Brown carbon (BrC) fractions derived from biomass burning and coal combustion including water- and methanol-soluble organic carbon were comprehensively characterized for their optical and chemical properties, as well as oxidative potential. Moreover, the key components or functional groups that were responsible for the reactive oxygen species (ROS) generation capacity of BrC were also discussed. These findings are useful for estimation of their environmental, climate, and health impacts.

It is important to study the formation characteristics and mechanism of triplet state in aerosols to quantify the effect of chromophore substances on the global climate and atmospheric environmental quality. The result of this study reveals that chromophore substances contributes significantly to aerosol photochemistry and plays an important role in aerosol aging. The global models may need to include those potential effects in the future.

This study investigated the evolution of biomass and coal combustion-derived WSOM during aqueous photochemical process. The results indicate that photochemical aging induces distinct changes in the optical and molecular properties of WSOM and more pronounced alterations were observed during ·OH photooxidation than direct photolysis. Notably, our results also demostrated that atmospheric photooxidation may represent a significant source of BC-like substances.

Molecular-level characteristics of high molecular weight (HMW) and low MW (LMW) humic-like substances (HULIS) were comprehensively investigated, where HMW HULIS had larger chromophores and larger molecular size than LMW HULIS and exhibited higher aromaticity and humification. Electrospray ionization high-resolution mass spectrometry revealed more aromatic molecules in HMW HULIS. HMW HULIS had more CHON compounds, while LMW HULIS had more CHO compounds.

This study provides a comprehensive molecular identification of atmospheric common fluorescent components and deciphers their related formation pathways. The fluorescent components varied in molecular composition, and a dominant oxidation pathway for the formation of humic-like fluorescent components was suggested, notwithstanding their different precursor types. Our findings are expected to be helpful to further studies using the EEM-PARAFAC as a tool to study atmospheric BrC.

A particle-phase O3 oxidation of biomass burning (BB) smoke particles was conducted to investigate the evolution of brown carbon (BrC) therein. The O3 aging induced the decomposition of chromophores and fluorophores. EEM–PARAFAC showed a predominant decomposition of protein-like substances and a gradual increase proportion of humic-like substances for BB BrC during O3 aging. The dynamic spectral behavior of chromophores and functional groups within BrC was further explored by 2D-COS.

We investigated the light absorption, fluorescence, and molecular composition of dissolved organic carbon from the simulated combustion of biomass and coal and vehicle emissions with UV–vis spectra, EEM-PARAFAC, and FT-ICR MS. We observed high light absorption capacity from source emissions, and fluorescence spectra and molecular structures varied by source. We concluded that an EEM- and molecular-composition-based methodology could be helpful in the source apportionment of atmospheric aerosols.

The mixing state of black carbon (BC)-containing particles and the mass scavenging efficiency of BC in cloud were investigated at a mountain site (1690 m a.s.l.) in southern China. The measured BC-containing particles were internally mixed extensively with sulfate, and thus the number fraction of scavenged BC-containing particles is close to that of all the measured particles. BC-containing particles with higher fractions of organics were scavenged relatively less.

We first reported the size-resolved mixing state of oxalate in the cloud droplet residual, the cloud interstitial, and cloud-free particles by single particle mass spectrometry. Individual particle analysis provides unique insight into the formation and evolution of oxalate during in-cloud processing. The data show that in-cloud aqueous reactions dramatically improved the formation of oxalate from organic acids that were strongly associated with the aged biomass burning particles.

A ground-based counterflow virtual impactor coupled with a single-particle aerosol mass spectrometer (SPAMS) was used to assess the mixing state of individual cloud residue particles. Abundant aged EC cloud residues that internally mixed with inorganic salts were found in air masses from northerly polluted areas. K-rich cloud residues significantly increased within southwesterly air masses. This study increases our understanding of the impacts of aerosols on cloud droplets in southern China.

This paper first presents an estimate of the real part of the refractive indices and effective densities of chemically segregated aerosols in China. The results indicate the presence of spherical or nearly spherical shape for the majority of particle types. While sharing refractive index in a narrow range (1.47–1.53), they exhibited a wide range of effective density (0.87–1.51). Detailed relationship between physical and chemical properties benefits future research on visibility and climate.

