Summary: This study aimed to determine the relative contribution of different species of PM2.5 exposure to perturbed metabolic pathways. Results showed that specific PM2.5 species were associated with inflammation, oxidative stress, immunity, and nucleic acid damage and repair in plasma metabolites. These findings highlight the importance of considering specific sources of PM2.5 exposure in understanding its impact on metabolic pathways.

Summary: Oxidative stress in cells is caused by an imbalance between oxidant production and the antioxidant system's ability to detoxify reactive products. This stress can lead to genotoxic damage, mutation, and play a role in carcinogenesis. Particulate matter (PM) air pollution has been identified as a cancer risk factor, and evidence suggests that PM-induced oxidative stress can contribute to various events promoting carcinogenesis. This review emphasizes the importance of studying the oxidative and genotoxic mechanisms associated with PM in malignant cell transformation and calls for more accurate approaches to assess its carcinogenic potential.

Summary: Air pollution caused by particulate matter is a major threat to human health, especially in large cities. The size, composition, and toxicity of these particles vary. Ultrafine particles have a greater impact on human health as they can enter the lungs and vital organs, leading to diseases. In addition, particulate matter pollution is associated with respiratory conditions, genotoxicity, mutagenicity, and carcinogenicity.

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: 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 describes the urban characteristics associated with the sources of PM2.5 chemical components in the United States. It found that higher proportions of Black individuals and lower socioeconomic status were associated with higher levels of PM2.5. The associations between ZIP code characteristics and source-attributed PM2.5 levels were generally greater in Western states. These findings provide valuable information for air quality improvement strategies.

Summary: Organic aerosols in PM2.5 were analyzed in Zouk Mikael and Fiaa, Lebanon over a one-year period, showing higher concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) at Zouk Mikael than Fiaa, attributed to the presence of a power plant. Phthalates were identified for the first time in Lebanon with high concentrations at both sites. The study suggested strong anthropogenic influences on the aerosols in both locations, with different patterns observed between winter and summer seasons.

Summary: Air pollution is a significant issue for human health, leading to over 7 million premature deaths each year from indoor and outdoor pollution. Exposure to particulate matter is associated with adverse health effects in the short and long term. Evaluating the health risks caused by exposure to contaminants in particulate matter is challenging due to the presence of multiple pollutants and the multiple causes of observed diseases. This review discusses advanced methods for assessing cancer and non-cancer risks from exposure to specific contaminants in particulate matter, including ingestion, inhalation, and dermal contact, as well as different age categories of the population.

Summary: The chemical profiles of PM2.5 emitted from different sources including a non-road diesel generator, wood burning, and cooking activities were analyzed. The main component in the PM2.5 from all sources was carbonaceous matter, with varying contributions from different sources and specific markers identified. Water-soluble ions and elemental content also varied between sources. These findings are important for source identification and apportionment methods.

Summary: The study investigates the efficacy of imidazolium biobased Zwitterionic Ionic Liquids (ZILs) in enhancing copper phytoavailability from garden and vineyard soils. Different soil modalities with and without ZIL amendment were designed, and copper/ZIL molar ratio was rationalized based on molecular modeling. The results showed higher copper accumulation in shoots for ZIL amended vineyard soils compared to garden soils, and ZIL mainly existed in Cu(II)-ZIL4 complexes. The chemical composition of shoots and enzymatic hydrolysis performance were influenced by the presence of free copper and/or ZIL in the soils. The ecotoxicity assessment indicated no significant toxicity from the copper and ZIL remaining in the soils. ZIL amendment in copper-contaminated soil showed promise in promoting phytoremediation plant valorization.
