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.

ClNO2 is an important precursor of chlorine radical that affects photochemistry. However, its production and impact are not well understood. Our study presents field observations of ClNO2 at three sites in northern China. These observations provide new insights into nighttime processes that produce ClNO2 and the significant impact of ClNO2 on secondary pollutions during daytime. The results improve the understanding of photochemical pollution in the lower part of the atmosphere.

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.

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.

Based on a field study at Mt. Tai, China, the simultaneous variations of cloud microphysics, aerosol microphysics and their potential interactions during cloud life cycles were discussed. Results demonstrated that clouds on clean days were more susceptible to the concentrations of particle number, while clouds formed on polluted days might be more sensitive to meteorological parameters. Particles larger than 150 nm played important roles in forming cloud droplets with sizes of 5–10 μm.

A vast area in China is currently going through severe haze episodes with drastically elevated concentrations of PM2.5 in winter. Nitrate and sulfate are main constituents of PM2.5, but their formations via NO2 and SO2 oxidation are still not comprehensively understood. Our results found that the gas-phase reaction of NO2 with OH and the heterogeneous hydrolysis of N2O5 play key roles in nitrate formation, and SO2 aqueous-phase oxidation with H2O2 rather than NO2 contributed greatly to sulfate.

NMHCs were measured during wintertime in Beijing to recognize their pollution levels, variation characteristics, and sources. The difference of the diurnal variations in NMHCs between clear days and haze days indicated that the relative contribution of vehicular emissions to NMHCs depended on the pollution status. Both the correlation coefficients of hydrocarbon pairs and PMF analysis revealed that coal combustion was an important source for atmospheric NMHCs, especially on haze days.

The periodic emissions from farmers' activities in the NCP were found to make a great contribution to atmospheric WSIs in Beijing: crop straw burning contributed to K+ in Beijing; coal combustion for heating by farmers in winter and the use of NH4Cl fertilizers in the NCP contributed to Cl− in Beijing. The harvest and soil ploughing in autumn contributed to the regional Ca2+. In addition, the mineral dust greatly accelerated formation of sulfate and nitrate through heterogeneous reactions.

We report eruptive production of nitrous acid (HONO) and NOx (NO + NO2) triggered by iron ions during the photolysis of neonicotinoid insecticide in the air-water interface. This novel previously overlooked source of atmospheric HONO and NOx, may be an important contribution to the global nitrogen cycle and affects the atmospheric oxidizing capacity as well as the climate change.

In this study, combining comprehensive field measurements and a box model, we found NO2 conversion on the ground surface was the most important source for HONO production among the proposed heterogeneous and gas-phase HONO sources. In addition, HONO was found to evidently enhance O3 production and aggravate O3 pollution in summer in China. Our study improved our understanding of the relative importance of different HONO sources and the crucial role of HONO in O3 formation in polluted areas.

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.

Summertime measurements of nitrous acid (HONO) and related parameters were conducted at the foot and the summit of Mt. Tai (1534 m above sea level). We proposed a rapid vertical air mass exchange between the foot and the summit level, which enhances the role of HONO in the oxidizing capacity of the upper boundary layer. Kinetics for aerosol-derived HONO sources were constrained. HONO formation from different paths was quantified and discussed.

Secondary sulfate aerosols are an important component of fine particles in severe air pollution events. We calculated the sulfate formation rates via a state-of-the-art multiphase model constrained to the observed values. We showed that transition metals in urban aerosols contribute significantly to sulfate formation during haze periods and thus play an important role in mitigation strategies and public health measures in megacities worldwide.

Ice formation by particles is an important way of making mixed-phase and ice clouds. We found that particles collected in the marine atmosphere exhibit diverse ice nucleation abilities and mixing states. Sea salt mixed-sulfate particles were enriched in ice-nucleating particles. Selective aging on sea salt particles made particle populations more externally mixed. Characterizations of particles and their mixing state are needed for a better understanding of aerosol–cloud interactions.

In this study, we found that biomass burning (31.0 %) and coal combustion (31.1 %) were the dominant sources of water-insoluble organic carbon in China, with coal combustion sources exhibiting the strongest light-absorbing capacity. Additionally, we propose a light-absorbing carbonaceous continuum, revealing that components enriched with fossil sources tend to have stronger light-absorbing capacity, higher aromaticity, higher molecular weights, and greater recalcitrance in the atmosphere.

The chemical composition of atmospheric particles has shown significant changes in recent years. We investigated the potential effects of changes in inorganics on aerosol water uptake and, thus, secondary organic aerosol formation in wintertime haze based on the size-resolved measurements of non-refractory fine particulate matter (NR-PM2.5) in Xi’an, northwestern China. We highlight the key role of aerosol water as a medium to link inorganics and organics in their multiphase processes.

