Cadmium is a metal found in natural ore deposits and is used
in the manufacture of machinery, transportation, and electronic equipment.
It is also found in some batteries and paint pigments. This heavy metal reaches
the environment through the leaching of ore deposits, from industrial releases
and landfills and corrosion of water pipes. Metal processing (smelters) are
also major sources.
Exposure to cadmium in water can cause a variety of acute and
chronic effects including vomiting, muscle cramps and damage to
the liver and kidneys.
