also known as Manganese in Red Blood Cells
Manganese is a very common compound that can be found everywhere on earth. Manganese is one out of three toxic essential trace elements, which means that it is not only necessary for humans to survive, but it is also toxic when too high concentrations are present in a human body. Manganese deficiency produces growth disorders, alters skeletal and cartilage formation and impairs reproduction. Industrial workers absorb manganese mainly through the lungs.
