Manganese (Mn) is a neurotoxicant that, in excess, produces parkinsonism and is commonly found in welding fumes (NIOSH, 1988; Racette et al., 2017; Rodier, 1955).Alterations in striatal and extrastriatal D2 dopamine receptor (D2R) density have been linked with the pathophysiology of parkinsonism (Kaasinen et al., 2000) and Mn neurotoxicity (Criswell et al., 2018b).

Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3).The occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc.

Glauconite is coated with manganese oxide, which causes soluble iron, manganese and hydrogen sulfide gas to bond with oxygen. Bonding with oxygen causes the previously dissolved elements to precipitate and become embedded in the greensand filter. Learn more about greensand filtration for industrial water treatment.
