Highly sensitive analysis, exposure assessment and emission mechanisms of halogenated organic compounds.

我们开发了包括卤代多环芳烃(XPAHs)在内的卤化有机化合物的高灵敏度分析方法。该方法包括热解吸法和负化学电离GC/MS法，并建立了这些化合物的暴露评估方法。为了研究这些化合物的排放机理，将卤化塑料在电炉中燃烧，并对产物进行了分析。其中一些化合物在氯化前发生环化反应，另一些化合物在氯化反应后发生环化反应。

We have developed highly sensitive analytical methods for halogenated organic compounds including halogenated polycyclic aromatic hydrocarbons (XPAHs). The method includes thermal desorption technique and a negative chemical ionization GC/MS method.The exposure assessment method for these compounds has been also developed. To study emission mechanisms of these compounds, halogenated plastics were combusted in electric furnace, and the products were analyzed. Cyclization was occurred before chlorination in some of these compounds, and it was occurred after chlorination in another compounds.
