The Bengal Delta Plain formed by the sedimentation of three main rivers, Ganga, Brahmaputra and Meghna along with its several tributaries and distributaries have been found to contain significant amounts of arsenic in its groundwater and sediments due to hydrogeochemical, geological and biological factors which enhance the mobilisation of arsenic. India and Bangladesh have been severely affected by occurrences of vast number of arsenic toxicity-related diseases and deaths. The problem has gained a serious magnitude due to uptake, translocation and biomagnifications of arsenic in several food crops and vegetables. A number of associated factors including the type of plants affects the bioavailability, uptake and translocation of arsenic in crops, which has been discussed in the present communication. The present paper reviews the status of arsenic contamination, mobilisation and uptake in crops of India, Bangladesh specifically along with other arsenic-affected crops worldwide and related health impacts due to the consumption of arsenic laden water and food.
