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.

本研究以非管制污染物卤代多环芳烃（halogenated polycycyclic aromatic hydrocarbons，HPAHs）为研究对象，对其在环境中的存在状况及其生物学效应进行了研究。通过对日本14个采样点、韩国1个采样点和中国1个采样点环境空气中氯代多环芳烃（ClPAHs）的调查，发现空气中普遍存在ClPAHs，所有采样点均检测到部分ClPAHs。此外，亚洲沉积物中氯多环芳烃的调查也显示了普遍性的污染。用大鼠口服法研究了氯代多环芳烃的生物学效应，结果表明，氯代多环芳烃能显著增强对特定药物代谢酶的诱导作用。
