Abstract

Arsenic is widely distributed in the soil, water, air and all living matters. Presently arsenic pollution through food-chain contamination is a major health concern worldwide. It poses menacing damage compared to arsenic pollution in drinking water. Arsenic may occur in both inorganic and organic forms. Arsenate can compete with phosphate within the plant cells disturbing the energy flow in the cell. Arsenite reacts with a number of enzymes and tissue proteins that can cause inhibition of cellular function and finally death. Arsenate is taken up by plants via phosphate uptake system, while arsenite is taken up through water channels or aquaporins in the roots. Arsenic is then transported from root to leaves through xylem. However, different forms of arsenic have different translocation efficiencies.
