Manganese — Health Professional Fact Sheet

However, manganese toxicity has occurred in people working in such occupations as welding and mining who were exposed to high amounts of manganese from chronic inhalation of manganese dust [1,41]. People who consume water containing high levels of manganese (in some cases as high as 28 mg/L) have also developed manganese toxicity [4,42].
