The Wufeng to Longmaxi (WF-LMX) Formations are the most important shale gas play in China. Here, we present a feasible approach using nanoindentation to characterize the mechanical properties of the WF-LMX Formations. Mechanical properties varied synchronously with mineral and organic content across the vertical drilling profile, reflecting changes in lithology and sedimentary facies. The effect of shale constituents on micromechanics is essentially controlled by the sedimentary environment.

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.

The formation pathways of nitrogen-containing compounds (NOCs) in the atmosphere remain unclear. We investigated the composition of aerosols and fog water by state-of-the-art mass spectrometry and compared the formation pathways of NOCs. We found that NOCs in aerosols were mainly formed through nitration reaction, while ammonia addition played a more important role in fog water. The results deepen our understanding of the processes of organic particulate pollution.

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.

The results show that 14C elemental carbon (EC) was not only related to the isolation method but also to the types and proportions of the biomass sources in the sample. The hydropyrolysis (Hypy) method, which can be used to isolate a highly stable portion of ECHypy and avoid charring, is a more effective and stable approach for the matrix-independent 14C quantification of EC in aerosols, and the 13C–ECHypy and non-fossil ECHypy values of SRM1649b were –24.9 ‰ and 11 %, respectively.

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.

This work comprehensively investigated the fluorescence data of light-absorbing organic compounds, water-soluble organic matter in different types of aerosol samples, soil dust, and fulvic and humic acids using an excitation–emission matrix (EEM) method and parallel factor modeling. The results revealed which light-absorbing species can be detected by EEM and also provided important information for identifying the chemical composition and possible sources of these species in atmospheric samples.

In this study, PM2.5 samples were obtained during a winter haze event in Guangzhou, China, and light absorption and molecular composition of humic-like substances (HULIS) were investigated by UV–Vis spectrophotometry and ultrahigh-resolution mass spectrometry. The findings obtained present some differences from the results reported in other regions of China and significantly enhanced our understanding of HULIS evolution during haze bloom-decay processes in the subtropic region of southern China.

We show that in-cloud aqueous processing facilitates the formation of brown carbon (BrC), based on the simultaneous measurements of the light-absorption properties of the cloud residuals, cloud interstitial, and cloud-free particles. While extensive laboratory evidence indicated the formation of BrC in aqueous phase, our study represents the first attempt to show the possibility in real clouds, which would have potential implications in the atmospheric evolution and radiation forcing of BrC.

We sampled cloud water at a remote mountain site and investigated the molecular characteristics. CHON and CHO are dominant in cloud water. No statistical difference in the oxidation state is observed between cloud water and interstitial PM2.5. Most of the formulas are aliphatic and olefinic species. CHON, with aromatic structures and organosulfates, are abundant, especially in nighttime samples. The in-cloud and multi-phase dark reactions likely contribute significantly.

We build a novel system that utilizes an aerodynamic aerosol classifier (AAC) combined with a single-particle aerosol mass spectrometry (SPAMS) to simultaneously characterize the volume equivalent diameter (Dve), chemical compositions, and effective density (ρe) of individual particles in real time. A test of the AAC-SPAMS with both spherical and aspherical particles shows that the deviations between the measured and theoretical values are less than 6 %.

We carried out a 1-year PM concurrent observation at 12 sites across six regions of China, and size-segregated PAHs were measured. We found both PAHs and BaPeq were concentrated in PM1.1, and northern China had higher PAHs' pollution and inhalation cancer risk than southern China. Nationwide increases in both PAH levels and inhalation cancer risk occurred in winter. We suggest reducing coal and biofuel consumption in the residential sector is an important option to mitigate PAHs' health risks.

Based on the analysis of the morphology and mixing structure of the activated and unactivated particles, our results emphasize the role of in-cloud processes in the chemistry and microphysical properties of individual activated particles. Given that organic coatings may determine the particle hygroscopicity and heterogeneous chemical reactivity, the increase of OM-shelled particles upon in-cloud processes should have considerable implications for their evolution and climate impact.

