In this study, the generation and emission characteristics of particulate matter and gaseous matter in a mechanically ventilated layer house wereevaluated. Each concentration of PM10, PM2.5, inhalable dust, respirable dust, and NH3 was measured and compared with occupational limit consideringseasons and respiratory disorder. CAPPS (Clean Air Policy Support System) of the Ministry of Environment proposes the emission factors of PM10,PM2.5, and NH3 for a layer houses however, emission factors are still calculated from foreign factors such as CONINAIR values. As a result, it is urgentto develop national emission factors for domestic layer house. Emission coefficients of the studied mechanically-ventilated layer house in a summerseason were calculated as 0.052 kg/head/year for PM10, about 12% lower than that of CAPSS, and 0.0068±0.0038 kg/head/year for PM2.5, showing nosignificant difference. Emission factor of NH3 was calculated as 0.159±0.031 kg/head/year, about 51% lower than that of CAPSS.
