摘要/Abstract

摘要： 准确识别农业面源污染源是面源污染防治、环境政策落实的前提。不同来源的污染物含有不同的氮同位素,对比受污水体和潜在污染源的同位素组成,可直接识别污染源。目前国内外已经开展利用氮同位素对面源污染进行定性识别以及污染贡献率定量计算的研究,但缺乏对该技术识别面源污染的全局介绍。对氮同位素识别农业面源污染的基本原理进行了简要阐述,重点介绍氮同位素识别农业面源污染源的研究进展,结合研究现状讨论该技术现有的不足,并对未来发展方向作了综述。

Abstract: Accurately identifying the sources of agricultural NPS pollution is the premise to control pollution and to carry out environmental protection policies. By comparing the δ¹⁵N values of potential pollution sources and water samples, we can easily and directly figure out the sources based on the different δ¹⁵N values. Qualitative identification of NPS pollution and quantitative calculation on contribution rate by using δ¹⁵N values have been done by researchers in China and abroad. In this paper, the fundamental principles of using this isotopic tracer to identify the NPS pollution sources is briefly introduced. The research progress in this regard is highlighted, present limitations and future prospects of this method are also presented.

Key words: agricultural non-point source pollution, identification of pollution sources, stable N isotope, pollution contribution rate
