Pollution by arsenic

It is important to note that the information obtained by each of the above techniques is very useful for understanding the composition and behaviour of a particular sample. A particularly appropriate example was the investigation of ground-water pollution by arsenic in the Lower Ganga Plain of West Bengal in India and Bangladesh. At one location, arsenic concentration was clearly well above the safe drinking threshold, while at another in the close proximity it was not toxic [24]. In this...

The arsenic content exceeded maximum permissible concentration (M.P.C.) in practically all samples. In residential districts the arsenic content ranged from 4 to 10 M.P.C. The territory of Chapaevsk Chemical Fertilise Plant (CCFP) was greatly polluted by arsenic. The arsenic content in samples collected in this territory exceeded 15 M.P.C., and extremely high concentrations of arsenic (from 49 to 8500 M.P.C.) were registered in samples collected in the former lewisite-producing shop and near the place of WA bottling.
