Cadmium occurs in nature as cadmium sulphide in greenockite, CdS, which is very rare. It is widely diffused in calamine, blende, and other zinc ores, forming, in some cases, as much as 2 or 3 per cent, of the ore. Oxide of cadmium forms the “ brown blaze ” of the zinc smelters.

Cadmium considerably exists in environment, as a result of human activities, such as the use of fossil fuels, metal ore combustion and waste burning. Leaking sewage sludge to agricultural soil may cause the transfer of cadmium compounds adsorbed by plants that may play a significant role in food chain, and accumulate in various human organs.
