Abstract: 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.
