Principle Routes of Exposure

Not available.

Potential Acute Health Effects

Inhalation Acute exposure to excessive manganese affects the respiratory and the central nervous system. Inflammation of the lungs may occur after acute toxic inhalation overexposure. "Manganese pneumonia" has been reported in mine workers with clinical signs of alveolar inflammation, marked dyspnea, shallow respiration, subsequent facial cyanosis and an increased susceptibility to infection. Acute renal failure, abdominal pain, and mild methemoglobinemia have been reported following the ingestion of manganese- containing products. Ingestion No known significant effects or critical hazards. Skin No known significant effects or critical hazards. Eyes No known significant effects or critical hazards.

Potential chronic health

effects : Inhalation of large quantities of manganese containing dusts over many years may result in damage to the central nervous system, with symptoms of sleepiness, tremors and weakness in the legs, slurred speech, emotional disturbances, loss of balance, and in more advanced cases, an irreversible condition with symptoms similar to Parkinsons or Lou Gehrig's disease including a mask-like facial expression, spastic gait, tremors, slurred speech, fatigue, anorexia, apathy, and inability to concentrate in more advanced cases. The neurologic disorder that develops is known as "manganism". A syndrome may develop with symptoms of compulsive behavior, emotional volatility and hallucinations. High levels of manganese in the blood may increase anemia by interfering with iron absorption. Iron deficiency may increase an individula's susecptibility to manganese. Studies suggest that populations at risk of adverse effects due to manganese exposure are infants and those with existing iron deficiency. Disorders are reversible if recognized early and overexposure is eliminated. Carcinogenicity : No known significant effects or critical hazards. Mutagenicity : No known significant effects or critical hazards.
