| Outline of Final Research Achievements |
The main purpose in this study was to reveal products and formation mechanisms of hgalogenated polycyclic aromatic hydrocarbons (PAHs) by photochemical reactions in coastal environments. The experimental results showed that chlorinated derivatives can be formed under environmental relevant conditions of coastal area compared to brominated derivatives. The role of dissolved organic matter (DOM) in the photochemical reaction and halogenation processes were also studied. The DOM (humic acid) has both inhibition and promotion effects in the secondary formation of PAHs. In addition, the halogenation of PAHs were promoted on kaolinite particles than monmolironite particle and glass beads.
