Sources, Variations, and Effects on Air Quality of Atmospheric Ammonia
Purpose of Review
As the most abundant alkaline trace gas in the atmosphere, NH3 plays a critical role in the formation of atmospheric particulate matter and nitrogen cycling in ecosystems. NH3 emissions have been increasing globally over the past few decades. To provide a clearer understanding of atmospheric NH3, this paper presents a systematic review of the literature on the sources and variability of atmospheric NH3 and describes the contribution of atmospheric NH3 to PM2.5.
Recent Findings
(1) The primary source of atmospheric NH3 emissions is agriculture; other sources include combustion-related emissions and volatilization from soil and oceans. However, recent studies have revealed the major role of nonagricultural sources in urban areas. (2) The spatiotemporal variability of atmospheric NH3 is complex, and its mechanisms are not entirely clear. (3) Atmospheric NH3 can participate in multiple atmospheric chemical processes and to the formation of fine particulate matter.
Summary
This review summarizes the latest knowledge on the sources and variability of atmospheric NH3 and highlights the necessity of controlling atmospheric NH3 emissions. However, significant knowledge gaps still exist in understanding the sources, trends, and effects of atmospheric NH3. Therefore, further research is essential to investigate the influencing factors and environmental effects of atmospheric NH3 concentrations, providing a scientific basis for the development of effective NH3 control strategies.
