large amounts of cadmium from low cadmium
content soils [3]. Cadmium (Cd) works by
disrupting the normal state of a cell. Its similar
structure to zinc and calcium allows it to interfere
with the absorption of these elements, and it
similarly inhibits copper and iron. Like most
heavy metals, when absorbed into the body
cadmium is stored in the liver and kidney of the
animal. Cadmium is an accumulative poison,
meaning that it builds up slowly over time in the
bodies of exposed animals. Cadmium poisoning
affects nearly all major organ systems and has
noted reproductive effects, including decreased
testes size and infertility. Additionally, because of
this element's interference with the absorption of
the mineral calcium, cadmium poisoning can also
severely impact the healthy function of the bones
[4]. Increases in cadmium levels in soil result in
an increase in the uptake of cadmium by plants,
although the extent to which this happens will
depend on the soil pH, plant species and the part
of the plant, as well as other soil characteristics
[5].
