Sammendrag:
This program, «Monitoring of environmental contaminants in freshwater ecosystems and single species in large Norwegian lakes”, has covered sampling and determination of environmental contaminants by analyses of organisms in an aquatic, pelagic food web of Lake Mjøsa, and in the top predator in Lake Femunden. Samples of different trophic levels, from epipelagic zooplankton to the top predator brown trout, were collected during the late stages of the growth season in 2020. In this report, the status of contamination in the food web, trends and biomagnification potential of various environmental contaminants is discussed.
