The formation mechanisms of secondary organic aerosol and brown carbon from small α-carbonyls are still unclear. Thus, the mechanisms and kinetics of aqueous-phase reactions of glyoxal were investigated using quantum chemical and kinetic rate calculations. Several essential isomeric processes were identified, including protonation to yield diol/tetrol and carbenium ions as well as nucleophilic addition of carbenium ions to diol/tetrol and free methylamine/ammonia.

Tropical cyclones (TCs) can cause catastrophic damages to coastal regions. We used a numerical model that explicitly simulates aerosol-cloud interaction and atmosphere-ocean coupling. We show that aerosols and ocean coupling work together to make the TC storm bigger but weaker. Moreover, TCs in polluted air have more rainfall and higher sea levels, leading to severer storm surges and flooding. Our research highlights the roles of aerosols and ocean coupling feedbacks in the TC hazard assessment.

Severe regional haze events, which are characterized by exceedingly high levels of fine particulate matter (PM), occur frequently in many developing countries (such as China and India), with profound implications for human health, weather, and climate. Our work establishes a synthetic view for the dominant regional features during severe haze events, unraveling rapid in situ PM production and inefficient transport, both of which are amplified by atmospheric stagnation.

Severe haze formation in Beijing during wintertime is attributed to explosive secondary aerosol formation including particle nucleation and subsequent particle growth. Organic matter is responsible for producing nucleation mode particles, while secondary organic and inorganic components jointly contribute to the high aerosol mass during haze episodes. High levels of gaseous precursors and stagnant air mass are responsible for fast secondary aerosol formation.

We have investigated the molecular interactions between succinic acid and sulfuric acid–base clusters in the presence of hydration, including ammonia and dimethylamine. Our results indicate that the multicomponent nucleation involving organic acids, sulfuric acid, and base species promotes new particle formation in the atmosphere, particularly under polluted conditions.

Several studies using thermodynamic models estimated pH and sulfate formation rate during pollution periods in China are highly conflicting. Here we show distinct sulfate formation for organic seed particles from that of (NH4)2SO4 seeds, when the particles are exposed to SO2, NO2, and NH3 at high RH. Our results reveal that the pH value of ambient organics-dominated aerosols is sufficiently high to promote efficient SO2 oxidation by NO2 with NH3 neutralization under polluted conditions in China.

The mixing of dust and anthropogenic pollution over East Asia plays a significant yet poorly quantified role in aerosol radiative effects. We have found that radiative absorption of the East Asian aerosol mixtures are significantly enhanced. Our results show that the interaction between dust and anthropogenic pollution not only represents a viable aerosol formation pathway but also results in unfavorable dispersion conditions, both exacerbating the regional air pollution in East Asia.

Rapid growth of BC particles was observed in Beijing using a new outdoor chamber, with an average growth rate of 26 ± 11 nm h−1. Secondary organic aerosol (SOA) accounted for more than 90 % of the coating mass. The hygroscopic growth factor of BC particles increased to 1.06–1.08 upon ageing. The κ (kappa) values for BC particles were calculated as only 0.035, indicating that initial photochemical ageing of BC particles does not appreciably alter the particle hygroscopicity in Beijing.

This study reports the distinct effects of street canyons on new particle formation (NPF) under warm or cold ambient temperature conditions because of on-road vehicle emissions; i.e., stronger condensation sinks are responsible for the reduced NPF in the springtime, but efficient nucleation and partitioning of gaseous species contribute to the enhanced NPF in the wintertime. The oxidization of biogenic organics is suggested to play an important role in growing new particles.

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.

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.

Open burning of household and municipal solid waste is a common practice in developing countries and is a significant source of air pollution. However, few studies have measured emissions from open burning of waste. This study determined gas and particulate emissions from open burning of 10 types of household solid-waste materials. These results can improve emission inventories, air quality management, and assessment of the health and climate effects of open burning of household waste.

