ARSENIC Arsenic was evaluated in the first and third volumes of Drinking Water and Health (National Research Council, 1977a, pp.

Investigators have gathered and examined data from a variety of sources, including patients given prescribed medicinal arsenic compounds, several occupationally exposed groups, and populations exposed to high levels of arsenic in drinking water supplies (Arguello et al., 1939~. Although arsenic exposure has been associated primarily with skin cancer, associations with other cancers, cardiovascular dysfunctions, and a peripheral vascular disorder known as "blackfoot" disease have also been found.

In three epidemiological studies conducted in the United States, investigators found no positive relationship between high levels of arsenic in drinking water and adverse health effects. More than 200 residents of Fairbanks, Alaska, exposed to drinking water containing mean arsenic levels of 224 ppb displayed no increases in skin disorders, although the longest exposure in the study population was only 10 years (Harrington et al., 1978~.

First, it is always of great value when epidemiological associations are supported with animal studies; however, animal studies have generally not indicated that arsenic is carcinogenic (International Agency for Research on Cancer, 1980; U.S. Environmental Protection Agency, 1979~.

Furthermore, only 0.4~o of the drinking water samples taken from public water supplies in the United States have exceeded a total arsenic concentration of 0.01 mg/liter (National Research Council, 1980~. This finding is in sharp contrast to the average concentration of 0.4 mg/liter (400 ppb)
