Table 5.2 compares Hamilton with other cities for ozone and PM2.5 CAAQS (particulates), finding Hamilton is around average

Huh? If we look at Table 5.2, Downtown Hamilton comes dead last of all cities in Ontario in both 24 hour PM2.5 and also in annual PM2.5. For particulates, Hamilton is not average. Hamilton is the worst.

This is of particular concern since fine particles, specifically PM2.5 and PM10, kill more people in Hamilton than all other pollutants combined. This mortality effect of fine particles may be seen on Figure 14 on page 25 of the Clean Air Hamilton report.

Although motor vehicle drivers produce 50% of all pollution in Hamilton, they produce an absolute majority of the fine particles and NOx that do most of the killing of human beings. From page 25 of the report "The majority of these health impacts were due to particulate matter (PM) and oxides of nitrogen (NOx), primarily from transportation sources."
