Short summary
Coal dust, as a non-traditional source, undergoes processes like mining, transportation, handling, and storage, releasing amounts of carbonaceous aerosols that impact the environment and climate. Our investigation the aging of coal dust and water-soluble organic carbon (WSOC) treated with O3, and found that O3 aging increases both carbon emissions and radiative forcing of WSOC. Our research findings are essential for enhancing the understanding of coal dust's effects on air quality and climate.

This study provides laboratory evidence that the photosensitizers in biomass burning extracts can enhance sulfate formation in NaCl particles, primarily by triggering the formation of secondary oxidants under light and air conditions, with a lower contribution of direct photosensitization via triplets.

Short summary
Environmental persistent free radicals (EPFRs) and reactive oxygen species (ROSs) play an active role in the atmosphere. Despite control measures having effectively reduced their emissions, reductions were less than in PM2.5. Emission control measures performed well in achieving Parade Blue, but reducing the impact of the atmosphere on human health remains challenging. Thus, there is a need to reassess emission control measures to better address the challenges posed by EPFRs and ROSs.

The present research unveiled that acidity dominates while transition metal ions harmonize with the light absorption properties of humic-like substances (HULIS). Cu2+ has quenching effects on HULIS by complexation, hydrogen substitution, or electrostatic adsorption, with aromatic structures of HULIS. Such effects are less pronounced if from Mn2+, Ni2+, Zn2+, and Cu2+. Oxidized HULIS might contain electron-donating groups, whereas N-containing compounds might contain electron-withdrawing groups.

This study analyzed PM10 and oxidative potential (OP) in 12 Chinese regions (June 2022–May 2023) using Convolutional Neural Networks and Long Short-Term Memory networks (CNN-LSTM) and Positive Matrix Factorization(PMF). PM10 was higher in the northwest and lower in the northeast, with urban areas showing higher OP. Main sources included dust, biomass burning, traffic emissions, and agricultural activities, with traffic as the key OP contributor.

Short summary
Water-soluble organic compounds (WSOCs) play important roles in atmospheric particle formation, migration, and transformation processes. In this work, size-segregated atmospheric particles were collected in a rural area of Beijing, and 3D fluorescence spectroscopy was used to investigate the optical properties of WSOCs as a means of inferring information about their atmospheric sources. It was found that these data could efficiently reveal the secondary transformation processes of WSOCs.

Short summary
Deep interrogation of water-soluble organic carbon (WSOC) in aerosols is critical and challenging considering its involvement in many key aerosol-associated chemical reactions. This work examined how the chemical structures (functional groups) and optical properties (UV/fluorescence properties) of WSOC were affected by pH and particle size. We found that the pH- and particle-size-dependent behaviors could be used to reveal the structures, sources, and aging of aerosol WSOC.
