Correlations between concentrations (lw) of major persistent OCs and trophic level in the marine food web for Svalbard and Lancaster Sound Trophic level data were assigned based on Hobson and Welch (1992)
Sources Title (cont.) Trophic level of Greenland halibut and redfish were assumed to be 3.5, that is, higher than cod, but lower than seals. Data for invertebrates are from Hargrave (1994). Other results are from Annex Tables 6.A3, 6.A15, 6.A17, and 6.A20. Hobson, K.A. and H.E. Welch, 1992.