Short summary
The formation of SOA and sulfate aerosols from the photooxidation of gasoline vehicle exhaust (GVE) when mixing with SO2 was investigated in a smog chamber. We found that the presence of GVE enhanced the conversion of SO2 to sulfate predominantly through reactions with stabilized Criegee intermediates. On the other hand, the elevated particle acidity enhanced the SOA production from GVE. This study indicated that SO2 and GVE could enhance each other in forming secondary aerosols.

Short summary
Thin film formation at the air–water interface from material extracted from atmospheric aerosol was demonstrated, supporting the core–shell morphology. Film thicknesses were approximately 10 Å and 17 Å for urban and remote extracts, respectively. Exposure to gas-phase OH radicals showed fast reactions and short lifetimes of around 1 h. The effect on the Earth's radiative balance indicated that removing half of the film could significantly increase the top-of-atmosphere albedo for urban films.

The metabolic capacity of atmospheric microorganisms after settling into habitats is poorly understood. We studied the molecular composition of exometabolites for cultured typical airborne microbes and traced their metabolic processes. Bacteria and fungi produce highly oxidized exometabolites and have significant variations in metabolism among different strains. These insights are pivotal for assessing the biogeochemical impacts of atmospheric microorganisms following their deposition.

Past atmospheric NH3 pollution in south-eastern Europe was reconstructed by analysing ammonium in an ice core drilled at the Mount Elbrus (Caucasus, Russia). The observed 3.5-fold increase in ice concentrations between 1750 and 1990 CE is in good agreement with estimated past dominant ammonia emissions from agriculture, mainly from south European Russia and Türkiye. In contrast to present-day conditions, the ammonium level observed in 1750 CE indicates significant natural emissions at that time.

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.

We developed a continuous flow analysis system to analyze an ice core from northwestern Greenland and coupled it with an improved refractory black carbon (rBC) measurement technique. This allowed accurate high-resolution analyses of size distributions and concentrations of rBC particles with diameters of 70 nm–4 μm for the past 350 years. Our results provide crucial insights into rBC's climatic effects. We also found previous ice core studies substantially underestimated rBC mass concentrations.

Lignin and Snomax are surface-active macromolecules that show a relationship between increasing concentrations, decreasing surface tension, and increasing ice-nucleating ability. However, this relationship did not hold for agricultural soil extracts collected in the UK and Canada. Hydrophobic interfaces play an important role in the ice-nucleating activity of organic matter; as the complexity of the sample increases, the hydrophobic interfaces in the bulk compete with the air-water interface.

Cooking activities can contribute substantially to indoor and ambient aerosol. We performed a comprehensive study with laboratory measurements cooking 19 different dishes and ambient measurements at two Christmas markets measuring various particle properties and trace gases of emissions in real time. Similar emission characteristics were observed for dishes with the same preparation method, mainly due to similar cooking temperature and use of oil, with barbecuing as an especially strong source.

Hydrogen peroxide (HOOH) is an important oxidant that forms atmospheric sulfate. We demonstrate that illumination of brown carbon can rapidly form HOOH within particles, even under the low sunlight conditions of Fairbanks, Alaska during winter. This in-particle formation of HOOH is fast enough that it forms sulfate at significant rates. In contrast, the formation of HOOH in the gas phase during the campaign is expected to be negligible because of high NOx levels.

The stability during the atmospheric transformation processes is crucial for predicting their environmental fate and assessing associated risks. Here, we conducted field studies and laboratory simulation experiments to reveal the mechanisms, influencing factors and products for XPAHs’ heterogeneous phototransformation. Results revealed that the conversion of XPAHs led to a reduction in environmental risk.

Atmospheric organics are subject to synergistic oxidation by different oxidants, yet the mechanisms of such processes are poorly understood. Here, using direct measurements and kinetic modeling, we probe the nocturnal synergistic-oxidation mechanism of α-pinene by O3 and NO3 radicals and in particular the fate of peroxy radical intermediates of different origins, which will deepen our understanding of the monoterpene oxidation chemistry and its contribution to atmospheric particle formation.

