Other reductants that are used to address metals include ferrous iron, sodium dithionite, sulfide salts (calcium polysulfide), and hydrogen sulfide (Dresel et al. 2011). The introduction of substrates to microbially produce reducing conditions favorable to microbial reduction of iron and sulfates also has been used to treat dissolved metal contamination (Waybrant et al. 2002).
Calcium as the element is a grey silvery metal. The metal is rather hard. Calcium is an essential constituent of leaves, bones, teeth, and shells. Calcium is the fifth most abundant element in the earth''s crust and makes up more than 3% of the crust. Calcium does

Many people worry about whether they should stop taking calcium before a DEXA scan. That’s because they wonder whether the calcium might overstate their DEXA results. But this fear is largely unfounded… Undissolved calcium could influence your DEXA scan reading— if you take calcium tablets.⁶ Calcium tablets contain binders that can delay dissolution of the tablets in your gut.
