Progress of copper isotope and its application in environmental pollution tracing

In recent years, environmental problems have been a hot topic of social concern, such as heavy metal pollution in the atmosphere, soil and sediment, which are closely related to our life.To solve the heavy metal pollution in environment, the key is to determine the source of pollution.With the rapid development of stable isotope tracer technology, further achievements have been made in the study of the traceability of heavy metal pollution. Meanwhile, isotope tracer technology has become an important means in the traceability of heavy metal pollution.To better understand the isotope tracer technology application in environmental pollution sourcing, having the copper isotope as an example, the basic properties of copper, isotope fractionation in the geochemical process, processing and purification different types of samples, isotope analyze technique, tracer technique, the meta model has carried on the brief summary.This paper further describes the end members(natural input source and artificial input source), pollution path and pollution degreeof river pollution, smelter pollution and atmospheric particulate pollution. Finally, the application of isotope tracer is summarized and prospected.
