    Manganese is an essential trace metal. The dysregulation of manganese seen in a broad spectrum of neurological disorders reflects its importance in brain development and key neurophysiological processes. Historically, the observation of acquired manganism in miners and people who misuse drugs provided early evidence of brain toxicity related to manganese exposure.

  • TOXICITY SUMMARY FOR MANGANESE

    populations exposed for a lifetime to manganese concentrations in drinking water ranging from –2300 μg/L (Kondakis et al. 1989). A chronic (EPA 1995) and subchronic RfD (EPA 1994) of mg/kg/day for dietary exposure has been calculated by EPA from a human NOAEL of mg/kg/day, which was determined from a series of epidemiological studies (Schroeder et al. .
