Manganese, Plasma

In evaluating toxicity, the serum level may have returned to normal while neurological damage persists.

Toxic exposure may occur from dry cells, fungicide (maneb), and in the steel industry or chemical industry. Manganese is present in the coloring agents for glass and soap, in paints, varnish, enamel, and in linoleum. It is used in the manufacture of chlorine gas and now 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 presen

In evaluating possible deficiency states, the human deficiency syndrome is poorly defined, making interpretation difficult. Levels are reportedly reduced mildly in epilepsy, and raised in hepatitis or jaundice. Manganese levels are 60% lower than normal in hemodialysis patients.
