A lifetime of consumption of bottled or tap water containing nitrates could be a risk factor for prostate cancer, a Spanish study has found.
The study, published in Environmental Health Perspectives on March 8, was led by the Barcelona Institute for Global Health (ISGlobal). It looks at the link between waterborne nitrate and trihalomethanes (THMs) and prostate cancer risk. Both nitrate and THMs are some of the most common contaminants in drinking water. Nitrate in drinking water is the result of fertilizers and manure from livestock farming washed by rainfall into rivers and aquifers, and THMs are byproducts of water disinfection.
