According to a news report April 19, 2001, a team of EPA scientists at EPA's Office of Research and Development laboratory in North Carolina have discovered a possible, direct link to DNA damage caused by arsenic compounds. The research demonstrates a human cell's own metabolic responses to arsenic exposure produce compounds that cause genetic damage.
A National Academy of Sciences (NAS) report says the US Environmental Protection Agency (EPA) has greatly underestimated the cancer risks of arsenic in drinking water, according to EPA officials, WaterTech online, 12 September 2001
