Evaluation of Ammonia Emission Model Using Laboratory Emission Data

Abstract

Emissions of ammonia (NH3) from human activities is of importance a contributing factor as an aspect of the generation of

particulate matter (PM) and may contribute to air quality degradation on a regional and continental scale. Due to the diversity of

emission sources and environmental conditions, quantifying ammonia emissions from soil origin is not fully understood. The

objective of this study is to evaluate the regional emission of ammonia using the Ammonia Emission Estimation System (AEES)

for determining the emissions from agricultural areas, where one of the major sources of ammonia emission. Using the national

land cover map and laboratory-based emission factors, ammonia emissions were calculated for each administrative region and

verified through comparative analysis with the Clean Air Policy Support System (CAPSS) ammonia emission data. The national

ammonia emission was analyzed to be 38470.2 ton/year, which is higher than the CAPSS total emission of 19566.1 ton/year. As a

result of comparing the two data by different provinces, it was found that the Pearson correlation coefficients (r) were 0.85 and

0.91, respectively, indicating a relatively high correlation. The results of this study can be used as basic data to support the

management of ammonia emission and the implementation of long-term air quality-related policies in the future.
