Summary: Reclaimed water irrigation showed no significant impact on phenol concentrations in agricultural topsoil and products, as well as bioaccumulation factors (BCFs) and yields of wheat and vegetables compared to groundwater irrigation. However, further experiments are needed to analyze the effects of reclaimed water quality on the risk of phenol contamination.

Summary: This paper provides a systematic review of the sources, hazards, and impacts of microplastics in the Changjiang Estuary. It analyzes the current research on microplastics in the estuary and presents the abundance, characteristics, and primary sources of microplastics in the area. The paper also offers relevant suggestions based on the specific situation of the Changjiang River Estuary and developed microplastic treatment technologies. It serves as a structured reference for future research and helps in assessing the ecological impact of microplastics.

Summary: This study investigated the occurrence of microplastics in surface water along an urban river in Guangzhou, China during wet and dry seasons. The abundances of microplastics showed an increasing trend from upstream to midstream and a decreasing trend from midstream to downstream and estuaries. The study also found that the abundance of microplastics was higher in the dry season in the central urban area. The results provide valuable information for source apportionment and development of measures to control microplastics pollution.

Summary: This study investigated the concentrations of nonylphenols, octylphenol, and nonylphenol ethoxylates in the Canadian freshwater environment. The compounds were detected more frequently in urban and municipal wastewater treatment plant-associated sites. There was a statistically significant downward trend in NP concentrations in Canadian surface waters from 2014 to 2019, and no exceedances of the Canadian Water Quality Guideline were observed.

Summary: This study reveals that BPA, OP, and NP exhibit acute toxicity to earthworms and cyto-/geno-toxicity to monocotyledonous plants at low concentrations. However, the interaction among these phenols reduces the magnitude of their individual effects on plants in the mixture.

Summary: This study provides the first record of microplastic contamination in various matrices along a river ecosystem. Microplastics were found in both abiotic and biotic samples, suggesting an efficient uptake pathway into organisms. However, microplastic levels were not correlated among different matrices and did not increase with the length of the river. The calculated microplastic load transported by the river was lower than the estimated load from wastewater treatment plants. These findings indicate that the hydrological network of the river retains a consistent amount of microplastics over time.

Summary: The objective of this study was to assess micropollutant removal during ozone disinfection of wastewater, utilizing targeted and untargeted screening analyses. Effluents from two wastewater treatment plants were treated with ozone at various doses and analyzed using gas chromatography coupled with Orbitrap High-Resolution Mass Spectrometry. The removal of different chemical families was evaluated in relation to the level of Escherichia coli and the total removal of coliforms. The proposed methodology aims to provide a new protocol for the careful evaluation of ozonized wastewater effluents for disposal and reuse.

Summary: The study found that exposure to 2-t-OP is associated with a higher risk of GDM, while higher NP exposure is associated with a lower GDM risk. Further research is needed to confirm these associations and elucidate the causality of the findings.

Summary: This study evaluated the phosphorus transfer process and influence factors at the Sediment-Water Interface (SWI) in the Huaihe River. The findings highlighted the role of riverbed sediment as a pollution sink, the significant impact of land use on phosphorus, and the applicability of the proposed model in other polluted rivers.

Summary: This study systematically investigated the fate, trends, and potential sources of 57 PFASs in the North and West Rivers of the Pearl River system. It found that PFOA, PFOS, and 6:2Cl-PFESA were frequently present in waters, sediments, and fish, with higher PFAS loads contributed by the North River to the Pearl River Delta. Additionally, there is a shift in PFAS usage from legacy substances to alternatives in this area.

Summary: This study conducted a statistical analysis of the occurrence and ecological relevance of nonylphenol, octylphenol, and their ethoxylates in fresh and marine surface waters and sediments in the United States from 2010 to 2020. The results showed a decrease in concentrations of nonylphenol and octylphenol in fresh surface waters and sediments, while concentrations in marine waters and sediments were more variable. The environmental risk assessment indicated a low potential for risk to aquatic organisms, as less than 1% of samples exceeded environmental quality guidelines and no exceedances were noted after 2016.

Summary: The distribution, migration, and enrichment of arsenic in groundwater is an important environmental and public health problem. This study assesses the potential pollution risk of arsenic-rich groundwater, analyzes the hydrogeochemical processes, and traces the ion source based on groundwater hydrogeochemical data. The findings suggest that arsenic poses a high exposure risk for public health in the study area, with 23% of samples exceeding the drinking water standards of the World Health Organization.

Summary: This study analyzed the temporal and spatial variations in surface water quality in the Huaihe River Basin from 2011 to 2018 and identified the main factors influencing these variations. The results showed that the water quality in the basin has been improving, with rainfall changes playing an important role. The urbanization rate, industrial water consumption, and rainfall were identified as key factors influencing water quality changes. In the future, the sewage treatment rate and rainfall changes caused by natural variations will be important factors affecting water quality changes.
