Answer: D. West Bengal

• Arsenic (As) is an odorless and tasteless metalloid widely distributed in the earth’s crust. Elemental arsenic is a member of Group VA of the periodic table, with nitrogen, phosphorus, antimony and bismuth. It has an atomic number of 33 and an atomic mass of 74.91.
• Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tubewells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning of drinking water. The problem became serious health concern after mass poisoning of water in Bangladesh
• According to a report by the World Bank, more than 1,312 villages in West Bengal, India, near the Ganges River are detrimentally affected by arsenic contaminated groundwater.
• Arsenic in drinking water is absorbed through the intestine into the bloodstream through which it reaches the various organs. The human body normally gets rid of smaller amounts of arsenic through urine. However, if there are large amounts of arsenic, the remaining arsenic accumulates inside the body and can lead to adverse health effects. However, the mechanisms underlying the adverse health effects by arsenic are not completely known. The level of accumulated arsenic can be known by investigating nail and hair samples.
