全氟辛烷磺酸、全氟辛酸及其盐类检验技术的研究进展

Study on Testing of Perfluoroocatane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in Packaging Material for Food

摘要:

全氟辛烷磺酸（PFOS）、全氟辛酸（PFOA）及其盐类物质具有生殖毒性、诱变毒性和发育毒性等多种毒性，也是目前最难降解的持久性有机污染物。全氟化合物独特的拒水拒油性,使其被广泛地应用于纺织、皮革、造纸等行业。PFOS和PFOA及其盐类物质通过食品包装材料，已经不知不觉进入我们的食品中，影响了食品安全，威胁着人们的身体健康。其分析检测技术和方法的相关研究也得到日益广泛的关注和重视。本文讨论了PFOS和PFOA及相关盐类的概况及其检测技术的研究进展,并对当前各类检测技术存在的问题作了探讨。

Abstract:

Perfluoroocatane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have reproductive, mutagenic and developmental toxicity, which are persistent organic pollutants and the most difficult to be degraded. These compounds show both oil and water repellence properties, thus being widely used in textile, leather, paper, etc. It was also found that PFOS and PFOA have unwittingly gotten into our food chain through food packaging materials, threatening food safety and public health. In this reviewed, the characteristics and detection technology of PFOS and PFOA were discussed.
