The Journal of Exposure Science and Environmental Epidemiology last week revealed the findings of a 2016 pilot study that measured pregnant women's exposure to environmental contaminants in northeastern British Columbia, an area of intensive natural-gas production through hydraulic fracturing (fracking). The study, directed by Marc-André Verner, a professor at the School of Public Health (ESPUM) of Université de Montréal (UdeM), showed that the women had higher concentrations of some metals, especially barium, aluminium, strontium and manganese, in their hair and urine compared to the general population.
“These results are of concern because a previous study showed that relatively high concentrations of barium, aluminium, strontium and manganese are found in rock samples from B.C.'s Montney Formation, where natural gas is extracted via fracking," said Élyse Caron-Beaudoin, a post-doctoral researcher at EPSUM and the study’s lead author. "In addition, recent studies analyzing wastewater from fracking generally have shown higher concentrations of the same metals."
“It's impossible to say with certainty whether fracking caused the women’s exposure to these metals," she added, "but our study does provide further evidence that this could be the case."
