摘　　要：由汽车尾气净化器的安装使用而导致环境中的铂族元素尤其是铂、钯、铑的含量逐渐增长,铂族元素对于生活和生态环境的影响也越来越多受到关注。论述了汽车三元催化剂中铂族元素毒性、铂族元素在环境和生物样品的分布、环境样品中铂族元素的消解、测定方法以及干扰处理方法,总结了多国测定结果并对结果进行了综合评述。Increasing environmental concentrations of platinum group metals （PGEs）,in particular platinum（Pt）,rhodium （Rh） and palladium （Pd）,from the catalytic converters,have been reported worldwide. The impact of these three metals on the living and ecological environment has been concerned. The toxicity of platinum group elements from the catalytic converters,the distribution of platinum group elements in the environmental and biological samples,the method of sample digestion,determination as well as the eliminating of spectrum interference of PGEs are discussed in this paper.
