The properties and fate of individual airborne particles can be significantly different, leading to distinct environmental impacts (e.g., climate and human health). While many instruments only analyze an ensemble of these particles, single-particle Raman spectroscopy enables unambiguous characterization of individual particles. This paper comprehensively reviews the applications of such a technique in studying atmospheric particles, especially for their physicochemical processing.

Indoor combustion sources are an important but still poorly understood cause of indoor particle pollution. Using chamber experiments, we studied a widely used incense-burning practice and found that it produces ultrafine-rich particles with strong oxidative activity. We also showed that the burning material, ignition charcoal, and ozone exposure affect how these particles form and change. This work highlights the important role of indoor combustion sources in shaping indoor particle pollution.

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.

The viscosity of ammonium nitrate–sucrose–H2O was quantified with three methods ranging from liquid to solid state depending on the relative humidity. Moreover, the corresponding estimated internal aerosol mixing times remained below 1 h for most tropospheric conditions, making equilibrium partitioning a reasonable assumption.

Our research on city bus emissions reveals that alternative fuels (compressed natural gas and biofuels) reduce fresh particle emissions compared to diesel. However, all fuels lead to secondary air pollution. Aiming at guiding better environmental policies, we studied 76 buses using advanced emission measurement techniques. This work sheds light on the complex effects of bus fuels on urban air quality, emphasizing the need for comprehensive evaluations of future transportation technologies.

Incense burning is common in Asia, posing threats to human health and air quality. However, less is known about its emissions and health risks. Full-volatility organic species from incense-burning smoke are detected and quantified. Intermediate-volatility volatile organic compounds (IVOCs) are crucial organics accounting for 19.2 % of the total emission factors (EFs) and 40.0 % of the secondary organic aerosol (SOA) estimation, highlighting the importance of incorporating IVOCs into SOA models.

In this study, we found that the photolysis of sodium nitrate leads to a much quicker decay of free amino acids (FAAs, with glycine as an example) in the particle phase than ammonium nitrate photolysis, which is likely due to the molecular interactions between FAAs and different nitrate salts. Since sodium nitrate likely co-exists with FAAs in the coarse-mode particles, particulate nitrate photolysis can possibly contribute to a rapid decay of FAAs and affect atmospheric nitrogen cycling.

Research into sulfate and nitrate formation from co-uptake of NO2 and SO2, especially under irradiation, is rare. We studied the co-uptake of NO2 and SO2 by NaCl droplets under various conditions, including irradiation and dark, and RHs, using Raman spectroscopy flow cell and kinetic model simulation. Significant nitrate formation from NO2 hydrolysis can be photolyzed to generate OH radicals that can further react with chloride to produce reactive chlorine species and promote sulfate formation.

This study reveals the sulfate formation in photosensitized particles from biomass burning under UV and SO2, of which the relative atmospheric importance in sulfate production was qualitatively compared to nitrate photolysis. On the basis of single-particle aerosol mass spectrometry measurements, the number percentage of sulfate-containing particles and relative peak area of sulfate in single-particle spectra exhibited a descending order of 3,4-dimethoxybenzaldehyde > vanillin > syringaldehyde.

We compared non-phenolic and phenolic methoxybenzaldehydes as photosensitizers for aqueous secondary organic aerosol (aqSOA) formation under cloud and fog conditions. We showed that the structural features of photosensitizers affect aqSOA formation. We also elucidated potential interactions between photosensitization and ammonium nitrate photolysis. Our findings are useful for evaluating the importance of photosensitized reactions on aqSOA formation, which could improve aqSOA predictive models.

Incense burning is a common religious ritual, especially in Asian and African communities, with massive particles emitted. While previous research mainly focused on the chemical compositions and potential health impacts of fresh incense particles, our work reveals that nitrate, accompanied by SOA, can rapidly form in incense-burning particles upon photochemical oxidation in the atmosphere. This finding could deepen our understanding of air pollution caused by religious activities.

The number of condensed phases in mixtures of different secondary organic aerosol (SOA) types determines their impact on air quality and climate. Here we observe the number of phases in individual particles that contain mixtures of two different types of SOA. We find that SOA mixtures can form one- or two-phase particles, depending on the difference in the average oxygen-to-carbon (O / C) ratios of the two SOA types that are internally mixed within individual particles.

Information on the viscosity of secondary organic aerosols is needed when making air quality, climate, and atmospheric chemistry predictions. Viscosity depends on temperature, so we developed a new method for measuring the temperature-dependent viscosity of small samples. As an application of the method, we measured the viscosity of farnesene secondary organic aerosol at different temperatures.

The contribution of cooking emissions to organic aerosols may exceed that of motor vehicles. However, little is known about how cooking-generated aerosols evolve in the outdoor environment. In this paper, we present a numerical study of the dispersion of cooking emissions. For plausible choices of the emission strength, cooking can yield much higher concentrations than traffic. This has important implications for public health and city planning.

Biomass burning (BB) is a global phenomenon that releases large quantities of pollutants such as phenols and aromatic carbonyls into the atmosphere. These compounds can form secondary organic aerosols (SOAs) which play an important role in the Earth’s energy budget. In this work, we demonstrated that the direct irradiation of vanillin (VL) could generate aqueous SOA (aqSOA) such as oligomers. In the presence of nitrate, VL photo-oxidation can also form nitrated compounds.

We studied the effect of (NH4)2SO4 on the immersion freezing of non-mineral dust ice-nucleating substances (INSs) and mineral dusts. (NH4)2SO4 had no effect on the median freezing temperature of 9 of the 10 tested non-mineral dust INSs, slightly decreased that of the other, and increased that of all the mineral dusts. The difference in the response of mineral dust and non-mineral dust INSs to (NH4)2SO4 suggests that they nucleate ice and/or interact with (NH4)2SO4 via different mechanisms.

Short summary
The viscosity of erythritol, a tetrol found in aerosol particles, is highly uncertain. To help resolve this uncertainty, we measured the viscosities of
erythritol–water particles using rectangular-area fluorescence recovery after photobleaching and aerosol optical tweezers techniques. These results
should help improve the understanding of the viscosity of secondary organic aerosol particles. In addition, we present an intercomparison of techniques
for measuring the viscosity of particles.
The viscosity of erythritol, a tetrol found in aerosol particles, is highly uncertain. To help...
