氮污染特别是地下水硝酸盐污染已成为一个相当普遍而重要的环境问题。地下水硝酸盐污染与人类健康和环境安全密切相关。为控制地下水硝酸盐污染,最根本的解决办法就是找到硝酸盐的来源,减少硝态氮向地下水的输送。由于不同来源的硝酸盐具有不同的氮、氧同位素组成,人们利用NO3-中δ15N和δ18O开展了硝酸盐污染源识别研究。本文综述了利用氮、氧同位素识别地下水硝酸盐污染源及定量硝酸盐污染源输入的研究进展及目前存在的问题,并提出几个值得重视的研究方向。

Nitrogen pollution particularly nitrate pollution of groundwater has become a very common and important environmental issues.Nitrate pollution of groundwater is closely linked with human health and environmental security.In order to control nitrate pollution of groundwater,the most fundamental solution is to dentify the source of nitrates and reduce the nitrate input to the groundwater.Since δ15N and δ18O values vary in different sources of nitrate,Stable nitrogen（δ15N） and oxygen（δ18O） isotope data of NO-3 have been frequently used to identify NO-3 sources.This paper summarizes recent trends and existing problems in identification of nitrate source using dual Isotope methods and quantization of NO-3 source inputs and also proposes some aspects deserving careful study.
