We studied chemical compositions and chromophores of brown carbon aerosol from combustion emission before and after photooxidation using an oxidative flow reactor. The chromophore and chemical composition of brown carbon were determined by excitation-emission spectroscopy and mass spectrometry. This work helps to get a better understanding of evolution process of the chromophores from primary combustion emissions during the real atmospheric transportation.

This study characterized the changes in chloride depletion under the influence of alkaline species, and further analyzed subsequent formation of corresponding organic chlorinated compounds using high-resolution mass spectrometry. Results demonstrated that the weakening effect of organic amine on chloride depletion is more pronounced than that of NH3 due its stronger alkalinity and nucleation ability. This further enhances our understanding of the mechanism influencing chloride depletion.

This work examines NH3 effects on photochemical oxidation of mixed anthropogenic and biogenic volatile organic compounds (VOC) under high-NOx conditions. NH3 promotes nucleation and accelerates secondary organic aerosol (SOA) formation. NH3 enhances carbonyls, strengthens SOA formation via acid-base and radical reactions, and suppresses highly oxygenated organic molecules. Results improve understanding of SOA formation in complex emissions, aiding air quality forecasting.

This study reveals that summer aerosols over the Bohai and Yellow Seas are mainly influenced by coastal emissions. Despite a high proportion of marine air masses, molecular and isotopic analyses of aerosols show strong terrestrial characteristics. Biomass burning contributes 60–80 % of carbonaceous aerosols, while marine sources account for only ~ 20 %. The findings highlight that controlling coastal emissions within ~ 260 km is crucial for mitigating marginal sea pollution.

The critical role of Criegee intermediates (CIs) in the myrcene ozonolysis was elucidated through the combined approach of matrix isolation Fourier transform infrared spectroscopy and smog chamber experiments. Distinct mechanisms of different-sized CIs in secondary organic aerosol formation were proposed, and a synergistic effect between RO2 autoxidation and CIs oligomerization was identified. This study provided new insights into the ozonolysis process from the Criegee chemistry perspective.

To explore how anthropogenic activities affect HONO formation, we conducted comprehensive observations in Beijing. During clean periods with a 53 % drop in Traffic Performance Index, HONO, CO, and NO2 levels decreased by 2–3 times compared to polluted periods. Emission reduction simulations showed that a 50 % NOx reduction could lower HONO by up to 46.3 %, indicating that reducing anthropogenic activities significantly suppresses HONO formation and provides direct evidence for pollution control.

Authentic aerosols emitted from residential wood stoves and open burning processes are only slightly oxidized by ozone in the atmosphere. Under dry conditions, the reaction does not proceed to completion, while under high humidity conditions, the reactivity proceeds further. These results indicate that the reactivity with ozone is likely impacted by aerosol phase state (e.g., aerosol viscosity).

The daily concentrations of Polycyclic aromatic hydrocarbons (PAHs), oxygenated PAHs (OPAHs), and nitrated phenols (NPs) in PM2.5 were all increased during the heating season. Biomass burning was identified to be the primary source of these aromatic compounds, particularly for PAHs. Phenol and nitrobenzene are two main primary precursors for 4NP, with phenol showing lower reaction barriers. P-Cresol was identified as the primary precursor for the formation of 4-methyl-5-nitrocatechol.

Our study analyzes real-time emissions of organic vapors from solid fuel combustion. Using the mass spectrometer, we tested various fuels, finding higher emission factors for organic vapors from wood burning. Intermediate-volatility organic compounds constituted a significant fraction of emissions in solid fuel combustion. Statistical tests identified unique potential markers. Our insights benefit air quality, climate, and health, aiding accurate emission assessments.

As a key source of hydroxyl (OH) radical, nitrous acid (HONO) has attracted much attention for its important role in the atmospheric oxidant capacity (AOC) increase. In this study, we made a comparison of the ambient levels, variation patterns, sources, and formation pathway in the warm season on the basis of continuous intensive observations at an urban site of Beijing. This work highlights the importance of HONO for the AOC in the warm season.

The photolysis rate constant of particulate nitrate for HONO production (JNO3−–HONO), derived from PM2.5 samples collected at five representative sites in China, exhibited a wide range of variation. A parameterization equation relating JNO3−–HONO to OC/NO3− has been established and can be used to estimate JNO3−–HONO in different environments. Our work provides an important reference for research in other regions of the world where aerosol samples have a high proportion of organic components.

