a transverse study, the mental performance of a group of subjects exposed to aluminium over many years (n = 32; aluminium powder industry) was compared with that of a structurally similar control group (n = 30). Neuropsychological and electrophysiological tests revealed no signs of cognitive performance, despite aluminium burdening. Aluminium levels in plasma and urine were elevated.
