to
metal
Cadmium compounds belong to the most
hazardous pollutants in the environment.
Industry. Cadmium metal is used in the
steel industry and in plastics. Cadmium
compounds are widely used in batteries.
Drinking water. Contamination in
drinking-water may also be caused by
impurities in the zinc of galvanized pipes
and solders and some metal fittings. A
guideline value of 0.005 mg/litre was
recommended for cadmium in drinkingwater.
Toxicity. Cadmium is toxic to a wide
range of organs. Primary targets are the
kidneys, bone, and the lung.
