Enhancing Ambient Air Monitoring through Technology Integration

This project focuses on integrating advanced measurement technologies for ambient air monitoring, driven by limited funds and manpower. An internal team was formed to explore options, leading to partnerships with experts in X-Ray Fluorescence (XRF) and Beta Attenuation Monitors (BAM). The collaboration aims to develop innovative solutions, such as a semi-continuous multi-metals system for fence-line applications, utilizing cutting-edge techniques for lower detection levels of pollutants. This initiative represents a strategic approach to improve air quality monitoring and ensure effective environmental compliance.

  1. Ambient and SourceTechnologyIntegration Dennis K. Mikel EPA-OAQPS-AQAD

  2. Concept • Why initiate technology integration? • Limited Funds • Limited Manpower • Time and effort

  3. Task #1 Team Building • We formed an internal team • Ambient Air Monitoring Group • Measurement Technology Group • We looked at different technologies • Chose one we felt we could have success

  4. Task #2 Initiate technology integration project • We contacted: • Cooper Environmental – X-Ray Fluorescence (XRF) Experts • Met One Instruments – Beta Attenuation Monitors (BAM) Technology • California Air Resources Board - Operate Met One BAMs • We created a partnership!

  5. Technology Integration Cooper XRF Technology Met One EBAM Met One Mylar backed Tape – Teflon Coated

  7. Long Term Plan • Development of the semi-continuous multi-metals for fence-line and ambient applications • Lowering Detection Levels for formaldehyde and 1,3 BD using Cascade Lasers – ORD development • Pneumatic Focusing Gas Chromatography

  8. Multi-metals Fence-line – Ambient Applications • The Xact Ambient Air Toxics Monitor (Xact AATM) measures the ambient concentration of metals • Based on uses X-ray fluorescence • Sampling times for this instrument range from one to four hours. • The Xact AATM measures metals in the pg/m³ concentration range.

  9. MID-IR Cascade Laser System • Uses Tunable Infrared Laser Differential Absorption • Continuous automated operation • Detection Limit (pptv) • Formaldehyde 60 Butadiene 80 • Acrolein 120

  10. Pneumatic Focusing Gas Chromatography (PFGC) • Air sample compressed • and injected directly on column in a specially designed GC • GC is constructed within a fully functional personal computer • FID-VOC sensitivity of 50 ppt

  11. Technology IntegrationToolbox Research SBIR Collaborate with Vendors and S/L/T ORD An Intelligent Approach to Technology Integration!!!
