Summary: Rapid urbanization leads to increased surface runoff, and the classification of landscape (land use/land cover) in the model is a methodological issue in studying land use effects. This study used the L-THIA model to simulate the change in annual surface runoff during the rapid urbanization in Shanghai since 1965. Two landscape scenarios based on land uses and pervious/impervious surfaces were compared, showing almost no difference in the results. It was suggested that the simplified scenario based on pervious/impervious surfaces is workable and efficient, and the land use scenario may not be necessary. The study also found a clear linear relationship between the percentage of impervious surfaces and surface runoff.

Summary: Land use change has a significant impact on the runoff characteristics of the basin, with different land use types showing varying hydrological responses. However, the impact on annual runoff is minimal. Returning farmland to woodlands and grasslands promotes groundwater recharge and plays a positive role in ecological restoration in the basin. These findings are of great importance for understanding the hydrological consequences of land use change and for the rational planning of land use patterns in river basins.

Summary: The research investigates the hydrological impacts of historical and future land use land cover (LULC) in a specific part of the Yamuna River basin. The study evaluates the effectiveness of the GIS-Curve Number (CN) approach in calculating effective impervious area (EIA) for larger ungauged basins. The Soil and Water Assessment Tool (SWAT) is used to simulate hydrological responses in different land-use scenarios. The findings indicate a decline in groundwater resources and an increase in surface runoff due to urbanization.

Summary: This study explores the impact of impervious surface density on the thermal environment by analyzing the spatial patterns of impervious surfaces in the Xuzhou built-up area. The results suggest that increasing the types, even distribution degree, and density of impervious surfaces, or decreasing the aggregation degree, can enhance the thermal environment. Additionally, the proportion, shape complexity, aggregation degree, and natural connectivity of impervious surfaces at different levels of density are important factors affecting the urban heat island effect. The landscape patterns of impervious surfaces at density levels 4 and 5 have a significant impact on the thermal environment.

Summary: Groundwater extraction has significant impacts on hydrological processes, altering soil moisture content and latent heat flux. In the Beijing-Tianjin-Hebei region from 2000 to 2012, groundwater extraction deepened the groundwater table, increased soil moisture, and reduced terrestrial water storage.

Summary: The north of Iran is experiencing frequent floods and significant economic and natural losses, despite being the greenest region in the country. A study was conducted in the Gharesou Watershed of Golestan Province, Iran to understand the hydrological response to changes in land cover and land use. Using landscape metrics, changes in land cover and fragmentation were analyzed for the years 1984, 1994, 2014, and 2030. The study found that the annual average runoff in the watershed increased from 6.15 to 6.78 m(3)/0.09 ha/yr from 1984 to 2014, and is predicted to continue increasing to above 6.98 m(3)/0.09 ha/yr by 2030. It was also found that certain land cover types, such as industrial and high-density residential areas, contribute more to runoff generation compared to forest and grassland areas.

Summary: This study evaluated the changes in hydrological and sediment connectivity in the Santa Cruz catchment in Mexico over a period of 42 years and projected these changes under a climate change scenario. The results showed that changes in land use/cover and expected climate change would modify hydrological and sediment connectivity. Under future conditions, there is likely to be an increase in runoff and sediment transport, which will impact soil erosion and vulnerability to flooding.

Summary: This study provides a 30-m impervious surface area dataset for the Arctic from 1985 to 2021 and utilizes adaptive random forest classifiers for long time-series impervious surface mapping. The results show that the impervious surface area in the Arctic has been increasing over the past 37 years, with the majority of the increment located in Russia, Finland, and Norway. The study also analyzes the sources of impervious surface expansion in the Arctic, revealing that tundra, forest, and grassland are the top three land covers transformed into impervious surfaces.

Summary: Recent advances in global hydrological modeling have generated multiple global runoff datasets used extensively in global hydrological analyses. This study evaluates the simulated runoff from 21 global models against observed streamflow in 840 catchments globally and finds that model performance varies across regions and aspects of runoff estimation. The study highlights the need for caution in interpreting assessments/projections of runoff changes based on these models due to uncertainties and calls for advanced observation-guided ensemble techniques for better large-scale hydrological applications.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
