Monitoring of environmental contaminants in air and precipitation. Annual report 2017.
This monitoring report presents data from 2017 and time-trends for the Norwegian programme for Long-range atmospheric transported contaminants. The results cover 180 organic compounds and 11 heavy metals. The organic contaminants include regulated persistent organic pollutants (POPs) as
well as POP-like contaminants not yet subjected to international regulations. Five groups of new POP-like contaminants were included for the first time in 2017.

This report studies the distribution and fate of contaminants such as mercury (Hg), cyclic volatile methylated siloxanes (cVMS: D4, D5, D6), brominated flame retardants (BFR, PBDEs), alkylphenols, organic phosphorous flame retardants (oPFR), poly- and perfluorated alkyl substances (PFAS), new brominated flame retardants (nBFR) and UV-chemicals. Samples of the pelagic food web of Lake Mjøsa (zooplankton, Mysis, vendace, European smelt and brown trout) and the top predator brown trout in Lake Femunden are studied. Results are compared to environmental quality standards (EQS) and the time trends for major contaminants are studied.

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 2019. In this report, the status of contamination in the food web, trends and biomagnification potential of various environmental contaminants is discussed.

Monitoring of environmental contaminants in freshwater food webs (MILFERSK) 2022
Samples of a benthic food chain in Lake Mjøsa have been collected, and the concentrations of emerging contaminants such as
Siloxanes, PFAS, UV-compounds, Quaternary Ammonium Compounds, Musks, Benzothiazoles and Chlorinated paraffins in
addition to legacy contaminants such as Mercury, other Metals and PBDEs have been determined. For comparison, samples of
the top predator brown trout have been collected and analysed from Lake Femunden, a rural counterpart to the more urban
Lake Mjøsa.

Monitoring of environmental contaminants in freshwater food webs (MILFERSK), 2023
This report presents data from the third year of a 5-year period of the MILFERSK program. In 2023 the monitoring program reports on the sampling and analyses of the pelagic food chain in Lake Mjøsa, with the following sample types: zooplankton, Mysis, E. smelt, vendace, and brown trout, in addition to brown trout from Lake Femunden. A total of 205 single compounds/isomers were determined, and frequent detections were found of specific PFAS, PBDEs, Hg and siloxanes through the food chain with biomagnifying properties. Some contaminants, such as octocrylene is found in higher concentrations in the lower trophic levels. A slight downwards trend is observed from 2014 – 2023 for PFOS in Lake Mjøsa. We also observe a lower length adjusted mercury concentration for brown trout in Lake Mjøsa for the period 2014 to 2023, compared to the 9 years prior (2006 – 2014).

This report presents data from the fourth year of a five-year period of the MILFERSK program. In 2024, the monitoring program focused on the sampling and analysis of the benthic food chain in Lake Mjøsa, encompassing the following sample types: Chironomids, Ruffe, Perch, Pike and the stomach contents of ruffe. Additionally, brown trout from the pelagic zone in Lake Mjøsa were collected and analyzed, with the contaminant levels compared to samples of brown trout from the reference lake, Femunden. The concentrations of 175 individual compounds/isomers were determined, with frequent detections of specific per- and polyfluoroalkyl substances (PFAS), polybrominated diphenyl ethers (PBDEs), mercury (Hg), and siloxanes exhibiting biomagnifying properties throughout the food chain. Certain contaminants, such as quaternary ammonium compounds, were found in higher concentrations in sediment and lower trophic levels. Concentrations of chlorinated paraffins (CPs), particularly medium-chain chlorinated paraffins (MCCPs) were higher in chironomids, ruffe, and the livers of perch and pike, compared to levels observed in 2021 and 2022, with an increase up the food chain in 2024. A slight downward trend in perfluorooctane sulfonate (PFOS) concentrations was observed in Lake Mjøsa from 2014 – 2024. Additionally, a lower length-adjusted mercury concentration was noted for brown trout in Lake Mjøsa during the period from 2015 to 2024, compared to the preceding nine years (2006 – 2014).
