This news is based on the following article: Vinceti M, Ballotari P, Steinmaus C, et al. Long-term mortality patterns in a residential cohort exposed to inorganic selenium in drinking water. Environ Res 2016; 150: 348-56. doi: 10.1016/j.envres.2016.06.009
Taking advantage of an historical exposure situation, this estimation of the impact on mortality of drinking water with a high selenium content adds to the existing knowledge on the subject. Selenium exposure may increase the risk of some site-specific cancers and neurodegenerative disease, although this needs confirmation.
