The Strait of Georgia is a large, deep, fjord-like estuary on the southern coast of British Columbia which is subject to local and atmospheric inputs of persistent environmental contaminants. We measured 204 polychlorinated biphenyls (PCBs) and 61 po

Publikováno v: International Journal of Environmental Analytical Chemistry. 76:31-47

Harbor seal blubber samples were analyzed for PCDD/Fs and PCBs by splitting the initial extract into three aliquots and applying three different techniques for lipid removal (the first step of sample cleanup methodology for GC-HRMS analysis): gel per

Sources of organic matter to surficial sediments from the Scotian Shelf and Slope, Canada

Autor: Norman F. Crewe, Roger Pocklington, James D. Leonard

Publikováno v: Continental Shelf Research. 11:1069-1082

On the basis of chemical analyses of sediments sampled by grab and by box corer on the Scotian Shelf and Slope off Nova Scotia, Canada, an attempt is made to assign to source the organic matter (OM) found in surface and near-surface sediments. Concen
