Proximity of public elementary schools to major roads in Canadian urban areas  (33 page pdf, Ofer Amram, Rebecca Abernethy, Michael Brauer, Hugh Davies and Ryan W Allen, International Journal of Health Geographics, Dec. 21, 2011)

Also discussed here: School location a factor in student health, performance (Public Affairs, Simon Fraser University, Jan. 4, 2012)

And here: School location may impact kids’ health (The Canadian Press, Jan 5, 2012)

Today, we focus on the proximity of schools are to major roads and why this constitutes a health risk to the school children. Nitrogen dioxide concentrations measured near schools  drop off significantly within 75 m and up to 200 m from the roads. . The research reviewed indicates that in the 10 cities analysed (making up 1/3 of Canada’s population), 16 % of schools are within 75 m and  36% within 200 m of traffic.  Provincial authorities in BC recommend keeping schools at least 150 m away from roads. Action may be taken with existing schools close to roads to reduce hazardous concentrations by as installing high efficiency particulate air (HEPA) filters in ventilation systems and other measures.
