Manganese poisoning

Manganese poisoning is a poisoning reaction caused by the body's excessive intake of manganese. Acute manganese poisoning can be caused by oral potassium permanganate or inhalation of high concentration manganese oxide smoke. Acute corrosive gastroenteritis or irritating bronchitis, pneumonia, etc. are its main clinical manifestations. Chronic manganese poisoning is mainly seen in workers who inhale manganese smoke for a long time. The clinical manifestations are mainly extrapyramidal nervous system symptoms, neurobehavioral dysfunction and mental disorders. Those who are more exposed to manganese include manganese ore mining and smelting, manganese electrode manufacturing, welding and wind-cut manganese alloys, and industrial workers who manufacture and apply manganese dioxide, permanganates and other manganese compounds.
