Summary: The study demonstrated that acidification stimulates N2O release from estuarine sediments, mainly mediated by bacterial denitrification; in neutral environments, N2O production is dominated by fungi. The contribution of chemo-denitrification to N2O production cannot be ignored, but is not significantly affected by acidification.

Summary: Dam construction is a major disturbance in aquatic ecosystems, leading to increased N2O emissions. This study investigated the effects of dams on N2O producers and reducers in river sediments. The results showed that sediments in the transitional zone of dammed rivers are critical for N2O emission potential, with different rates in winter and summer. The dominant N2O-producing microorganisms were nirS-harboring bacteria, while N2O-reducing bacteria harbored nosZ I. The study also revealed the importance of nosZ II-containing microbial groups in reducing N2O emissions from dammed river sediments.

Summary: A study of sediment samples from Arasalar River reveals that the predominant sediment composition is silty sand and sand silty. The presence of shell fragments is proportional to the calcium carbonate content, while organic matter originates from riverine and coastal input. Heavy metals in the sediments originate from both geogenic and anthropogenic sources. The pollution indices categorize the area as under polluted, low to moderate polluted, and low potential environmental risk. Continuous monitoring and guidance are necessary to prevent pollution from nearby agriculture and industrial activities.

Summary: This study examines N2O emissions in the Yangtze River basin and finds a decrease largely due to human-driven nitrogen control. Urban rivers have higher N2O emissions compared to rural areas, and the relationship between N2O emissions and nitrogen discharge intensity is nonlinear. The findings suggest that different nitrogen control measures are needed for urban and rural areas to achieve greater emission reductions.

Summary: This study investigates the riverine N2O emissions in suburban, urban, and rural sections of the Qinhuai River in Southeastern China. The results show that suburban agriculture increases the nitrogen concentration in the river, but leads to lower indirect N2O emissions compared to urban rivers. The study suggests that high dissolved organic carbon and low dissolved oxygen contribute to the limited indirect N2O fluxes in suburban agricultural rivers.

Summary: The N2O emission rate in the Changjiang River network is negatively related to river orders and positively related to N loading. The ability of river ecosystems to convert excess DIN into N2O decreases with increasing N load. The N2O emissions in the whole Changjiang River network has significantly increased from 1986 to 2014. Headwater streams are hotspots for N2O emission. An integrated approach considering river N loads and hydrology is needed to improve estimates of riverine N2O emissions.

Summary: This study explored the behaviour and mobilization mechanism of dissolved phosphorus (P) in a shallow sandy aquifer and a deep sand-gravel aquifer. The results showed that the enrichment of dissolved P in both aquifers was mainly related to organic matter degradation and reduction of Fe(III) oxides. The shallow aquifer had significantly higher total dissolved phosphorus concentrations compared to the deep aquifer, due to the stronger reductive dissolution of Fe(III) oxides with higher P/Fe molar ratio. The study highlights that geogenic enrichment of P in groundwater can occur in sand-gravel aquifers with high P and Fe(III) oxide contents under reducing conditions, and that the P/Fe molar ratio in Fe(III) oxides is the most important controlling factor for dissolved P in groundwater systems.

Summary: To better understand the dynamics of N2O in the atmosphere, we reconstructed N2O values from ice cores, firn air archives, and modern atmospheric samples. Our findings show a three-phased growth of N2O, with a significant increase after 1965 CE. The decreasing trend in isotope values suggests an increasing contribution from anthropogenic sources. The continental region has been identified as the major hotspot of anthropogenic emissions.

Summary: Plastics in aquatic ecosystems easily attract diverse microbes, forming unique microbial communities known as the "plastisphere" that differ from surrounding water and other substrates. High-throughput sequencing revealed that the diversity and structure of bacterial communities varied on different types of plastics, while fungal communities showed no significant differences. Co-occurrence network analysis demonstrated that interactions between bacteria and fungi were less complex on microplastics compared to plastic sheets.

Summary: This study investigated the impact of effluent discharge on bacterial communities and water-soluble organic matter (WSOM) in benthic biofilms. The results showed significant changes in bacterial communities and WSOM characteristics in the discharge area, while the changes were smaller in biofilms collected upstream and downstream from the wastewater treatment plant. Although effluent discharge simplified the network pattern of the biofilm bacterial community, its metabolic functional abundance remained stable. The study highlights the important ecological role of carbon metabolism in effluent-receiving rivers.

Summary: This study found that iron-loaded biochars (FeBCs) can accelerate the simultaneous removal of nitrate and bisphenol A (BPA) from aquatic systems. FeBCs have high electron transfer efficiency and redox activity, which can enhance microbial metabolism and degradation ability. The addition of FeBCs increased the activity of denitrifying enzymes and the level of nitrate-reducing genes, as well as the abundance of bacterial genera responsible for BPA degradation. Moreover, the ferric-containing functional groups were significantly correlated with nitrate-reducing enzymes and metabolic activities, facilitating the simultaneous removal of nitrate and BPA.

Summary: Controlled surface water systems, such as those with dams, can cause dynamic changes in water levels, resulting in altered flow exchange patterns in the hyporheic zones. However, the effects on nitrogen transformation, dissolved organic matter (DOM) composition, and microbial communities under different scenarios of water source and hyporheic exchange have been poorly studied. This research investigated the nitrogen transformation in hyporheic zone sediments and focused on the relationship between microbial community structure, biological functions related to nitrogen transformation, and sediment-attached DOM compositions. The study found that the mixing of river water and groundwater enhanced microbial diversity, complexity of microbial co-occurrence networks, and nitrogen transformation functions. The composition of sediment-attached DOM was primarily humic fractions after hyporheic exchanges. Species such as Nitrospinae, Dinghuibacter, and Lentimicrobium played key roles in metabolizing nitrogen and DOM in the hyporheic sediments. This study provides valuable insights into the effects of water chemistry changes on nitrogen transformation, DOM compositional changes, and the linkages between community structure and DOM fractions in the hyporheic zones.
