We performed chamber experiments to measure the composition of the gas-phase reaction products of nitrate-radical-initiated oxidation of four monoterpenes. The total organic yield, effective oxygen-to-carbon ratio, and dimer-to-monomer ratio were correlated with the observed particle formation for the monoterpene systems with some exceptions. The Δ-carene system produced the most particles, followed by β-pinene, with the α-pinene and α-thujene systems producing no particles.

Ambient forest air was oxidized by OH, O3, or NO3 inside an oxidation flow reactor, leading to formation of particulate matter from any gaseous precursors found in the air. Closure was achieved between the amount of particulate mass formed from O3 and NO3 oxidation and the amount predicted from speciated gaseous precursors, which was in contrast to previous results for OH oxidation (Palm et al., 2016). Elemental analysis of the particulate mass formed in the reactor is presented.

The lifetime of nitrogen oxides (NOx) is evaluated by analysis of field measurements from the southeastern United States. At warm temperatures in the daytime boundary layer, NOx interconverts rapidly with both PAN and alkyl and multifunctional nitrates (RONO2), and the relevant lifetime is the combined lifetime of these three classes. We find that the production of RONO2, followed by hydrolysis to produce nitric acid, is the dominant pathway for NOx removal in an isoprene dominated forest.

This paper reports atmospheric gas- and aerosol-phase field measurements from the southeastern United States in summer 2013 to demonstrate that the oxidation of biogenic volatile organic compounds by nitrate radical produces a substantial amount of secondary organic aerosol in this region. This process, driven largely by monoterpenes, results in a comparable aerosol nitrate production rate to inorganic nitrate formation by heterogeneous uptake of HNO3 onto dust particles.

We report ion chromatographic measurements of gas- and aerosol-phase inorganic species at the SOAS 2013 field study. Our particular focus is on inorganic nitrate aerosol formation via HNO3 uptake onto coarse-mode dust and sea salt particles, which we find to be the dominant source of episodic inorganic nitrate at this site, due to the high acidity of the particles preventing formation of NH4NO3. We calculate a production rate of inorganic nitrate aerosol.

It is of increasing importance to monitor nitrate pollution that can harm ecosystems. However, commonly used aerosol monitoring equipment cannot distinguish inorganic from organic forms of nitrate, which may have different consequences for the environment. We describe a method to differentiate types of nitrates that can be applied to ambient monitoring to improve understanding of its formation and impact.

Particulate matter (PM) is a harmful air pollutant that depends on the complex mixture of natural and anthropogenic emissions into the atmosphere. Thus, in different regions and seasons, the way that PM is formed and grows can differ. In this study, we use a combined statistical analysis of the chemical composition and particle size distribution to determine what drives particle formation and growth across seasons, using varying wind directions to elucidate the role of different sources.

The investigation of the night-time oxidation of the most abundant hydrocarbon, isoprene, in chamber experiments shows the importance of reaction pathways leading to epoxy products, which could enhance particle formation, that have so far not been accounted for. The chemical lifetime of organic nitrates from isoprene is long enough for the majority to be further oxidized the next day by daytime oxidants.

Isoprene is the biogenic volatile organic compound with the largest emissions rates. The nighttime reaction of isoprene with the NO3 radical has a large potential to contribute to SOA. We classified isoprene nitrates into generations and proposed formation pathways. Considering the potential functionalization of the isoprene nitrates we propose that mainly isoprene dimers contribute to SOA formation from the isoprene NO3 reactions with at least a 5 % mass yield.

This paper describes a new instrument (a thermal-dissociation–cavity ring-down spectrometer, TD-CRDS) for the measurement of key atmospheric gaseous and particle-phase molecules containing the nitrate functional group. Several operational considerations affecting the measurements are described, as well as several characterization experiments comparing the TD-CRDS measurements to analogous measurements from other instruments. Examples are given using a TD-CRDS for ambient and laboratory studies.

Secondary organic aerosol (SOA) is produced through a complex interaction of sunlight, volatile organic compounds emitted from trees, anthropogenic emissions, and atmospheric chemistry. We are able to successfully model the formation and diurnal evolution of SOA using a model that takes into consideration the surface and boundary layer dynamics (1–2 km from the surface) and photochemistry above the southeastern US with data collected during the SOAS campaign to constrain the model.

