Summary: This study investigates the potential biological effects of an effluent discharge from an aluminium smelter into a Norwegian fjord using field transplanted mussels. The results show that mussels located closer to the smelter exhibit stronger biological responses, while mussels located further away also show significant biomarker responses suggesting the presence of a different contaminant source within the fjord.

Summary: The study investigates the community composition and seasonal development of large zooplankton in the northern Barents Sea. It reveals that temperature and bottom-depth are key factors shaping the zooplankton community, with distinct Atlantic and Arctic domains. The continental shelf exhibits an Arctic signature, characterized by a dominance of cold-water species, while the continental slope is dominated by the copepod Calanus hyperboreus. The study also highlights the seasonal shift in zooplankton feeding guilds and discusses the importance of food preferences in bridging periods of low primary production.

Summary: This study investigated the taxonomic composition and seasonal distribution of meroplankton in the Barents Sea, finding a high diversity of species yearround with abundance peaking in August and November. Different species dominated larval abundance and taxon diversity across the Polar Front, with higher total abundance in the south and greater taxon richness in the north. New knowledge on seasonal patterns of meroplanktonic species has implications for understanding environment-biotic interactions in the changing Arctic.

Summary: In port areas, identifying contamination sources is crucial for effective management. Biomonitoring provides information on the environmental impact of pollutants. However, differentiating natural biomarker variations from those induced by pollution can be challenging. This study aims to establish a baseline level for biochemical biomarkers in limpets collected from four North-Corsica port areas.

Summary: The study found that there were no significant differences in urinary antimicrobial peptide (AMPs) levels between older and younger adults, but older adults had lower levels of a specific AMP, hBD-2. This finding has implications for the potential use of urinary AMPs as diagnostic markers and will facilitate further exploration into the role of innate immunity in urinary tract infection susceptibility in older adults.

Summary: This study investigates the post mortem fluctuations in antioxidant response and carbohydrate metabolism in the liver of green turtles. The results show that changes in biochemical and molecular parameters following green turtle death are not immediate, and metabolism may remain relatively stable up to 24 hours after death. This has implications for the use of biomarkers in sea turtles for biomonitoring purposes.

Summary: In recent decades, the Barents Sea has warmed more than twice as fast as the rest of the Arctic in winter. This study reveals that enhanced clear-sky downward longwave radiation and increased total column water vapor are the main causes of the warming. Furthermore, the Barents oscillation, an atmospheric variability mode, has strongly contributed to the amplified warming through enhanced heat and moisture transport.

Summary: The study investigated the resting values of physiological oxidative stress in three cattle breeds, revealing that Limousin breed animals have higher intrinsic antioxidant defense systems. It also found a correlation between meat quality parameters and redox biomarkers, suggesting that specific antioxidant parameters in blood could be used as potential biomarkers to predict meat quality.

Summary: The finest fraction of PM2.5 carries genotoxic pollutants, such as some PAHs, which have been shown to have a significant correlation with adverse effects on the human respiratory system in epidemiological studies. Mutagenic seasonal variations were observed in a year-long study in nine sites in Northwestern Italy, with higher mutagenicity in winter and lower responses in summer. The study confirmed that environmental mixtures can be accurately assessed through physical-chemical analyzes combined with bioassays to evaluate synergistic and antagonistic effects in various pollution settings.

Summary: This study evaluated environmental quality at two sites in Sao Marcos Bay, Brazil, using a multibiomarker approach in the catfish Sciades herzbergii, detecting higher diffuse contaminations by trace elements and PAH in Porto Grande harbor compared to the reference area Ilha dos Caranguejos. Biological responses in catfish indicated adverse effects of pollutants through oxidative stress biomarkers and histopathological alterations, with contaminants correlated to the health status of the catfish S. herzbergii.

Summary: Assessing the population level effects of Arctic keystone species polar cod is crucial in response to potential oil spills. A study compared precautionary and refined approaches, showing significant differences in recovery durations for exposures with low concentrations and short durations. Understanding the consequences of precautionary assumptions can inform decisions on oil spill response and the need for more chronic toxicity testing.

Summary: Climate models predict prolonged ice-free periods in the Arctic waters in the next decade, allowing increased shipping activity and easier access to petroleum resources. Concerns arise over the biological effects of accidental petroleum release on key Arctic marine species such as polar cod. This study found that adult polar cod exposed to environmentally-relevant crude oil doses did not show significant effects on growth and survival, indicating their relative resilience to dietary crude oil exposure at tested doses.

Summary: A multidisciplinary programme in Norway has studied the environmental impacts of submarine tailing disposal (STD), providing new knowledge for global assessments and mitigation. Through detailed seafloor mapping, modelling, and toxicity tests, they have developed tools for monitoring and assessing the behavior of tailing particles and chemicals. Results suggest that full community recovery and normalization of metal leakage rates from sulfidic tailings may take several decades.

Summary: Fish embryos can be used as sentinels for environmental biomonitoring, but their fragility and seasonality limit their use. In this study, caged lumpfish eggs were successfully used for in situ biomonitoring of organic contaminants. The eggs showed high survival rates in different environments. Organic contaminants were effectively accumulated in eggs in polluted areas, but no evidence of toxicity was found in terms of larval morphometry.

Summary: The rise in offshore operations, maritime shipping, and tourism in northern latitudes increases the risk of oil spills to sub-Arctic and Arctic coastal environments. This study investigates the effects of oil exposure on the early life stages of capelin, an important fish species in the Barents Sea. The results suggest that capelin may be more resilient to crude oil exposure than other fish species.
