Zusammenfassung

Cadmium is a non essential and relative rare heavy metal in the earth, although in recent decades its accumulation increased considerably as a consequence of the industrial activity. Cadmium contamination can causes severe problems for living organisms, and can be highly toxic to humans. Humans can be affected by cadmium through ingestion of contaminated vegetables. For this reason, it is important to find out the mechanisms involved in both the toxicity of this metal and defence mechanisms in plants. In this work, the main Cd contamination sources, and the mechanisms involved in metal toxicity, hyperaccumulation and phytoextraction of Cd is reviewed.