The composition and light-induced evolution of a water-soluble organic carbon mixture from fresh biomass burning aerosols was investigated with direct infusion electrospray ionisation high-resolution mass spectrometry (HRMS) and liquid chromatography coupled with HRMS. Our findings indicate that the water-soluble organic fraction of combustion-derived aerosols has the potential to form more oxidised organic matter, contributing to the highly oxygenated nature of atmospheric organic aerosols.

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.

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.

The effects of the chemical composition and size of sea-salt-containing particles on their cloud condensation nuclei activity are incompletely understood. Our results showed that submicron sea-salt-containing particles can enrich in small cloud droplets, likely due to change in the chemical composition, while supermicron sea-salt-containing particles tended in the large cloud droplets less affected by chemical composition. This difference might further influence their atmospheric residence time.

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.

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.

Understanding the surface composition of aerosols is crucial for advancing climate models. We investigated the interface of single-component and mixed aqueous solutions of atmospherically relevant carboxylic acid and alkyl-ammonium ions using liquid-jet photoelectron spectroscopy. An exponential increase in surface propensity as a function of chain length was found for the single species, and cooperative effects in the mixtures cause a further drastic increase in surface solute concentration.

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.

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.

Recent research has established the contribution of 1,3-butadiene (13BD) to organic aerosol formation with negative implications for urban air quality. Health effect studies have focused on whole particulate matter, but compounds responsible for adverse health effects remain uncertain. This study provides the effect of relative humidity and seed aerosol acidity on the chemical composition of aerosol formed from 13BD photooxidation.

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 provides the first fundamental laboratory data to evaluate SOA production from styrene+NO3 chemistry. Additionally, the formation mechanisms of aromatic ONs are reported for the first time, highlighting that previously identified nitroaromatics in ambient field campaigns can be aromatic ONs. Finally, the hydrolysis lifetime observed for ONs generated from styrene+NO3 oxidation can serve as experimentally constrained parameter for modeling hydrolysis of aromatic ONs in general.

We followed nano-structural changes in mixtures found in urban organic aerosol emissions (oleic acid, sodium oleate and fructose) during humidity change and ozone exposure. We demonstrate that self-assembly of fatty acid nanostructures can impact water uptake and chemical reactivity, affecting atmospheric lifetimes, urban air quality (preventing harmful emissions from degradation and enabling their long-range transport) and climate (affecting cloud formation), with implications for human health.

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.

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.

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 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.

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.

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.

The unique formulas of coal combustion aerosols were characterized by higher unsaturated compounds, and such information could be used for source appointment.

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.

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.

This paper reports source profiles and emission factors for PM2.5 species and acidic/alkali gases from laboratory combustion of 10 waste categories (including plastics and biomass) that represent open burning in South Africa. Results will be useful for health and climate impact assessments, speciated emission inventories, source-oriented dispersion models, and receptor-based source apportionment.

We conducted burning experiments to simulate various types of solid fuel combustion, including residential burning, wildfires, agricultural burning, cow dung, and plastic bag burning. The chemical composition of the particles was characterized using mass spectrometers, and new potential markers for different fuels were identified using statistical analysis. This work improves our understanding of emissions from solid fuel burning and offers support for refined source apportionment.

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.

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.

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.

Aerosols and films are found indoors and outdoors. Our study measures and models reactions of a cooking aerosol proxy with the atmospheric oxidant ozone relying on a low-cost but sensitive technique based on mass changes and film rigidity. We found that film morphology changed and film rigidity increased with evidence of surface crust formation during ozone exposure. Our modelling results demonstrate clear potential to take this robust method to the field for reaction monitoring.

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.

Although the main source contribution of pollution is secondary inorganic aerosols in Nanjing, health risks mainly come from industry sources and vehicle emissions. 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.

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.

Short summary
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.
