Cadmium in Drinking-water WHO. The most common sources of cadmium toxicity are foods such as rice and wheat which are grown in soil contaminated by sewage sludge, super phosphate fertilizers and irrigation water. Large ocean fish such as tuna, codfish and haddock concentrate within their tissues relatively large amounts of cadmium. Cadmium levels in the environment vary widely. As stated above, cadmium emissions to the environment are normally transported continually between the three main environmental compartments, air, water and soils, but a steady state flux is probably achieved and the general levels can reasonably well be established..
