Solvents represent an important source of pollution from the chemical industry. New "green" solvents aim to replace toxic solvents with new molecules made from renewable sources and designed to be less harmful. Whilst these new molecules are selected according to toxicity and other characteristics, no consideration has yet been included on air quality. Studying the solvent breakdown in air, we found that TMO has a lower impact on air quality than traditional solvents with similar properties.

OH and HO2 are key reactive intermediates in the Earth's atmosphere. Accurate measurements in either the field or simulation chambers provide a good test for chemical mechanisms. Fluorescence techniques have the appropriate sensitivity for detection but require calibration. This paper compares different methods of calibration and specifically how calibration factors vary across a temperature range relevant to atmospheric and chamber determinations.

This work explores the kinetics and reactivity of epoxides towards the OH radical using two different simulation chambers. Estimation of the rate coefficients has also been made using different structure–activity relationship (SAR) approaches. The results indicate a direct influence of the structural and geometric properties of the epoxides not considered in SAR estimations, influencing the reactivity of these compounds. The outcomes of this work are in very good agreement with previous studies.

Within this work we determined the rate coefficients and products of the reaction of unsaturated ketones with OH radicals in an effort to complete the gaps in the knowledge needed for modelling chemistry in the atmosphere. Both substances are potentially emitted by biomass burning, industrial activities or formed in the troposphere by oxidation of terpenes. As products we identified aldehydes and ketones which in turn are known to be responsible for the transportation of NOx species.

Environmental chamber studies were performed to evaluate atmospheric degradation initiated by OH radicals for two unsaturated methoxy ketones. The main gas-phase oxidation products identified and quantified from these reactions are carbonyls and long-lived nitrogen-containing compounds such as peroxyacetyl nitrate and peroxypropionyl nitrate. The kinetic rate constants and atmospheric lifetimes were estimated, degradation mechanisms were developed, and atmospheric implications were assessed.

In north-eastern Romania, enhancement in emission sources, changes in the mixed layer depth, and specific meteorological conditions were identified as critical factors controlling the seasonal variation in particulate ionic species. Particulate NH4+ and NO3− ions were assigned as critical parameters controlling aerosol chemistry. Long-range transport phenomena play an important role. Exploring aerosols' chemical composition and chemical processes still involves many challenges.

∆3-carene is abundantly emitted from vegetation, but its atmospheric oxidation chemistry has received limited attention. We explored highly oxygenated organic molecule (HOM) formation from ∆3-carene ozonolysis in chambers and investigated the impact of temperature and relative humidity on HOM formation. Our findings provide new insights into ∆3-carene oxidation pathways and their potential to impact atmospheric aerosols.

This paper outlines a unique scientific strategy for studying the reactivity of atmospherically relevant norpinonic acid (NA). The publication offers a new toolbox, illustrating NA's fragmentation and pattern of kinetic degradation leading to the formation of new small molecules. Furthermore, the research strategy presented here demonstrates how a mass spectrometer can function as a gas-phase reactor and the quantum chemistry method can serve as a reaction model builder.

The formation and evolution mechanisms of aromatics-derived highly oxygenated organic molecules (HOMs) are essential to understand the formation of secondary organic aerosol pollution. Our conclusion highlights an underappreciated formation pathway of aromatics-derived HOMs and elucidates detailed formation mechanisms of certain HOMs, which advances our understanding of HOMs and potentially explains the existing gap between model prediction and ambient measurement of the HOMs' concentrations.

Highly oxygenated organic molecules are important contributors to secondary organic aerosol. Their yield depends on detailed atmospheric chemical composition. One important parameter is the ratio of hydroperoxy radicals to organic peroxy radicals (HO2/RO2), and we show that higher HO2/RO2 ratios lower the secondary organic aerosol yield. This is of importance as laboratory studies are often biased towards organic peroxy radicals.

Ozone is deposited from the lower atmosphere to the surface of the ocean; however, the chemical reactions which drive this deposition are currently not well understood. Of particular importance is the reaction between ozone and iodide, and this work measures the kinetics of this reaction and its temperature dependence, which we find to be negligible. We then investigate the subsequent emissions of iodine-containing species from the surface ocean, which can further impact ozone.

