Abstract
We tried to measure and confirm the diameter of particles collected on micro fiber sheets (MFS) which provide a simple monitoring method of particular matter (PM) in the ambient air. And we investigated the potential for using MFS as an indicator of the concentration of polycyclic aromatic hydrocarbons (PAHs) and environmental risks of ∑PAHs in the atmosphere. In addition to this, we also set up MFS at a large number of sites in built-up areas and evaluated the risk of PAHs in the ambient air. The results of this indicated that the MFS were able to point out the PM, ∑PAHs and environmental risks of ∑PAHs. The results of measuring the PAH risks at multiple points showed that risks that cannot be ignored exist not only in main roadside areas but also in residential areas in regional cities.
