ABSTRACT
Arsenic contamination is a worldwide problem and has become one of the most severe threats to the health of millions of humans and other organisms, even to global sustainability due to its carcinogenicity. Long-term exposure of arsenic may increase the risk of skin, liver, bladder, and lung cancers. It is reported that over 137 million people in more than 70 countries are probably affected by arsenic contamination from drinking water [1]. Arsenicosis is prevalent in certain areas of many countries, including India, Bangladesh, Mongolia, Taiwan, Argentina, and Chile. The two worst affected areas in the world are Bangladesh and West Bengal, India. According to the World Health Organization (WHO), in both of these areas, the groundwater arsenic concentrations were above of 50 μg/L, some even reaching 3400 μg/L [2].
