Arsenic Bioaccumulation in Rice and Vegetables and subsequent transmission in food chain

Arsenic is a metalloid of great environmental concern because of its highly toxic nature and wide abundance. Arsenic contamination in groundwater has been reported in Bangladesh, India, China, Taiwan, Vietnam, USA, Argentina, Chile and Mexico. The use of arsenic contaminated groundwater for irrigation purpose in crop fields elevates arsenic concentration in surface soil and in the plants grown in arsenic contaminated areas. The arsenic concentrations in the edible parts of a plant depend on the availability of the soil arsenic and the accumulation and translocation ability of a plant.
