2024年2月23日 · Male workers exposed to manganese also have a higher risk of fertility problems. Prolonged exposure to high manganese concentrations (>1 mg/m 3) in air may lead to a Parkinsonian syndrome known as "manganism." Chronic exposure to the manganese-containing pesticide, maneb, may cause Parkinson-like symptoms.

Manganism; asthenia, insomnia, mental confusion; metal fume fever: dry throat, cough, chest tightness, dyspnea (breathing difficulty), rales, flu-like fever; low-back ...

Workers chronically exposed to concentrations of manganese dust averaging 20 mg/m 3 showed signs of manganism [Smyth et al. 1973]. Revised IDLH: 500 mg Mn/m 3 Basis for revised IDLH: The revised IDLH for manganese is 500 mg Mn/m 3 based on acute inhalation toxicity data in animals [Gupta et al. 1981].

Martonik (1976, as cited in ACGIH 1986/Ex. 1-13, p. 357) reported that the fume of manganese has greater toxicity than does the dust. During a two-year period, at least one case of acute manganese poisoning was documented at a fume concentration level of 7.5 mg/m 3, and another case at the same welding operation may also have involved manganism.
