An objectives of this study is to investigate indoor concentrations of 22 odorous compounds, which are regulated by the domestic act, emitted from pig buildings through on-site visit per month from July, 2011 to June, 2012. Of 22 odorous compounds, the highest concentration was found in ammonia with ppm unit, followed by hydrogen sulfide, methyl ethyl ketone, propionic acid and butylic acid with ppb unit of approximate hundred level. The other odorous compounds were detected below ppb unit of approximate ten level. A remarkable finding is that there is no pig building which showed the airborne levels of five aldehyde-based odorous compounds (acetaldehyde, propionaldehyde, butyraldehyde, n-valeraldehyde and i-valeraldehyde). In general, indoor concentrations of odorous compounds in pig buildings were higher in scraper type than slurry type based on pig manure collection system and higher in enclosed type than winch-curtain type based on ventilation mode, respectively. In temporal distribution of odorous compounds, their concentrations in summer season (June to August) when ventilation rate in pig building decreased relatively were generally higher than those in winter season (December to February) when ventilation rate in pig building is relatively high. The seasons of spring (March to May) and autumn (September to November) showed middle levels of odorous compounds between summer and winter.
