In a study published in the July 24 online edition of the journal Nature Climate Change, researchers led by the Air Quality Research Division of Environment Canada examined concentrations of so-called “persistent organic pollutants” (POPs) at two Arctic monitoring stations in Svalbard, Norway and Canada.
