Review Paper Arsenic induced oxidative stress and the role. A meeting on the health effects of arsenic (As), its modes of action, and areas in need of future research was held in Hunt Valley, Maryland, on 22-24 September 1997. Exposure to As in drinking water has been associated with the development of skin and internal cancers and noncarcinogenic effects such as diabetes, peripheral neuropathy, and Arsenic is a naturally occurring element that is widely distributed in the Earth’s crust. It is found in water, air, food, and soil. There are two general forms of arsenic — organic and inorganic. Inorganic arsenic, which affects the drinking water of millions of people worldwide, has been shown to be a human carcinogen. Scientists, pediatricians, and public health advocates are.
