This study investigated short-chain (C10-13) chlorinated paraffins (SCCP) in an Arctic marine food web. In zooplankton, fishes and ringed seals from western Hudson Bay, Canada, SCCP concentrations ranged from 38.3 to 687 ng g-1 lipid weight. Monte Carlo-simulated trophic-adjusted biomagnification factors of individual SCCP congeners ranged from 0.07- 0.55 for small pelagic fishes-to-seals. Despite relatively high concentrations in fishes, biomagnification of SCCPs within this food web appears limited.

Supplemental Information
The Northern Contaminants Program (NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DB
A.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples. Early studies found a wide variety of substances, many of which had no Arctic or Canadian sources, but which were, nevertheless, reaching unexpectedly high levels in the Arctic ecosystem.
The Canadian Cryospheric Information Network (CCIN, https://www.ccin.ca/) and the Polar Data Catalogue (PDC, https://polardata.ca/) have been developed over the past two decades through collaborative partnerships between the University of Waterloo and numerous government, university, and private organizations to provide the data and information management infrastructure for the Canadian cryospheric community. The PDC is one of Canada’s primary online sources for data and information about the Arctic and is Canada's National Antarctica Data Centre.
