Summary: The study examines the effects of lockdown measures on PM2.5 concentrations during the COVID-19 pandemic, finding significant reductions in China and slight changes in Europe and North America. These changes are attributed to a combination of meteorological conditions and emission reductions, primarily from transportation sources. Regional differences in the sensitivity of PM2.5 to emission sources are demonstrated in this work.

Summary: The COVID-19 pandemic has caused significant health emergencies and pollution crises, particularly in developing countries with inadequate waste management. Improper waste segregation has led to contamination of water, air, and agricultural fields, facilitating the growth and transmission of disease-causing agents. Short- and long-term solutions are needed to mitigate the adverse effects and address the excessive use of plastics and their products.

Summary: Natural clay mineral and its modifier, modified clay, have been used in environmental applications for years, but they are not capable enough to achieve higher conversion rate and ecological sustainability due to a lack of understanding of their selectivity or compatibility with pollutants. The development and implementation of green principles have become an emerging field that combines green chemistry and engineering practices to achieve a pollutant-free environment. This review summarizes the role of clay/modified clay in pollution control and discusses the role of green chemistry in global sustainability.

Summary: DEHP is a plasticizer widely used in the plastic industry to provide softness to PVC. Despite regulations, it remains a widespread contaminant in EU watersheds. The study shows that limiting its use will not significantly reduce future emissions due to high existing stocks and long-term presence of PVC waste in landfills. This highlights the importance of avoiding the use of hazardous chemicals with persistent characteristics in products.

Summary: Air pollution in China is mainly caused by substantial anthropogenic emissions and significant secondary formation processes. During the COVID-19 lockdown, a reduction in anthropogenic emissions led to lower concentrations of six ambient pollutants, with BTH suffering from more serious air pollution compared to YRD. The increase in PM2.5 and differences in CO and NO2 ratios during the lockdown period indicate the dominant contribution of secondary processes on PM2.5, emphasizing the importance of reducing anthropogenic emissions to mitigate PM2.5 pollution.

Summary: We conducted in situ measurements of black carbon (BC) concentration in Chennai, India from January to June 2020. The results showed an unprecedented reduction in BC concentration during the COVID-19 lockdown, despite stronger precipitation. The study also revealed that BC depletion was more pronounced in continental air than in marine air, and there was a shift from fossil-fuel dominance to biomass burning dominance as a BC source.

Summary: The increasing global industrialization and over-exploitation of fossil fuels have resulted in higher greenhouse gas emissions, leading to rising global temperatures and environmental issues. Achieving net-zero carbon emissions requires a comprehensive approach involving renewable energy transition, development of negative emissions technologies, implementation of carbon trading and carbon tax, as well as changes in dietary habits, low-carbon agriculture, and improving waste management. It is also crucial to build resilient buildings and cities, adopt decentralized energy systems, and electrify the transportation sector.

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.

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.
