摘要:

氯代多环芳烃(chlorinated polycyclic aromatic hydrocarbons,Cl-PAHs)作为多环芳烃的氯代衍生物,具有类似二恶英的致癌、致突变毒性,并在环境中广泛存在.利用结构-活性关系及逸度模型对该新型有机污染物进行性质及环境归趋的预测.结果表明,随着氯原子取代数的增加,Cl-PAHs的毒性会有所增强,且在环境中更趋向富集于土壤和底泥中,具有与二恶英类似的环境行为.

Abstract:

Chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs) are chlorinated derivatives of PAHs, and some ClPAHs have been shown to elicit dioxin-like toxicity and mutagenic properties. Nevertheless, information of the physical/chemical properties and environmental fate of Cl-PAHs are limited. Quantitative structure-activity relationship (QSAR) and level Ⅲ fugacity model were used to estimate the physical/chemical properties and environmental fate of 20 Cl-PAH congeners in this study. The result shows that the toxicity of Cl-PAHs increases with the increasing of chlorination level. These new type of pollutants tends to accumulate in soil and sediment with dioxin-like fate in the environment.

Key words: quantitative structure-activity relationship(QSAR); fugacity model; chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs); environmental fate
