PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition
Mark B. Yunker,Robie W. Macdonald,Roxanne Vingarzan,Reginald H. Mitchell,Darcy Goyette,Stephanie Sylvestre +5 more
TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA
Journal ArticleDOI

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
A sediment and organic carbon budget for the Canadian Beaufort Shelf
TL;DR: In this paper, a mass balance for the Mackenzie Shelf of the Canadian Beaufort Sea is constructed for sediments, terrestrial organic carbon, and primary produced carbon, which is the only site for which a complete organic carbon budget can be attempted due to an extensive data base.
Journal ArticleDOI
Distribution and sources of organic biomarkers in arctic sediments from the Mackenzie River and Beaufort Shelf
TL;DR: The results of these investigations indicate that most lignin and cutin products originate from non-woody angiosperm vascular vegetation such as that present in the tundra as mentioned in this paper.
Journal ArticleDOI
The supply and preservation of ancient and modern components of organic carbon in the Canadian Beaufort Shelf of the Arctic Ocean
TL;DR: In this article, the provenance of organic matter in sediments from the Mackenzie River and Beaufort Shelf was investigated using the stable carbon and radiocarbon isotopic compositions of bulk organic matter and individual organic compounds, including lignin-derived phenols and lipid derived fatty acids.