Short summary
Due to the intrinsic connection between the formation pathways of O3 and HOMs, the ratio of HOM dimers or non-nitrate monomers to HOM organic nitrates could be used to determine O3 formation regimes. Owing to the fast formation and short lifetimes of HOMs, HOM-based indicating ratios can describe O3 formation in real time. Despite the success of our approach in this simple laboratory system, applicability to the much more complex atmosphere remains to be determined.

This study investigates the role of the important atmospheric reactive intermediates in the formation of dimers and aerosol in monoterpene ozonolysis at different temperatures. Through conducting a series of chamber experiments and utilizing chemical kinetic and aerosol dynamic models, the SOA formation processes are better described, especially for colder regions. The results can be used to improve the chemical mechanism modeling of monoterpenes and SOA parameterization in transport models.

The relative rate constants of OH radicals with C3-C11 alkanes under different bath gases (N2, Air, O2) were obtained, and multiple comparisons were made with previous literature and estimated values, expanding the existing database. The measured relative rate constants of air gases were found to be highly consistent with values obtained in N2, suggesting that the rate constants obtained in this experiment can reasonably represent the rate constants in the actual atmosphere.

In this work, we focus on the atmospheric chemistry and consequences for air quality of 2-methylpentanal (2MP), which is widely used as a flavoring ingredient and as an intermediate in the synthesis of dyes, resins, and pharmaceuticals. Measurements are presented on how fast 2MP is degraded by sunlight and oxidants like hydroxyl (OH) radicals and chlorine (Cl) atoms and what products are generated. We conclude that 2MP will be degraded in a few hours, affecting local air quality.

We look at the atmospheric chemistry of a volatile chemical product (VCP), benzyl alcohol. Benzyl alcohol and other VCPs may play a significant role in the formation of urban smog. By better understanding the chemistry of VCPs like benzyl alcohol, we may better understand observed data and how VCPs affect air quality. We identify products formed from benzyl alcohol chemistry and use this chemistry to understand how benzyl alcohol forms a key component of smog, secondary organic aerosol.

We developed a new method to generate nitrate radicals (NO3) for atmospheric chemistry applications that works by irradiating mixtures containing ceric ammonium nitrate with a UV light at room temperature. It has several advantages over traditional NO3 sources. We characterized its performance over a range of mixture and reactor conditions as well as other irradiation products. Proof of concept was demonstrated by generating and characterizing oxidation products of the β-pinene + NO3 reaction.

Acylperoxy radicals (RO2) are key intermediates in the atmospheric oxidation of organic compounds, yet our knowledge of their identities and chemistry remains poor. Using direct measurements and kinetic modeling, we identify the composition and formation pathways of acyl RO2 and quantify their contribution to highly oxygenated organic molecules during α-pinene ozonolysis, which will help to understand oxidation chemistry of monoterpenes and sources of low-volatility organics in the atmosphere.

In this study, the oxidations of sabinene by OH radicals and ozone were investigated with an atmospheric simulation chamber. Reaction rate coefficients of the OH-oxidation reaction at temperatures between 284 to 340 K were determined for the first time in the laboratory by measuring the OH reactivity. Product yields determined in chamber experiments had good agreement with literature values, but discrepancies were found between experimental yields and expected yields from oxidation mechanisms.

The trace gas carbonyl sulfide (OCS) transports sulfur from the troposphere to the stratosphere, where sulfate aerosols are formed that influence climate and stratospheric chemistry. An uncertain OCS source in the troposphere is chemical production form dimethyl sulfide (DMS), a gas released in large quantities from the oceans. We carried out experiments in a large atmospheric simulation chamber to further elucidate the chemical mechanism of OCS production from DMS.

This work illustrates how a common volatile hydrocarbon, hexanal, has the potential to undergo atmospheric autoxidation that leads to prompt formation of condensable material that subsequently contributes to aerosol formation, deteriorating the air quality of urban atmospheres. We used the combined state-of-the-art quantum chemical modeling and experimental flow reactor experiments under atmospheric conditions to resolve the autoxidation mechanism of hexanal initiated by a common oxidant.

