Vehicular Ammonia Emissions Significantly Contribute to Urban PM2.5 Pollution in Two Chinese Megacities

Yunjie Wang et al.

Summary: Previous studies have mainly focused on agricultural ammonia emissions and neglected the impact of vehicular ammonia emissions on air quality in cities. This study developed high-resolution emission inventories for Beijing and Shanghai based on traffic data and simulated the contribution of vehicular ammonia emissions to PM2.5 concentrations. It was found that vehicular ammonia emissions accounted for a significant proportion of total anthropogenic ammonia emissions in urban areas, and could contribute to approximately 3% of urban PM2.5 concentrations during winter. Controlling vehicular ammonia emissions is an effective measure to mitigate urban PM2.5 pollution in the future.

Vehicular ammonia emissions: an underappreciated emission source indensely populated areas

Yifan Wen et al.

Summary: This study found that on-road ammonia (NH3) emissions in urban areas of China play a significant role in the formation of fine particulate matter (PM2.5) and pose severe risks to human health. The study also revealed that vehicular NH3 emissions are highly concentrated in densely populated areas, even surpassing agricultural emissions. These findings provide valuable insights into the absolute value and relative importance of on-road NH3 emissions in different regions, seasons, and population densities in China.

???????A dynamic ammonia emission model and the online coupling with WRF-Chem(WRF-SoilN-Chem v1.0): development and regional evaluation in China

Chuanhua Ren et al.

Summary: The volatilization of ammonia (NH3) from fertilizer application and livestock wastes is a major source of nitrogen losses in agricultural ecosystems and atmospheric NH3. However, current emission inventory and atmospheric models poorly describe this phenomenon. To address this, a dynamic NH3 emission model is developed, which calculates the emission rate interactively with varying meteorological and soil conditions. This model, evaluated against field measurements, shows improved performance in simulating NH3 flux and concentration in China. The coupling of soil emission with meteorology provides a better understanding of NH3 emission evolution and its contribution to atmospheric chemistry.

Environmental benefits and household costs of clean heating options in northern China

Mi Zhou et al.

Summary: This study analyzes the air-quality, health, and carbon interdependencies of different heating options in northern China, finding substantial benefits in air quality and health from clean heating options, along with increased heating costs. By 2030, heat pumps show the largest health-carbon synergies among the options analyzed, despite high capital costs, they have lower operating costs and are competitive for long-term use. Increased subsidies for heat pumps can further improve air quality and carbon mitigation in the clean heating transition.

High-Resolution Ammonia Emissions from Nitrogen Fertilizer Application in China during 2005-2020

Youfan Chen et al.

Summary: It is important to accurately estimate ammonia emission in order to quantify secondary inorganic aerosol formation and reactive nitrogen deposition. This study compiles a long-term (2005-2020) high-resolution ammonia emission inventory for synthetic fertilizer in China, taking into account various factors that influence emission. The results show that ammonia emissions are highest in the eastern and southwestern regions of China, with peak emissions occurring in spring and summer. Over the long-term, emissions from synthetic fertilizer have increased initially but remained stable from 2008 to 2012, and then started to decrease in 2020.

Summary: Ammonia, the most important alkaline gas in the atmosphere, has negative effects on biodiversity, ecosystems, soil acidification and human health. This study used satellite data to analyze the changes in NH3 concentrations, estimate surface NH3 concentrations and NH3 emissions in China, and found that satellite-derived NH3 emissions have a high predictive power over multiple temporal and spatial scales.

Yixin Guo et al.

Summary: This study examines the implications of four potential dietary shifts in China on air pollution, GHG emissions, carbon storage loss, water use, and human health. The results show that replacing red meat with soy benefits the environment, while adopting the Chinese Dietary Guideline and EAT-Lancet diets can prevent premature deaths. However, these dietary shifts also increase water use and GHG emissions.

The nonlinear response of fine particulate matter pollution to ammonia emission reductions in North China

Zehui Liu et al.

Summary: Recent Chinese air pollution actions have significantly lowered PM2.5 levels in North China through controlling SO2 and NOx emissions, but unregulated NH3 emissions pose a challenge. Reductions in NH3 emissions can greatly mitigate PM2.5 pollution. NH3 emission control should be considered in conjunction with SO2 and NOx emission controls when designing strategies to mitigate PM2.5 pollution.

Martin Van Damme et al.

Summary: The study utilized infrared satellite data to reveal a significant global increase in NH3 concentration over the past 11 years, driven primarily by regions in East Asia, Africa, North America, and Europe, with a decrease observed in southwestern India. National trends in NH3 emissions were analyzed in relation to changing factors such as anthropogenic and pyrogenic NH3 emissions, meteorological conditions, and sulfur and nitrogen oxides emissions impacting NH3 atmospheric lifetime. Additionally, a case study on the 'Dutch Nitrogen crisis' of 2019 in the Netherlands was conducted.

Effects of reactive nitrogen gases on the aerosol formation in Beijing from late autumn to early spring

Zhang Wen et al.

Summary: The study in Beijing during cold days found that NH3 and NO3- were the predominant components in PM2.5, with total NHx exceeding the neutralization capacity for acid compounds. Aerosol pH decreased and concentrations of all species increased during haze episodes, with gas fractions shifting towards their corresponding particle phases. High levels of aerosol pollution were associated with elevated NH3 and HNO3 concentrations in the atmosphere.

Youfan Chen et al.

Summary: The study found small changes in total Chinese anthropogenic NH3 emissions, but large changes in Chinese NO (x) and SO2 emissions. Chinese NO (x) emissions peaked around 2011 and declined by 22% during 2011-2015, while Chinese SO2 emissions declined by 55% in 2015 relative to 2007. The increase in atmospheric NH3 levels in eastern China since 2011 was mainly driven by rapid reductions in SO2 emissions.

Control of particulate nitrate air pollution in China

Shixian Zhai et al.

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.
