RIVM Report 723301005
PAH concentrations were measured in city areas on nine days with calm weather at three types of sites (rural backgound, city background, road with heavy traffic) were statistically analyzed. Twenty-two PAHs were examined individually to determine the utility of each as an indicator of the carcinogenic potency of a PAH mixture. Benzo[e]pyrene, chrysene and benzo[a]anthracene scored the highest, along with the current PAH indicator, benzo[a]pyrene. Furthermore, a survey on possibilities for maintaining the PAH standard with the aid of other compounds (black smoke, PM-10, CO, NOx, SO2) showed the best results with black smoke and NOx.
