WebMercury isotope ratios in fish tissues have been used to infer sources and biogeochemical processes of mercury in aquatic ecosystems. More experimental studies are however needed to understand the internal dynamics of mercury isotopes and to further assess the feasibility of using fish mercury isotope ratios as a monitoring tool. WebThe mercury (I) ion, Hg 22+, is diatomic and stable. Mercury (I) chloride, Hg 2 Cl 2 (commonly known as calomel ), is probably the most important univalent compound. It was used in antiseptic salves. Mercury (II) chloride, HgCl 2 (also called bichloride of mercury or corrosive sublimate), is perhaps the commonest bivalent compound.
