This study investigates the molecular characteristics and chemical evolution of organic aerosol (OA) in contrasting urban and seaside environments by offline Chemical Ionization Mass Spectrometry. Urban OA was enriched in aromatic species, while seaside OA featured aliphatic and highly oxidized compounds. Marine-influenced humid air masses, combined with active photochemical conditions, promoted aqueous-phase OA formation, leading to higher oxidation states, particularly at the seaside site.

Box modeling with the Master Chemical Mechanism (MCM) was used to explore summertime peroxyacetyl nitrate (PAN) formation and its link to aerosol pollution under high-ozone conditions. The MCM model is effective in the study of PAN photochemical formation and performed better during the clean period than the haze period. Machine learning analysis identified ammonia, nitrate, and fine particulate matter as the top three factors contributing to simulation bias.

Particle uptakes of HCHO and the impacts on PM2.5 and O3 production remain highly uncertain. Based on the investigation of co-occurring wintertime O3 and PM2.5 pollution in a coastal city of southeast China, we found enhanced heterogeneous formation of hydroxymethanesulfonate (HMS) and increased ROx concentrations and net O3 production rates. The findings of this study are helpful to better explore the mechanisms of key precursors for co-occurring PM2.5 and O3 pollution.

Gaseous elemental mercury (GEM) was observed in Southeast China over the period 2012–2020. The observed GEM concentrations showed no distinct inter-annual variation trends. The interpretation rate of transportation and meteorology on GEM variations displayed an increasing trend. In contrast, anthropogenic emissions have shown a decreasing interpretation rate since 2012, indicating the effectiveness of emission mitigation measures in reducing GEM concentrations in the study region.

Field observations and models analysis were carried out in a coastal city to study HCHO formation mechanism and its impacts on photochemistry. HCHO contributed to atmospheric oxidation by around 10 %, reflecting its significance in photochemistry. Disabling HCHO mechanism made net O3 production rates decrease by 31 %, which were dominated by the reductions of pathways relating to radical reactions, indicating the HCHO affected O3 mainly by controlling the efficiencies of radical propagation.

We clarified the seasonal variations of PAN pollution, influencing factors, its mechanisms, and impacts on O3 based on OBM and GAM models. PAN presented inhibition and promotion effects on O3 under low and high ROx levels. Monitoring of PAN and its precursors, and the quantification of its impacts on O3 formation, significantly guide photochemical pollution control. The analysis methods used in this study provide a reference for study of the formation mechanisms of PAN and O3 in other regions.

Based on the OBM-MCM model analyses, the study aims to clarify (1) the pollution characteristics of O3 and its precursors, (2) the atmospheric oxidation capacity and radical chemistry, and (3) the O3 formation mechanism and sensitivity analysis. The results are expected to enhance the understanding of the O3 formation mechanism with low O3 precursor levels and provide scientific evidence for O3 pollution control in coastal cities.

There has been a lack of research into HONO in coastal cities with low concentrations of PM2.5, but strong sunlight and high humidity. Insufficient research on coastal cities with good air quality has resulted in certain obstacles to assessing the photochemical processes in these areas. Furthermore, HONO contributes to the atmospheric photochemistry depending on the season. Therefore, observations of HONO across four seasons in the southeastern coastal area of China are urgently needed.

Based on field observations of N2O5, we found extremely high nighttime concentrations of N2O5, with a maximum value of 2.52 ppb. Further multiphase box model analysis revealed that the heterogeneous uptake of N2O5 is the most significant nitrate formation pathway in NO2-limited urban areas. Additionally, we further analyzed the reasons for this high N2O5 uptake contribution, and discussed the synergistic reduction of nitrates and O3.

Our study revealed that the nighttime heterogeneous dinitrogen pentoxide (N2O5) uptake process was the major contributor of nitryl chloride (ClNO2) sources, while nitrate photolysis may promote the elevation of daytime ClNO2 concentrations. The rates of alkane oxidation by chlorine (Cl) radical in the early morning exceeded those by OH radical, significantly promoted the formation of ROx and ozone (O3), and further enhanced the atmospheric oxidation capacity levels.

