SOCAAR is pleased to announce the next seminar in our 2013-2014 seminar 
series.

Near-road measurement of traffic-related pollutants

Elevated concentrations of traffic-related air pollutants can arise near major 
roadways. As a result, living and spending significant time near major roadways 
has been identified as a risk factor for a range of adverse health outcomes; the 
health of up to 10 million Canadians may be at risk. A nationwide near roadway 
monitoring study has been initiated to better understand the exposure of 
Canadians to traffic related pollution. Data from this study will also help resolve 
the amount of air pollution arising from Canada’s vehicle fleets, by evaluating 
emissions from individual vehicles and the resulting diurnal and 
weekend/weekday temporal patterns of traffic-related pollutants. In this 
seminar, the near-road monitoring network study will be introduced. Initial 
measurements of spatial gradients and temporal variations of traffic-related 
pollutants and fuel-based emission factors from individual vehicles will be 
presented.

March 5, 2014, 3 - 4 pm
Wallberg Building, 200 College Street, Room 407
