摘要

摘要:
近年来，环境问题一直都是社会关注的热点，如大气、土壤和沉积物中的重金属污染问题已成为社会关注的热点。要解决环境重金属污染，关键是要确定其污染源和污染途径，本研究选取了3种典型的污染，即河流污染、冶炼厂地污染及大气颗粒物污染，选择同位素示踪技术作为研究方法，并且以铜作为示踪指标，对铜元素的基本性质，以及铜同位素在地球化学过程中的分馏，不同类型样品的处理、消解以及同位素分离纯化方法，同位素测试技术、示踪技术、端元模型进行了汇总，以及对现已发表的成果中上述3种典型重金属污染的端元(自然输入源和人为输入源)，受污染途径、污染程度的研究进行了概括和总结。Cu同位素在环境污染溯源方面尚处于起步阶段，因此还需要进一步研究表生过程中Cu同位素的分馏机理，为认识重金属污染源与汇迁移过程中的机理提供重要的信息。未来的研究中，可进一步运用多种同位素相结合的方法，扩展多元同位素指纹数据库；而且同位素模型是对重金属污染源及污染贡献率进行正确评价的重要研究内容，还需构建新的多同位素多元污染模型来解决更为复杂的污染源。

Abstract:
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.
