ABSTRACT
Arsenic contamination of groundwater is a crucial water quality issue leading to various health exposures and sufferings in rural people of the world, particularly in Ganga-Meghna-Brahmaputra plain in Indian sub-continent. Arsenic is a notorious metalloid, which moves freely under the soil system, and also evenly percolates when comes into the nature while withdrawing groundwater. Cultivation of staple crops like paddy on these contaminated soils is one of the major routes for dietary exposure of arsenic. Arsenic uptake property of paddy plants was found to be dependent on the variety of cultivar rather than arsenic levels in groundwater or soil. Higher accumulation of arsenic has been observed in parboiled rice grain due to parboiling with arsenic-contaminated water.
