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
The Problem Health Impacts of Air Pollutants in Hamilton Sahsuvaroglu & Jerrett 2003
Health Impacts in Hamilton – by Air Pollutant Sahsuvaroglu & Jerrett 2003
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
Table 1 - PM10 Point Sources 56 Sources Total
Table 2 - CO Point Sources 14 Sources Total
Table 3 - NOx Point Sources 13 Sources Total
Table 4 - SO2 Point Sources 9 Sources Total
National Pollutant Release Inventory – Hamilton Point Sources • PM10 56 Sources • CO 14 Sources • NOx 13 Sources • SO2 9 Sources
Modifiers Emission - Dispersion - Accumulation - Removal
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