This paper uses measurements made during research aircraft flights through power plant smokestack emissions plumes as a natural laboratory in the field experiment. We investigated a specific source of airborne particulate matter from the combination of human-produced NOx pollutant emissions (the smokestack plumes) with isoprene emitted by naturally by trees in the southeastern United States. These field-based yields appear to be higher than those typically measured in chamber studies.

Thermodynamic modeling revealed that some but not all measurements of ammonium-to-sulfate ratios are consistent with theory. The measurement diversity likely explains the previously reported range of results regarding the suitability of thermodynamic modeling. Despite particles being predominantly phase separated, organic–inorganic interactions resulted in increased aerosol pH and partitioning towards the particle phase for highly oxygenated organic compounds compared to traditional methods.

Formic acid (HCOOH) is an abundant atmospheric acid that affects precipitation chemistry and acidity. HCOOH measurements over the USA are 2-3× larger than can be explained by known sources and sinks, revealing a key gap in current understanding. Observations indicate a large biogenic source plus chemical production across a range of precursors. Model simulations cannot capture the HCOOH diurnal amplitude or nocturnal profile, implying a deposition bias and possibly even larger missing source.

Submicron particle mass concentration in the Amazon during the wet season of 2008 was dominated by organic material. The PMF analysis finds a comparable importance of gas-phase (gas-to-particle condensation) and particle-phase (reactive uptake of isoprene oxidation products, especially of epoxydiols to acidic haze, fog, or cloud droplets) production of secondary organic material during the study period, together accounting for >70% of the organic-particle mass concentration.

We use modeled estimates of BVOCs from the years 1000 to 2000 to test the effect of anthropogenic BVOC emission changes on SOA formation, aerosol size distributions, and radiative effects using the GEOS-Chem-TOMAS model. Changes of >25% in the number of particles with diameters >80nm are predicted regionally due to extensive land-use changes, leading to increases in combined radiative effect of >0.5 Wm-2. This change in radiative forcing could be an overlooked anthropogenic effect on climate.

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. To explain this difference, we propose that as the complexity of the sample increases, the hydrophobic interfaces in the bulk compete with the air–water interface.

This work provides the first fundamental laboratory data to evaluate SOA (secondary organic aerosol) production from styrene and NO3 chemistry. Additionally, the formation mechanisms of aromatic organic nitrates (ONs) are reported, highlighting that previously identified nitroaromatics in ambient field campaigns can be aromatic ONs. Finally, the hydrolysis lifetimes observed for ONs generated from styrene and NO3 oxidation can serve as experimentally constrained parameters for modeling hydrolysis of aromatic ONs in general.

Hydrogen peroxide (HOOH) is an important oxidant that forms atmospheric sulfate. We demonstrate that the 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 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 future policy.

Halogenated polycyclic aromatic hydrocarbons (XPAHs) are emerging pollutants. Stability during atmospheric transformation processes is crucial for predicting their environmental fate and assessing the 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.

The initiation of autoxidation by ozonolysis was investigated on levitated linoleic acid droplets using electrodynamic balance–mass spectrometry. Exposing the droplets to ozone for one hour before switching the gas phase to air without ozone led to a shortening of the autoxidation initiation phase in comparison to experiments without ozone exposure. Results were compared to a bulk reaction model to investigate the synergistic effects of ozonolysis and autoxidation.

The assessment of chromium occurrence in particulate matter in cities: PM10, PM2.5, PM1 and PM0.25 during the calendar year was presented. The seasonality of both pseudototal chromium content and its valence speciation was examined. Seasonality of changes in Crtot and Cr(VI) concentrations was observed. Maximum in the winter season, most likely due to the greater share of fuel combustion sources. Regardless of the season, the risk levels for Radom residents were within the acceptable risk range.

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.

This article comprehensively investigates the aqueous-phase OH oxidation of benzothiazoles (BTs), common rubber additives found in urban air, through laboratory simulation experiments. BTs can rapidly degrade, leading to light absorption, high yields of sulfate, and the formation of highly oxidized and/or oligomerized organic compounds. The results reveal that aqueous-phase BTs can contribute to secondary aerosols, altering the chemical and optical properties of atmospheric particles.

