  2. PAHs Benzo(a)Pyrene

  3. Higher Concentrationsof These Metals

  4. Average values (g/m3) Sulphur Dioxide Sulphate Bearspaw 5.81 0.99 Priddis (Non- Flaring) 0.74 0.38 Priddis (Flaring) 1.83 0.52 Kananaskis 0.097 0.047 Calgary 1.3 - Houston 2.47 - Alberta Environment Ambient Air Quality (annual) 30 - SO2 and SO42- Concentrations

  5. SO2Modelling

  6. Vegetation • Both Priddis and Bearspaw are significantly affected by SO2 pollution relative to the control as determined by Si/So ratios • Bearspaw is the most affected by sour gas emissions according to isotope data • Priddis is more affected by environmental stresses as indicated by histochemical analysis and visual damage

  7. Precipitation

  8. Precipitation • Rural sites had higher deposition of sulphate. • Nitrate does not vary with the degree of urbanisation. • Sulphate at Carsland primarily derived from industrial emissions. • Sulphate flux greatest in SE Calgary.

  9. N-Alkanes • No significant difference between flaring and non flaring events may indicate that: • particulate n-alkanes transform into more complex molecules • Or particulate n-alkanes were fully combusted in the flare

  10. Indoor Particulates - CPM4

  11. Indoor VOC Concentrations

  12. Perceived Health Effects • In general, Priddis residents show a greater concern and take more action towards the sour gas issue • Significant correlation - Priddis & Bearspaw: level of concern  level of importance - Bearspaw:  level of concern  perceived health impacts

  13. Media and Public Perception

  14. LEGAL ISSUESReport of the Provincial Advisory Committee Advisory Committee • Representative cross section of affected interest groups • Critical in approach • Outlines a plan of implementation • EUB compliance critical Recommendations • Restructuring of the hearing process • Improved industry and public interaction • Better enforcement and more audits • Public education on sour gas issues

  15. Acknowledgements • We would like to thank the following people and organisations: • Butterfield Acres, Rothney Astronomical Observatory, K. McDonald, K. Foster, • Van Ho, Matt Tammam, John Tong, G. Kerlukes, T. Lambert, A. Lucas, S. Roth, and the ENSC faculty and staff.