By employing an improved net photochemical ozone production rate (NPOPR) detection system based on the dual-channel reaction chamber technique, we measured the net photochemical ozone production rate in the Pearl River Delta in China. The photochemical ozone formation mechanisms in the reaction and reference chambers were investigated using the observation-data-constrained box model, which helped us to validate the NPOPR detection system and understand photochemical ozone formation mechanism.

These findings provide a detailed characterization of the composition of the atmosphere downwind of wildfires. In turn, this will help to explore the effects of these changing emissions on downwind populations and will also directly inform atmospheric and climate models.

Solvents are chemical compounds with countless uses in the chemical industry, and they also represent one of the main sources of pollution in the chemical sector. Scientists are trying to develop new
greensafer solvents which present favourable advantages when compared to traditional solvents. Since the assessment of these green solvents often lacks air quality considerations, this study aims to understand the behaviour of these compounds, investigating their reactivity in the troposphere.

We observed a surprisingly similar set of oxidation product chemical formulas from limonene and α-pinene, including oligomers, formed under cool-flame (present experiments) and simulated atmospheric oxidation (literature). Data analysis indicated that a subset of chemical formulas is common to all experiments independently of experimental conditions. Also, this study indicates that many detected chemical formulas can be ascribed to an autooxidation reaction.

We discuss and show the viability of a method where multiple isotopically labelled precursors are used for probing the formation pathways of highly oxygenated organic molecules (HOMs) from the oxidation of the monoterpene a-pinene. HOMs are very important for secondary organic aerosol (SOA) formation in forested regions, and monoterpenes are the single largest source of SOA globally. The fast reactions forming HOMs have thus far remained elusive despite considerable efforts over the last decade.

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.

The trace gas peroxypropionyl nitrate (PPN) is generated in photochemical smog, phytotoxic, a strong eye irritant, and possibly mutagenic. Here, its solubility and reactivity in water and in octanol were investigated using a bubble flow apparatus, yielding its Henry's law constant and octanol–water partition coefficient (Kow). The results allow the fate of PPN to be more accurately constrained in atmospheric chemical transport models, including its uptake on clouds, organic aerosol, and leaves.

The atmospheric oxidation of dimethyl sulfide (DMS) is a major natural source of sulfate particles in the atmosphere. However, its mechanism is poorly constrained. In our work, laboratory measurements and mechanistic modeling were conducted to comprehensively investigate DMS oxidation products and key reaction rates. We find that the peroxy radical (RO2) has a controlling effect on product distribution and aerosol yield, with the isomerization of RO2 leading to the suppression of aerosol yield.

Solvents represent an important source of pollution from the chemical industry. New "green" solvents aim to replace toxic solvents with new molecules made from renewable sources and designed to be less harmful. Whilst these new molecules are selected according to toxicity and other characteristics, no consideration has yet been included on air quality. Studying the solvent breakdown in air, we found that TMO has a lower impact on air quality than traditional solvents with similar properties.

Emissions from four typical Chinese domestic cooking and fried chicken using four kinds of oils were investigated to illustrate the impact of cooking style and oil. Of the estimated SOA, 10.2 %–32.0 % could be explained by S/IVOC oxidation. Multiway principal component analysis (MPCA) emphasizes the importance of the unsaturated fatty acid-alkadienal volatile product mechanism (oil autoxidation) accelerated by the cooking and heating procedure.

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.

This study investigates the radical chemical budget during the limonene oxidation at different atmospheric-relevant NO concentrations in chamber experiments under atmospheric conditions. It is found that the model–measurement discrepancies of HO2 and RO2 are very large at low NO concentrations that are typical for forested environments.

This work explores the kinetics and reactivity of epoxides towards the OH radical using two different simulation chambers. Estimation of the rate coefficients has also been made using different structure–activity relationship (SAR) approaches. The results indicate a direct influence of the structural and geometric properties of the epoxides not considered in SAR estimations, influencing the reactivity of these compounds. The outcomes of this work are in very good agreement with previous studies.

