Abstract

Although the discovery of ammonia might trace to earlier Greek or Iranian alchemy, negative consequences of atmospheric ammonia to humans and the environment have only been discovered in the last decades. The global ammonia emissions have irrepressibly increased with the growth of population and anthropogenic activities. Fortunately, extensive research has been conducted with the goal to mitigate the anthropogenic sources of ammonia. The volatilization of nitrogen fertilizers is believed to be the most important anthropogenic source. However, atmospheric ammonia from urban areas has been attributed to vehicles or ammonia slip. Therefore, source apportionment of this trace atmospheric compound is a prerequisite to achieve ammonia mitigation. This review summarizes the current methods applied to source apportionment of atmospheric ammonia including in situ measurement of emission flux, emission inventory, satellite observation, and stable isotope signature. The advantages and drawbacks of these methods are discussed. The reliability of these methods depends on the scale in the field and the characteristics of emission sources. A combination of these methods is necessary to develop reliable models of atmospheric physics and chemistry.
