Summary: The study shows that future urban expansion may slightly reduce heat stress during the day, but significantly intensify it at night, especially in mega-urban regions. Installing cool roofs can partially offset the heat stress caused by climate change induced by greenhouse gases, however, it does not fully mitigate the nighttime risks.

Summary: This study reviewed the literature on scenario experiments that focused on the impact of urbanization on urban heat islands. Based on existing research, urbanization is divided into five features: land use and land cover, urban morphology, canopy surface, anthropogenic heat release, and response to global warming. The study evaluated the type of urban canopy model, land use data, and input methods used in the experiments for these five scenarios, analyzed UHI-related indicators, and assessed the real-world scenarios and variables involved in each urbanization feature. The aim of this study was to assist researchers in selecting appropriate modeling methods and UHI-related indicators based on the urbanization features of their focus.

Summary: Urbanization leads to significant land use/land cover changes and increases urban heat island effect. This study analyzes the spatial distribution patterns of land use/land cover changes and surface urban heat island intensity, as well as the relationship between impervious surface and vegetation coverage and urban heat island intensity. The future land cover and land surface temperature in Shanghai are predicted under different development scenarios. The results show that the ecological space protection model can effectively reduce the urban heat island effect.

Summary: Urban flooding is a common problem in cities due to rapid urbanization and climate change. This study aims to identify trends and gaps in urban flooding research in South Asia. Based on a literature review, it reviewed urban flood hazard assessment methods and management practices in the region. Hydraulic/hydrological models such as HEC-RAS/HMS, MIKE, and SWMM are used for flood hazard assessment, and both conventional and innovative techniques are implemented for flood management. However, challenges such as the lack of high-resolution data affect model accuracy and the implementation of effective flood management measures.

Summary: Urbanization is a major global problem that affects the atmosphere and land surface properties. The intensity of Urban Heat Island (UHI) was assessed using the Community Land Model (CLM), showing a consistent increasing trend with urban expansion and its correlation with Land Use/Land Cover (LULC) and climate variations in Melbourne. During extreme climate events, UHI was influenced by factors such as convection reduction, surface evaporative cooling, and heat storage release.

Summary: The urban heat island effect poses a threat to human survival, but evaporation from water bodies can effectively cool temperatures and alleviate this effect. This study proposes a customized urban water body evaporation model that considers anthropogenic heat flux and improves simulation performance. Results show that the model outperforms traditional models in simulating evaporation and that urbanization increases the contribution of evaporation cooling to alleviating the urban heat island effect.

Summary: Rapid urbanization and human demands impact carbon emissions and contribute to global warming. This study assessed carbon emissions dynamics in Penang City, Malaysia and their impact on land surface temperature (LST) change and urban heat island (UHI) effects. The findings reveal a decrease in forest cover, an increase in urban areas, and significant increases in average LST and UHI. The decrease in carbon stock concentration is attributed to the loss of vegetative cover. Strong positive correlations between carbon emissions and LST and UHI suggest that carbon emissions are highly responsible for temperature increase and UHI effects. Effective strategies such as afforestation and urban greening are proposed to improve carbon storage capacity and reduce climate change impacts.

Summary: This research uses three dynamically downscaled regional climate models (RCM1 - RCM3) and two representative concentration pathways (RCP4.5 and 8.5) to project future climate change-induced urban heat island (UHI) trends (2022-2099). The findings reveal that the Bangkok metropolitan area is highly likely to experience warmer temperatures in the future, contributing to higher land surface temperature and UHI intensity.

Summary: The urban heat island effect has adverse impacts on human health and the environment as well. The use of vegetation, particularly urban tree planting, is considered as a potential strategy to mitigate the heat island effect. By using the i-Tree Cool Air model, the variations and spatial distribution of air temperature in the city of Padova, Italy were analyzed, showing lower air temperatures in areas with tree canopy. However, further research is necessary to determine the reliability of temperature predictions.

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: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

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.
