Nitrate in water tied to colon cancer risk in some

27/11/2003 By Amy Norton NEW YORK (Reuters Health) - A contaminant found in drinking water may raise the risk of colon cancer in certain vulnerable groups of people, a study in Iowa suggests. The contaminant is nitrate, which can get into public water supplies from nitrogen-containing fertilizers used in agriculture, or from human or animal waste. U.S. regulations set a cap of 10 milligrams per liter (mg/L) on the amount of nitrate public water systems may allow in drinking water. In the new study, federal researchers found that for certain individuals, long-term exposure to drinking-water nitrate levels higher than 5 mg/L was associated with an increased risk of colon cancer. The at-risk groups were people with a relatively low vitamin C intake, a diet relatively high in meat, or a history of inflammatory bowel disease.
