  8. Sampling Procedures & Methods • 4-5 hr sampling events week prior to broiler and roaster movement • 2002 = 10 days; 2003 = 9 days (summer flocks) • Total dust: gravimetric using 37mm cassettes and pumps calibrated at 2 L/min. (NIOSH # 0500) • Ammonia: Gastec dosimeter tubes # 3DL (10 ppm) and Impinger method (OSHA ID-164) • H2SO4 :10L tedlar bags sent to ISU (Jerome 631 H2SO4 Analyzer) • Odor: 10L tedlar bags sent to ISU (AC’Scent International Standard Olfactometer)

  9. Sampling Procedure: • 2 locations opposite tunnel fans (front and rear) • ~5 hrs/day, one week prior to broiler & roaster movement • # Sampling events during summer flocks: 10 days in 2002; 9 days in 2003 Front Rear 4’
