Cadmium
Toxic element
One of the group of so-called heavy metals, cadmium
accumulates in the body, especially in the liver and kidneys, as excretion is
very slow. A high level of accumulation can eventually result in kidney damage.
Other effects of cadmium excess can include anaemia (probably because cadmium
competes with copper and iron, needed for blood formation), high blood pressure
(probably due to kidney damage), and itai-itai disease in Japan.
Cadmium is a pollutant which is present in the air around industrial
smelting and plating plants, and can be inhaled through the lungs. It is also
present in galvanized water pipes, which may contaminate drinking water that
passes through the pipes. Tobacco smoke contains cadmium (and lead) and may
cause smokers to inhale up to 5 mcg of cadmium per day. Silver (amalgam) tooth
fillings may also contain cadmium.
Some foods are contaminated with small amounts of cadmium: oysters, liver
and kidneys, and crops which have been grown on soil contaminated with cadmium
or dressed with cadmium-containing fertilizer.
