Nickel (Ni) & nickel compounds

Heavy metal.
Nickel, a major environmental pollutant, is known for its clastogenic, toxic, and carcinogenic potential. The carcinogenic potential of nickel compounds depends largely on their solubility. The particulate nickel compounds like Ni3S2 or NiO are strong carcinogen, whereas the soluble nickel (II) salts exert weaker effects. (ref. ID; 6934)