Atmospheric secondary aerosols, composed of organic and inorganic components, undergo complex reactions that impact their phase state. Using molecular spectroscopy, we showed that ammonium-promoted aqueous replacement reaction, unique to these aerosols, is closely linked to phase behavior. The interplay between reactions and aerosol phase state can cause atypical phase transition and irreversible changes in aerosol composition during hygroscopic cycles, further impacting atmospheric processes.

Single-particle mass spectrometry (SPMS) is commonly used to measure the chemical composition and mixing state of aerosol particles. Intercomparison of SPMS instruments was conducted. All instruments reported similar size ranges and common spectral features. The instrument-specific detection efficiency was found to be more dependent on particle size than type. All differentiated secondary organic aerosol, soot, and soil dust but had difficulties differentiating among minerals and dusts.

The climate effects of atmospheric aerosols are insufficiently known, and the properties of aerosols are affected by their surface due to their small size. Organic molecules are important aerosol constituents. We show that the surface composition of aerosols containing organic molecules and water is very different from the bulk. This affects all surface-related properties and processes. Our results demonstrate the importance of accounting for the aerosol surface composition in climate models.

The chemical composition of organic aerosol derived from wood burning emissions under different burning conditions was characterised. Fresh emissions from flaming and smouldering were largely aromatic in nature whereas upon aging the aromatic content decreased. This decrease was greater for smouldering due to the loss of toxic polyaromatic species. Whereas under flaming conditions highly toxic polyaromatic species were produced. These differences present an important challenge for policy.

In this research, we studied the dust-emitting properties of crusts and aeolian ripples from the Mojave Desert. These properties are key to understanding the effect of dust upon climate. We found two different playa lakes according to the groundwater regime, which implies differences in crusts' cohesion state and mineralogy, which can affect the dust emission potential and properties. We also compare them with Moroccan Sahara crusts and Icelandic top sediments.

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.

We provide evidence that light enhances the conversion of SO2 to sulfates on non-photoactive mineral dust, where triplet states of SO2 (3SO2) can act as a pivotal trigger to generate sulfates. Photochemical sulfate formation depends on H2O, O2, and basicity of mineral dust. The SO2 photochemistry on non-photoactive mineral dust contributes to sulfates, highlighting previously unknown pathways to better explain the missing sources of atmospheric sulfates.

Brown carbon (BrC) is related to radiative forcing and climate change. The BrC fraction from residential coal and biomass burning emissions, which were the major source of BrC, was characterized at the molecular level. The CHOS aromatic compounds explained higher light absorption efficiencies of biomass burning emissions compared to coal. The unique formulas of coal combustion aerosols were characterized by higher unsaturated compounds, and such information could be used for source appointment.

Cooking is a major source of particles in urban areas. Previous studies demonstrated that the chemical lifetimes of cooking organic aerosols (COAs) were much shorter (~minutes) than the values reported by field observations (~hours). We conducted laboratory experiments to resolve the discrepancy by considering suppressed reactivity under low temperature. The parameterized k2–T relationships and observed surface temperature data were used to estimate the chemical lifetimes of COA particles.

We measured changes in light absorption during the aqueous oxidation of six phenols with hydroxyl radical (●OH) or an organic triplet excited state (3C*). All the phenols formed light-absorbing secondary brown carbon (BrC), which then decayed with continued oxidation. Extrapolation to ambient conditions suggest ●OH is the dominant sink of secondary phenolic BrC in fog/cloud drops, while 3C* controls the lifetime of this light absorption in particle water.

We developed a method that uses aqueous S(IV) to quantitatively convert NO2 to NO2−, which allows both species to be quantified using the Griess method. As an example of the utility of the method, we quantified both photolysis channels of nitrate, with and without a scavenger for hydroxyl radical (·OH). The results show that without a scavenger, ·OH reacts with nitrite to form nitrogen dioxide, suppressing the apparent quantum yield of NO2− and enhancing that of NO2.

This study demonstrates the role of desorption energy governing the residence time of the gas species at the environmental interface. A parameterization is formulated that enables the prediction of desorption energy based on the molecular weight, polarizability, and oxygen-to-carbon ratio of the desorbing chemical species. Its application to gas–particle interactions is discussed.

