Arsenic is not just a Bangladesh problem — it can be found in drinking water supplies around the world. Maine, Massachusetts, Texas, and half a dozen other states have all had arsenic contamination problems, says Joseph Graziano, a professor of environmental health sciences and pharmacology at Columbia University.

Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the "largest mass poisoning of a population in history." An estimated 60 million people were unknowingly drinking groundwater containing dangerous concentrations of naturally occurring As.

At present arsenic contamination in drinking water is one of the severe problems of Bangladesh. It is estimated that of the 121 million inhabitants of Bangladesh 35 million to 77 million are at the risk of arsenic. They suffer immensely. 3.

We know that microbes in the mouse gut help convert almost all arsenic into DMA. Se hela listan på who.int Neither pyrite oxidation nor competitive exchange with fertilizer phosphate contribute to arsenic pollution. The most intense reduction and so severest pollution is driven by microbial degradation of buried deposits of peat. Concentrations of ammonium up to 23 mg L −1 come from microbial fermentation of buried peat and organic waste in latrines.

It may be mentioned that Bangladesh obtain table salt from solar drying of sea water and consequently increase pollution of sea water shall create a serious national health hazard situation. About 20,000 fishermen became jobless at Rangonia, Boalkhali and Anwara Upazila due to water pollution (Dept. of Environment, 1988).
