Summary: The study conducted experiments on secondary organic aerosol (SOA) formation from urban cooking and vehicular sources using a high-resolution time-of-flight aerosol mass spectrometer. Results showed that cooking styles had a greater impact on aged COA mass spectra than oxidation conditions, while oxidation conditions significantly affected aged HOA spectra more than vehicle operating conditions. Mass spectra similarity analysis and positive matrix factorization were used to establish the POA and SOA mass spectra of these sources, and the improved ME-2 model better quantified the contribution of POA and SOA from cooking and vehicular sources compared to traditional ambient PMF results. This work established the vehicle and cooking SOA source profiles for the first time and can be further used in OA source apportionment in the ambient atmosphere.

Summary: By measuring various carbon components in PM2.5, this study examined the sources and differences of carbonaceous aerosols during haze events and non-haze periods in two northern Chinese cities. The results showed that vehicle emissions and levoglucosan were significant contributors to haze pollution, but their contributions varied between cities. Therefore, specific management measures targeting vehicle emissions in Beijing and coal/biomass fuel usage in Xi'an should be implemented to address air pollution.

Summary: Aerosol emissions from spaceflight activities, particularly the injection of black carbon particles into the stratosphere, have a significant impact on stratospheric temperature, circulation, and ozone levels. These climate responses are directly proportional to the emission rates, indicating the sensitivity of the stratosphere to BC injections.

Summary: This study examines the impact of carbon trading pilot policy (CTPP) on carbon emissions (CO2) and air pollution (Ap) using the difference in differences method (DID) utilizing panel data from 30 Chinese areas spanning from 2008 to 2020. The results indicate that CTPP implementation can effectively decrease CO2 and Ap. CTPP can reduce CO2 and Ap through positive incentive effects that promote industrial structure upgrading and drive technological progress. Moreover, CTPP exhibits significant regional variation, with CTPP significantly reducing CO2 in both the eastern and central and western regions. CTPP do not show an effective reduction in Ap in the eastern region, while effectively reduce Ap in central and western regions.

Summary: The Camp Fire in 2018 was a deadly and destructive wildfire in California, causing widespread smoke that threatened the air quality in Northern California. Using the Carbonaceous Aerosol Speciation System, the study measured total carbon, black carbon, and organic carbon in Berkeley to analyze the fire's impact on air quality. During the fire event, black carbon concentrations increased four times above normal levels, and organic carbon increased by approximately ten times. The study also found changes in the characteristics of carbonaceous aerosols over the course of the fire event, with a higher fraction of secondary carbonaceous aerosols observed later on.

Summary: According to the latest Arctic Monitoring and Assessment Programme (AMAP) report, the Arctic has warmed three times faster than the global average and faster than previously thought. Due to limited observations, a research aerosol station has been established on Bely Island in western Siberia to study the Siberian Arctic. The study found that black carbon and other pollutants exhibit apparent seasonal variation in the Arctic, with emissions from burning natural gas being the main contributing source. Emissions from Europe and Asia also have an impact on the pollution in the Arctic.

Summary: PM2.5 samples were collected in Nanchang from October 31 to November 10, 2019, and the carbon components in the aerosols were analyzed. The results showed that coal combustion, vehicle exhaust emissions, and secondary organic carbon formation were major factors contributing to the carbonaceous aerosols in Nanchang. Additionally, particulate brown carbon (BrC) had significant light absorption, even though elemental carbon (EC) was the main light absorption component.

Summary: Through the measurement of optical properties of brown carbon (BrC) in 1-hr time-resolved PM2.5 samples collected during three haze events, it was found that the conversion of low-oxidized water-insoluble BrC into highly oxidized water-soluble BrC occurred during the day. The results showed that aqueous secondary processes were the main contributor to BrC absorption, and changes in meteorological conditions, especially relative humidity, significantly influenced the light-absorbing capacity of BrC.

Summary: This study presents long-term BC deposition and source apportionment data from Russia for the first time, indicating increasing BC fluxes between 1800 and 2014. Radiocarbon analyses show biomass as the main source for BC, with fossil fuel contributions peaking around 1960-1990. The comparison of observed and modeled data suggests the need to update anthropogenic BC emission inventories for Russia and potentially adjust wildfire emission estimates.

Summary: The concentration of fine particulate matter (PM2.5) in China decreased by 30-50% from 2013 to 2018 due to emission controls, but the nitrate component did not decrease effectively. Increased particulate nitrate concentration during winter haze pollution events is attributed to the particulate fraction transitioning from gaseous nitric acid. Reducing ammonia emissions is suggested as an effective method to decrease the nitrate component of fine particulate matter pollution in the North China Plain.

Summary: Fossil fuel combustion is a significant source of black carbon (BC) in urban environments, but personal exposure (PE) and health impacts remain poorly understood due to lack of observational data. This study assessed PE to BC in Trivandrum, India, under home-based and mobility-based exposure scenarios, finding higher inhaled doses in the latter. The findings emphasize the importance of reducing PE to fossil fuel-related particulate emissions in cities for public health improvement.

Summary: Organic aerosols (OA) from the Athabasca oil sands in Canada have a complex effect on climate and health. This study evaluated four volatility distributions using a customized box model and found that vapours from excavated deposits heated to 60 degrees C performed the best among the four evaluated distributions. However, quantifying the specific sources of OA precursors within oil sands operations is necessary.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