The reaction between OH and SO2 is a termolecular process that in the atmosphere results in the formation of H2SO4 and thus aerosols. We present the first temperature- and pressure-dependent measurements of the rate coefficients in N2. This is also the first study to examine the effects of water vapour on the kinetics of this reaction. Our results indicate the rate coefficient is larger than that recommended by evaluation panels, with deviations of up to 30 % in some parts of the atmosphere.

Heterogeneous oxidation of SO2 is suggested to be one of the most important pathways for sulfate formation during extreme haze events in China, yet the exact mechanism remains highly uncertain. Our study reveals that ubiquitous compounds at the sea surface PAHS and DMSO, when exposed to SO2 under simulated sunlight irradiation, generate abundant organic sulfur compounds, providing implications for air-sea interaction and secondary organic aerosols formation processes.

Landscape fires are a major source of greenhouse gases and aerosols, particularly in sub-tropical savannas. Stable carbon isotopes in emissions can be used to trace the contribution of C3 plants (e.g. trees or shrubs) and C4 plants (e.g. savanna grasses) to greenhouse gases and aerosols if the process is well understood. This helps us to link individual vegetation types to emissions, identify biomass burning emissions in the atmosphere, and improve the reconstruction of historic fire regimes.

The diurnal atmospheric degradation of 2-methylbutanal, 2 MB, emitted by sources like vegetation or the poultry industry is evaluated in this work. Sunlight and oxidants like hydroxyl (OH) radicals and chlorine (Cl) atoms initiate this degradation. Measurements of how fast 2 MB is degraded and what products are generated are presented. The lifetime of 2 MB is around 1 h at noon, when the OH reaction dominates. Thus, 2 MB will not be transported far, affecting only local air quality.

Every spring in the Arctic, a series of photochemical events occur over the ice-covered ocean, known as bromine explosion events, ozone depletion events, and mercury depletion events.

The success provides a new platform with new opportunities to uncover fundamental mechanisms of these Arctic springtime phenomena and how they may change in a changing climate.

Wildfires are increasing in extent and severity, driven by climate change. Such fires emit large amounts of volatile organic compounds (VOCs) to the atmosphere. Many of these, such as the furans studied here, are very reactive and are rapidly converted to other VOCs, which are expected to have negative health effects and to further impact the climate. Here, we establish the importance of the nitrate radical for removing these compounds both during the night and during the day.

Understanding the chemistry of biomass burning plumes is of global interest. Within this work we investigated the OH radical reaction of 3-penten-2-one, which has been identified in biomass burning emissions. We observed the primary formation of peroxyacetyl nitrate (PAN), a key NOx reservoir species. Besides, PAN precursors were also identified as main oxidation products. 3-Penten-2-one is shown to be an example explaining rapid PAN formation within young biomass burning plumes.

The photo-oxidation of myrcene, a monoterpene species emitted by plants, was investigated at atmospheric conditions in the outdoor simulation chamber SAPHIR.

This study measured 106 VOC species using a GC-MS/FID. Meanwhile, the WRF-CMAQ model was used to investigate the nonlinearity of the O3 response to precursor reductions. This study highlights the effectiveness of stringent emission controls in relation to solvent utilization and coal combustion. However, unreasonable emission reduction may aggravate ozone pollution during control periods. It is suggested that emission-reduction ratios of the precursors (VOC : NOx) should be more than 2.

As products we identified aldehydes and ketones which in turn are known to be responsible for the transportation of NOx species.

Short summary
Gas-phase reaction rate coefficients of OH radicals with four nitrocatechols have been investigated for the first time by using ESC-Q-UAIC chamber facilities. The reactivity of all investigated nitrocatechols is influenced by the formation of the intramolecular H-bonds that are connected to the deactivating electromeric effect of the NO2 group. For the 3-nitrocatechol compounds, the electromeric effect of the
freeOH group is diminished by the deactivating E-effect of the NO2 group.
Gas-phase reaction rate coefficients of OH radicals with four nitrocatechols have been...
