| Research Abstract |
We have developed an analytical method for halogenated polycyclic aromatic hydrocarbons (PAH-X) by GC/MS with Negative Chemical Ionization method. Sensitivity of 6-chloro-benzo[a]pyrene can be 1,000 times higher than that by GC/MS with Electron Impact ionization method. This method can be used for quantifying phenanthrene and anthracene individually, even if these 2 compounds cannot be separated by GC/MS. We have analyzed PAH-X in the exhaust gas from incinerator, and the results show that PAH-X containing more than 6 halogen molecules cannot be detected. The more halogen molecules PAH-X have, the lower concentration it was. The large amount of hydrogen chloride was emitted from burning of halogenated plastics in an electric furnace, and a little PAH-X can be generated. The results in this study suggest that PAH-X generated both from cyclization of polychloroalkane and halogenation after cyclization of PAH at high temperature.
