Using different configurations of -planted constructed wetland-microbial fuel cells to remove Cr (Ⅵ) and p-chlorophenol and generate electricity.

P-chlorophenol (4-CP) and hexavalent chromium (Cr (VI)) are predominant contaminants in industrial effluents, eliciting substantial environmental and human health concerns. As a strong oxidant, Cr (Ⅵ) has the potential to facilitate the removal of 4-CP. However, the specific removal effect remains unclear.

Characterizing the precursors of byproducts formed by chlorine and chlorine dioxide disinfection using unknown screening analysis with Orbitrap mass spectrometry.

Chlorine (Cl) and chlorine dioxide (ClO) are commonly used to disinfect water but unfavorable interactions with dissolved organic matter (DOM) result in the formation of disinfection byproducts (DBPs). This study investigated the formation of organic DBPs arising from Cl and ClO disinfections under different contact times in two surface waters in Thailand and Suwannee River natural organic matter with/without bromide using unknown screening analysis with Orbitrap mass spectrometry. Many CHOCl-DBPs and CHOBr-DBPs intermediates were rapidly formed during the initial period of contact (5-30 min).

[Spatial-temporal Variations and Driving Factors Analysis of Total Nitrogen Concentration in the Haihe River Basin from 2018 to 2022].

The Beijing-Tianjin-Hebei （Jing-Jin-Ji） Region is home to the most acute economic, resource, and environmental conflicts in the Bohai Sea region, and the rivers entering the sea carry abundant total nitrogen （TN） input into the Bohai Bay, which is the main land-based input causing eutrophication of the bay. The Haihe River Basin in the Jing-Jin-Ji Region was divided into 112 （2018-2019） and 187 （2020-2022） control units, and the spatial and temporal variations in TN concentration in the surface water of the Haihe River Basin in the Jing-Jin-Ji Region were systematically analyzed from 2018 to 2022 by combining the Euclidean distance analysis method and the K-means clustering analysis method. The results showed that the annual average concentration of TN in the region showed a trend of decreasing （2018-2020） and then increasing （2021-2022）, in which the concentration of TN increased significantly from June 2021 to June 2022.

Evidence of sewage discharge on the coalescence mechanism of aquatic microbial communities during high amplitude hydrological periods.

Microbial community coalescence is a ubiquitous ecological process in various ecosystems. However, limited research has addressed the effects of the coalescence on microbial ecological processes and network structure, particularly in the context of sewage discharge during high amplitude hydrological periods. Employing 16S rRNA sequencing and species source tracking analysis, we investigated the coalescence pattern of bacterioplankton in the Chishui river and sewage across various hydrological periods.

Impacts of long-term irrigation of municipally-treated wastewater to the soil microbial and nutrient properties.

Reusing treated wastewater (TWW) for crop irrigation has shown to provide environmental and economic benefits as well as drawbacks. This study was conducted using soils collected from a wastewater reuse facility in Tallahassee, FL, mainly to elucidate the long-term impact(s) of TWW irrigation on soil microbiome and nutrient status. Approximately 890 ha of land have been spray-irrigated with TWW since the 1980's to grow fodder crops.

Wastewater-based estimation of temporal variation in shedding amount of influenza A virus and clinically identified cases using the PRESENS model.

Wastewater-based estimation of infectious disease prevalence in real-time assists public health authorities in developing effective responses to current outbreaks. However, wastewater-based estimation for IAV remains poorly demonstrated, partially because of a lack of knowledge about temporal variation in shedding amount of an IAV-infected person. In this study, we applied two mathematical models to previously collected wastewater and clinical data from four U.

Microbial electrochemical technologies (MET) can remove a variety of organic and inorganic pollutants from contaminated groundwater. However, despite significant laboratory-scale successes over the past decade, field-scale applications remain limited.

Enhanced photocatalytic performance and a mechanistic study of novel black phosphorus/graphene/TiO composite membrane for o-chlorophenol removal.

The heterogeneous catalysis of the composite membrane not only exerts the synergistic effect of different materials but also enable the recyclable use of catalysts, making it an ideal and sustainable strategy for removing pollutants in water. In this study, a novel black phosphorus/graphene/titanium dioxide (BP/GR/TiO) membrane was successfully prepared through the sol-gel method. The composite membrane not only overcame the instability of black phosphorus and the rapid recombination of e/h pairs in titanium dioxide but also synergized with GR to produce a new reactive oxygen species (ROS), singlet oxygen (O), with a longer lifetime and migration distance.

The La-NCF/SA-PEI hydrogel, featuring a 3D porous structure with interwoven functional groups (amino, quaternary ammonium, and lanthanum), demonstrated a maximum P adsorption capacity of 78.

Enhancing rainwater harvesting efficiency in karst terrains: The role of road intercepted soil-epikarst lateral flow.

In karst landscapes, where sustainable water management is increasingly challenged by drought-induced water scarcity, the adoption of road-based rainwater harvesting (RBWH) systems has emerged as a promising solution for improving water accessibility. Despite the growing implementation of such systems, the effectiveness of many RBWH projects in karst terrains remains suboptimal due to an inadequate understanding of runoff generation mechanisms associated with hilly road networks. This study focuses on quantifying the contributions of intercepted surface runoff (SR) and soil-epikarst lateral flow (SEF) from a newly exposed road-cut slope in a dolomite hillslope, with data collected across 156 rainfall events from May 2019 to May 2022.

Haloacetamides exacerbate non-alcoholic fatty liver disease induced by a high-fat diet in C57BL/6J mice.

Obesity, a significant global health issue, heightens the risk of non-alcoholic fatty liver disease (NAFLD). Its interaction with environmental pollutants might exacerbate NAFLD's severity. Haloacetamides (HAcAms), a group of emerging nitrogenous disinfection by-products (DBPs) and potent oxidative stressors, are found in chlorinated drinking water.

Removal and ecological impact of sulfamethoxazole and N-acetyl sulfamethoxazole in mesocosmic wetlands dominated by submerged plants: Plant tolerance, microbial response, and nitrogen transformation.

Sulfamethoxazole (SMX) and its human metabolite N-acetylsulfamethoxazole (N-SMX) are frequently detected in aquatic environments, posing potential threats to freshwater ecosystem health. Constructed wetlands are pivotal for wastewater treatment, with plant species serving as key determinants of pollutant removal efficiency. In this study, wetlands dominated by three submerged plants (Myriophyllum verticillatum, Vallisneria spiralis, Hydrilla verticillata) were respectively constructed to investigate the removal of SMX and N-SMX, and the impact on wetland ecology regarding plant tolerance, microbial response, and nitrogen transformation.

Functional characteristics and mechanisms of microbial community succession and assembly in a long-term moving bed biofilm reactor treating real municipal wastewater.
