Summary: Grassland fires in Hulun Buir decreased significantly from 2010 to 2019, mostly occurring in spring and autumn between 1990 and 2019. Among the meteorological factors, wind speed, relative humidity, and sunshine hours showed the strongest correlation with burned areas. Relative humidity had the biggest influence on burned area in both long-term and short-term effects. The ARDL models demonstrated the sensitivity of meteorological factors related to fire and can effectively study trends in grassland fire burning area.

The emission variations of different pollutants were analyzed spatially and temporally. Three emission reduction scenarios were proposed, and the elimination of HDDTs that follow old emission standards and the installation of tailpipe treatment devices were found to be the most effective measures. The results of this study can provide useful information for policymakers to reduce vehicle pollution in Northeast China.

In this study, a hybrid model approach was used to identify ecological corridors for four waterbird species in Northeast China. The research found that the least cost routes and pinch points had the potential to become waterbird ecological corridors, but their structure and distribution varied due to differences in the number and distribution of waterbird core habitat patches.

Summary: The Australian bushfires in late 2019 and early 2020 had a significant impact on the local and global atmosphere due to high temperatures and drought. Using a global atmospheric chemistry transport model and observations, this study assessed the substantial influence of bushfire emissions on PM2.5 in Australia. The increase in biomass-burning emissions during December 2019 resulted in substantial increases in PM2.5 levels in major cities like Canberra, Sydney, Newcastle, Brisbane, and Melbourne.

Summary: Due to anthropogenic emission reductions, the mass concentration of fine particulate matter (PM2.5) in China has significantly decreased in recent years. This study focused on the Huaihe River Basin (HRB) in China to investigate the reasons behind this decrease. The results showed that meteorological conditions and emission reductions both played a positive role in the decrease of PM2.5 concentration in the HRB, with contributions of 30.09% and 69.91% respectively. It was suggested that more efforts should be made to control NO2 emissions in the HRB to further reduce PM2.5.

Summary: Due to differences in topography, water vapor distribution, and emission structures, air pollution in Xinjiang exhibits remarkable spatial heterogeneity. The region is divided into four areas: a clean area in the north, a heavily polluted area in the Urumqi-Changji-Shihezi region, a moderately polluted area in the north of southern Xinjiang, and a severely polluted area in the south of southern Xinjiang. The study reveals that air pollution in typical regions of Xinjiang has become more severe in recent years, highlighting the growing importance of pollution prevention and control in the region.

Summary: This study uses the Nested Air Quality Prediction Modeling System to investigate the effect of typhoon Hagupit on the wet deposition of nitrogen in eastern coastal China. The results reveal an enhancement mechanism of nitrogen deposition related to the 'pumping effect' of the typhoon, where air pollutants are pumped into higher altitudes and deposited via the in-cloud scavenging process. This study updates our understanding of the source-receptor relationship on atmospheric wet deposition caused by tropical cyclones.

Summary: This study investigates the chemical differences between submicron aerosol (PM1) species and fine particles (PM2.5) in Beijing, China, using a high-resolution AMS and a time-of-flight ACSM. The results show that aerosol species in PM2.5 are highly correlated with those in PM1, but the PM1/PM2.5 ratios vary greatly for different species. Nitrate is dominant in PM1, while a significant fraction of sulfate is observed in the PM1-2.5 range. PM1 organics show higher fractions in PM2.5 in summer. The study also compares the source apportionment of organic aerosol (OA) between PM1 and PM2.5, revealing substantial differences in primary and secondary OA composition, especially in winter. Additionally, a parameterized relationship between oxygen-to-carbon ratio and CV f44 is developed, which has implications for studying the oxidation and hygroscopicity properties of OA.

Summary: The study observed the high-resolution dynamic, thermal, and material structures of sea-land breeze circulation (SLB) at the Ningbo coast in the East China Sea. SLB occurred more frequently in spring than in winter, with the horizontal wind speed generally less than 8 m/s and the vertical wind speed less than 0.17 m/s. The circulation heights and dominant heights of sea and land breezes varied between winter and spring. The development of SLB in winter showed distinct differences compared to spring, with a shorter transition process and lower turbulent kinetic energy.

Summary: This study investigated the source, formation, and seasonality of biogenic secondary organic aerosol (BSOA) in Beijing, China from April 2017 to January 2018. BSOA tracers derived from isoprene, monoterpene, and sesquiterpene were measured and showed significant seasonal variations. Isoprene SOA tracers correlated with biomass burning and long-range transport, while sesquiterpene SOA tracer was associated with local biomass burning. These results suggest that BSOA tracers are promising for understanding the source, formation, and seasonality of BSOA.

Summary: This study investigates the photochemical processes between organic coatings and aqueous samples such as fogwater, which contain light absorbing brown carbon (BrC). Through laboratory studies and field observations, it is found that unsaturated fatty acids can interact with aqueous samples, forming organic peroxy radicals and undergoing oxidation pathways. The results also suggest that the interaction between organic acids and hydroxyl radicals (OH) has a higher oxidative capacity than OH alone. In addition, oleic acid is shown to enhance the aqueous oxidation ability by producing oxygen-containing radicals.

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.
