Table 4: Comparison of pollution levels between ringed and harbour seals in liver and blubber (ng/g lipid weight). Given is the mean and in brackets the standard deviation with the number of available samples for each pollutant group. sig diff: comparison between pollution levels within the ringed seals and harbour seals using a paired T-test. When comparing the pollution levels between ringed seals and harbour seals (rs:hs) for liver and blubber (last two columns) a GLM was used.
