Occupational manganese poisoning

Manganese (Mn) compounds used in industry are mainly oxides and Mn salts (MnO2, Mn3O4, MnCO3…). Mn enters the human body primarily through the respiratory tract in the form of dust or gas, and occasionally through the digestive tract due to poor hygiene practices.

Manganese poisoning is an occupational disease caused by excessive exposure to manganese compounds in the workplace. The symptoms of this disease can vary depending on the level of exposure and duration of contact with manganese.
