Workers are chronically exposed to manganese everyday at high levels. Welders especially have been affected by manganese poisoning, which alters nervous system functioning due to exposure to toxic fumes, fires, dust, and other hazards.

People who work with Manganese are at a high risk for developing Manganism. High-risk professions may include:

Welders
Miners
Railroad workers
Steel workers
Factory workers
Agricultural workers who work with pesticides

Manganese can be found in many chemicals and agents used in the workplace. These include:

Cleaning solvents
Dry cleaning solvents
Spray paints
Paint removers
Gasoline fuel
Kerosene fuel
Degreasers
Lubricants

Obvious symptoms may not develop until after age fifty; however, less noticeable symptoms of Manganism may appear in individuals who are younger and who have experienced prolonged low-level exposure to manganese. If you believe you are suffering from exposure to manganese, see a doctor immediately.
