Summary: Sub-Saharan Africa is experiencing rapid urbanization, with air pollution emerging as a major concern in growing cities, especially in Accra, Ghana. The study found that commercial, business, and industrial areas have the highest levels of PM2.5 pollution, with concentrations 2-4 times higher than WHO guidelines. Additionally, PM2.5 levels peak during the dry dusty Harmattan period, and have decreased by 50% compared to measurements in 2006-2007. Effective policies are needed to reduce pollution levels and protect public health in urban areas.

Summary: This study developed high resolution spatiotemporal land use regression models to map fine particulate matter and black carbon concentrations in the Greater Accra Metropolitan Area in West Africa. The results showed that the population in this area is exposed to PM2.5 levels above the World Health Organization guideline, with higher exposures in poorer neighborhoods. These models can be used to support air pollution mitigation policies and health and climate impact assessments, and can be adapted to other African cities to fill the air pollution data gap in the region.

Summary: This study provides the first quantitative assessment of spatial and seasonal variations of outdoor black carbon and PM2.5 concentrations in several densely populated slums of Mumbai, India. The results indicate that slum residents in Mumbai and similar slums are at a higher risk of traffic-related air pollution, especially during winter. Targeted mitigation strategies to reduce vehicular emissions, especially in high-traffic slums, are recommended.

Summary: This study investigates the acute effects of personal exposure to PM2.5 on self-reported asthma-related health. The results show individual exposure to PM2.5 varies across microenvironments and is associated with asthma symptoms. However, there is no significant association between exposure and reliever inhaler use.

Summary: There is limited research on the relationship between low levels of daily fine particulate matter (PM2.5) exposure and morbidity or mortality in non-western countries, especially at PM2.5 concentrations below 15 μg/m3, the latest WHO AQG value. This study in Japan found that even at low concentrations, an increase in PM2.5 was associated with an increase in cardiorespiratory hospital admissions. The findings suggest that the current WHO guideline value may be insufficient for protecting public health.

Summary: The study conducted in downtown Lanzhou, Northwest China, found that vehicle emissions were the major source of PM pollution, especially in winter and autumn when they made significant contributions. With the reduction in industrial emissions and increase in vehicle numbers in China in recent years, vehicle emissions are projected to become the largest source of urban PM pollution. Efforts to control vehicle emissions, such as promoting clean-energy vehicles and encouraging public transportation, are crucial for sustainable improvement of air quality in Lanzhou and other Chinese cities.

Summary: The study found a positive association between specific elemental components of PM2.5 and lung cancer incidence, with combustion particles from oil and biomass burning and secondary inorganic aerosols showing higher risk. Specific limit values or guidelines targeting these specific PM2.5 components may prove helpful in future lung cancer prevention strategies.

Summary: Air pollution is a global risk factor for impaired lung health and increased morbidity and mortality. The MicroPEM and ECM are wearable monitors for personal exposure to fine particulate matter, which have reasonable rates of acceptability in mothers and children. However, high PM2.5 exposure in children is a concern and strategies to minimize exposure need to be strengthened.

Summary: This study examined the short-term effects of exposure to PM2.5 on cardiovascular diseases hospitalizations in Lanzhou, China. The results showed a positive correlation between PM2.5 and daily admissions for total or cause-specific CVD, with both low and high temperatures increasing the risk. Stratified analysis by gender and age did not reveal any differences. The study also found an almost linear relationship between PM2.5 exposure and cause-specific CVD admissions, with males and the elderly being more vulnerable.

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: Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Little is known about microbial community resistance and adaptation to disturbances, hindering our understanding of recovery latency and implications for ecosystem functioning. This study found that anthropic disturbance and natural disturbance have different effects on the topology and stability of soil microbial networks.

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.
