Summary: This study investigated the assembly processes of microbial communities in heavily polluted urban river and found that the assembly mechanisms of rare and abundant subcommunities were different. Interspecific interactions played a more important role in the assembly of rare subcommunities, while both interspecific interactions and environmental selection affected the assembly of abundant subcommunities. The results provided valuable insights into the assembly mechanisms of microbial communities in heavily polluted running water ecosystems.

Summary: The study found that there is a non-linear dose-response relationship between temperature, PM2.5, and the risk of hand-foot-mouth disease. Both low temperature and high temperature can increase the risk of hand-foot-mouth disease. The concentration of PM2.5 between 76 to 200 μg/m³ poses a certain risk for the onset of hand, foot, and mouth disease.

Summary: Anthropogenic pollution has significant impact on river water quality, especially in urban areas of Africa. This study evaluated the impact of urbanization on the water quality of four urban rivers in Tanzania through water quality index and statistical analysis. The results showed that the water quality was significantly deteriorated in the lower reaches of the cities, indicating pollution characteristics in urban rivers of Africa. Some river sections had medium to good water quality, but the decline was mainly observed in the urban central areas, indicating a growing pollution tendency with the increasing population. Therefore, timely monitoring of surface water quality with an economical and feasible method is necessary to formulate water pollution control policies in response to rapid urban expansion in African countries.

Summary: The Thriassion Plain, the Saronikos Gulf and Eleusis Bay in Western Attica, Greece, are facing pressures from extensive industrial activity and urban development. These areas are considered as brownfields due to the contamination of soil, groundwater, coastal sediments, and the nearby Koumoundourou Lake. High concentrations of metals and oil products have been found in these regions. This study analyzes published papers to provide a pollution record of legislated compounds, aiming to support researchers in finding solutions and policy makers in developing effective policies.

Summary: This study investigates the urbanization effect on water resources in a developing semi-urban area near Chattogram city. The findings show that household water demand is influenced by family size and income. While pH, TDS, and Cl- values in water samples are generally acceptable, EC, SS, and COD values exceed water quality standards, making the water less suitable for domestic use. The main causes of water quality degradation are waste disposal, saltwater intrusion, and industrial discharge.

Summary: Microbial activities in highly polluted waters are promoted, and a unique microbiome was discovered in East Lake with Proteobacteria being the dominant taxonomic group. Functional analysis revealed abundant predicted functional genes for sulfur compound respiration and sulfate respiration. This work provides evidence for future microbiome studies in nutrient-rich, alkalic, and seasonally frozen water habitats.

Summary: With the advancement of urbanization, the structure and connectivity of river networks have been changed by human activities, leading to water environment problems. We studied a water conservancy region in the Taihu Plain and found that water quality is better during the flood season, especially in the western region. The spatial aggregations of water quality indicators are higher and polluted regions increase in size during the flood period compared to the non-flood period. The relative contribution rates of river density and connectivity to water quality are 62.5% and 37.5% in the flood and non-flood periods, respectively.

Summary: This study used panel data from 2011 to 2020 to examine the effects of urbanization on air pollution and ecological resilience in the Yellow River Basin. The results show that there is a U-shaped relationship between urbanization and air pollution, as well as an inverted U-shaped relationship between urbanization and ecological resilience. Additionally, urbanization has a spatial spillover effect and negatively impacts the ecological environment of neighboring cities.

Summary: This study utilized immobilized native photosynthetic bacteria (PSB) to treat heavily polluted river water, demonstrating a significant reduction in chemical oxygen demand (COD) within 120 hours, as well as high removal efficiency of sulfide and ammonia nitrogen. The turbidity of the heavily polluted river water was greatly reduced after treatment with immobilized PSB, suggesting a promising approach for enhancing performance in water bodies with specific conditions.

Summary: The study investigates the urbanization and water quality dynamics in coastal margins of mainland China, revealing that urbanization has increased significantly while water quality remained relatively stable. The findings highlight the importance of managing urbanization and preserving coastal water quality in these regions. The research provides valuable scientific information for decision-making and enhances the understanding of the urbanization process and its environmental impact.

Summary: The study found that acid mine drainage can lead to significant changes in the community composition and amino acid profiles of macroinvertebrates, resulting in significantly lower taxa richness at polluted sites. There were significant variations in the AA profiles among different taxa and different river sections, reflecting the response of macroinvertebrates to AMD contamination.

Summary: In this study, the effects of different biochar doses on soil cadmium contamination and the yield and quality of Erigeron breviscapus were investigated. The results showed that biochar application changed the soil cadmium speciation and reduced the concentrations of cadmium in both plants and soil. Furthermore, it increased the biomass and specific compound content of Erigeron breviscapus. This study provides important reference for the simultaneous utilization and remediation of heavily cadmium-contaminated soil.

Summary: The rapid development of new urbanization has put great pressure on the ecological environment. Understanding the interaction mechanism between ecological environment and new urbanization is crucial for sustainable development. This study focused on the Nanchang metropolitan area in China and used comprehensive assessment models to analyze the spatial and temporal heterogeneity, spatial correlation, and interaction strength between ecological quality and new urbanization level. The results showed improvements in ecological quality and urbanization level from 2005 to 2018. The study also identified synergistic and trade-off relationships between land use efficiency and ecological quality, as well as synergistic relationships between economic development and ecological quality. The findings provide insights for urbanization construction and the coordinated development of natural resources and urban construction.