Organic aerosol is ubiquitous in the atmosphere and largely explains the gap between current levels of fine particulate matter in many cities and the World Health Organization guideline values. This study highlights the dominant contributions of cooking emissions to organic aerosol when marine air prevailed in Hong Kong, which were occasionally overwhelmed by aromatics-derived secondary organic aerosol in continental ouflows.

The determination of ions in the mass spectra of individual particles remains uncertain. We have developed a standard-free mass calibration algorithm applicable to more than 98 % of ambient particles. With our algorithm, ions with ~ 0.05 Th mass difference could be determined. Therefore, many more atmospheric species could be determined and involved in the source apportionment of aerosols, the study of chemical reaction mechanisms, and the analysis of single-particle mixing states.

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

Aerosol particles from mainland can transport to oceans and deposit, providing soluble Fe and affecting phytoplankton growth. Thus, we studied the dissolution process of aerosol Fe and found that photochemistry played a key role in promoting Fe dissolution in clean conditions. RH-dependent reactions were more influential in slightly polluted conditions. These results highlight the distinct roles of two weather-related parameters (radiation and RH) in influencing geochemical cycles related to Fe.

Nitrated aromatic compounds (NACs) and oxygenated derivatives of polycyclic aromatic hydrocarbons (OPAHs) in PM2.5 were examined from an urban area in Beijing during the autumn and winter. The OPAH and NAC concentrations were much higher during heating than before heating. They majorly originated from the combustion of biomass and automobile emissions, and the secondary generation was the major contributor throughout the whole sampling period.

Comprehensive study of optical properties of brown carbon (BrC) in fine aerosols from Tianjin, China, implied that biological emissions are major sources of BrC in summer, whereas fossil fuel combustion and biomass burning emissions are in cold periods. The direct radiation absorption caused by BrC in short wavelengths contributed about 40 % to that caused by BrC in 300–700 nm. Water-insoluble but methanol-soluble BrC contains more protein-like chromophores (PLOM) than that of water-soluble BrC.

Aerosol particles in the atmosphere play a key role in climate change and air pollution. A large number of aerosol particles are formed from the oxidation of volatile organic compounds (VOCs and secondary organic aerosols – SOA). An important field campaign was organized on Réunion in March–April 2019 to understand the formation of SOA in a tropical atmosphere mostly influenced by VOCs emitted by forest and in the presence of clouds. This work synthesizes the results of this campaign.

Quantifying Cl− depletion as a percentage captures seasonal trends in depletion but fails to convey the effects it may have on atmospheric oxidation.

The cumulative number concentration of ice-nucleating particles (INPs) varied from 1.6 × 10−3 to 78.3 L−1 over the temperature range of −5.5 to −29.0 ℃. Biological INPs (bio-INPs) accounted for the majority of INPs, and the proportion exceeded 90% above −13.0 ℃. Planetary boundary layer height, valley breezes, and long-distance transport of air mass influence the abundance of bio-INPs.

To understand how changing emissions have impacted aerosols in remote regions, we measured nitrate and sulfate at Barbados and compared to model predictions from EPA’s Air QUAlity TimE Series (EQUATES). Nitrate was stable except for spikes in 2008 and 2010 due to transported smoke. Sulfate decreased in the 1990s due to reductions of sulfur dioxide (SO2) in the U.S. and Europe, then increased in the 2000s due to anthropogenic emissions from Africa and more efficient oxidation of SO2.

Black carbon (BC) concentration was measured from 211 ship exhaust gas plumes at a remote marine station. Emission factors of BC were calculated in grams/kilograms fuel. Ships using exhaust gas cleaning systems (EGCS) were found to emit 80 % less BC than ships without EGCS. Emission factors were used to model BC emissions as a function of speed to define the effect of speed reduction. BC emissions increased with a decrease in speed from the ship’s service speed.

Based on comprehensive shipborne observations, we found strong links between sea-surface biological materials and the formation of atmospheric fluorescent bioaerosols, cloud condensation nuclei, and ice-nucleating particles over the Arctic Ocean and Bering Sea during autumn 2019. Taking the wind-speed effect into account, we propose equations to approximate the links for this cruise, which can be used as a guide for modeling as well as for systematic comparisons with other observations.

This study investigates the fractional solubility of iron (Fe) in dust particles along the coast of Namibia, a critical region for the atmospheric Fe supply of the South Atlantic Ocean. Our results suggest a possible two-way interplay whereby marine biogenic emissions from the coastal marine ecosystems into the atmosphere would increase the solubility of Fe-bearing dust by photo-reduction processes. The subsequent deposition of soluble Fe could act to further enhance marine biogenic emissions.

Cooking emissions are often an overlooked source of air pollution. We used a mobile lab to measure the characteristics of particles emitted from cooking sites in two cities. Our findings showed that cooking releases a substantial number of fine particles. While most emissions were similar, a bakery site showed distinctive chemical compositions with higher nitrogen compound levels. Thus, understanding the particle emissions from different cooking activities is crucial.

