Title: Non-tailpipe particles: sampling, exposure models, and health effects
Abstract:
Traffic-derived air pollution comprises of a mixture of gaseous pollutants and particulate matter (PM) from exhaust (tailpipe) as well as non-exhaust (non-tailpipe) emissions. Non-tailpipe emissions mainly arise from mechanical abrasion
of brakes and tires, erosion of road surfaces and resuspension of a mixture of dust that accumulates on road surfaces. Most epidemiological and experimental research into traffic-related pollution focuses on tailpipe exposures, with far less attention paid
to non-tailpipe exposures despite the fact that it is an important source of toxic metals in urban atmospheres. We present results of the Intra-Community Variability study, a spatially intensive sampling campaign of PM concentrations at multiple size fractions
(quasi-ultrafine, accumulation mode and coarse) collected and analyzed for chemical speciation at over 220 locations across Southern California. With a focus on non-tailpipe metal tracers, we further developed spatiotemporal land use regression models to generate
exposures with which we conducted a health effects study of the association of children’s lung function.
