摘要: Nitrate in drinking water may increase risk of colorectal cancer due to endogenous transformation into carcinogenic N‐nitroso compounds. Epidemiological studies are few and often challenged by their limited ability of estimating long‐term exposure on a detailed individual level. We exploited population‐based health register data, linked in time and space with longitudinal drinking water quality data, on an individual level to study the association between long‐term drinking water nitrate exposure and colorectal cancer (CRC) …
