Summary: The fractionation behaviors of Cu and Zn isotopes were studied in groundwater contaminated with petroleum and treated by oxidation. The study assessed the isotopes of Cu, Zn, SSO4, and H2O2 in wells contaminated with total petroleum hydrocarbons (TPH) and treated with H2O2 in 2021 and 2022. The results suggested the occurrence of sulfate reduction and precipitation of Cu sulfides, while the Zn isotopic fingerprint of sulfide precipitation may have been masked by sorption. The use of Cu isotopes in redox reactions proved advantageous due to the wider range of Cu isotopes.

Summary: Expansion of land-based systems in fish farms raises the level of metabolic carbon dioxide (CO2) in the water. High CO2 can increase bone mineralization in Atlantic salmon. Low dietary phosphorus (P) can halt bone mineralization. This study shows that high CO2 can counteract reduced bone mineralization imposed by low dietary P intake.

Summary: This study revealed that the addition of sulfide (S2-) enhanced the coupling of denitrification with sulfide oxidation, leading to a shift in nitrate reduction pathways in freshwater lake sediments. The enrichment of Thiobacillus, a sulfide-oxidizing denitrifier, was found to play a key role in driving sulfide-driven denitrification, with differences observed in lakes with varying inherent organic carbon and sulfate levels. Additionally, internal sulfate release was seen to promote cooperation between sulfide-oxidizing denitrifiers and sulfate reducers in freshwater environments.

Summary: The genetic introgression of farmed salmon into wild populations can harm genetic integrity. To address this issue, researchers have identified the potential role of the Piwil1 protein in germ cell survival in Atlantic salmon. By inducing mutations in Piwil1 using CRISPR-Cas9, they observed a mosaic pattern of mutations in the F0 generation of salmon. These mutants still carried germ cells but exhibited partial germ cell loss and delays in spermatogenesis. Further analysis revealed the importance of the N domain of Piwil1 for its function. By generating F1 fish with different combinations of mutated alleles, they found that complete loss of Piwil1 led to the absence of germ cells, while heterozygous fish displayed an intermediate phenotype with a higher ratio of somatic cells to germ cells.

Summary: The reduction of sulfate to hydrogen sulfide by microbes is highly undesirable in industrial settings. This study demonstrates that Desulfovibrio desulfuricans can be coated with locally generated metal nanoparticles, with individual cells carrying more than 100 times their mass of palladium metal. Moreover, the study reveals the effect of metal coating on metabolism and replication, with bacteria unable to reduce sulfate to sulfide beyond a specific threshold. These findings present a foundation for a novel means of modulating the activity of sulfate-reducing bacteria.

Summary: This study presents a new technology that combines sulfate reduction with simultaneous nitrification and autotrophic denitrification. The integrated process effectively removes nitrogen and organics from saline wastewater with a low COD/N ratio, while minimizing the energy consumption, footprint, and sludge yield. By integrating an anaerobic membrane bioreactor (AnMBR) with a membrane aerated biofilm reactor (MABR), highly efficient sulfate reduction, autotrophic denitrification, and nitrification are achieved. The separate operation of the MABR achieves over 90% total nitrogen removal when the N/S ratio is controlled at 0.4 gN/gS.

Summary: This study investigates the coupling of bacterial sulfate reduction (BSR) and organic carbon (OC) mineralization in seasonally hypoxic reservoirs. The results show that the water chemistry and microbial community are influenced by seasonal variations and water column stability, leading to changes in the diversity and activity of sulfate-reducing bacteria (SRB) and the fractionation of sulfur isotopes. The study also suggests that the reductive dissolution of iron and manganese oxides may be stimulated by the sulfide produced during BSR.

Summary: The managed realignment of the Gyldensteen Coastal Lagoon after flooding agricultural land resulted in a succession of macroalgae and benthic cyanobacteria over 5 years. A bloom of green macroalgae dominated by Cladophora spp. occurred in the first year, followed by increased species richness and a cyanobacterial bloom controlled by declining nitrogen concentrations in the water. After 5 years, the lagoon reached a tipping point where changes in nitrogen and phosphorus ratios influenced the balance between cyanobacteria blooms and high macroalgal species richness.

Summary: In this study, a short-term field sampling was conducted, complemented with time integrating stable isotope analysis, to holistically investigate the status and ecological interactions in a remote NE Atlantic Zostera marina meadow. The study found high nutrient water concentrations, large biomass of fast-growing, ephemeral macroalgae, low abundance and biodiversity of epifauna, and a food web with thornback ray as intermediate and cod as top predator. The results indicated that the Finnoya Zostera ecosystem is eutrophicated. The study concluded that bottom-up regulation is a predominant driver of change since top-down regulation is generally weak in low density and exposed Zostera ecosystems such as Finnoya.

Summary: Vegetated coastal and marine habitats in the Nordic region, such as salt marshes, eelgrass meadows, and brown macroalgae, play a crucial role in the storage of organic carbon (Blue Carbon - BC), coastal protection, biodiversity, and water quality. The existing knowledge on Nordic BC habitats is incomplete, but indicates substantial BC stocks. However, more research is needed to provide a robust estimate of Nordic BC stocks and sequestration rates, as well as improved coordination at national and regional levels.

Summary: The study aimed to understand the mechanisms behind the impact of nutrient enrichment on the interactions between a subtidal macroalgae community and the sea urchin Paracentrotus lividus. The results showed that nutrient input led to changes in the macroalgal community, with a shift to turf-forming species and an increase in invasive algae. Stable isotope analysis revealed nitrogen enrichment in the macroalgae and its transfer to P. lividus. Metabolomic analysis indicated stress in P. lividus at an intermediate distance from aquaculture. The combination of traditional ecology and omics technology can uncover both sublethal effects of nutrient loading and species interactions.

Summary: Coastal ecosystem functioning relies on foundation species that engage in positive interactions to mitigate environmental stress. Seagrasses are important foundation species in coastal zones, but they are rapidly declining due to global change-related stress. Recent studies have shown that seagrasses can engage in a mutualistic relationship with lucinid bivalves that alleviate sulphide toxicity. However, the generality and importance of this mutualism under different environmental conditions are still unknown.

Summary: Manipulating the decomposition of agricultural straws by white-rot fungi can enhance the antialgal efficiency and lead to the discovery of new allelochemicals called sphingosines. These sphingosines exhibit superior antialgal capability, with lower effective concentration compared to other known antialgal chemicals. The growth suppression of algae is triggered by programmed cell death, dysfunction of photosystem and antioxidant system, and disruption of CO2 assimilation and light absorption.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
