A new study conducted in Bangladesh confirms that exposure to low to moderate amounts of arsenic in drinking water can impair lung function, comparable to decades of smoking tobacco. Dr. Habibul Ahsan, the author of the study from Chicago University, tells Healthy Lifestyle of VOA that high level arsenic is also reported in well water in China and India. He said there hasn’t been a study conducted in Tibet but mining sites can usually release arsenic into rivers. According to United States Environment Protection Agency (EPA), arsenic has been linked to cancer of the bladder, lungs, skin, kidney, nasal passages, liver, and prostate, as well as a number of non-cancer health problems. EPA has set the arsenic standard for drinking water at .010 parts per million. Dr. Lobsang Tenzin, the dean of Medical School of Varanasi University, said to Healthy Lifestyle program that arsenic containing materials are used in certain Tibetan and western medicines.
