Summary: The study shows that the oxidative potential (OP) of PM in Lin'an remains relatively high in winter and summer, with PM1 contributing over 60% to the OP of PM2.5. There are significant seasonal variations in the OP of PM, with OPDTTv being higher in winter due to high PM mass concentration, while OPAAv is slightly higher in summer due to photochemical reactions. Local emissions play a larger role in affecting PM health effects in summer, while long-distance transport from other regions is more influential in winter.

Summary: This study investigates the diurnal and seasonal variations of water-soluble ions in fine particles in an area predominantly affected by traffic emissions in Besiktas, Istanbul. The concentrations of these ions vary with seasons and are influenced by different sources. Sulfate aerosol mainly originates from residential heating and shipping emissions, while the formation of ammonium nitrate is more likely than ammonium sulfate.

Summary: Identifying risk drivers is crucial for air pollution control, and biological effect-directed analysis is the most discussed method for linking chemical identification and human health. The water-soluble organic matter in PM2.5 plays a significant role in human health but is challenging to identify chemically. Understanding the structural characteristics and pollution sources of key toxic components is the optimal approach to address this issue.

Summary: A novel two-stage semi-dry electrostatic precipitator (SDEP) was successfully developed to monitor atmospheric PM2.5 water-soluble inorganic ions (WSIIs) with high collection efficiency and accuracy. The SDEP showed high collection efficiency for particles of various sizes and high ion recovery rates for Na+, NH4+, SO42-, and NO3-. When coupled with parallel plate wet denuder (PPWD) and ion chromatography (IC), the PPWD-SDEP-IC system demonstrated good agreement with other samplers for precursor gases and PM2.5 WSIIs concentrations.

Summary: The sensing application of citrate-functionalized gold nanoparticles (AuNPs) for the determination of L-cysteine in food and water samples was successfully demonstrated in this study. The aggregation of AuNPs enhanced the signal intensity of L-cysteine, resulting in effective absorption of electromagnetic radiation in the IR region for molecular vibration. The theoretical investigation and experimental results confirmed the interaction between AuNPs and L-cysteine molecules, leading to a shift in plasmon bands and aggregation of particles.

Summary: An in-depth study of aerosol and precipitation ion chemistry in Moscow urban background atmosphere was conducted to fill the gap in seasonal-dependent ionic data. The literature on atmospheric pollution in this megacity is still limited, despite its unique climatic characteristics. The results showed that inorganic ions constitute a significant fraction of PM10, with higher proportions in autumn than in summer. Secondary inorganic aerosol was found to dominate over other inorganic ion species. Sodium and calcium ions exhibited the most variability among seasons. The chloride depletion phenomenon was most pronounced in summer.

Summary: Excitation-emission matrix (EEM) fluorescence spectroscopy was used to study the fluorescence properties of solvent-extractable organic components in sub-micrometer forest aerosols in Hokkaido, Japan. The results showed that the fluorescence volume normalized by the mass concentration (NFV) and the fluorescence volume (FV) of water-insoluble organic matter (WISOM) were higher than other fractions, and correlated with organic compounds containing O and N. The analysis of fluorescence characteristics can provide insights into the types and sources of aerosol components, which is important for the detection of primary biological aerosol particles (PBAP).

Summary: This literature review summarizes toxicological and epidemiological studies of ultrafine particles (UFPs) from different transport modes, including vehicle exhaust, non-exhaust, shipping, aviation, and rail. The results suggest that particles from both fossil and biodiesel sources exhibit toxic effects, with impacts on the lung, cardiovascular system, and brain. Further research is needed to better understand the relative toxicity of UFPs from different transport modes and their implications for health risk assessment.

Summary: During the summer and winter periods of 2019-2020, we sampled fine mode ambient aerosols in three Himalayan glacial regions and evaluated their aerosol optical properties and radiative forcing efficiencies. We found that the highest absorption occurred in the near ultraviolet-visible wavelength range, with the central Himalayan glacial region showing the highest absorption. Black carbon had a greater contribution to light attenuation across a wide wavelength range, while brown carbon dominated absorption in the near UV-visible wavelengths. Our findings contribute to the understanding of carbonaceous aerosols and their impact on Himalayan glacier regions.
