| Research Abstract |
In the present study, we focused the halogenated polycyclic aromatic hydrocarbons (halogenated PAHs) that is one of non-regulated pollutants, and investigated the occurrences in the environment and the biological effects. The surveys of chlorinated PAHs (ClPAHs) ambient air in 14 sites in Japan, 1 site in Korea and 1 site in China showed that ClPAHs is universally present in the air since some of that were detected from all air samples. In addition, the surveys of ClPAHs in Asian sediments also showed the universalistic pollution. The biological effects were investigated by oral administration of ClPAH in rat, resulting that chlorination of PAH could enhance significantly induction of specific drug-metabolizing enzyme.
