Summary: We propose a novel approach for assessing environmental risks of discharges of produced water, taking into account explicit impact and probability. Our approach combines transport, fate, and toxicokinetic-toxicodynamic models within a super-individual framework, with a probabilistic element obtained from ensemble simulations. By considering location and species specificity, our approach addresses the dynamic nature of exposure and uptake of produced water components in the sea. Using a case study of early life stages of spawning haddock in the Barents Sea, we demonstrate the feasibility of conducting model-based risk assessments that capture the effects of natural variations in environmental conditions. We also discuss the benefits, limitations, and potential for further improvements of our approach.

Summary: The Arctic faces various environmental challenges, including the exploitation of mineral resources like nickel. Responsible development of nickel mining in the Arctic requires a risk assessment framework specific to the region. Further research is needed to assess the exposure and effects of nickel in aquatic Arctic ecosystems.

Summary: The rapid urbanization and industrialization in Zhuhai's coastal areas have led to severe heavy metal contamination. This study analyzed heavy metal levels in seawater, sediments, and organisms to assess distribution, enrichment, and ecological risk. Results showed that certain heavy metals exceeded standards in seawater, indicating anthropogenic pollution. Cd and Cu presented moderate environmental risks. The study emphasizes the importance of preserving biodiversity in ensuring the health and productivity of the coastal seawater ecosystem.

Summary: Redox-active species in Arctic lacustrine sediments have a significant role in regulating the carbon cycle. This study used voltammetric microelectrodes to measure the concentrations of redox-active species in the benthic porewaters of an oligotrophic Arctic lake. The results showed spatial heterogeneity in the abundance and distribution of these species, indicating the presence of both oxidizing and reducing microbial communities. The study also highlighted the variable distribution of redox-active substances in lacustrine and tundra environments, which can impact the carbon cycle.

Summary: The COVID-19 pandemic had an impact on the prevalence of Legionellosis, a type of pneumonia caused by the Legionella bacteria. Analysis of environmental surveys in tourist facilities conducted since 2019 showed an increase in Legionella contamination during the pandemic period. The most common risk factor for contamination was the temperature of circulated water.

Summary: Wetlands and freshwater bodies, such as lakes, are the primary natural sources of the greenhouse gas CH4 emission. A new study uses process-based biogeochemistry models to quantify methane emissions from both land and freshwater bodies in the pan-Arctic region. The results show that the total methane emissions from the pan-Arctic during 2000-2015 are estimated to be 36.46 +/- 1.02 Tg CH4 yr(-1), with wetlands contributing 21.69 +/- 0.59 Tg CH4 yr(-1) and freshwater bodies contributing 14.76 +/- 0.44 Tg CH4 yr(-1). The study helps to narrow the difference between previous estimates and identifies the key drivers of methane emissions from inland water systems.

Summary: In this study, species sensitivity distribution (SSD) was used to derive fresh-water sediment quality guidelines (SQGs) for four representative polycyclic aromatic hydrocarbons (PAHs). A linear relationship between SQGs and octanol-water partition coefficient (log KOW) was developed and applied to predict the SQGs of other twelve PAHs. The obtained SQGs were in the range of 0.46-1.79 mg/kg and showed good correlations with observed toxicities of sediments.

Summary: This study used species distribution models to analyze the distribution of fish species in relation to environmental variables. The results show that certain environmental factors have an impact on fish distribution. The study also found that the sensitivity and distribution of fish species are correlated with their breeding seasons, and identified a genetic barrier affecting species distribution. These findings are important for the conservation of endangered species and the development of conservation plans.

Summary: The trends and rates of Arctic snow cover extent (SCE) vary in different climate assessments due to various factors. Changes in time period, snow products, and methodologies contribute to the discrepancies in reported trends. While negative trends are consistent in spring, there is more uncertainty in autumn. This study investigated different factors that could impact SCE trends and found that the rate of change in May and June remains consistent despite improvements in snow products, and the most important factor affecting the calculated rate of change is the choice of climatological baselines.

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.