Pyrolysis is the thermal decomposition of fuels like wood which occurs during combustion or as an isolated process. During combustion, some pyrolysis products are emitted directly, while others are oxidized in the combustion process. This work describes the chemical composition of particle-phase pyrolysis products in order to investigate both the uncombusted emissions from wildfires and the fuel that participates in combustion.

Although photooxidants are important in airborne particles, little is known of their concentrations. By measuring oxidants in a series of particle dilutions, we predict their concentrations in aerosol liquid water (ALW). We find •OH concentrations in ALW are on the order of 10−15 M, similar to their cloud/fog values, while oxidizing triplet excited states and singlet molecular oxygen have ALW values of ca. 10−13 M and 10−12 M, respectively, roughly 10–100 times higher than in cloud/fog drops.

Based on ultra-high-resolution mass spectrometry analysis, we found that β-pinene oxidation-derived highly oxygenated organic molecules (HOMs) exhibit higher yield at high ozone concentration, while limonene oxidation-derived HOMs exhibit higher yield at moderate ozone concentration. The distinct molecular response of HOMs and low-volatile species in different biogenic secondary organic aerosols to ozone concentrations provides a new clue for more accurate air quality prediction and management.

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.

Organic aerosols directly emitted from wood and pellet stove combustion are found to chemically transform (approximately 15 %–35 % by mass) under daytime aging conditions simulated in an environmental chamber. A new marker for lignin-like compounds is found to degrade at a different rate than previously identified biomass burning markers and can potentially provide indication of aging time in ambient samples.

Oxidation of limonene, an element emitted by trees and chemical products, by OH, a daytime oxidant, forms many highly oxygenated organic molecules (HOMs), including C10-20 compounds. HOMs play an important role in new particle formation and growth. HOM formation can be explained by the chemistry of peroxy radicals. We found that a minor branching ratio initial pathway plays an unexpected, significant role. Considering this pathway enables accurate simulations of HOMs and other concentrations.

Environmentally persistent free radicals (EPFRs) are an emerging pollutant found in soot particles. Understanding how these change as they move through the atmosphere is important to human health. Here, soot was generated in the laboratory and exposed to simulated sunlight. The concentrations and characteristics of EPFRs in the soot were measured and found to be unchanged. However, it was also found that the ability of soot to form hydroxyl radicals was stronger for fresh soot.

We studied how aqueous-phase secondary organic aerosol (aqSOA) form and evolve from a phenolic carbonyl commonly present in biomass burning smoke. The composition and optical properties of the aqSOA are significantly affected by photochemical reactions and are dependent on the oxidants' concentration and identity in water. During photoaging, the aqSOA initially becomes darker, but prolonged aging leads to the formation of volatile products, resulting in significant mass loss and photobleaching.

In this study, we present an intercomparison of four different techniques for measuring the chemical composition of nanoparticles. The intercomparison was performed based on the observed chemical composition, calculated volatility, and analysis of the thermograms. We found that the methods generally agree on the most important compounds that are found in the nanoparticles. However, they do see different parts of the organic spectrum. We suggest potential explanations for these differences.

Incense burning is a common practice in Asia, posing great 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 for the first time. IVOCs are crucial organics accounting for 19.2 % of the total EFs and 40.0 % of the SOA estimation, highlighting the importance of incorporating IVOCs into SOA models.

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.

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.

Photosensitizers play an important role in the photochemistry of atmospheric aerosols. Our study provides evidence that mesoscopic glycine clusters forming in aqueous droplets act as unconventional photosensitizers in the visible light spectrum. We observed the influence of these photoactive molecular aggregates in single optically trapped aqueous droplets. Such mesoscopic photosensitizers might be more important for aerosol photochemistry than previously anticipated.

VCPs are a class of chemicals widely used in industrial and consumer products (e.g., coatings, adhesives, inks, personal care products) and are an important component of total VOCs in urban atmospheres. This study provides SOA yields and detailed chemical analysis of the gas- and aerosol-phase products of the photooxidation of one of these VCPs, benzyl alcohol. These results will allow better links between characterized sources and their resulting criteria for pollutant formation.