This study uses machine learning to separate marine primary (POA) and secondary organic aerosols (SOA) from a decade of high-resolution data. POA averages 51 % of marine organic aerosols annually, peaking at 63 % in summer. A support vector regression model, validated via fuzzy clustering and Monte Carlo simulations, identifies POA’s seasonal patterns linked to biological activity. We found diverse impacts of marine POA and SOA on the aerosol hygroscopicity and mixing state.

This study presents the first source apportionment of organic aerosol at Mace Head via high-resolution mass spectrometry. Introducing transfer entropy as a novel method reveals that aged organic aerosol originates from both open-ocean ozonolysis and local peat-burning oxidation. Methanesulfonic acid and organic sea spray both mirror phytoplankton activity, with the former closely tied to coccolithophore blooms and the latter linked to diatoms, chlorophytes, and cyanobacteria.

Our field campaigns observed a strong diel pattern of chloroacetic acid as well as a strong correlation between its level and that of reactive chlorine species at a coastal site. Using quantum chemical calculations and box model simulation with an updated Master Chemical Mechanism, we found that the formation pathway of chloroacetic acid involved multiphase processes. Our study enhances understanding of atmospheric organic chlorine chemistry and emphasizes the importance of multiphase reactions.

Secondary organic aerosols (SOAs) from acetone photooxidation in the presence of various seeds were studied to illustrate SOA formation kinetics under ammonia-rich conditions. The oxidation mechanism of acetone was investigated using an observation-based model incorporating a Master Chemical Mechanism model. A higher SOA yield of acetone was observed compared to methylglyoxal due to an enhanced uptake of the small photooxidation products of acetone.

This work systematically explained the nonlinear effect of NOx level on isoprene-SOA mass yield through a series of chamber experiments. We found that the turning point under various oxidants was smaller than previous reported in the presence of OH precursors, which could be attributed to the RO2 pathway competition in nucleation and condensation of low volatile products. The highest SOA yield was at a branching ratio β of 0.5, which can be used as a reference for field campaign and modeling.

The chemical composition and sources of submicron aerosol in the Dublin Port area were investigated over a month-long campaign. Two distinct types of ship emissions were identified and characterised: sulfate-rich plumes from the use of heavy fuel oil with scrubbers and organic-rich plumes from the use of low-sulfur fuels. The latter were more frequent, emitting double the particle number and having a typical V / Ni ratio for ship emission.

We conducted α-pinene photooxidation experiments in an atmospheric chamber at different NOx concentrations. The increased distribution coefficient of the oxidation products between the aerosol and gas phases with NOx was responsible for the increased SOA yields with NOx under low-NOx conditions. We also found the fraction of SOA made up of nitrogen-containing organic compounds (NOCs) increased with NOx.

The chemical composition of atmospheric particles has shown significant changes in recent years. We investigated the potential effects of changes in inorganics on aerosol water uptake and, thus, secondary organic aerosol formation in wintertime haze based on the size-resolved measurements of non-refractory fine particulate matter (NR-PM2.5) in Xi’an, northwestern China. We highlight the key role of aerosol water as a medium to link inorganics and organics in their multiphase processes.

Secondary organic aerosol (SOA) can be produced by various pathways, but its formation mechanisms are unclear. Observations were conducted in the North China Plain during a highly oxidizing atmosphere in summer. We found that fast photochemistry dominated SOA formation during daytime. Two types of aqueous-phase chemistry (nocturnal and daytime processing) take place at high relative humidity. The potential transformation from primary organic aerosol (POA) to SOA was also an important pathway.

The complex interaction between O3 and PM2.5, coupled with the topology of the Fenwei Plain and the evolution of the boundary layer height, highlights the challenges in further reducing particulate pollution in winter despite years of efforts to reduce emissions. Through scenario analysis in a chemical box model constrained by observation, we show the co-benefits of reducing NOx and VOCs simultaneously in reducing ozone and SOA.

This work presents the differences resulting from two techniques (rolling and seasonal) of the positive matrix factorisation model that can be run for organic aerosol source apportionment. The current state of the art suggests that the rolling technique is more accurate, but no proof of its effectiveness has been provided yet. This paper tackles this issue in the context of a synthetic dataset and a multi-site real-world comparison.

