摘要
根据Pb同位素的地球化学特点 ,分析了Pb同位素在示踪环境污染中的理论基础。从国内外大量研究实例出发 ,总结了近年来Pb同位素在示踪工业Pb污染的应用现状 ,肯定了Pb同位素在示踪Pb工业污染中的地位和作用。结合我国首次北极考察海洋大气气溶胶铅稳定同位素的初步研究 ,笔者认为研究环境系统有关对象 (如大气、海水、冰雪和沉积物等 )的Pb同位素组成 ,通过其Pb同位素混合模型计算和源区参数计算 ,可有效示踪Pb工业污染的来源。
Based on the geochemical characteristic of lead isotope,the theory base of lead isotope for environmental pollution tracing is analyzed.From lots of study examples,we summarized current application status of lead isotope trace for industrial pollution and affirmed the role and function of lead isotope trace for industrial pollution.According to the elementary lead isotope study of Arctic aerosol,we propose that the source,distribution and long\|range transmission of the industrial pollution of lead could be effectively traced on the basis of simulation of lead isotopic mixing model and parameters of lead source and by studying the lead isotopic composition for environmental system object,such as sea water,ice\|snow,rain water and sediment,etc.
