Extensive evidence of elevated arsenic in the food chain, mainly rice, wheat and vegetables exists.

This presentation deals with the problem of arsenic contaminated aquifers in the Gangetic belt of Bihar and the failure of the state government in tackling the crisis and calls for the establishment of a centralized knowledge & research hub with an understanding of the regional peculiarities to mitigate the crisis.

It traces the origin of arsenic crisis to the switch from use of surface water to groundwater. The health impacts of arsenic poisoning and the factors that aggravate arsenicosis are explained. A total of sixteen districts (fifty-seven blocks) in Bihar are affected by high levels of arsenic in groundwater, in trivalent form, which is a more toxic form of arsenic.