Biomass-burning-influenced oxygenated organic aerosol (OOA-BB), formed from the photochemical oxidation and aging of biomass burning OA (BBOA), was resolved in urban Xi’an. The aqueous-phase processed oxygenated OA (aq-OOA) concentration was more dependent on secondary inorganic aerosol (SIA) content and aerosol liquid water content (ALWC). The increased aq-OOA contribution during SIA-enhanced periods likely reflects OA evolution due to the addition of alcohol or peroxide groups

To investigate the physico-chemical properties of aerosol transported from major pollution regions in China, observations were conducted ~200 m above the ground at the junction location of the two key pollution areas. We found that the formation efficiency, oxidation state and production rate of secondary aerosol were different in the transport sectors from different pollution regions, and they were largely enhanced by the regional long-distance transport.

Short summary
Field observations and models analysis were carried out in a coastal city to study HCHO formation mechanism and its impacts on photochemistry. HCHO contributed to atmospheric oxidation by around 10 %, reflecting its significance in photochemistry. Disabling HCHO mechanism made net O3 production rates decrease by 31 %, which were dominated by the reductions of pathways relating to radical reactions, indicating the HCHO affected O3 mainly by controlling the efficiencies of radical propagation.

We clarified the seasonal variations of PAN pollution, influencing factors, its mechanisms, and impacts on O3 based on OBM and GAM models. PAN presented inhibition and promotion effects on O3 under low and high ROx levels. Monitoring of PAN and its precursors, and the quantification of its impacts on O3 formation, significantly guide photochemical pollution control. The analysis methods used in this study provide a reference for study of the formation mechanisms of PAN and O3 in other regions.

Based on the OBM-MCM model analyses, the study aims to clarify (1) the pollution characteristics of O3 and its precursors, (2) the atmospheric oxidation capacity and radical chemistry, and (3) the O3 formation mechanism and sensitivity analysis. The results are expected to enhance the understanding of the O3 formation mechanism with low O3 precursor levels and provide scientific evidence for O3 pollution control in coastal cities.

There has been a lack of research into HONO in coastal cities with low concentrations of PM2.5, but strong sunlight and high humidity. Insufficient research on coastal cities with good air quality has resulted in certain obstacles to assessing the photochemical processes in these areas. Furthermore, HONO contributes to the atmospheric photochemistry depending on the season. Therefore, observations of HONO across four seasons in the southeastern coastal area of China are urgently needed.

Mercury (Hg) isotopic compositions in aerosols are the mixed results of emission sources and atmospheric processes. This study presents Hg isotopic compositions in PM2.5 from different types of locations and total Hg from offshore surface seawater. The results indicate that atmospheric transformations induce significant mass independent fractionation of Hg isotopes, which obscures Hg isotopic signatures of initial emissions.

Source apportionment of solid-fuel-burning emissions can be complicated by the use of different fuels, stoves, and burning conditions. Here, the organic aerosol mass spectra produced from burning a range of solid fuels in several stoves were compared. This study accounts for the source variability and provides better constraints on the primary factor contributions to the ambient organic aerosol estimations, holding significant implications for public health and policymakers.

Cloud condensation nuclei (CCN) are an important topic in atmospheric studies, especially for evaluating the climate impact of aerosol. Here in this study, CCN closure is studied by using chemical composition based on an aerosol mass spectrometer (AMS) and hygroscopicity growth measurements based on a humidified tandem differential mobility analyzer (HTDMA) at the Mace Head atmospheric research station.

We characterized the seasonal variations in nitrated aromatic compounds (NACs) in composition, sources, and their light absorption contribution to brown carbon (BrC) aerosol in Xi'an, Northwest China. Our results show that secondary formation and vehicular emission were dominant sources in summer (~80 %), and biomass burning and coal combustion were major sources in winter (~75 %), and they indicate that the composition and sources of NACs have a profound impact on the light absorption of BrC

Short summary
Secondary organic aerosol (SOA) simulation remains uncertain, due to the unknown SOA formation mechanisms. Aerosol samples with a 4 h time resolution were collected, along with online measurements of aerosol chemical compositions and meteorological parameters. We found that anthropogenic emissions, atmospheric oxidation capacity and halogen chemistry have significant effects on the formation of biogenic SOA (BSOA). The findings of this study are helpful to better explore the missed SOA sources.
