The purpose of this study is to investigate concentration and emission factor of 22 odorous compounds, which are regulated by the domestic act, emitted from poultry buildings by on-site investigation. The odorous compounds which were detected in at least one poultry building were ammonia, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide, trimethyl amine, styrene, toluene, xylene and methyl ethyl ketone whereas other 12 odorous compounds were not detected in poultry buildings. Generally there was no consistent concentration distribution of odorous compounds between poultry building applied with forced ventilation and poultry building applied with natural ventilation. It was found, however, that there was considerable concentration difference among odorous compounds. In monthly distribution of odorous compounds, their concentrations in September and October when ventilation rate in pig building decreased relatively were generally higher than those in July and August when ventilation rate in pig building is relatively high. On the contrary, emission factors of odorous compounds, in terms of ammonia and hydrogen sulfide, in poultry building were relatively higher in July and August than September and October. The limit of this study is that unexpected conditions such as clearance of poultry building, poultry shipment and disorder of air pump were not controlled intentionally on the on-site investigation days.
