Today cadmium can be found in many of the least expected places such as the water supply (through corrosion of galvanized pipes), our food supply, tobacco & tobacco smoke, discharge from metal refineries, run off waste from batteries, paint and metal tooth amalgams. Cadmium is classed as a human carcinogen, so even small levels of toxicity can lead to cancer. Cadmium is in its elemental form a soft, silver-white metal. Smokers and ex smokers often have higher levels of cadmium toxicity, this is because tobacco crops naturally absorb a lot more cadmium from the soil, then burning the tobacco via smoking delivers higher levels of cadmium into the body via the lungs. 3.