The nitrous acid (HONO) budget was validated during a COVID-19 lockdown event. The main conclusions are (1) HONO concentrations showed a significant decrease from 0.97 to 0.53 ppb during lockdown; (2) vehicle emissions accounted for 53 % of nighttime sources, with the heterogeneous conversion of NO2 on ground surfaces more important than aerosol; and (3) the dominant daytime source shifted from the homogenous reaction between NO and OH (51 %) to nitrate photolysis (53 %) during lockdown.

Nitrated aromatic compounds (NACs) and oxygenated derivatives of polycyclic aromatic hydrocarbons (OPAHs) in PM2.5 were examined from an urban area in Beijing during the autumn and winter. The OPAH and NAC concentrations were much higher during heating than before heating. They majorly originated from the combustion of biomass and automobile emissions, and the secondary generation was the major contributor throughout the whole sampling period.

Aromatic acids can be transferred from seawater to the atmosphere through bubble bursting. The air–sea transfer efficiency of aromatic acids was evaluated by simulating SSA generation with a plunging jet. As a whole, the transfer capacity of aromatic acids may depend on their functional groups and on the bridging effect of cations, as well as their concentration in seawater, as these factors influence the global emission flux of aromatic acids via SSA.

In this study, the interactions between α-pinene and marine emission dimethyl sulfide (DMS) are investigated. It is found that the yield of secondary organic aerosol initially increases and then decreases with the increasing DMS/α-pinene ratio. This trend can be explained by OH regeneration, acid-catalyzed reactions, and the change in OH reactivity, etc. These findings can improve our understanding of atmospheric processes in coastal areas.

This study explores the pH effect on the reaction of dissolved SO2 with selected organic peroxides. Results show that the formation of organic and/or inorganic sulfate from these peroxides strongly depends on their electronic structures, and these processes are likely to alter the chemical composition of dissolved organic matter in different ways. The rate constants of these reactions exhibit positive pH and temperature dependencies within pH 1–10 and 240–340 K ranges.

In this study, we have investigated the distinct impacts of humidity on the ozonolysis of two structurally different monoterpenes (limonene and Δ3-carene). We found that the molecular structure of precursors can largely influence the SOA formation under high RH by impacting the multi-generation reactions. Our results could advance knowledge on the roles of water content in aerosol formation and inform ongoing research on particle environmental effects and applications in models.

SO2 significantly promotes particle formation during cyclooctene ozonolysis. Carboxylic acids and their dimers were major products in particles formed in the absence of SO2. SO2 can induce production of organosulfates with stronger particle formation ability than their precursors, leading to the enhancement in particle formation. Formation mechanisms and structures of organosulfates were proposed, which is helpful for better understanding how SO2 perturbs the formation and fate of particles.

We presented yields and compositions of Si-containing SOAs generated from the reaction of cVMSs (D3–D6) with OH radicals. NOx played a negative role in cVMS SOA formation, while ammonium sulfate seeds enhanced D3–D5 SOA yields at short photochemical ages under high-NOx conditions. The aerosol mass spectra confirmed that the components of cVMS SOAs significantly relied on OH exposure. A global cVMS-derived SOA source strength was estimated in order to understand SOA formation potentials of cVMSs.

Ozone formation is enhanced by higher OH concentration and higher temperature but is influenced little by SO2. SO2 can largely enhance the particle formation. Organo-sulfates and organo-nitrates are detected in the formed particles, and the presence of SO2 can promote the formation of organo-sulfates. The results provide a scientific basis for systematically evaluating the effects of SO2, OH concentration, and temperature on the oxidation of mixed organic gases in the atmosphere.

This study added six potential HONO sources to the WRF-Chem model, evaluated their impact on HONO and O3 concentrations, including surface and vertical concentrations. The simulations extend our knowledge on atmospheric HONO sources, especially for nitrate photolysis. The study also explains the HONO difference in O3 formation on clean and hazy days, and reveals key potential HONO sources to O3 enhancements in haze-aggravating processes with a co-occurrence of high PM2.5 and O3 concentrations.

Short summary
We investigated the effect of SO2 under different humidities on optical properties of toluene-derived SOA under four conditions with CRDs and PAX at 532 and 375 nm, respectively. Our results showed that SO2 under different humidities can change the refractive complex index of toluene SOA by influencing the multiphase processes and altering the aerosol chemical compositions. Different atmospheric conditions could affect the properties of toluene SOA, as well as the global radiative balance.
