I found that micro fiber seat (MFS) were stable trapped airborne particle, polycyclic aromatic hydrocarbons (PAHs) and metals as Mg, Al, Ca, Mn, V. When assuming an index of ΣPAHs (6 chemicals with unit risk for WHO) concentration, it was suggested that MFS trapped PAHs in living areas. And ΣPAHs concentration with MFS were suggested an environmental index of PAHs concentration in PM2.5 as ΣPAHs. In addition, airborne PAHs risk in living areas was estimated by interpolating the unmeasurement area using GIS and it was able to visualize. As a result, it was found that there were the high risks at the roadside area.
