This study measured the seasonal particulate matter (PM) and ammonia (NH3) emission concentrations of laying hen houses to calculate the emission factors. The PM and NH3 concentrations were measured according to the Vera test protocol. PM10 and PM2.5 concentrations tended to be low in the summer at 80.0 μg/m3 and 11.3 μg/m3, respectively, and the concentrations changed when the season changed from summer to fall or winter to spring. From November to January, the PM10 and PM2.5 concentrations at the inlet were 346.1-581.1 μg/m3 and 79.8-128.0 μg/m3, respectively, which was higher than at other times, and there was no significant difference in concentration between the inlet and exhaust during this period. The inlet NH3 concentration was 0 ppm in all periods, and the emission concentration was highest in August. The PM10 emission factor was low from November to January, and the PM2.5 emission factor was low in December and from June to August. The NH3 emission factor was low in June. The annual emission factor of PM10, PM2.5, and NH3 in this study were 0.014 kg/head/y, 0.0021 kg/head/y, and 0.158 kg/head/y, respectively.
