Migration of volatile organic compounds from attached garages to residences : A major exposure source

15 single-family houses with attached garages in southeast Michigan have been investigated for that study whose aim was to characterize VOC concentrations, exposures, airflows, and source apportionments.39 VOC species were detected indoors, 36 in the garage, and 20 in ambiant air. Garagz/indoor ratios and multizone IAQ models show that nearly all of the benzene and most of the fuel-related aromatics in the houses resulted from garage sources. Their conclusion are presented.
