Manganese poisoning is referred to as manganism, the result
of excessive or prolonged exposure to manganese. When the
human body absorbs a large amount of manganese there is a
toxic effect, resulting in serious health conditions and diseases.
Sometimes people use manganism and Parkinsons disease
to describe the same adverse manganese effect due to the similarity
of the conditions. Manganese has a very long elimination from
the central nervous system so the effects of manganism are
not always immediately evident.
are considered to be at the highest risk for developing manganism.
There are three different stages that are differentiated in
manganism, including behavioral changes, parkinsonian features,
and dystonia and gait disturbances. The onset of manganism
can be observed through symptoms of fatigue, headache, muscle
cramps, loss of appetite, apathy, insomnia, and a diminished
Other symptoms of manganism can include:
- muscle stiffness
- breathing and swallowing problems
factory workers, and communities in areas of high manganese
industry are also at an increased risk for developing manganism.
Workplace hazards are considered the highest risk for developing
manganism so understanding how to follow workplace standards
to reduce risk is especially important to ensuring the well
being of individuals that work closely with the dangerous
element. Communities that exist in areas where manganese is
released into the air will have a higher risk for manganism.
Unfortunately, manganism signs are similar to many other
non-occupational diseases and can be disregarded or have delayed
diagnosis because of this. In addition, regular physicians
are not adequately trained to recognize signs of manganism
and may attribute signs and symptoms of it to something else.
People are exposed to manganese everyday in the air, soil,
water, and food but at levels recommended to be less than
11 mg daily.
safety guidelines have been established to protect the
workers from toxic levels of exposure that can cause manganism
and employers that fail to properly institute these guidelines
are risking the health of everyone working in the conditions.
