Contaminant emissions, transport and deposition in the Arctic
An illustration of the interplay between a) contaminant emissions distribution for sulfur dioxide and b) frequency of atmospheric south-to-north transport, yielding c) a net annual input of sulfur to the Arctic as a function of longitude that favors Euras
that favors Eurasian sources in the winter half of the year. This contaminant has a one-hop pathway in contrast to more volatile persistent organochlorines, PAHs, and mercury.
