Peace River Valley, in northeastern British Columbia, has become known in recent years as a place of hydraulic fracturing for natural gas – "fracking," as it's commonly called. What are the health impacts related to living near fracking sites where contaminants, including volatile organic compounds, are released? To try to answer that question, Élyse Caron-Beaudoin, a postdoctoral researcher at the Université de Montréal Public Health Research Institute, studied a group of pregnant women who live in the area. Her results were published this week in Environment International.
