  1. An Overview of Environment Canada’s Systematic PM Measurement Programs • Maris Lusis • Air Quality research Branch • Meteorological Service of Canada • EMEP Workshop on PM • April 20-23, 2004

  2. CORE Network Objectives • to provide long-term, high quality observations of atmospheric composition and radiation at locations representative of major atmospheric regimes (and geopolitical regions) across Canada • to serve as a national facility which maintains standards, provides expertise, serves as a reference network for monitoring and research studies of other jurisdictions and universities, and fulfils international monitoring commitments.

  3. Alert CORE Network [Eureka] Bratt’s Lake Kejimkujik St. Anicet Saturna Island CARE

  4. Current measurements at CORE sites CAPMoN filter pack (all sites but Alert) • 24 hour integrated filter samples (teflon, nylon, impregnated) • Analysed in lab for SO2, HNO3, and particulate chemistry (SO4, NO3,NH4…)

  5. Current measurements at CORE sites PM 2.5 and PM10 mass R&P Partisol Dichotomous Sequential Sampler Model 2025-D (all sites but Alert)

  6. Current measurements at CORE sites • PM speciation (all sites but Alert) • R&P Partisol Model 2300 Speciation Sampler with • Chemcomb Cartridges • Ions in PM2.5 (SO4, NO3, NH4….) • Elemental and organic carbon in PM 2.5 • Associated gases, measured by denuder (SO2, HNO3, NH3)

  7. Current measurements at CORE sites Aerosol optical depth (part of AEROCAN network) (Saturna, Bratt’s Lake, CARE, Kejimkujik) CIMEL sunphotometer

  8. Alert PM measurements -Canadian Baseline & Northern Contaminants Programs, & SEARCH • PM constituents (hivol) • Ions • Trace metals • POPs (88 PCB Congeners,46 Organochlorines,20 PAHs) • Black carbon (aethelometer & PSAP) • CPC • Multiwavelngth nephelometer • Impactor (to be installed in August)

  9. Chemical Species

  10. Alert: Sulphates in PM

  11. Seasonality in the black carbon measurements at Alert, 1989-2002.

  12. Temperature Trend Seasonal Cycle PCB 31

  13. CAPMoN sites were selected to be regionally representative. data is currently used for transboundary transport analyses, source-receptor relationship determination, model development and evaluation. data is used for determination of background pollution levels and long term regional and continental trends. CWS support (determination of transboundary and background influence).

  14. SO2 and SO4= Concentration Trends CAPMoN

  15. IADN suite of chemicals in PM (measured using hivols): (PCBs) Polycyclic aromatic compounds (Organochlorine pesticides) Trace Metals

  16. Enhancement of aerosol measurements at 4 existing sites – see next slide Alert samples the Arctic Haze in the winter-spring due to transport from Eurasia. In the summertime, Alert samples the NH background aerosol. Whistler samples free tropospheric aerosol entering Canada, and Asian dust and pollution transported across the Pacific Fraserdale samples downwind of the Boreal forest, providing information on secondary particles from forest VOCs and primary particles from forest fires Egbert samples aerosols in an agricultural setting, is downwind of both natural and industrial source areas

  17. Measurements/Instrumentation Routine • PILS • Organic Carbon • Light Absorption • Light Scattering • Size Distribution Special • AMS

  18. NAPS: PM2.5 Instruments in Canada (2004) • R&P TEOM Instrument (125) • Met-One BAM Instrument (37) • R&P Partisol Samplers family (35) • 2025-D sequential dichotomous sampler • 2000 single filter sampler • 2025 sequential sampler • 2300 speciation sampler

  19. NAPS: PM2.5 Monitoring Sites in Canada (2003)

  20. Partisol 2025-D Dichotomous Samplers in Canada - 2004 Existing Sites (20) Future Sites (4) Yellowknife Edmonton Elk Island Flin Flon Sydney Vancouver Saint-John Québec City Halifax Calgary Mtl-RDP St-Andrews Saskatoon Ottawa Mtl-Ontario Victoria Mtl-Chateuneuf Winnipeg Pt-Petre Wallaceburg Tor-Judson Simcoe Windsor

  21. NAPS: PM2.5 Chemical Speciation Program • Started in January 2003 • Instruments Used: • R&P Partisol 2300 Speciation PM 2.5 Sampler • Mass, nitrate, sulphate, ions, OC/EC, NH3 Collected on 3 cartidges • R&P Partisol 2025-D Sequential Dichotomous Sampler • Mass, metals, ions

  22. PM2.5 Chemical Speciation Network Existing Sites (6) Future Sites (7) Edmonton Burnaby Golden Saint-John Québec City St-Andrews Montréal Abbotsford St-Anicet Toronto-Gage Wallaceburg Simcoe Winsdor
