Concentrations and emission rates of hydrogen sulfide (H2S), ammonia, (NH3), carbon dioxide (CO2), odor, and particulate matter with aerodynamic diameter of less than 10 μm (PM10) were measured in two mechanically ventilated swine farrowing rooms in Illinois from October 2003 to May 2004. This research was part of a federally funded, six-state emission measurement project entitled “Aerial Pollutant Emissions from Confinement Animal Buildings.” Gaseous and particulate contaminants were measured continuously while odor was measured periodically. Daily pollutant average concentration varied throughout the test sampling period; the respective average concentrations of NH3, H2S, CO2, odor, and PM10 were 5.5±2.3 ppm, 281±154 ppb,1320±480 ppm, 564±516 OU/m3, and 261±196 μm/m3 for room 1 and 5.6±2.5 ppm, 302±140 ppb, 1410±514 ppm, 686±630 OU/m3, and 274±162 μg/m3 for room 2. The daily mean emission rates between the two farrowing rooms did not vary significantly with NH3, H2S, CO2, and PM10 emission rates of 12.3±5.1, 1.5±0.7, 6920±3380, and 1.1±0.9 g/d per animal unit (AU), respectively for room 1 and 11.7±6.7, 1.4±0.7, 6640±3970, and 1.2±1.3 g/d-AU for room 2; the odor emission rates were 36±26 and 50±32 OU/s-AU for rooms 1 and 2, respectively. There is a general trend that the emission rates of these pollutants were higher in the summer than in the winter.
