| 摘 要： | 由于稳定同位素在特定污染源中组成确定,且具有分析结果精确可靠、在污染物迁移与转化过程中不发生显著变化的特点,故已被广泛应用于环境污染事件的仲裁、环境污染物的来源分析与示踪研究中。介绍了稳定同位素分馏对于来源分析的影响以及稳定同位素技术在污染物溯源与示踪中识别大气多环芳烃来源、推测环境中硫和铅的来源、考察甲基叔丁基醚来源与降解过程等方面的应用进展。

| Abstract: | The stable isotope composition was characteristic in the pollution source.And it was relatively fixed in the process of pollutants transference and transformation.At present the precise analysis result of stable isotope ratio could be got easily.So the stable isotope could be applied to the pollution affair arbitration,source apportioning and trail pollutants.The researchful status of the isotope fractionation the stable isotopes in tracing to sources and trailing pollutant,specially in apportioning the atmospheric PAHs sources,appraising the origins of S and Pb and investigating the sources and attenuation of MTBE,was reviewed. |

| Keywords: | stable isotope isotope fractionation source apportionment trail pollutant |
