| Outline of Final Research Achievements |
Halogenated polycyclic aromatic hydrocarbons are potential candidates of the persistent organic pollutants in terms of their dioxin-like toxicities and environmental persistence. Our results suggest that waste incineration could be a potential source of halogenated PAHs in Japan. We elucidated the mechanism of formation of halogenated PAHs during the combustion with a developed kinetic model describing the chlorination of PAHs. Chlorinated PAHs could be unintentionally generated during cooking of fish and meats, especially during gas-grilling (direct heating). We also found that exposure to PAHs and ClPAHs in cooking exhaust gas via inhalation could be a major route of exposure to these toxic compounds; therefore, the grilling of fish indoors may pose a health risk, especially to kitchen workers.
