Pure cadmium is a
soft, silver-white metal found naturally in small
quantities in air, water and soil. The main industries
that use cadmium are metal smelting, electronics,
nuclear power, paint pigment production, and other
metal working and refining companies. Higher levels
of cadmium may be found in soil or water near
industrial areas or hazardous waste sites. Surface
water can contain low levels of dissolved cadmium.
Cadmium in water tends to sink. Health effects
caused by cadmium depend on how much has entered
your body, how long you have been exposed and
how your body responds. It also can cause bones
to become weaker. If you eat food or drink water
that contains large amounts of cadmium, stomach
irritation, vomiting and diarrhea may result.