The chemistry driving dimethyl sulfide (DMS) oxidation and subsequent sulfate particle formation in the atmosphere is poorly constrained. We oxidized two related compounds (dimethyl sulfoxide and dimethyl disulfide) in the laboratory under varied NOx conditions and measured the gas- and particle-phase products. These results demonstrate that both the OH addition and OH abstraction pathways for DMS oxidation contribute to particle formation via mechanisms that do not involve the SO2 intermediate.

In this study we examined the effect of atmospheric aging on sea spray aerosols (SSAs) to form ice and how newly formed secondary marine aerosols (SMAs) may freeze at cirrus temperatures (< −38 °C). Results show that SSAs freeze at different relative humidities (RHs) depending on the temperature and that the ice-nucleating ability of SSA was not hindered by atmospheric aging. SMAs are shown to freeze at high RHs and are likely inefficient at forming ice at cirrus temperatures.

We studied reactions of secondary ozonides (SOZs) with amines. SOZs formed from ozonolysis of β-caryophyllene and α-humulene are found to be reactive to ethylamine and methylamine.

Our findings indicate that interaction of SOZs with amines in the atmosphere is very complicated, which is potentially a hitherto unrecognized source of N-containing compound formation.

We measured concentrations of three photooxidants – the hydroxyl radical, triplet excited states of organic carbon, and singlet molecular oxygen – in fine particles collected over a year. Concentrations are highest in extracts of fresh biomass burning particles, largely because they have the highest particle concentrations and highest light absorption. When normalized by light absorption, rates of formation for each oxidant are generally similar for the four particle types we observed.

D5 is an emerging anthropogenic pollutant that is ubiquitous in indoor and urban environments, and the OH oxidation of D5 forms secondary organosiloxane aerosol (SOSiA). Application of a kinetic box model that uses a volatility basis set (VBS) showed that consideration of oxidative aging (aging-VBS) predicts SOSiA formation much better than using a standard-VBS model. Ageing-dependent parameterization is needed to accurately model SOSiA to assess the implications of siloxanes for air quality.

Dust is a major source of atmospheric aerosols. Its chemical composition is often assumed to be similar to the parent soil. However, this assumption has not been rigorously verified. Dust aerosols are mainly generated by wind erosion, which may have some chemical selectivity. Mn, Cd and Pb were found to be highly enriched in fine-dust (PM2.5) aerosols. In addition, estimation of heavy metal emissions from dust generation by air quality models may have errors without using proper dust profiles.

A major uncertainty in our understanding of clouds and climate is the sources and properties of the aerosol on which clouds grow. We found that aerosol containing organic matter from fast-growing marine phytoplankton was a source of ice-nucleating particles (INPs). INPs facilitate freezing of ice crystals at warmer temperatures than otherwise possible and therefore change cloud formation and properties. Our results show that ecosystem processes and the properties of sea spray aerosol are linked.

Therefore, the development of megacities should pay more attention to the health burden of vehicle emissions, coal combustion, and industrial processes. This study provides new insight into assessing the relationship between source apportionment and health risks and can provide valuable insight into air pollution strategies.

With important climate and air quality impacts, atmospheric multiphase chemistry involves gas interactions with aerosol particles and cloud droplets. We summarize the status of the field and discuss potential directions for future growth. We highlight the importance of a molecular-level understanding of the chemistry, along with atmospheric field studies and modeling, and emphasize the necessity for atmospheric multiphase chemists to interact widely with scientists from neighboring disciplines.

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.

Detailed chemical analysis of organic aerosols is necessary to better understand their effects on climate and health. Aerosol samples are often stored for days to months before analysis. We examined the effects of storage conditions (i.e., time, temperature, and aerosol storage on filters or as solvent extracts) on composition and found significant changes in the concentration of individual compounds, indicating that sample storage can strongly affect the detailed chemical particle composition.

Short summary
In the study, humic-like substances (HULIS) in smoke PM2.5 emitted from the combustion of biomass materials and fossil fuels are studied. The results indicate that both biomass burning and coal combustion are important primary sources of atmospheric HULIS. Moreover, the primary HULIS and atmospheric HULIS are similar in many properties, but some distinct features are also apparent. These results are helpful to understand the contribution and chemical nature of HULIS in combustion emissions.
