Manganese is a naturally occurring element found in rocks. Trace levels of manganese are found in foods and water. These levels are not dangerous to human health and therefore manganese removal is not necessary. Manganese removal is necessary when harmful levels of manganese are present in drinking water and iron, steel, coke oven, and mining operation work environments, some pesticides and fuel additives.
Manganese removal is necessary to reduce the threat of harmful health consequences associated with manganese exposure. Inhalation or ingestion of manganese substrates or fumes can cause brain, liver, kidney, respiratory, motor and sexual problems. Manganese can also be harmful to fetal development.
Inhaling large amounts of manganese fumes over an extended period of time can cause a degenerative brain disorder called Parkinsonism. Manganese fumes have been known to cause Parkinsonism since 1837. It is estimated that forty percent of all welders show some signs of this disorder. Symptoms of this debilitating disease include: tremors, shakes, loss of balance, impotency, inability to control facial muscles, slurred speech, slow or difficult movements, drowsiness, and muscle cramps.
Manganese levels in the air and water are regulated by the Environmental Protection Agency and the Occupational Safety and Health Administration. These government agencies require manganese removal when permissible levels are exceeded. Permissible levels of manganese for an eight hour work day are set by OSHA at five milligrams per cubic meter. The EPA has set the permissible levels of manganese in drinking water at 0.05 milligrams of manganese per liter of water.
Work environments that expose employees to manganese fumes are required to provide a number of manganese removal methods to protect their workers from harmful exposure levels. Manganese removal in the work environment requires exhaustive ventilation systems. Personal protective equipment, such as air respirators, also aid in manganese removal and can protect workers from dangerous manganese exposure.
Manganese removal from drinking water can be done in a few ways. The most common method of manganese removal is a process of oxidation and filtration. Oxidation can be performed using chlorination, potassium permanganate, ozone, and tray aerator methods. Filtration can be completed through manganese greensand, anthra-sand (iron-man sand), electromedia, and macrolite methods of manganese removal. Sequestration and ion exchange are two other methods of manganese removal in drinking water.
If you have been exposed to dangerous levels of manganese, or are experiencing any of the symptoms of manganese poisoning, you should seek medical attention as soon as possible. If you have suffered injury due to manganese you may wish to contact an attorney to determine your eligibility in filing a civil lawsuit to recover damages.
