This paper is a case study conducted in Bursa, northwest of Turkey and describes the pollutant gases such as ammonia (NH3), hydrogen sulphide (H2S), methane (CH4), carbon dioxide (CO2) concentrations and emissions measured in winter and summer seasons from three broiler houses. In this study, pollutant gas concentrations, temperature, relative humidity and airflow rate were continuously recorded for four sequential days. The average daily mean (ADM) house concentrations of pollutant gases in winter and summer seasons were measured as 31.77 and 4.78 ppm for NH3, 19.75 and 21.32 ppb for H2S, 2.56 and 15.68 ppm for CH4, 2495 and 895 ppm for CO2, respectively. The average daily emissions of NH3, H2S, CH4, and CO2 were 442, 279, 15.88 g h-1 and 82.71 kg h-1 in winter season for all three houses while average daily emissions of NH3, H2S, CH4, and CO2 were 169 g h-1, 604 mg h-1, 557 g h-1 and 221 kg h-1 in summer season from all three houses, respectively. Emission models for all pollutant gases monitored were also developed. There was a clear diurnal pattern among pollutant gas concentrations rather than emissions at the end of the study.
