Manganese poisoning may produce symptoms of fever, muscle pains, chills, and dryness of the mouth and throat. Chronic exposures to manganese may produce effects on the Central Nervous System (headache, restlessness, irritability, personality change, hallucinations, and hearing impairment). Levels may be reduced mildly in epilepsy and raised in hepatitis or jaundice.
Manganese is an essential mineral, but high concentrations can cause nausea, headache, and psychiatric disturbances with neurological damage similar to Parkinson disease. Toxic exposure may occur from fungicides and in the steel or chemical industries. Manganese is present in the coloring agents for glass and soap, in paints, varnish and enamel, and in linoleum. It is used in the manufacture of chlorine gas and in lead-free gasoline. Industrial manganese poisoning has been recognized since 1837. Some water supplies are sufficiently contaminated by manganese that endemic psychiatric and neurological disease is present. Price: $92.50 |
