Antibiotics, antimicrobials and antifungals in waterways

Detrimental effects of anti-infectives on aquatic microbiota are possible

Montreal, June 9, 2009 – Antibiotics, antimicrobials and antifungals are seeping into the waterways of North America, Europe and East Asia, according to an investigation published in the peer-reviewed journal Environmental Health Perspectives (EHP). Authored by Université de Montréal and Environment Canada researchers, the review found that consumption of anti-infectives for human and agriculture use contributes to their release into the environment and even into drinking water.

"Anti-infectives are constantly discharged, at trace levels, in natural waters near urban centres and agricultural areas," says senior author Sébastien Sauvé, a Université de Montréal professor of environmental analytical chemistry. "Their potential contribution to the spread of anti-infective resistance in bacteria and other effects on aquatic biota is a cause for concern."
