Summary: Coal burning is a major anthropogenic source of air pollutants, and coal-fired industrial boilers are a significant challenge for China's carbon peaking and carbon neutrality policies. This study establishes an emission inventory and uses models to analyze the emissions of air pollutants and greenhouse gases from coal-fired industrial boilers. The driving forces behind emission trends are quantified, and future emission projections are made. The results show that policy adjustments have a significant impact on pollutant emissions, and control technology is a key factor in reducing emissions.

Summary: Emission inventory is crucial for designing effective emission control strategies. However, there is an imbalance in the development of CO2 and air pollutant emission inventories in China, hindering collaborative control strategies. This study developed a unified emission inventory including both CO2 and air pollutants, and used spatial mapping methods to identify co-hotspots at a high spatial resolution. The results showed that the stationary combustion and transportation sectors were the major emitters, and the top 10% emission grids contributed the majority of the emissions.

Summary: India's Indo-Gangetic Plain (IGP) region has become a global hotspot of air pollution, with stubble burning in northern India causing concern. This study analyzed the diurnal variation of air pollutants in Haryana, India, for the first time and identified the sources of emissions during different seasons. The study found that peak concentrations of particulate matter were highest in Zone 2, which includes highly polluting districts with industries like thermal power plants and stainless steel production. The lowest concentrations of pollutants were found in late afternoon hours during winter, pre-monsoon, and post-monsoon seasons due to decreased traffic volume and favorable dispersion conditions.

Summary: Toxic exhaust emissions from vehicles using petroleum-derived fuel contain harmful components above acceptable levels, while vehicles powered by liquefied petroleum gas produce relatively fewer harmful emissions. Despite this, the widespread use of liquefied petroleum gas vehicles due to their low cost leads to significantly increased exhaust emissions, spreading pollutants into the atmosphere uncontrollably and causing environmental issues.

Summary: Construction machinery is a significant contributor to air pollution. This study estimated the emissions from construction machinery in Beijing from 2015 to 2019. The results showed a decrease in emissions of hydrocarbons, carbon monoxide, nitrogen oxides, particulate matter, and carbon dioxide over the five-year period. Loaders and machinery with a mean power above 75 kW were the largest contributors to emissions, and Tongzhou, Shunyi, and Changping Districts contributed the most emissions in 2019. These findings provide valuable data for developing strategies to improve air quality and address climate change.

Summary: The pollution of sediments around Lu Ban Island poses a serious environmental threat to human health. The study analyzed the concentration, distribution, and correlation of potential toxic elements in the sediments, as well as the potential ecological risks. The results showed a linear relationship between the concentration of potential toxic elements and the reciprocal of depth. The sediments above -0.40m were found to have a moderate ecological risk, mainly contributed by potential toxic elements from fish cage culture.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
