Article Synopsis
- The study focuses on identifying and prioritizing water bodies with high levels of human-made chemicals, which is essential for environmental monitoring but challenging due to various factors.
- Researchers introduce a new method using passive sampling data collected over ten years to analyze hydrophobic organic contaminants (HOCs) in surface waters across Europe.
- The findings highlight that concentrations of hexachlorobenzene (HCB) and pentachlorobenzene (PeCB) in water can indicate contamination levels, and using these as benchmarks, researchers can assess the presence of other HOCs in the environment.
The banning of organotin biocides, such as tributyltin (TBT), from use in marine antifouling paints is now leading to reproductive health recovery in marine gastropod populations all over the world. TBT induces so-called imposex (superimposition of male sexual characters onto females) in certain marine gastropods, such as the common dogwhelk Nucella lapillus. In this publication, the results of the Norwegian TBT and imposex monitoring in N.

The ecological impact of MP pollution is still unknown, thus there is an urgent need for more knowledge. One key task is to identify species suitable as sentinels for monitoring in key eco-compartments, such as coastal waters.

- The blue mussel (Mytilus spp.) is recognized as an effective bioindicator for tracking coastal water pollution, utilized in various mussel watch programs.
- This review addresses the suitability of Mytilus spp. in environmental monitoring, including their uptake of key pollutants and recent trends in monitoring practices in Norway.
- It also highlights challenges and future research areas in pollution monitoring related to environmental quality standards, confounding factors like microplastics, and the impacts of climate change.
Article Synopsis
- Mercury levels in Atlantic cod from the Inner Oslofjord have been monitored since 1984 and showed significant increases until 2014.
- The rise in mercury concentrations correlated with an increase in the size of the sampled cod, likely due to low recruitment of younger fish since the early 2000s.
- When adjusting the mercury data to account for cod length, no significant short-term trend in mercury levels was found, suggesting that the earlier increases were largely due to sampling larger fish rather than a general rise in mercury levels.
The Sørfjord has a long history of agriculture and industry, and environmental monitoring has been conducted for decades, comprising analyses of contaminants in mussel, fish and sediments. DDT was used as an insecticide in orchards surrounding the fjord between World War II and 1970. Since the early 1990 s, elevated concentrations of DDT were found in mussels and fish.

The environmental monitoring has comprised analyses of different contaminants in sea water, mussel, fish, seaweed and sediments. Measurements of polychlorinated biphenyls (PCBs) in blue mussels (Mytilus edulis) some 17 years ago indicated a local source.

The indicator organisms analysed as bulked/individual samples were cod (Gadus morhua, n approximately 1170; n approximately 240 for organochlorines), dab (Limanda limanda, n approximately 75), plaice (Pleuronectes platessa, n approximately 55) lemon sole (Microstomus kitt, n approximately 13). and blue mussels (Mytilus edulis, n approximately 200) collected between 1991-2000.
