Characteristic of Atmospheric Ammonia in Swine Breeding Area

In this study, the purpose is to collect basic data on the characteristics of NH3 emission in domestic agricultural and livestock areas and the distribution of concentrations by season, monthly, and hourly. Representative regions where agriculture and livestock are developed were selected and the concentration of NH3 and the meteorological environment were measured for one year in the atmosphere. As a result, the diurnal patten of the two observation site was clear. In both observation sites, it showed a diurnal trend that increased continuously from night to morning and decreased during the day. Also, in the case of Boryeong city (BR), although the diurnal trend of spring and autumn was not different, the highest concentration was high compared to other seasons relatively. This seems to be due to high concentration of NH3 was observed in agricultural land of the spring and autumn seasons. It was found that in order to reduce the concentration of NH3, it is necessary to select an efficient management method through analysis.
