Estimating Health Impacts on Major Streets Using Oxidative Potential of Particulates


Contrasts in Oxidative Potential and Other PM Characteristics Collected Near Major Streets and Background Locations (32 page pdf, Hanna Boogaard, Nicole A.H. Janssen, Paul H. Fischer, Gerard P.A. Kos, Ernie P. Weijers, Flemming R. Cassee, Saskia C. van der Zee, Jeroen J. de Hartog, Bert Brunekreef, Gerard Hoek, Environ Health Perspect, Oct. 20, 2011)

Today’s review article looks at how particulates near heavy traffic on major streets generates hydroxyl radicals and how this in turn may be a better measure of health impacts than simply monitoring PM 2.5 or PM 10. The results indicate the oxidative potential near heavy traffic was 4 to 6 times greater than in suburban locations.
