Summary: Tire wear particles are identified as a major source of microplastic pollution. Field measurements were conducted to characterize and quantify these particles in different matrices. The results revealed the presence of traffic-derived microplastics in road dust, runoff, and air, with the finer fraction dominating in all sample matrices. These particles have the potential to be transported in water and air, contributing to inhalable particle fraction in the air.

Summary: This study focused on real-time high-frequency UFPs particle size distribution in an indoor site, revealing that accumulation mode (AM) of UFPs during working days contributes significantly to the total particle number concentration, showing a high correlation with polycyclic aromatic hydrocarbons (PAHs) contribution. Additionally, high indoor TPNC values were recorded during rush hours, potentially due to outdoor influences from anthropogenic activities.

Summary: The study revealed that indoor air pollution from particles, mainly caused by indoor activities like cooking, leads to prolonged indoor particle concentrations. Outdoor sources were found to be the predominant sources of particle exposure, suggesting that reducing outdoor penetration is crucial in lowering indoor PN concentration by improving building airtightness through the addition of air filtration.

Summary: This study determined the sources of indoor particulate matter at Potala Palace Museum in Tibet, China and evaluated the potential hazards of these pollutants for cultural relics. The research found that the indoor PM1-10 concentration was much higher than the outdoor concentration, and was less affected by outdoor sources. Proper ventilation and the installation of air conditioning systems can help dilute indoor suspended particulate matter and better protect the museum's cultural relics.

Summary: The study examined dust pollution levels at four locations in the Tema metropolitan area over a nine-month period, finding no significant difference in pollution levels across locations. Out of 36 weeks of monitoring, significantly high concentrations of PM2.5, PM10, and TSP were recorded for 8, 11, and 5 weeks respectively, with the oil jetty area and the VALCO hospital area showing significantly high concentrations of dust pollution. The study recommends urgent air quality control policy intervention to address the alarming levels of dust pollution concentrations.

Summary: This study aimed to bridge the gap between lack of awareness and understanding of how occupant behavior affects indoor air quality (IAQ). An evaluation of IAQ awareness and an investigation of an eco-feedback strategy were conducted. The results showed that occupants were not properly aware of IAQ in their homes, but the eco-feedback strategy successfully promoted behavioral changes and reduced particle concentration during cooking activities.

Summary: A drastic household clean heating renovation has been undertaken in rural northern China since 2017, which aims to improve indoor air quality. The study incorporates the deposition efficiency of particulate matters (PMs) in the human respiratory tract to assess the health risks of homemakers inhaling polycyclic aromatic hydrocarbons (PAHs) emitted from different solid fuels. The results demonstrate that using clean coal significantly reduces the exposure levels of PAHs, and replacing biomass and raw coal chunk with clean coal greatly decreases the cancer risks.

Summary: The central government of China implemented a clean heating policy in northern China in 2017 to reduce the adverse effects of traditional domestic solid fuel. Clean coal is currently used as a low-cost alternative fuel for rural households. This study evaluated the benefits of clean heating transformation in Tongchuan, China by selecting 18 households that used different types of fuel. The results showed that clean coal significantly reduced indoor and personal exposure to fine particulate matter (PM2.5) compared to lump coal and biomass. Transition metals were found to be the principal components responsible for oxidative stress.

Summary: In this study, a novel heterostructured SrTiO3/SrCO3 (STO/SCO) interface was constructed via a one-pot g-C3N4 (CN) self-sacrificing hydrothermal strategy. The as-developed STO/SCO photocatalyst showed high degradation rates for NO and HCHO in continuous-flow reactors. The presence of CN in the crystallization process as the source of CO32- enabled the formation of the STO/SCO interface. Additionally, enhanced chemisorption effects of O-2 on the catalyst surface were observed, leading to photocatalytic oxidation under simulated solar light.

Summary: Air pollution caused by particulate matter and ozone in Chinese megacities is a major health concern, partially due to the emissions of nitrogen oxides. Therefore, advanced methods, such as photocalysis using polymeric carbon nitride, are needed for nitrogen oxide removal. However, this process is limited by low visible-light absorption, specific surface area, carrier recombination, and conversion pathways. In this review, catalysts made of polymeric carbon nitride for the removal of nitrogen oxides are discussed, focusing on improving light absorption, increasing surface area, inhibiting carrier recombination, regulating the reaction process, outdoor applications, and reducing nitrogen oxides to dinitrogen.

Summary: This study compared the emissions and cytotoxicity of PM2.5 from three types of biomass fuel and their processed fuels. It was found that the PM2.5 emission factors of maize and wheat straw were higher than those of wood branches, but were effectively reduced after briquetting and carbonization. Cell membrane damage and inflammatory responses were observed after exposure to PM2.5, but the bioreactivity was lower for processed fuels. The study identified key chemical components that contributed to oxidative and inflammatory responses, and emphasized the importance of fuel treatment in reducing cytotoxicity.

Summary: Volatile organic compounds (VOCs) emitted from solid fuel combustion play a dominant role in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOAs). This study collected freshly emitted and aged VOCs from various common solid fuel combustions and analyzed their composition and degradation. The results showed that aromatic and oxygenated VOCs were the most abundant groups, and briquette technology effectively reduced VOC emissions. Different VOCs exhibited significant degradation after aging, with alkenes in biomass and aromatics in coal showing the largest degradation. Long-timescale observation of VOC species is essential for understanding regional transport effects.

Summary: Volatile organic compounds (VOCs) are significant air pollutants that contribute to the formation of ozone and secondary organic aerosols, thus impacting air quality and human health. A study in a coastal suburban area of Hong Kong analyzed VOCs using proton-transfer reaction time-of-flight mass spectrometry (PTR-ToF-MS) and identified 83 species, with oxygenated VOCs (OVOCs) being the most abundant (77.4%). The study revealed seasonal and diurnal variations in VOC concentrations and highlighted the importance of OVOCs in photochemical pollution.

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.

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.
