Final answer:
The statement that the Arctic region has been free of air pollution is false; this region is affected by pollutants from various sources, including long-range transport and local industrial activities.
Step-by-step explanation:
The statement that the Arctic region has been free of air pollution is false. Air pollution in the Arctic comes from various sources, including long-range transport of pollutants from industrial areas,
local mining, and drilling operations. The melting of the ice also releases trapped gases such as carbon monoxide, which can accelerate global warming. Therefore, despite the remote and sparsely populated nature of the Arctic, it is not free from the effects of air pollution and the associated climate impacts.
