Summary
We report here on the presence of contaminants in the pelagic food chains in the lakes Mjøsa, Randsfjorden and Femunden and in supplementary material of fish from Tyrifjorden and Vansjø, sampled in 2015. Mercury and persistent organic pollutants (cVMS, PCBs, PBDEs, PFAS) were analyzed in samples of fish from all lakes, as well as pelagic crustaceans in Mjøsa. Among the key findings are that the siloxanes D5 and D6 show trophic magnification in Mjøsa and Randsfjorden and that PFTrA is the dominating PFAS in liver samples of fish.
