Hello, maybe it is not new, but give you more information for searching: http://superfund.ciesin.columbia.edu/sfund_files/imported/images/as_in_bang.gif

From: http://superfund.ciesin.columbia.edu/Rocklandwater/quality_arsenic

Abdullah, attached are some useful links about current state of tube well water in Bangladesh and nutritional status of youngsters who are exposed to and not exposed to arsenic. There is also a link to an article in Nature journal which reports that "The situation is especially dire in Bangladesh, where rice is the national staple and the water is naturally high in arsenic. Here as many as 100 million people suffer from acute arsenic poisoning from multiple sources".

Also attached is a useful paper that discusses strategies for remediation and removal of arsenic from drinking water and soils, and risk prediction of arsenic contamination, and a handbook written by the Environmental Protection Agency in the US which has some good information about mitigation strategies.

See also the final link:

http://pubs.rsc.org/en/content/articlehtml/2015/em/c4em00673a which has a map of arsenic concentrations for 2000.

Lastly there is a paper attached about 21 years of arsenic research in Bangladesh

I hope this helps.

Regards,

John
