Summary: Atmospheric ammonia (NH3) plays a crucial role in the formation of secondary inorganic aerosols. This study aimed to understand the temporal variations, sources, and environmental influences of NH3 through a comprehensive field campaign in the North China Plain. The results showed that residential coal combustion was the main source of NH3, leading to high average concentrations. The study also found that NH3 had an impact on HONO production, and controlling NH3 emissions could improve air quality in rural areas.

Summary: Studies show persistent particulate-nitrate pollution in the North China Plain despite rapid reduction in NOx emissions. Analysis suggests N2O5 uptake in aerosols and clouds as the dominant nitrate-production pathway in wintertime Beijing, limited by ozone under high-NOx-high-PM2.5 conditions. Policies reducing ozone concentrations may effectively decrease nitrate formation during wintertime haze events.

Summary: NO3 radicals can clean atmospheric primary contaminants, but may also affect the formation of secondary organic aerosol and nitrate, potentially worsening air quality. Field observations showed average NO3 mixing ratios of 21 ppt with a maximum of 104 ppt, with higher levels of PM2.5 and relative humidity leading to increased NO3 loss.

Summary: The study found that high concentrations of PAN in winter are mainly caused by VOC aging processes involving OH oxidation or photolysis, rather than ozonolysis pathways. Additionally, heterogeneous reactions on aerosols supplied key photochemical oxidants, promoting the formation of OVOC and PAN, explaining the intercorrelation between PM2.5-OVOC-PAN.

Summary: Frequent severe haze events with high levels of fine aerosols in the North China Plain have profound impacts on human health, weather, and climate. The haze formation mechanisms involve sources, formation, and transformation of aerosol species. Recent advances have shown the importance of new particle formation and aerosol growth driven by photochemistry and aqueous chemistry in understanding secondary aerosol formation.

Summary: This study examines the impact of local meteorology on the production of ClNO2 and N2O5, two important atmospheric compounds. The results show that atmospheric turbulence, precipitation (snow, rain) and fog, and ground cover (snow-covered and bare ground) have significant effects on the abundances of ClNO2 and N2O5. These findings highlight the importance of considering these meteorological factors in understanding atmospheric chemistry.

Summary: Aerosol nitrate has become the most abundant compound in aerosol pollution in eastern China. The response of nitrate to nitrogen oxide (NOx) reduction is still unclear despite the government's stringent policies. The study found that elevated dinitrogen pentoxide (N2O5) hydrolysis is responsible for the observed increase in nitrate.

Summary: Rural areas in the winter in North China Plain experience severe haze pollution due to aerosol particles, particularly organic aerosol (OA), but the sources and processes of these particles are not well understood. Real-time measurements in a representative rural site in 2019 showed that primary sources of OA include traffic emissions, coal combustion, and biomass burning, while secondary OA from photochemical and aqueous-phase processing was more dominant. The study also observed enhanced secondary formation in winter 2019 compared to winter 2018, with changes in aerosol composition and size distributions during fog events.

Summary: Accurate identification and quantitative source apportionment of fine particulate matter (PM2.5) is essential to reduce pollution. The study in North China Plain found that during a haze event, local emissions contributed 36.3% of PM2.5 mass in Beijing, while nonlocal emissions contributed 63.7%. Nonlocal emissions have a greater impact on PM2.5 levels in Beijing and Tianjin, while local emissions play a larger role in Hebei and Shandong.

Summary: During the winters between 1985 and 2015, the North China Plain experienced heavy haze episodes that coincided with extreme rainfall in southern China. This study uses observations and model simulations to show that anomalous anticyclonic circulation, caused by Rossby wave trains, together with the north-south circulation system, plays a key role in modulating the haze over the North China Plain. Additionally, the study highlights the importance of diabatic heating related to precipitation in driving the north-south circulation system and the formation of haze.

Summary: Despite strict emission control measures implemented since 2013, severe wintertime haze with high levels of secondary aerosols continues to affect the Guanzhong Basin (GZB), China. Researchers have found that heterogeneous nitrous acid (HONO) sources play a significant role in wintertime particulate pollution and atmospheric oxidizing capability (AOC) in the GZB. Decreasing HONO levels or AOC can effectively alleviate the wintertime particulate pollution in the GZB.

Summary: In recent years, ozone pollution has worsened in China, contributing frequently to air pollution problems. This study monitored 117 volatile organic compounds in 13 cities and found that alkanes, halogenated hydrocarbons, aromatics, and oxygenated VOCs were the dominant compounds. These compounds were found to contribute to the formation of ozone. The study also identified sources of VOCs, including solvent usage, gasoline evaporation, vehicle emissions, petrochemical industry, and combustion.

Summary: In this study, the activities of cloud condensation nuclei and the chemical composition of aerosols were measured in Beijing. It was found that the dominant driver of CCN activity shifted from sulfate to nitrate as PM2.5 concentration increased. The degree of internal mixing had a positive effect on CCN activation. The Org/BC ratio, rather than f44 or O:C, showed a good correlation with k(org), and considering korg variations improved the correlation between CCN measurements and bulk chemical compositions.

Summary: Strict restrictions on anthropogenic emissions during the Beijing 2022 Winter Olympics Game provided a unique opportunity to investigate new particle formation events in a highly polluted atmosphere. The study found that nucleation events were enhanced during the games, with higher frequencies and formation rates compared to before and after the games. The results suggest that the presence of amines contributed to the higher formation rates, and sulfuric acid and organic compounds played important roles in particle growth.

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.
