High levels of manganese are found mostly in the steel making and welding industry. Exposure to dangerous levels of manganese may cause manganese-induced Parkinsonism, a disease with symptoms similar to Parkinson's disease.

The disease affects the central nervous system, kidneys, and liver. Its most crippling effect is the permanent damage on the part of the brain that controls body movement, which results in diminished motor skills. Symptoms of the disease may appear several years after the exposure. The toxicity of manganese has been recognized since 1837 for its ability to affect the central nervous system, yet workers have been and continue to be exposed to the toxic fume emissions. Welders are especially at great risk as they breathe in toxic levels of manganese fumes on a regular basis. Over time, breathing these fumes causes permanent brain damage. Also, people who live near such factories can be exposed to manganese dust in the air or in their drinking water. Symptoms of Parkinsonism and manganism can include muscle stiffness, loss of balance, muscle aches and cramping, shakiness, tremors, distorted facial expression, difficulty walking, short-term memory loss, difficulty speaking, fine motor skill loss, and some men may become sterile.
