ENVIRONMENTAL ASPECT OF MANGANESE CHEMISTRY

2010-7-3  Manganese is considered to be the 12th most abundant element in the biosphere. Its concentration in the Earth’s crust reaches as much as 0.098 mass %. The concentration of manganese in the ocean crust is about 60% greater than that in the continental one [70]. It is widely distributed in soil, sediment, water and in biological materials.
