Following occupational exposure, neurobehavioral effects resembling parkinsonism have been observed in a series of manganese workers at exposures well below current occupational standards (13) higher levels of exposure can cause dystonic rigidity and proximal tremor. The late effects of currently asymptomatic exposure are uncertain however, in Chilean workers with past exposure in manganese mines, hand tremor was detectable (14).
