    Abstract:
    Using two types of personal monitors for suspended particulate matter of diameter under 10 microm (PM-10) and for particles of diameter under 1 microm with attached polycyclic aromatic hydrocarbons (PPAH), we measured the PM-10 and PPAH concentrations in the indoor and outdoor air in various locations in the Tokyo area. The major findings were as follows. (1) The PPAH concentrations in a clean living room increased rapidly within several minutes after one cigarette was smoked. (2) Using the average indoor concentrations of PM-10 and PPAH in a department store as control concentrations, respectively, where the average indoor PM-10 concentration was closest to an annual average outdoor concentration in Japan, the mean value for indoor air concentrations of PM-10 by location ranged from 2.2 to 6.2 times the control concentration, and the mean value for indoor air concentrations of PPAH by location ranged from 1.0 to 32.2 times the control concentration. (3) Using the same control concentrations, the mean value of outdoor concentrations of PM-10 by location ranged from 1.6 to 8.5 times the control concentration, while the mean value of outdoor concentrations of PPAH by location were up to 353.7 times the control concentration. The major polluted places were main traffic roads, highways, and street tunnels. (4) The correlation coefficient between the PM and the PPAH concentrations in the total monitoring time was 0.014, which was not significant (P>0.05).
