  1. Quality Assured Measurements of Animal Building Emissions: Part 2. Particulate Matter Concentrations Albert Heber; Teng Lim; John Gallien, Ji-Qin Ni; Pei-Chun Tao Purdue University, West Lafayette, IN Larry Jacobson University of Minnesota, St. Paul, MN Jacek Koziel Texas A&M University, Amarillo, TX Steven Hoff Iowa State University, Ames, IA  Yuanhui Zhang University of Illinois, Urbana, IL Jerry Baughman North Carolina State University, Raleigh, NC 

  2. Objectives • Describe use of TEOM in livestock buildings to measure TSP, PM10 and PM2.5. • Discuss QAQC • Show some preliminary data collected this year

  3. Laying House PM

  4. Dust Measuring Strategies • Determine temporal variation (Hinze et al., 1998) • Semi-continuous mass monitor • Representative exhaust fan (minimum winter) • Calibrate with FRM • Determine spatial variation (Wang et al., 1999) • Multi-point gravimetric filter sampling • Multiple exhausts plus ambient • Calibrate with FRM

  5. TEOM flow schematic

  6. TEOM record in a pig house (Hinz et al., 1998)

  7. PM Monitoring Schematic

  8. Raceway Contains Vacuum Lines

  9. TEOM PM10

  10. System Calibration • Flow controller calibration (software) • Mass flow controller calibration (hardware) • Analog calibration • Mass transducer verification • Flow audit procedure • Ambient temperature calibration • Barometric pressure calibration

  11. TEOM Maintenance • Filter replacement • PM-10 inlet cleaning • Replacing large bypass in-line filter • Replacing flow controller filters • Cleaning air inlet system • Leak testing

  12. Changing TEOM Filter

  13. Loaded TEOM Filter

  14. “Feathered” Bug Screen

  15. Plugged Bug Screen

  16. PM10 Inlet Body

  17. Large Particles Collected

  18. Collocated TEOMS, FRM Wedding PM10 External screen PM10 inlet Fan inlet Cabinet

  19. Collocated PM10 Measurements24-h at laying house exhaust Anticipatory Feeding

  20. Four Collocated TEOMs in laying house exhaust (4/3/02)

  21. TSP vs. PM10 in Laying House Exhaust Air (5/2/02)

  22. Collocated PM2.5, PM10, TSP at laying house

  23. Effect of Filter Loading Humidity Effect

  24. Lagoon Tunnel-ventilated finishing houses with flushing Oil sprinkled building

  25. Oil Sprinkling

  26. Oil pressure

  27. TSP Measurements in Two Swine Barns (11/08/02)

  28. Effect of Pig Activity on TSP

  29. Nine shrouded vanes installed at laying house Open vane (cheaper) 50% variations with static pressure!

  30. UIUC test of anemometer Calibration at UIUC BESS Lab

  31. Open impeller vane anemometer

  32. Open propeller

  33. Small Vane Anemometer Readings vs. Building Static Pressure

  34. Summary • First measurements of TSP, PM10 and PM2.5 in livestock buildings in U.S. have been conducted. • QAQC is critical to TEOM success. • Moisture is adsorbed and desorbed • Oil sprinkling reduces PM • Real-time concentrations correlated to animal activity • Anemometers provide real-time airflow data.
