  1. CARPA SUMMIT 2008DATAMonitoring, Sampling, and Lab Techniques Paul A. Nony, Ph.D Center for Toxicology and Environmental Health, LLC

  2. Equipment and Capabilities: What Works • Air monitoring equipment • Air sampling equipment • Laboratory Techniques/Considerations

  3. Air Monitoring Equipment • RAE Systems instruments • MultiRAE • AreaRAE • ppbRAE • UltraRAE • MiniRAE • EntryRAE • Sensors • Photoionization Detector (PID) • Non-specific detection of volatile organic compounds • Electrochemical sensors • NO/NO2,Cl2, H2S, NH3, HCl, HF, HCN, SO2, CO • O2 • LEL

  4. Photoionization Detector (PID)

  5. TVA 1000B (PID/FID)

  6. Air Monitoring Equipment • Colorimetric Detector Tubes (Gastec) • Provide chemical-specific results for a wide range of chemicals. • CTEH keeps most tubes in stock

  7. Air Monitoring Equipment • Single Point Monitors • Used for acids and isocyanates

  8. Air Monitoring Equipment • Optical Aerosol/PM Monitors (TSI) • Various cutoffs for particle size • New Dusttrak measures both size and mass simultaneously

  9. Considerations for Monitoring Locales • Breathing zone • In and around work areas and workers • Away from exhaust sources • Indicator approach • Community coverage • Upwind and downwind • Special receptors

  10. Characterization of Unknowns • Hazmat ID • Portable infrared spectrophotometer • Enclosed in a Pelican case; can be decontaminated in the field • Library of over 25,000 spectra • Liquid or solid unknowns

  11. Smiths HazMatID

  12. Characterization of Unknowns • Hapsite Portable GC/MS • Unknown Identification • Very low detection limits (ppt) • EPA approved methods

  13. Inficon HAPSITE Portable GC/MS Headspace Analysis System Smart Plus Chemical ID System SituProbe Purge and Trap System

  14. Characterization of Unknowns • Miran SapphIRe™ IR Spectrophotometer

  15. Mercury Vapor Detectors Ohio Lumex Mercury Vapor Analyzer Jerome Mercury Vapor Analyzer

  16. Air Sampling Equipment MiniCansTM SUMMA Canisters

  17. Air Sampling Equipment • Analytical Sampling Pumps- SKC • CTEH stocks most available SKC sampling media

  18. Considerations for Sample Placement • Breathing zone • Between source and receptors • Complete 360-degree perimeter • Locations where people are (especially surface samples)

  19. Meteorological Data • WeatherPak 2000

  20. Lab Techniques/Considerations • Many chemical-specific analyses • Volatile organics – EPA TO-15 + TICs • Metals • PAHs • Total particulate matter • Aldehydes • Dioxins/furans • Special analyses

  21. Lab Techniques/Considerations • Field QA/QC • COC • Proper set up of sample apparatus (filters/media) • Collect blanks/background samples • Proper sample labeling and documentation • Lab QA/QC • Certified clean canisters • Lab certifications (AIHA, NELAP, etc.) • SOPs, QAMs • Turnaround time/throughput • Usable deliverables • Method selection fits data requirements
