A 3,000 head swine production facility in central Iowa will be monitored over a one year period. Three particulate material samplers will be placed at the swine facility located either between buildings or several hundred meters north or south of the main housing units depending on wind direction. Field gas samplers containing thermal desorption sorbent tubes will be employed wherever particulate material samplers are located with one additional gas sampler stationed to monitor the gaseous exhaust from a particulate material sampler. There will be 4 to 5 sampling events conducted during the year (early fall, late fall, early spring, late spring and summer), and each event will last approximately one week in duration. In addition, grab samples using either glass or fused silica lined canisters will be taken and analyzed for speciation of reduced sulfur compounds. Particulate matter volatile organic compound profiles will be obtained by heating particulate material at elevated temperatures (90-110C) under a nitrogen gas stream and collecting the gaseous effluent onto thermal desorption tubes. These sorbent tubes will then be analyzed by GC/MS. In addition, if enough PM is collected this material will be analyzed for total C, N, and S by combustion analysis and inorganic elemental composition by inductive coupled plasma spectrometer.
