短链氯化石蜡研究现状

Research status of short chain chlorinated paraffins

作为一种潜在的持久性有机污染物,短链氯化石蜡(Short chain chlorinated paraffins,SCCPs)近年来正在接受斯德哥尔摩公约的审查。它具有持久性、生物富集性,长距离迁移、高毒性等特点,可能会对生态环境和人体健康造成威胁,目前许多国家已经对SCCPs推出了禁令。中国生产的氯化石蜡(CPs)由于没有相关产品标准的限制,其成份多少都会含有一定SCCPs,中国每年都会消费大量的CPs,在消耗的同时会产生较大的排放量,这些排放所造成的潜在环境污染风险是不可估量的。本文通过查阅相关文献,对短链氯化石蜡研究现状进行了整理。

As a kind of potential of persistent organic pollutants (pops),Short chain chlorinated paraffins (SCCPs) is undergoing a review by Stockholm convention.It has the characteristics of persistence,biological enrichment,long-distance migration and high toxicity,which may pose a threat to the ecological environment and human health,so many countries have introduced bans on SCCPs.The chlorinated paraffin (CPs) produced in China which lack of product standards contains SCCPs.With large consumption of CPs,China produce a large amount of emissions every year.In this paper,the research status of short chain chlorinated paraffin is summarized by referring to related literatures.
