Research Abstract |
Recently, the compounds that polycyclic aromatic hydrocarbons substituted chlorine atom, halogenated PAHs, have been found in the air, whereas there is a few information concerning environmental behaviors of halogenated PAHs. In this study, we found that halogenated PAHs are universally distributed in the environment such as air, soils and sediment. In particular, we firstly found that brominated PAHs are present in the particle phase in air. Diurnal variation analysis of halogenated PAHs indicated that halogenated PAHs in the air are susceptible to photodecay. In addition, exposure risks of ambient halogenated PAHs estimated from aryl hydrocarbon receptor binding activity were suggested to be considerably lower than those of PAHs.
