Summary: The study found that N2O consumption rates are high in the seasonally anoxic environment of Chesapeake Bay, but generally undetectable in oxygenated waters. However, when the oxygen concentration was reduced in oxygenated samples, N2O consumption rates increased significantly, indicating the potential for N2O consumption in oxygenated environments. These new observations provide insights into N2O cycling processes and can be used to improve the modeling of N2O flux in estuaries.

Summary: This study evaluates the use of constructed wetland-microbial fuel cells (CW-MFC) as a sustainable solution for reducing greenhouse gas (GHG) emissions. The results show that carbon fiber felt (CFF) exhibits the lowest methane and nitrous oxide emissions among the selected cathode materials. Adjusting the influent pH from acidic to alkaline also reduces GHG emissions. However, the addition of nickel inhibits GHG emissions but decreases electricity generation. Additionally, a low carbon-to-nitrogen ratio reduces methane emissions, while a high ratio effectively inhibits nitrous oxide emissions.

Summary: This study investigated the temporal and spatial patterns of antibiotic resistance genes (ARGs) in estuarine environments in China and their relationships with environmental constraints using metagenomics. The results showed that ARG abundance, richness, and diversity were higher in the dry season and increased with latitude. Human activities and climatic variables were identified as the most important factors influencing the prevalence of ARGs, with temperature being the most significant climate variable. The findings suggest that ARG dynamics in estuarine environments are co-driven by anthropogenic activities and climate.

Summary: This study reveals the effects of crab bioturbation on N2O emissions in coastal wetlands and their underlying molecular mechanisms. The presence of crabs significantly increases N2O emissions, positively correlated with the intensity of crab bioturbation. Hydroxylamine oxidation and bacterial denitrification are the dominant pathways for N2O production, and changes in microbial communities may drive the increase in N2O emissions in crab-disturbed habitats.

Summary: Both traditional petroleum-based and emerging biodegradable microplastics promote N2O production in sediment, but the pathways vary. Biodegradable polylactic acid (PLA) microplastics have a greater promotion of N2O production compared to petroleum-based polyvinyl chloride (PVC) and polyethylene (PE), with PLA promoting it through nitrifier nitrification and heterotrophic denitrification, PE through nitrifier denitrification and heterotrophic denitrification, and PVC through nitrifier nitrification. Different nitrogen cycling microbes' response to microplastics leads to the differences in N2O increase pathways, with nitrifying bacteria significantly enriched in all microplastic treatments, while part of denitrifying bacteria significantly enriched in treatments containing PLA and PE microplastics.

Summary: This study investigated the spatial changes in gross nitrogen transformation rates and related functional gene abundances in the intertidal zone of the Yangtze Estuary. The results suggest that gross nitrogen transformation rates vary significantly in estuarine and intertidal wetlands, with higher rates observed in freshwater and low-salinity areas. Sedimentary total organic carbon, nitrite, ferrous iron, and microbial functional gene abundances jointly mediate the gross nitrogen transformations. This research provides a better understanding of nitrogen cycling and management strategies in estuarine and coastal environments.

Summary: The deposition of PAHs has significant impacts on Earth's surface system and human health. However, the understanding of PAHs' deposition in highly urbanized areas is limited due to data limitations and low resolution of current models. This research establishes a deposition map of PAHs in Shanghai, China, with a resolution of 2 x 2 km. The results show that the downtown area of Shanghai has the highest PAHs deposition, which is 4.3 times higher than that in the outlying areas. Wet deposition dominates in Shanghai, accounting for 77% of the area and 62% of the total deposition. The deposition of PAHs follows a seasonal trend of summer>fall>spring>winter, similar to rainfall patterns. Built-up land and human activities are identified as key driving factors of PAHs' deposition in Shanghai.

Summary: Tidal-induced shifts of n-DAMO activity and associated contribution to mitigating CH4 in intertidal wetlands were studied. The study found that the wetting-drying events caused by tidal cycling had significant effects on the abundance and activity of n-DAMO microbial communities. The presence of n-DAMO bacteria and archaea and their higher biodiversity under reflooded conditions were also observed. Structural equation modeling and correlation analysis indicated that n-DAMO activity was influenced by microbial abundance, substrate availability, and salt accumulation in sediment. This study provides valuable insights into accurately estimating CH4 emissions from intertidal wetlands under different tidal scenarios.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
