Study: Atrazine poses no cancer risk in drinking water

A new report in the March 2013 issue of European Journal of Cancer Prevention states atrazine appears to be a good candidate for a category of herbicides with a probable absence of cancer risk. The authors, Boffetta et. al, recommend that atrazine continue to be treated for regulatory and public health purposes as an agent unlikely to pose a cancer risk to humans. They reviewed reports from the U.S. Environmental Protection Agency (EPA) and the July 2011 EPA Scientific Advisory Panel to determine whether epidemiologic studies suggested a link between atrazine and specific cancers. A weight-of-evidence analysis concluded "that there is no causal association between atrazine and cancer.

These findings are consistent with the Agricultural Health Study, a large multiyear study sponsored by the National Cancer Institute, the National Institute of Environmental Health Sciences as well as EPA. Other government agencies and independent organizations including the World Health Organization and regulatory agencies in the United Kingdom, Canada, and Australia have reached similar conclusions.
