Abstract
In this article, lead (Pb) content in snow of the early 1990s' from the Arctic, Antarctica and the Tibetan Plateau will be discussed, based on measurements along 1990 International Trans-Antarctic Expedition route, three glaciers on Tibetan Plateau as well as snowpack over the Canadian and central Arctic. Author C.D. Xiao and colleagues seek to highlight the human influence on atmosphere over the most remote regions and the upper troposphere. The distribution of Pb over northern Canada indicates that the Northwest Territory (NWT) of Canada is not an efficient channel for Pb transport to central Arctic. Pb concentrations display a decreasing trend from Ely to NWT Canada.
