This study represents the inaugural instance of simultaneous comprehensive characterization of organosulfates and nitrogen-containing organic compounds (detected in both ESI+ and ESI- modes) in PM2.5 in tropical marine areas with minimal anthropogenic pollution. The overall results provide the observation-based molecular evidence that marine emissions may play a significant role in the formation of aromatic and aliphatic organic sulfur and nitrogen aerosols in the South China Sea.

Previous measurement–model comparisons of atmospheric isoprene levels showed a significant unidentified source of isoprene in some northern Chinese cities during winter. Here, the first combination of large-scale observations and field combustion experiments provides novel insights into biomass burning emissions as a significant source of isoprene-derived organosulfates during winter in northern cities of China.

This study investigates the characteristics of aminiums and ammonium in PM2.5 on clean and polluted winter days in 11 Chinese cities, highlighting the possibility of the competitive uptake of ammonia versus amines on acidic aerosols or the displacement of aminiums by ammonia under high-ammonia conditions. The overall results deepen the understanding of the spatiotemporal differences in aminium characteristics and formation in China.

In this study, 130 OS species were quantified in ambient fine particulate matter (PM2.5) collected in urban and suburban Shanghai (East China) in the summer of 2021. The daytime OS formation was concretized based on the interactions among OSs, ultraviolet (UV), ozone (O3), and sulfate. Our finding provides field evidence for the influence of photochemical process and anthropogenic sulfate on OS formation and has important implications for the mitigation of organic particulate pollution.

The concentrations and δ15N isotopic values of CAAs (combined amino acids) in surface soil and plants from the Gobi Desert, as well as in PM2.5 samples from four cities in Northern China, were measured. CAAs transported by Gobi dust were rich in alanine, glycine and glutamic acid. Glycine and leucine in Gobi Desert sources exhibited δ15N depletion by more than 6 ‰ compared to their values in urban PM2.5. Substantial protein-N deposition can be transported by the Gobi Desert to northern China over brief periods.

Isoprene-derived secondary organic aerosol (iSOA) is a major type of biogenic SOA in the atmosphere, yet its response to long-term anthropogenic emission reductions remains poorly understood. Here, combing field observations and model simulations, we characterized the abundance, trend, and underlying drivers of iSOA in Shanghai, China during 2015–2021, which will advance our understandings of the formation and impacts of biogenic SOA under rapidly evolving emission scenarios in urban regions.

Through a comprehensive year-long analysis of major polar organic compounds in PM2.5, we elucidate the complex composition and sources of organic aerosols (OAs) within the urban environment of Nanchang, China. Given the significant health and environmental impacts of PM2.5, our research provides critical insights into the contributions of primary emissions and secondary formation processes to urban OA, and confirm the sources and the influencing factors of OA during pollution episodes.

This study established a refined isotopic fingerprint of NOx sources in local Tianjin, which included previously uncharacterized sources in China. Results shown that the representative nature and region-specific characteristics of isotopic fingerprints for six categories of NOx sources in Tianjin. A reasonable source-resolved structure of NO3– could obtained by MixSIAR model using the δ15N values of NOx source established in this study, suggest the important of the refined isotopic fingerprint.

Acylperoxy radicals (RO2) are key intermediates in the atmospheric oxidation of organic compounds, yet our knowledge of their identities and chemistry remains poor. Using direct measurements and kinetic modeling, we identify the composition and formation pathways of acyl RO2 and quantify their contribution to highly oxygenated organic molecules during α-pinene ozonolysis, which will help to understand oxidation chemistry of monoterpenes and sources of low-volatility organics in the atmosphere.

New particle formation and growth in polluted environments are not fully understood despite intensive research. We applied a cluster dynamics–multicomponent sectional model to simulate the new particle formation events observed in Beijing, China. The simulation approximately captures how the events evolve. Further diagnosis shows that the oxygenated organic molecules may have been under-detected, and modulating their abundance leads to significantly improved simulation–observation agreement.

The air pollution associated with fine particles and secondary organic aerosol is not weakened by the application of mist cannon trucks but rather is aggravated. Our results provide not only new insights into the formation processes of aerosol water-soluble organic compounds associated with the water mist sprayed by mist cannon trucks in the road atmospheric environment but also crucial information for the decision makers to regulate the operation of mist cannon trucks in many cities in China.

Sugars and amino acids are major classes of organic components in atmospheric fine particles and play important roles in the atmosphere. To identify their sources in different regions, the concentrations and compositions of sugar amino acids in fine particles were analysed. Our findings suggest that combining specific sugar tracers and chemical profiles of combined amino acids in local emission sources can identify various source characteristics of primary sources.

Particulate nitrate plays an important role in wintertime haze pollution in eastern China, yet quantitative constraints on detailed nitrate formation mechanisms remain limited. Here we quantified the contributions of the heterogeneous N2O5 hydrolysis (66 %) and gas-phase OH + NO2 reaction (32 %) to nitrate formation in this region and identified the atmospheric oxidation capacity (i.e., availability of O3 and OH radicals) as the driving factor of nitrate formation from both processes.

Organosulfates (OSs) are important constituents and tracers of secondary organic aerosols (SOAs) in the atmosphere. Here we characterized the OS species in ambient aerosols in Shanghai, China. We find that the contributions of OSs and SOAs to organic aerosols have increased in recent years and that OS production was largely controlled by the oxidant level (Ox), particularly in summer. We infer that mitigation of Ox pollution can effectively reduce the production of OSs and SOAs in eastern China.

Amino acids (AAs), as important organic nitrogen compounds, play key roles in the nitrogen cycles, climate change and public health. The sources and transformation of AAs in two size-segregated aerosol particles were explored. This study presents the first isotopic evidence that the sources of AAs for fine and coarse aerosol particles may be similar. And the potentially significant role of bacterial degradation processes in aerosol protein degradation state was suggested.

Short summary
The abundance, potential precursors, and main formation mechanisms of nitrogen-containing organic compounds (NOCs) in PM2.5 during winter were compared among cities with different energy consumption patterns. The aerosol NOC pollution during winter in China is closely associated with the intensity of precursor emissions and the aqueous-phase processes. Our results highlight the importance of emission reduction strategies in controlling aerosol NOCs pollution during winter in China.
