Summary: This study investigated the tissue distribution, source, and trophic transfer of polycyclic aromatic hydrocarbons (PAHs) in East Asian finless porpoises, spotted seals, and minke whales. The levels of PAHs were relatively high in the marine mammals, with light molecular weight PAHs being the primary pollutants. While no tissue-specific distribution of PAHs congeners was found, species-specific PAHs concentration distribution was observed. It was found that petroleum and biomass combustion were the main sources of PAHs in finless porpoises, while the sources for seals and whales were more complex. Trophic level-associated biomagnification and biodilution were observed for different PAHs in the marine mammals.

Summary: The influence of vertical changes in water depth on the distribution of emerging pollutants and microbial food webs is not well understood. This study investigated the effects of vertical transition in water depth on environmental variables, antibiotics and antibiotic resistomes, and microbial community structures in estuary and marine ecosystems (0-50 m). The results showed that changes in water salinity were the most influential factor for fluoroquinolone and macrolide concentrations, while dissolved oxygen and turbidity were key influencers for sulfonamide and beta-lactam concentrations. Bacterial and eukaryotic diversity and niche breadth increased significantly with increasing water depth, and the ecosystem food web structure was more stable at the bottom depths. The abundance of antibiotic resistance genes (ARGs) was significantly higher at the surface depth compared to the middle and bottom depths.

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.
