The Montreal water treatment plant dumps 90 times the critical amount of certain estrogen products into the river. It only takes one nanogram (ng) of steroids per liter of water to disrupt the endocrinal system of fish and decrease their fertility.
These are the findings of Liza Viglino, postdoctoral student at the Universite de Montreal’s Department of Chemistry, at the NSERC Industrial Research Chair in Drinking Water Treatment and Distribution, who is under the supervision of Professors Sebastien Sauve and Michèle Prevost.
The presence and effects of estrogen residues on aquatic wildlife are well documented. However, this research is unique because it didn’t only consider natural hormones and those used in oral contraceptives - it also included products used in hormone therapy that is prescribed to menopausal women.
