Título Manganese exposure in steel smelters - A health hazard for the nervous system
Información bibliográfica Aug. 1991, Vol.17, No.4, p.255-262. Illus. 22 ref.
Resumen Study of the effects of low-level exposure to manganese (0.19-1.39mg/m3 for 1-45 years) on 30 men (aged 20-64 years) from two steel smelting works and 60 unexposed referents (aged 22-65 years). The investigation covered: a general health inquiry, electroencephalography (EEG), brain-stem and cerebral auditory evoked potentials, diadochokinesometry, simple and complex reaction time, finger tapping, digit span, mental arithmetic, vocabulary, a coding task, manual dexterity, diagnostic interview scheme, dynamic rating scale for neurasthenic syndrome, and a comprehensive psychopathological rating scale. No group differences were found concerning health, the EEG or the psychiatric examinations. However, the diadochokinesis was slower, the P-300 latency and reaction time were increased, and finger-tapping and digit-span performance were impaired in the exposed group. The effects are interpreted as early (subclinical) signs of disturbances of the same type as parkinsonism. (A longer version of this article was published as a Swedish-language monograph in 1990, see CIS 91-949).
