| Outline of Final Research Achievements |
The purpose of this study is to reveal the environmental behaviors of high-chlorinated polycyclic aromatic hydrocarbons (ClPAHs). To achieve the purpose we first synthesized the ClPAHs with more than 3 chlorine atom to use as standards, resulted that four species of ClPAHs were newly obtained. Next we investigated the concentrations of ClPAHs in the environment, and evaluated the possible emission sources. Surveying ClPAHs in ambient particles, 24 species of ClPAHs were detected in the samples. Also, the concentrations of metals, hopanes that are typical indicators of combustion sources were also investigated in the air samples. The relationships of concentrations between ClPAHs and certain indicators showed the significant correlations, suggested that ClPAHs in the air are produced by anthropogenic sources such as industrial activities and traffic. Furthermore the photodecay tests of ClPAHs showed that a part of PAHs become stable with increasing the number of chlorine substituted.
