  1. Air Pollution in Hamilton – Health Effects and Sources, Some SurprisesGTA Clean Air CouncilOctober 27, 2006

  2. Performed by RotekEnvironmental And D. Corr, Ph.D. Dept of Engineering Physics McMaster University For Clean Air Hamilton /City of Hamilton/ /MOE/EC

  3. Clean Air Hamilton Strategy Risk Management Approach Applied to Community Wide Actions • Identify Problem • Measure/Evaluate • Prioritize Risks • Inform Community • Cooperative Actions www.cleanair.hamilton.ca

  4. Good Intentions+Good Science+Good Process=Real Progress

  5. The Problem Health Impacts of Air Pollutants in Hamilton Sahsuvaroglu & Jerrett 2003

  6. Health Impacts in Hamilton – by Air Pollutant Sahsuvaroglu & Jerrett 2003

  7. Study Objectives“Where is it coming from?” • Identify and rank sources, including transportation sources, of NOx, SO2, Airborne Particles and CO, using mobile monitoring techniques (no direct local sources of Ozone). • Investigate the effect of idling vehicles at a designated school during student drop off and pickup times. • Investigate trackout/road dust issues

  8. Table 1 - PM10 Point Sources 56 Sources Total

  9. Table 1 - PM10 Point Sources (contd)

  10. Table 2 - CO Point Sources 14 Sources Total

  11. Table 3 - NOx Point Sources 13 Sources Total

  12. Table 4 - SO2 Point Sources 9 Sources Total

  13. National Pollutant Release Inventory – Hamilton Point Sources • PM10 56 Sources • CO 14 Sources • NOx 13 Sources • SO2 9 Sources

  14. Total Point Source Emissions by Contaminant Tonnes

  15. Modifiers Emission - Dispersion - Accumulation - Removal

  16. What We’d Expect to See • Carbon Monoxide – 66% Transportation, 23% Industry • Sulphur Dioxide – 92% Industry, 5% Transportation • Nitrogen Oxides – 57% Transportation, 37% Industry • PM10 – 73% Open Sources/Road Dust, 18% Industry Note: MOE identified trackout/road dust resuspension as a major problem

  17. Emission Sources by Regions in Hamilton Flamborough/Waterdown NE Ind Stny Crk East Mtn

  18. Toronto National Pollutant Release Inventory (NPRI) Source Locations - Smog

  19. Mississauga National Pollutant Release Inventory (NPRI) Source Locations - Smog

  20. Halton National Pollutant Release Inventory (NPRI) Source Locations - Smog

  21. Mobile Command Centre

  22. City/Traffic Monitoring • City Wide Sampling • Road Dust/Road Impacts • Intersection Impacts • Arterial Road Impact/ Burlington St. • Cycle Routes/ Anti Idling

  23. Sampling Track, CityWide Scan

  24. City Wide Sampling

  25. NO ppb Wind

  26. Wind

  27. City Wide Sampling, Residential Locations

  28. Roads vs Residential Areas

  29. Stoplight Idling – Concentrations Downwind

  30. Burlington St. Upwind Downwind

  31. Burlington St Contribution (Approx. 600 Trucks/Hr)

  32. CARS

  33. Vehicle Idling outside Schools“Natural Experiment”

  34. Natural Experiment ppb

  35. Morning – Idling Vehicles

  36. Monitoring Vehicle at School

  37. Afternoon – Vehicle Engines Off

  38. Natural Experiment ppb

  39. Trackout/Diesel Trucks • PM2.5, PM1 Components • Photos • Sample Trace • Consolidated PM10 Data • Comparison Previous Data

  40. Road Dust , Covariance 20xPM1, 10xPM2.5, PM10

  41. Trackout 13 Jan

  42. Road Dust/Trackout 18 Locations Monitored, 14 Sources Identified

  43. PM10 ROAD DUST Ben Garden, Savas Kanaroglou, Pat DeLuca, Spatial analysis Unit, McMaster University

  44. Source Tracking • Photos • SO2 Tracing • Other Contaminants • SO2 Data Consolidation • Source Ranking/NPRI Comparison, SO2, NO, PM10
