In this study, different soot particles were analyzed to better understand their behavior. It was discovered that water-soluble substances in soot facilitate water adsorption at low humidity while increasing the number of water layers at high humidity. Soot from organic fuels exhibits hygroscopicity influenced by organic carbon and microstructure. Additionally, the presence of sulfate ions due to the oxidation of SO2 enhances soot's hygroscopicity.

Nitrogen dioxide (NO2) is a trace gas which is important for atmospheric chemistry and may affect human health. To understand processes leading to harmful concentrations, it is important to monitor NO2 concentrations near the surface and higher up. To this end, a Pandora instrument has been installed in Beijing. An overview of the first year of data shows the large variability on diurnal to seasonal timescales and how this is affected by wind speed and direction and chemistry.

Effects of photochemical aging on the formation and evolution of summertime secondary aerosol were systematically investigated in a suburb of Beijing. Higher PM1 concentration accompanied longer photochemical age (ta). Sulfate and more-oxidized OOA formation were significantly sensitive to the increase in ta, and their contributions were greatly enhanced at elevated ta levels. Our results suggested that photochemical aging process played a crucial role in PM1 and O3 pollution in summertime.

This study found that the coexisting NO2 and/or C2H2 had significant influences on heterogeneous oxidation of SO2 due to the ubiquitous interactions between organic and inorganic species, and their effects were different under dark conditions or with UV irradiation. The experimental results of this study highlighted the requirement to consider the influence of coexisting organics and other inorganic gases in the heterogeneous oxidation kinetics of SO2.

Effects of SO2 and NH3 on SA formation from unburned gasoline vapor were investigated in a 30 m3 smog chamber. With the increase in SO2 and NH3 concentrations, formation of SA and each of its chemical species was promoted. Meanwhile, NPF and particle size growth were also significantly enhanced. This work indicates that gasoline evaporation emissions will be a significant source of SA and sulfur- and nitrogen-containing organics, especially in the presence of high concentrations of SO2 and NH3.

The effect of SO2 at atmospheric levels on SOA formation and its oxidation state during 2-methoxyphenol photooxidation was investigated with various inorganic seed particles. The presence of SO2 increased SOA yield and oxidation state, suggesting that the functionalization reaction should be more dominant than the oligomerization reaction. SO2 and seed particles were found to have a synergetic contribution to SOA formation. The results demonstrate the important role of SO2 in SOA formation.

We extensively compare various cluster-dynamics-based parameterizations for sulfuric acid–dimethylamine nucleation and identify a newly developed parameterization derived from Atmospheric Cluster Dynamic Code (ACDC) simulations as being the most reliable one. This study offers a valuable reference for developing parameterizations of other nucleation systems and is meaningful for the accurate quantification of the environmental and climate impacts of new particle formation.

Methane (CH4) is a potent greenhouse gas. Northern China contributes a large proportion of CH4 emissions yet large observation gaps are existed. Here we compiled a comprehensive dataset which is publicly available including ground-based, satellite-based, inventory and modeling results, to show the CH4 concentrations, enhancements and spatial-temporal variations. The data can benefit the research community, and policy makers for future observations, atmospheric inversions and policy-making.

The nucleation of iodic acid (HIO3) and iodous acid (HIO2) was proven to be critical in marine areas. However, HIO3–HIO2 nucleation cannot effectively derive the rapid nucleation in some polluted coasts. We find a significant enhancement of dimethylamine (DMA) on the HIO3–HIO2 nucleation in marine and polar regions with abundant DMA sources, which may establish reasonable connections between the HIO3–HIO2 nucleation and the rapid formation of new particles in polluted marine and polar regions.

Iodic acid (HIO3) nucleates with iodous acid (HIO2) efficiently in marine areas; however, whether methanesulfonic acid (MSA) can synergistically participate in the HIO3–HIO2-based nucleation is unclear. We provide molecular-level evidence that MSA can efficiently promote the formation of HIO3–HIO2-based clusters using a theoretical approach. The proposed MSA-enhanced iodine nucleation mechanism may help us to deeply understand marine new particle formation events with bursts of iodine particles.

Atmospheric new particle formation (NPF) is a dominant source of atmospheric ultrafine particles. In urban environments, traffic emissions are a major source of primary pollutants, but their contribution to NPF remains under debate. During the COVID-19 lockdown, traffic emissions were significantly reduced, providing a unique chance to examine their relevance to NPF. Based on our comprehensive measurements, we demonstrate that traffic emissions alone are not able to explain the NPF in Beijing.

The influence of photochemical loss of volatile organic compounds (VOCS) on O3 formation is investigated using an observation-based model. The sensitivity regime of ozone formation might be misdiagnosed due to the photochemical loss of VOCs in the atmosphere. The contribution of local photochemistry is underestimated regarding O3 pollution when one does not consider the photochemical loss of VOCs.

