Manganese: A Life Essential Element
Manganese is an essential element for a variety of biological, industrial, and scientific processes. It has no color but possesses a distinct hardness and is the twelfth most abundant element on Earth.
Manganese plays a critical role in many plant and animal processes as well as in almost all modern technological feats. Its discovery has not only helped to make the modern world possible but has also opened the door to understanding the roles of other elements in nature.
History and Discovery of Manganese
Manganese was first discovered by Johann Gahn in 1774 in Sweden. It was initially thought to be a combination of iron and magnetite because of its natural oxide form. It wasn’t until 8 years later that chemist Carl Scheele realized it was not two elements but one, separated from iron oxide.
Besides Gahn and Scheele, a few other individuals have been credited with the discovery of manganese, among them Johann Heinrich Pott and Josef Berzelius.

Uses of Manganese
The most common use of manganese is in steel production. It helps to give steel its strength and durability. Manganese can also be found in alloys used in aluminum cans and rechargeable batteries. It is a critical component in industrial fertilizers and pesticides and is used in the manufacturing of plastics.
Manganese is also essential for the development of nerve cells as well as converting some hormones into active forms.
Safety Precautions
Even though manganese is essential in trace amounts, it can become a health hazard when not handled correctly. Inhaling or touching manganese dust, fumes, or vapors can cause long-term health problems, such as neurological problems or even permanent brain damage.
It is important to take all necessary safety precautions when dealing with manganese, including wearing proper protective gear and avoiding contact with the substance.
Conclusion
Manganese remains an important element for a variety of everyday processes. Not only does it have numerous industrial applications, but it is also essential for proper health and development in animals and humans.
Despite its importance, extreme caution must be taken when handling or dealing with anything associated with manganese. By understanding its importance it is possible to make smart choices on its consumption and use.
