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. All data are a part subject of a publication containing method details, full QA/QC, interpretation and conclusions: Facciola, N., Pedro, S., Houde, M., Fisk, A. T., Ferguson, S.
