Cadmium--influence on biochemical processes of the human organism.

Heavy metals are too well-known environmental pollutants of particularly dangerous effect to human health. Because of their wide usage in many industrial branches they are present everywhere in the air, water and soils. Food contamination by heavy elements is hard to avoid and it is a result of environmental contamination by dusts, industrial gases, sewage, waste and coal burning processes. One of the most harmful heavy metals, widely spread in nature is cadmium. Toxic cadmium action involves free oxygen generation and inactivation of protein containing cysteine residues with -SH groups. It influences many metabolic processes causing great damage in many organs. Cadmium can also interact with some essential elements leading to their homeostasis disorders.
