  1. Air Quality Surveillance Branch • Air Monitoring Operations • Manual and Non-criteria Samplers • Reggie Smith • Special Purpose Monitoring & Data Support Section California Environmental Protection Agency Air Resources Board

  2. Ambient Air Monitoring Programs (cont.) • Particulate Matter • Toxic Air Contaminants • Hydrocarbon Compounds • Acid Deposition

  3. Types of Instruments • Manual Samplers • Time averaged data • Sampling Media • Filter samples • Cartridges • Canisters • Analyzed in separate step • Continuous Samplers • Instrumental methods • On-line data

  4. Particulate Monitoring • Particulate Matter • < 10 micrometers and < 2.5 micrometers • Size Fractional Particulate Matter • 0- 2.5 and 2.5 - 10 microns • Total Suspended Particulate • Continuous Particulate Sampler • Coefficient of Haze • Relative Visibility

  5. Particulate Standards Federal State PM2.5 65 ug/m3 15 ug/m3 24 hr Annual PM10 24 hr Annual 150 ug/m3 50 ug/m3 50 ug/m3 30 ug/m3

  6. HighVolume Sampler w/Size Selective Inlet

  7. PM10 Filter Handling Procedure • Filters are weighed pre and post sampling • Filters are inspected for tears, pinholes, frayed edges, clumps of fibers, discoloration

  8. Fine Particulate Matter - PM2.5 • 1997, U.S. EPA promulgates new fine particulate standards • ARB implementing new PM2.5 monitoring network • Samplers • Andersen Sequential and R&P Single Channel • Sampling Media • 47 mm teflon filters
