Interpretive Summary: Technical Abstract: The persistence and long life expectancy of ammonia, odors and toxic pollutants from poultry houses may be due to the ability of suspended particulate matters (SPM) to serve as carriers for odorous compounds such as ammonium ions and volatile organic compounds. SPM is generated from the feed, animal manure, and the birds themselves. A large portion of odor associated with exhaust air from poultry houses is SPM that have absorbed odors from within the houses. Understanding the fate and transport processes of particulate emissions in poultry house is a necessary first step in utilizing the appropriate abatement strategies. In this study, the examination of the association of various polyatomic anions with ammonium ion in various particle sizes (inhalable fraction, PM10, and PM2.5) was carried out. Fractionated SPM (< 2.5 'm, <10.0 'm, and total inhalable fraction or TIH) were collected from broiler houses using particle trap impactors. The SPM from the particle trap impactors were extracted and analyzed for various inorganic species using ion chromatography (IC). The results showed that fractions of ammonium ions in SPM were highly correlated with sulfate, phosphate, and nitrate anions, and increased in magnitude over several successive flocks during a four-flock total cleanout cycle. The magnitude of correlation increased as the PM sizes decreased. Sulfate appeared to be highly associated with ammonium over phosphate and nitrate anions. |
