Summary: This study evaluated the antioxidant capacity of plant extracts and chemical compounds by generating hydroxyl radicals using different systems. The results showed that the EC50 values for the antioxidant activity did not follow a specific order in the different systems, possibly due to the interactions between phosphate buffer and quinolinic acid with the antioxidants and iron-coordinating ligands in the plant extracts.

Summary: The study found that vehicle brake wear is the main source of airborne magnetite in the roadside environment in the UK, accounting for 68%-85%. In comparison, diesel and petrol engine emissions account for 7%-12% and 2%-4% respectively, while background dust contributes around 6%-10%. The high magnetite content in vehicle brake wear may pose potential risks to human cardiovascular and neurological health.

Summary: Elevated levels of particulate matter in urban atmospheres pose a major environmental challenge. Biomonitoring methods, such as analyzing spider webs, can help to identify sources of PM, including brake wear, abrasion of tram/train tracks, and geogenic particles. Statistical analyses reveal the significant contributions of different sources and emphasize the non-exhaust particles associated with road traffic.

Summary: This study reveals that in the Eastern Mediterranean Region, the main sources of ambient particulate matter are secondary aerosols and dust, as well as a variety of mixed sources including traffic, industry, biomass burning, and sea salt. Iran has the highest number of studies on specific sources of PM, while several countries in the region lack research on this topic.

Summary: This study investigated the sources of PM10 and the impact of atmospheric secondary processes on aerosol particle composition in a high-altitude site in southern Europe during summer 2021. The results identified Saharan dust, advection from the urbanized valley, local combustion, smoke from a fire-event, and aerosol from regional recirculation as the main sources of PM10. The sources of PM were associated with synoptic meteorological conditions and circulation patterns typical of mountainous areas. Despite the identification of a local pollution source, its contribution to PM10, OC, and EC was minimal. The findings highlight the significant influence of long-range transport of anthropogenic aerosols on the aerosol chemical composition at this remote site.

Summary: This paper reviews global studies conducted in the past 6 years on the associations between source-specific PM exposure and health effects, highlighting the application of source apportionment technology in epidemiological studies. The findings reveal that PM emitted from different sources contribute differently to health effects and that these effects vary across regions. The paper also discusses the effects of secondary aerosols, consistency of source and its marker constituents in health outcomes, exposure error, spatial misclassification of source exposure, and future applications of source apportionment technologies in epidemiological studies.

Summary: This study focused on the photoaging of PM2.5 in the aqueous phase, finding a seasonal variation in production rate (r(center dot OH)) and hydroxyl radicals ((OH)-O-center dot), with lower values in winter and spring extracts and higher values in summer extracts. The photobleaching extent of the extracts was correlated with r(center dot OH), indicating non-(OH)-O-center dot processes took place. The half-life of compounds in the atmospheric aqueous phase was between 1.9 and 434 h based on measurements of hydroxyl radicals and singlet oxygen.

Summary: There have been relatively few measurements of the OH radical in indoor environments despite its importance outdoors. Elevated concentrations of OH were observed near a window during cooking events, in addition to elevated mixing ratios of HONO, VOCs, and NOX. The measured OH concentrations were underestimated by a chemical model, even during periods of direct sunlight, indicating incomplete understanding of oxidation in indoor environments.

Summary: The call for a paradigm change in toxicology initiated by the United States National Research Council in 2007 highlights the importance of human-relevant alternative methods for toxicological hazard assessment. This review article discusses critical organs such as skin, brain, and lungs in terms of their functions in health and disease, emphasizing the need for more complex organotypic models. Innovative technologies like organs-on-a-chip and genome editing are paving the way for a shift in toxicological paradigm towards more advanced and human-specific approaches.

Summary: Research on the effects of orally ingested engineered nanomaterials (ENMs) emphasizes the importance of developing and utilizing in vitro models. By studying four different in vitro models, the cytotoxic properties of polyvinylpyrrolidone-capped silver and titanium dioxide can be observed. Adverse responses were only observed in monoculture models, while no adverse effects were found in more complex transwell cultures and in vivo murine tissues.

Summary: The results indicate that surface Cu plays a major role in the surface reactivity of CNPs, while Fe has a minor role. At the same time, Cu increases the cytotoxicity of CNPs and their ability to induce oxidative stress and DNA damage. In contrast, surface Fe increases the release of pro-inflammatory cytokines by macrophages. Overall, these results confirm the role of Cu and Fe in PM toxicity and suggest that the total metals content in PM might be a better indicator of pathogenicity than water-soluble metals.

Summary: The effects of four model ENMs on the gut microbiome of mice were examined under a realistic exposure scenario. The ENMs did not significantly impact the diversity of the gut microbiome, but SiO2 exposure led to a decrease in Actinobacteria abundance and Ag exposure increased the relative abundance of Roseburia. Sex-related differences in beta-diversity were observed, highlighting the importance of considering sex and microbial composition in ENM exposure studies. Further research is needed to understand the relevance of ENM-specific effects on key taxa for gut homeostasis and health.

Summary: The adverse effects of air pollutants on the respiratory and cardiovascular systems are well-known, but recent studies have found that they also have negative effects on the neurological system and cognitive function. Ultrafine particles (UFPs) play a key role in these effects, but there is still limited understanding about the smallest fraction and semivolatile compounds. The TUBE project aims to increase knowledge about harmful UFPs and semivolatile compounds, provide information for better emission legislation, and assess the impact of air pollution on the brain and its removal.

Summary: Due to the widespread presence of environmental MNPs, inhalation and ingestion by humans is highly likely, but the health effects remain largely unknown. This study established THP-1 cells with or without NLRP3 to investigate the potential of MNPs to activate the NLRP3 inflammasome. The results suggest that most MNPS do not directly activate the NLRP3 inflammasome, but specific MNP types may still possess pro-inflammatory potential.

This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
