Journal ArticleDOI
Ozone destruction and photochemical reactions at polar sunrise in the lower Arctic atmosphere
Leonard A. Barrie,Jan W. Bottenheim,Russell C. Schnell,Paul J. Crutzen,Paul J. Crutzen,R. A. Rasmussen +5 more
TL;DR: In this paper, the authors focus on recent ground-level observations from the Canadian baseline station at Alert (82.5° N, 62.3° W) and from aircraft that show that ozone destruction is occurring under the Arctic surface radiation inversion during March and April as the Sun rises.
Journal ArticleDOI
Arctic springtime depletion of mercury
W.H. Schroeder,Kurt G. Anlauf,Leonard A. Barrie,J. Y. Lu,Alexandra Steffen,D. Schneeberger,Torunn Berg +6 more
TL;DR: In this paper, the authors show that during the spring (April to early June) of 1995, there were frequent episodic depletions in mercury vapour concentrations in Arctic surface air.
Journal ArticleDOI
Contaminants in the Canadian Arctic: 5 years of progress in understanding sources, occurrence and pathways.

Stern,W.H. Schroeder,R. Wagemann,Mark B. Yunker +28 more
TL;DR: New knowledge developed under the NCP on the sources, occurrence and pathways of contaminants (organochlorines, Hg, Pb and Cd, PAHs, artificial radionuclides) are highlighted and compelling evidence for close connectivity between the global emission of contaminants from industrial and agricultural activities and the Arctic is provided.
Journal ArticleDOI
Arctic air pollution: An overview of current knowledge
TL;DR: In this paper, an estimate of the mean vertical profile of fine particle aerosol mass during March and April shows that, on average, pollution is concentrated in the lower 5 km of the atmosphere.
Journal ArticleDOI
Arctic contaminants : sources, occurrence and pathways
Leonard A. Barrie,D. J. Gregor,B. T. Hargrave,R. Lake,Derek C. G. Muir,R. Shearer,B. Tracey,Terry F. Bidleman +7 more
TL;DR: It is concluded that both the atmosphere and the ocean are important transport media for potentially toxic organic compounds in the northern polar region and even for the HCH substances, which are relatively easily measured and simple in composition compared to other synthetic organics.
