Study of Phthalic Acid Esters in Food and Plastics rubber by GC-EI/MS and CG-MS/MS

Abstract

酞酸酯类化合物(Phthalicacidesters,简称PAEs)是塑料制品中不可缺少的一种改性添加剂。过去人们一直认为PAEs的毒性低,因而毫无限制地生产,但近年来的研究结果表明,尽管它们在环境中的残留量不大,急性毒性不明显,但具有致突变、致癌和致畸性,并可混合在食物、空气和其它物质中,通过消化、呼吸器官和皮肤进入人体,已对人体健康构成了潜在危害,故PAEs被称为“第二个全球性PCBs污染物”。 本学位论文致力于动物内脏,蔬菜以及塑料橡胶中十几种PAEs残留分析的方法研究,针对不同的样品体系,建立了以不同溶剂为提取剂的超声提取、Florisil硅土净化预分离、GC-EI/MS定性定量分析...Phthalic acid esters ( PAEs ) are widely used as plasticizers all over the world. In the past year, people had thougt that they were less toxic, but recently, more and more investigations have shown that PAEs are Environmental Incretion. Usually,they combine with the food, the air and other things, coming into body through digestion, respiration or skin and leading to the instability of internal s...学位:理学硕士院系专业:化学化工学院化学系_分析化学学号:2005130181
