The concentration change of suspended particulate matter (SPM) in indoor and outdoor air environment was studied by the use of the new personal sampler, SPMP-sampler. The sampling points are located along the main road at Tokyo metropolitan area. SPM measurements of indoor and outdoor air environment were carried out five seasons during 1986 to 1987.
The concentration of SPM in indoor air environment increased in proportion to that in outdoor air. The concentration of polycyclic aromatic hydrocarbons (PAHs) in indoor air also increased in proportion to that in outdoor air.
The content of PAHs in SPM changed depending upon its particle size. PAHs concentrated more in fine particles below 2μm than in coarse particles, 2-10μm in aerodynamic diameter. There were significant relationships between the concentration of benzo (k) fluoranthene, benzo (a) pyrene, and benzo (ghi) peryrene in air environment.
