Is there a Low-Cost Monitor to Measure Roadside Urban Emissions in Real-Time?


A Novel Method for Reliable Long-term Assessment of Exposure to Traffic-related Air Pollution Mixtures(Abstract, Natalia Mykhaylova, Kelly Sabaliauskas, Jon M Wang, Ezzat Jaroudi, Cheol-Heon Jeong, Jeff Brook, Greg J. Evans, American Association for Aerosol Research 32nd Annual Conference, Sep. 30-Oct.4, 2013)

Today we look at a low-cost air quality monitor, developed at the University of Toronto, with the aim “to encourage local governments to deploy commercial versions of these low-cost devices in large numbers around urban areas as a way of generating a much more nuanced and up-to-the-minute picture of the invisible geography of pollution”. This is part of a larger research project aimed at assessing the health risks of roadside air pollution in Canada’s largest city where more than 2,000 people die prematurely each year according to the Illness Costs of Air Pollution (ICAP) model developed by the Ontario Medical Association and widely recognized by established authorities (such as the Auditor General of Canada and the Commissioner for the Environment  for Ontario). The sensors provide a required precision of 5 to 15 ppb for O3 and NO2, 20 microgm/m3 for PM 2.5 and the entire cost of the unit is expected to be under $300.