This study investigates the connection between organic aerosol (OA) molecular composition and particle absorptive properties in autumn in Beijing. We find that the molecular properties of OA compounds in different episodes influence particle light absorption properties differently: the light absorption enhancement of black carbon and light absorption coefficient of brown carbon were mostly related to more oxygenated OA (low C number and four O atoms) and aromatics/nitro-aromatics, respectively.

We characterized the connection between new particle formation (NPF) events in terms of frequency, intensity and growth at a near-highway location in central Beijing and at a background mountain site 80 km away. Due to the substantial contribution of NPF to the global aerosol budget, identifying the conditions that promote the occurrence of regional NPF events could help understand their contribution on a large scale and would improve their implementation in global models.

We performed experiments in the CLOUD chamber at CERN at low temperatures to simulate new particle formation in the upper free troposphere (at −30 ºC and −50 ºC). We measured the particle and gas phase and found that most of the compounds present in the gas phase are detected as well in the particle phase. The major compounds in the particles are C8–10 and C18–20. Specifically, we showed that C5 and C15 compounds are detected in a mixed system with isoprene and α-pinene at −30 ºC, 20 % RH.

The mechanisms and kinetics of particulate sulfate formation in the atmosphere are still open questions although they have been extensively discussed. We found that uptake of SO2 is the rate-determining step for the conversion of SO2 to particulate sulfate. NH4NO3 plays an important role in AWC, the phase state of aerosol particles, and subsequently the uptake kinetics of SO2 under high-RH conditions. This work is a good example of the feedback between aerosol physics and aerosol chemistry.

We find that ammonium nitrate and aerosol water content contributed most during low mixing layer height conditions; this may further trigger enhanced formation of sulfate and organic aerosol via heterogeneous reactions. The results of this study contribute towards a more detailed understanding of the aerosol–chemistry–radiation–boundary layer feedback that is likely to be responsible for explosive aerosol mass growth events in urban Beijing.

We observed significant concentrations of gaseous HBr and HCl throughout the winter and springtime in urban Beijing, China. Our results indicate that gaseous HCl and HBr are most likely originated from anthropogenic emissions such as burning activities, and the gas–aerosol partitioning may play a crucial role in contributing to the gaseous HCl and HBr. These observations suggest that there is an important recycling pathway of halogen species in inland megacities.

Fog, cloud and haze are very common natural phenomena. Sulfuric acid (SA) is one of the key compounds forming those suspended particles, technically called aerosols, through gas-to-particle conversion. Therefore, the concentration level, source and sink of SA is very important. Our results show that ozonolysis of alkenes plays a major role in nighttime SA formation under unpolluted conditions in urban Beijing, and nighttime cluster mode particles are probably driven by SA in urban environments.

It is difficult to directly observe the COVID-19 signals in CO2 due to the strong weather induced variations. Here, we determined the on-road CO2 concentration declines in Beijing using mobile observatory data before (BC), during (DC) and after COVID-19 (AC). We chose trips with the most similar weather and calculated the enhancement, the difference between on-road and the city “background”. We showed a clear on-road CO2 decrease in DC, which is consistent with the emissions reductions in DC.

Understanding of the chemical and physical processes leading to atmospheric aerosol particle formation is crucial to devising effective mitigation strategies to protect the public and reduce uncertainties in climate predictions. We found that the photolysis of nitrous acid could promote the formation of organic and nitrate aerosol and that traffic-related emission is a major contributor to ambient nitrous acid on haze days in wintertime in Beijing.

By applying both OA PMF and size PMF at the same urban measurement site in Beijing, similar particle source types, including vehicular emissions, cooking emissions and secondary formation-related sources, were resolved by both frameworks and agreed well. It is also found that in the absence of new particle formation, vehicular and cooking emissions dominate the particle number concentration, while secondary particulate matter governed PM2.5 mass during spring and summer in Beijing.

We rely on sulfuric acid measurements in four contrasting environments, Hyytiälä, Finland; Agia Marina, Cyprus; Budapest, Hungary; and Beijing, China, representing semi-pristine boreal forest, rural environment in the Mediterranean area, urban environment, and heavily polluted megacity, respectively, in order to define the sources and sinks of sulfuric acid in these environments and to derive a new sulfuric acid proxy to be utilized in locations and during periods when it is not measured.

Highly oxygenated organic compounds (HOMs) have been identified as key vapors involved in atmospheric new-particle formation (NPF). The molecular distribution, HOM yield, and NPF from α-pinene oxidation experiments were measured at the CLOUD chamber over a wide tropospheric-temperature range. This study shows on a molecular scale that despite the sharp reduction in HOM yield at lower temperatures, the reduced volatility counteracts this effect and leads to an overall increase in the NPF rate.

