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, aluminum, strontium and manganese, in their hair and urine compared to the general population.
