摘要：

Measurements of the ionic composition of snow from interior Alaska (latitude 65-degrees-N) show clearly that the snowpack is very clean, in spite of the fact that the atmosphere is rather contaminated from general Arctic-wide air pollution known as ''Arctic haze''. This dichotomy suggests a lower than world-average value for the removal rate of aged air contaminants in the Arctic. A model, based on general principles of physics, gives results consistent with the observations of lowered-rate of removal of Arctic contaminants.