Based on the combined measurements of gas- and particle-phase highly oxygenated organic molecules (HOMs) from α-pinene ozonolysis, enhancement of dimers in particles was observed. We conducted experiments wherein the dimer to monomer (D / M) ratios of HOMs in the gas phase were modified (adding CO / NO) to investigate the effects of the corresponding D / M ratios in the particles. These results are important for a better understanding of secondary organic aerosol formation in the atmosphere.

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.

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 (PM2.5) dust aerosols. In addition, estimation of heavy metal emission from dust generation by air quality models may have errors without using proper dust profiles.

The promotion of soluble saccharides on sea spray aerosol (SSA) generation and the changes in particle morphology were observed. On the contrary, the coexistence of surface insoluble fatty acid film and soluble saccharides significantly inhibited the production of SSA. This is the first demonstration that hydrogen bonding mediated by surface-insoluble fatty acids contributes to saccharide transfer in seawater, providing a new mechanism for saccharide enrichment in SSA.

A major uncertainty in our understanding of clouds and climate are the sources and properties of the aerosol on which clouds grow. We found that aerosol containing organic matter from fast growing marine phytoplankton were 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 ecosystem processes and the properties of sea spray aerosol are linked.

The diurnal pattern in biogenic secondary organic aerosol (SOA) formation is simulated by using the UNIPAR model, which predicts SOA growth via multiphase reactions of hydrocarbons under varying NOx levels, aerosol acidity, humidity, and temperature. The simulation suggests that nighttime SOA formation, even in urban environments, where anthropogenic emission is high, is dominated by products from ozonolysis and NO3-initiated oxidation of biogenic hydrocarbons.

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.

Interaction between NOx and biogenic emissions can be important in suburban areas. Our study showed that the addition of NOx during α-pinene SOA formation produced considerable amounts of organic nitrates and affected the composition of non-nitrated organic compounds. The compositional difference consequently altered the primary type of aqueous-phase processes during the isothermal particle evaporation.

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.

Deep interrogation of water-soluble organic carbon (WSOC) in aerosols is critical and challenging considering its involvement in many key aerosol-associated chemical reactions.

We found that the pH- and particle-size-dependent behaviors could be used to reveal the structures, sources, and aging of aerosol WSOC.

The addition of a low-yield precursor to the reactive mixture of aVOC and bVOC can increase or decrease the SOA volatility that is system-dependent. Therefore, the SOA volatility of the mixtures cannot always be predicted based on the additivity. In complex mixtures the formation of lower-volatility products likely outweighs the formation of products with higher volatility. The unique products of each mixture contribute significantly to the signal, suggesting interactions can be important.

In this study, the influence of HCHO on renoxification on nitrate-doped TiO2 particles is investigated by using an experimental chamber. Mass NOx release is suggested to follow the NO−3-NO3·-HNO3-NOx pathway, with HCHO involved in the transformation of NO3· to HNO3 through hydrogen abstraction. Our proposed reaction mechanism by which HCHO promotes photocatalytic renoxification is helpful for deeply understanding the atmospheric photochemical processes and nitrogen cycling.

The oxidation of limonene, a common volatile emitted by trees and chemical products, by NO3, a nighttime oxidant, forms many highly oxygenated organic molecules (HOM), including C10-30 compounds. Most of the HOM are second-generation organic nitrates, in which carbonyl-substituted C10 nitrates accounted for a major fraction. Their formation can be explained by chemistry of peroxy radicals. HOM, especially low-volatile ones, play an important role in nighttime new particle formation and growth.

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.

Short summary
Here we elucidate the production of COOs and their roles in SOA and brown carbon formation from m-xylene oxidation by simultaneously monitoring the evolution of gas-phase products and aerosol properties in an environmental chamber. A kinetic framework is developed to predict SOA production from the concentrations and uptake coefficients for COOs. This functionality-based approach reproduces SOA formation from m-xylene oxidation well and is applicable to VOC oxidation for other species.
Here we elucidate the production of COOs and their roles in SOA and brown carbon formation from...