We investigated the aqueous nitrate-mediated photooxidation of four green leaf volatiles (GLVs). The aqueous reaction medium conditions, dilute cloud/fog vs. concentrated aqueous aerosol conditions, governed the effects that pH, ionic strength, and sulfate have on the GLV degradation rates and aqSOA mass yields. Most notably, reactions initiated by sulfate photolysis have significant effects in aqueous aerosols, but not in cloud/fog droplets.

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.

Air pollution and climate change are influenced by tiny airborne particles called aerosols. This study explores how pollutants from urban sources, as m-xylene and naphthalene, form new particles in the atmosphere under different conditions. Using advanced techniques, we show how temperature and nitrogen oxides affect the formation and behaviour of these particles. Our findings will improve our understanding on secondary organic particle and air quality models.

High-latitude cities like Fairbanks, Alaska, experience severe wintertime pollution episodes. While conventional wisdom holds that oxidation is slow under these conditions, field measurements find oxidized products in particles. To explore this, we measured oxidants in aqueous extracts of winter particles from Fairbanks. We find high concentrations of oxidants during illumination, indicating that particle photochemistry can be significant even in high latitudes during winter.

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 the reactivity with ozone is likely impacted by aerosol phase state (e.g. aerosol viscosity).

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.

Photochemical reactions altered the properties of kerosene-operated jet engine burner exhaust emissions, which were studied in laboratory using an oxidation flow reactor. Particle mass increased 300-fold as particles and gases became more oxidized. Light absorption increased, but the total direct radiative forcing efficiency was estimated to shift from positive to negative. The results highlight the importance of considering secondary aerosol formation when assessing the impacts of aviation.

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.

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.

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 initial step of interfacial and multiphase chemical processes involves adsorption and desorption of gas species. 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.

Secondary organic aerosol (SOA) from gasoline vehicles can be a significant source of particulate matter in urban areas. Here the chemical composition of secondary volatile organic compounds and SOA produced by photo-oxidation of Euro 5 gasoline vehicle emissions was studied. The volatility of the SOA formed was calculated. Except for the temperature and the concentration of the aerosol, additional parameters may play a role in the gas-to-particle partitioning.

Specific tracer compounds identified previously in controlled test burnings of different waste types in the laboratory were detected and quantified in ambient PM10 samples collected in five Hungarian and four Romanian settlements. Back-of-the-envelope calculations based on the relative emission factors of individual tracers suggested that the contribution of solid waste burning particulate emissions to ambient PM10 mass concentrations may be as high as a few percent.

PM2.5 are air pollutants threatening health globally, but they are a mixture of chemical compositions from many sources and result in unequal toxicity. Which composition from which source of PM2.5 as the most hazardous object is a question hindering effective pollution control policy-making. With chemical and toxicity experiments, we found automobile exhaust and coal combustion to be priority emissions with higher toxic compositions for precise air pollution control, ensuring public health.

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.

This article reports the results of the kinetic measurements for the aqueous oxidation of the 29 aliphatic alcohols by hydroxyl radical (OH) at different temperatures. The data acquired and the literature data were used to optimize a model for predicting the aqueous OH reactivity of alcohols and carboxylic acids and to estimate the atmospheric lifetimes of five terpenoic alcohols. The kinetic data provided new insights into the mechanism of aqueous oxidation of aliphatic molecules by the OH.

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. Products from SOZs with various conformations reacting with the same amine had different functional groups. 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.

The effect of dust emitted from desertic surfaces upon climate and ecosystems depends on size and mineralogy, but data from soil mineral atlases of desert soils are scarce. We performed particle-size distribution, mineralogy, and Fe speciation in southern Morocco. Results show coarser particles with high quartz proportion are near the elevated areas, while in depressed areas, sizes are finer, and proportions of clays and nano-Fe oxides are higher. This difference is important for dust modelling.

Large uncertainties remain in understanding secondary organic aerosol (SOA) formation from toluene oxidation. In this study, speciation measurements in gaseous and particulate phases were carried out, providing partitioning and volatility data on individual toluene SOA components at different temperatures. A new detailed oxidation mechanism was developed to improve modeled speciation, and effects of different processes involved in gas–particle partitioning at the molecular scale are explored.

Short summary
The addition of NO2 to atmospheric particle formation simulations based on ozone reactions with tree-emitted monoterpenes results in changing particle composition and mass yields, with effects that vary across the range of studied monoterpenes. For alpha-pinene, a dominantly emitted terpene in the United States, NO2 addition suppresses particle formation, while for others, particle yields remain high.
