Quizplus · Accepted Answer

The high PCB concentrations in the bodies of native peoples living in the Canadian Arctic are primarily due to the long-range transport of airborne pollutants. PCBs, which are industrial chemicals, can travel long distances through the atmosphere from their sources of use or disposal, eventually depositing in colder regions like the Arctic. This phenomenon, known as global distillation or the grasshopper effect, leads to the accumulation of persistent organic pollutants (POPs) in the Arctic environment, impacting local wildlife and the indigenous peoples who rely on them for food.
