Technical Abstract: Volatile organic compounds (VOC) associated with confined animal feeding operations (CAFO) is of regulatory interested due to the potential emissions of both ozone precursors compounds and hazardous air pollutants. Emissions of VOC from CAFO occur in both gaseous phase and sorption onto particulate matter (PM). Studies have been conducted on the gaseous emissions of VOC from CAFOs, but little is known on the levels or composition of VOCs emitted from CAFOs on PM. In this study, high volume PM 10 samplers were placed near CAFO’s, lagoons, and rural cropped field locations. Concentration of dust mass of the binder free glass fiber filter were recorded. A portion of each filter was thermally extracted in glass vessels purged with nitrogen and collected on a variety of sorbent tubes containing carbon molecular sieve, graphitized carbon, or Tenax sorbent material. Each sorbent tube was thermal desorbed and analyzed by either GC/MS or GC/MS/PFPD (pulsed flame photometric detector) analysis. Compounds were initially identified using library matching and confirmed with reference standards. Compounds identified include volatile and non-volatile fatty acids, phenolic compounds, indolic compounds, and sulfur compounds.
