Today we review research on traffic related air pollution in Vancouver that examines how proximity to that traffic is linked to deaths from heart disease (CHD). Results indicate that those who are within 50 m of highways have approximately 50% greater relative risk (RR) compared to those who are not exposed to traffic. This drops to 20 to 40 % greater risk for those more than 150 m from a highway or within 50 m of a major road. The author notes that proximity to roads is only a proxy for estimating traffic volume and air pollution concentration near roads and that traffic noise is another factor that affect CHDs as well as air pollution.
