Abstract
Shallow tube well water is highly contaminated with arsenic (As) in arsenic affected area in West Bengal. The results of a total 25 samples in that area showed increased level of arsenic contents in soil (range: 9.671 to 14.964 ppm, n=5), tube well water (range: 0.171 to 0.497 ppm, n=5), paddy plants (range: 0.994 to 3.059 ppm, n=5) and the concentration of cow milk (mean: 0.156 ±0.009 ppm) was 12 times higher than the healthy cattle (0.013 ± 0.011 ppm) from non affected area. Extensive withdrawal of arsenic contaminated ground water contaminates surface soils and plants and causes hazardous effect on animals and arsenic contaminated milk would be dangerous for human consumption through food chain.
