中文摘要:

      链氯化石蜡(short chain chlorinated paraffins, SCPPs)是一类结构复杂的混合物, 在工业生产中用途广泛, 主要用作金属加工润滑剂、PVC增塑剂、高分子材料阻燃剂、油漆、密封剂、粘合剂等。本文对短链氯化石蜡的毒性效应和环境污染现状进行了综述。研究了SCCPs对于哺乳动物、鱼类和两栖类、鸟类的毒理学效应, 指出了毒理学领域存在的问题及研究需求。文章还对SCCPs作为持久性有机污染物的特性(持久性、生物蓄积性及长距离迁移性)以及SCCPs在环境介质(水、土壤和底泥、大气、食品)中的污染状况和检测技术进行了阐述。并总结了SCCPs研究中存在的问题, 指出SCCPs的检测方法仍然是环境中SCCPs研究存在的突出问题。

英文摘要:

      Short chain chlorinated paraffins (SCPPs) is a class of complex mixtures, which is widely used in industrial production, such as metal processing lubricants, PVC increase plasticizer, flame retardant polymeric materials agent, paint, sealants, adhesives and so on. In this paper, the toxic effect of SCPPs and its environmental pollution were summarized. The toxicological effects of SCCPs on mammals, fish, amphibians and birds were studied. As a class of persistent organic pollutants, the article also described the characteristics of persistence, bioaccumulation and long distance migration for SCCPs and its pollution in environmental media (water, soil and sediment, air, food) as well as its detection method. At last, we summarized the existing problems in SCCPs research, and pointed out that the detection method of SCCPs was still a prominent problem.
