About Manganese Dioxide: Properties & Uses
An inorganic compound, blackish or brown solid, it occurs naturally as the mineral pyrolusite which is the main ore of Manganese and a component of Manganese Nodules.

it is used for a wide variety of purposes including the manufacture of batteries,beverage cans, agricultural pesticides and fungicides and electronic circuitry. In addition, its one of the most commonly used and least understood applications for removing iron, manganese, hydrogen sulfide, arsenic and radium.

While handling
, avoid inhalation and ingestion as well as contact with eyes and the skin. Manganese Dioxide is as an oxidizing agent should not be stored with reducing agents or in a place that is susceptible to fire / explosion. Store it in a tightly sealed container in dry place away from reducing agents.

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects:

Skin: Causes skin irritation.

Eyes: Causes eye irritation from mechanical action.

Inhalation: Inhalation manganese dioxide fume can cause "fume metal fever", a flu-like illness characterized by chills, fever, aching muscles, dryness in the mouth and throat, headache. It may irritate the respiratory tract. It may increase the incidence of upper respiratory tract and pulmonary infections. It may also cause emphysema, and acute pulmonary edema. Absorption of inorganic manganese salts through the lungs is poor, but may occur in chronic poisoning.

Ingestion: May cause abdominal pain and nausea. Although manganese salts are poorly absorbed through the intestines, they may produce hypoglycemia, and decreased blood calcium levels could absorption occur.

Chronic Potential Health Effects:

Chronic exposure to Manganese dioxide can lead to manganese poisoning, called Maganism. It primarily involves the central nervous system. Early symptoms include languor, sleepiness, poor appetite, and weakness in the legs. Later effects which may include a stolid mask-like appearance of the face, muscle cramps, twitiching and tremors, changes in mood and personality, emotional disturbances such as uncontrollable laughter and a spastic gait with tendency to fall while walking as well as anemia are also findings in workers exposed to the dust or fumes of manganese compounds. Later symptoms are identical to Parkinson's disease. Repeated or prolonged exposure may also damage the liver and may cause a decrease in the heart rate.

Repeated inhalation of manganese dust may also cause Manganese Pneumonitis, bronchitis with cough, phlegm, and/or shortness breath.