We investigated the chemical composition of atmospheric fine particles, their emission sources, and the potential human health risk associated with trace elements in particles for an urban site in Montréal over a 3-month period (August–November). This study represents the first time that such extensive composition measurements were included in an urban source apportionment study in Canada, and it provides greater resolution of fine-particle sources than has been previously achieved in Canada.

We conducted an investigation of atmospheric aerosols collected in Seoul, South Korea, during the KORUS-AQ campaign on a single-particle basis. We were able to identify their sources, the atmospheric fate, and the impacts of local emissions and long-range transport on aerosol composition. Additionally, we traced potential sources of non-exhaust heavy-metal particles. This comprehensive analysis provides valuable insights into the complex dynamics of urban aerosols.

We investigated short-term source apportionment of PM2.5 utilizing rolling positive matrix factorization (PMF) and online PM chemical speciation data, which included source-specific organic tracers collected over a period of 37 d during the winter of 2019–2020 in suburban Shanghai, China. The findings highlight that by imposing constraints on the primary source profiles, short-term PMF analysis successfully replicated both the individual primary sources and the total secondary sources.

The atmospheric pollution and formation mechanisms of particulate-bound alkyl nitrate in Beijing were studied. C9–C16 long-chain n-alkyl nitrates negatively correlated with O3 but positively correlated with PM2.5 and NO2, so they may not be produced during gas-phase homogeneous reactions in the photochemical process but form through reactions between alkanes and nitrates on PM surfaces. Particulate-bound n-alkyl nitrates strongly affect both haze pollution and atmospheric visibility.

Environmental persistent free radicals (EPFRs) and reactive oxygen species (ROS) play an active role in the atmosphere. We quantified the impact of control measures on EPFRs and ROS and found that strict control measures have effectively reduced their emissions, largely linked to a significant decrease in secondary aerosols. Our findings have great implications for further understanding the formation and sources and for developing future air quality management policies targeting EPFRs and ROS.

We present a molecular size-resolved offline analysis of water-soluble brown carbon collected on an aircraft during FIREX-AQ. The smoke plumes were aged 0 to 5 h, where absorption was dominated by small molecular weight molecules, brown carbon absorption downwind did not consistently decrease, and the measurements differed from online absorption measurements of the same samples. We show how differences between online and offline absorption could be related to different measurement conditions.

Marine carbohydrates are produced in the surface of the ocean, enter the atmophere as part of sea spray aerosol particles, and potentially contribute to the formation of fog and clouds. Here, we present the results of a sea–air transfer study of marine carbohydrates conducted in the high Arctic. Besides a chemo-selective transfer, we observed a quick atmospheric aging of carbohydrates, possibly as a result of both biotic and abiotic processes.

We investigate the contribution of grown new particles to Nccn at a rural mountain site in the North China Plain. The total particle number concentrations (Ncn) observed on 8 new particle formation (NPF) days were higher compared to non-NPF days. The Nccn at 0.2 % supersaturation (SS) and 0.4 % SS on the NPF days was significantly lower than on non-NPF days. Only one of eight NPF events had detectable net contributions to Nccn at 0.4 % SS and 1.0 % SS with increased κ values.

We investigated aerosol composition, sources, and the interaction between secondary organic aerosol (SOA) and clouds at a regional mountain site in southeastern China. Clouds efficiently scavenge more-oxidized SOA; however, cloud evaporation leads to the production of less-oxidized SOA. The unexpectedly high presence of nitrate in aerosol particles indicates that nitrate formed in polluted areas has undergone interactions with clouds, significantly influencing the regional background site.

Soot particles, also known as black carbon (BC), have important implications for global climate and regional air quality. After the particles are emitted, BC can be coated with other material, impacting the aerosol properties. We selectively measured the composition of particles containing BC to explore their sources and chemical transformations in the atmosphere. We focus on a persistent, multiday fog event in order to study the effects of chemical reactions occurring within liquid droplets.

Short-term strict emission control can improve air quality but the effectiveness requires assessment. During 2021 summer COVID-19 lockdown in Yangzhou, we showed that the PM2.5 level did not decrease with decrease of gaseous pollutants as aged black carbon-containing particles increased substantially, due to enhanced atmospheric oxidizing capacity and high relative humidity. The results highlights the importance of a regionally balanced control strategy for future air quality management.

Short summary
The North China Plain in winter frequently suffers from severe haze pollution which is mainly ascribed to elevation of PM2. 5. Although the government has performed a series of control measures for major pollution sources, the PM2. 5 levels were still above 1000 ug m-3 in some areas of the Beijing–Tianjin–Hebei region. In this study, we found that residential coal combustion made an evident contribution to PM2. 5 in the region, the contributions of which were estimated to be about 32–58 %.
