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.
Cadmium is produced mainly as a byproduct of mining, smelting and refining of zinc and, to a lesser degree, as a byproduct of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickelcadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.
