摘　　要：水环境中污染物的源辨识及污染过程控制是当前流域水污染治理的难题,利用同位素示踪技术对污染物来源及污染过程进行追踪是解决该问题的有效手段之一。综述了近几年同位素技术在国内外水环境污染源解析研究中的应用状况,简要介绍了同位素技术的基本原理与特点,重点总结了稳定同位素技术在示踪水环境中不同污染物及其迁移转化过程的研究进展;提出同位素示踪技术与传统水化学方法相比,有其独特的优势,但也存在一些不足,结合传统水化学分析和荧光光谱等技术,可提高同位素技术的示踪效率及环境友好程度;对同位素示踪技术的应用前景进行了展望。The sources identification and pollution process control of contaminants in aquatic environment is still a challenge in watershed pollution management.Isotope technology for tracing pollutants sources and the pollution processes is one of the effective methods to solve this problem.The application situations of isotope technology in water pollution sources research at home and abroad in recent years were summarized.The basic principles and characteristics of isotope technology were introduced briefly.The research progresses in stable isotope technology for tracing different pollutants,as well as the corresponding migration and transformation processes in water environment were summarized.Compared with the traditional methods,e.g.hydrochemistry,it was proposed that isotope technology had its unique advantages,while limitations still existed.Combined with the traditional hydrochemistry and fluorescence spectroscopy,the efficiency and environmental friendliness of isotope technology could be greatly improved.The prospects for the application of isotope tracing technology in aquatic environment were carefully addressed.
