Jan 01, 2018  1. Introduction. Chronic occupational exposure to manganese (Mn) has been associated historically with a severe, atypical neurologic disorder characterized by parkinsonism, dystonia, cognitive dysfunction, and behavioral dysfunction (Rodier, 1955, Wang et al., 1989).The exposures causing this phenotype were as high as 1,000,000 μg Mn/m 3 (Rodier, 1955, Wang et al., 1989).