Sulfuric acid is a major atmospheric vapour for aerosol formation. If new particles grow fast enough, they can act as cloud droplet seeds or affect air quality. In a controlled laboratory set-up, we demonstrate that van der Waals forces enhance growth from sulfuric acid. We disentangle the effects of ammonia, ions and particle hydration, presenting a complete picture of sulfuric acid growth from molecular clusters onwards. In a climate model, we show its influence on the global aerosol budget.

In this study, we focus on explaining the concentration variations in the observed particle modes, by relating them to the potential aerosol sources and sinks, and on understanding the connections between these modes. Interestingly, even in the atmospheric cocktail in urban Beijing, secondary new particle formation (NPF) drives the particle number concentration, especially in the sub-3 nm range. We found that the total number concentration is ~ 4 times higher on NPF days than on haze days.

During production and use of carbon nanomaterials, they are prone to enter the environment and ultimately the human body, and subsequently to pose a risk of adverse health effects. This work has for the first time found that epoxide is highly active to form ROS, possibly leading to a strong oxidation stress to humans, while carboxylation and hydroxylation have little influence on the oxidation potential. This suggests that more attention should be paid to epoxide-containing carbon nanomaterials.

Effects of SO2 and NH3 on SA formation from unburned gasoline vapor were investigated in a 30 m3 smog chamber. With the increase in SO2 and NH3 concentrations, formation of SA and each of its chemical species was promoted. Meanwhile, NPF and particle size growth were also significantly enhanced. This work indicates that gasoline evaporation emissions will be a significant source of SA and sulfur- and nitrogen-containing organics, especially in the presence of high concentrations of SO2 and NH3.

The effect of SO2 at atmospheric levels on SOA formation and its oxidation state during 2-methoxyphenol photooxidation was investigated with various inorganic seed particles. The presence of SO2 increased SOA yield and oxidation state, suggesting that the functionalization reaction should be more dominant than the oligomerization reaction. SO2 and seed particles were found to have a synergetic contribution to SOA formation. The results demonstrate the important role of SO2 in SOA formation.

The rate constant and SOA formation for the OH-initiated reaction of eugenol were studied for the first time in an oxidation flow reactor. Significant SOA formation was observed, and SOA yield depended on precursor concentration and OH exposure. SO2 and NO2 both enhanced SOA yields. In addition, NO2 participated in OH-initiated reaction and produced organic nitrates. The results could be helpful for further understanding SOA formation from the atmospheric oxidation of methoxyphenols.

Gaseous sulfuric acid is one of the key precursors for atmospheric new particle formation processes, but its measurement remains challenging. This work develops an estimation method for the gaseous sulfuric acid concentration in an urban environment in China using multiple atmospheric variables that are easier to measure.

The interactive effects between inorganic and organic species under highly complex pollution conditions remain uncertain and were studied in a smog chamber. This study indicated that the synergistic formation of secondary inorganic and organic aerosol might increase the secondary aerosol load in the atmosphere and contribute haze pollution in eastern China. These synergistic effects were related to the heterogeneous process on aerosol surface and need to be considered in air quality models.

It is unclear about the role of mineral dust in the atmospheric chemistry of amines. Uptake by kaolinite has been found as an innegligible sink of amines based on the measured kinetics in the temperature range of 232–300 K. It reveals that uptake by mineral dust should be considered in models simulating the chemical cycle of amines in the atmosphere in the future. The results will also aid in understanding the possible impacts of amines on human health, air quality, and climate effects.

Various realistic parameters (ambient temperature, wind speed, soil acidity, synthetic fertilizer types, etc.) were considered in these inventories to synthetically refine the emission factors of ammonia volatilization according to local agricultural practice.
This paper shows the interannual trend and spatial distribution of ammonia emissions in details over recent decades.

A novel ultrasensitive VUV photoionization mass spectrometer is developed to monitor trace-level VOCs in real time. By employing a light baffle in the photoionizer, the background noise is efficiently suppressed and the detection limit reaches to a low pptv level. Continuous monitoring of VOCs in urban air demonstrates the strength of this instrument. This study reveals that the new technique may have the capability of ranking with the PTR-MS for field measurements.

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.

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.

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.

Halogenated polycyclic aromatic hydrocarbons (XPAHs) are emerging pollutants. 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.

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.

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.

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.

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.

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
This work highlights the opposing effects of primary and secondary H2SO4 on both secondary organic aerosol (SOA) formation and constitutes. Our findings revealed that a substantial increase in secondary H2SO4 particles promoted the SOA formation of ethyl methacrylate with increasing SO2 in the absence of seed particles. However, increased primary H2SO4 with seed acidity enhanced ethyl methacrylate uptake but reduced its SOA formation in the presence of seed particles.
This work highlights the opposing effects of primary and secondary H2SO4 on both secondary...
