| 摘 要： | 硝酸盐是地下水中难以去除的稳定污染物之一,是地下水氮(N)污染的主要形式.不同氮来源的硝酸盐氮、氧(O)同位素组成不同,可利用N、O同位素并结合其他同位素技术示踪硝酸盐污染源,识别反硝化过程,对于有效控制污染源和评估地下水对硝酸盐污染的恢复自净能力有重要意义.本文介绍了N、O同位素技术在地下水硝酸盐污染源追踪和反硝化过程的识别方面的原理和应用以及目前发展状况.

| Abstract: | Nitrate is one of the conservative contaminants which can't be removed easily in groundwater;moreover,it is the main form of nitrogen(N) contamination in groundwater.The nitrogen and oxygen(O) isotopes in nitrate from various sources have different compositions.Tracing the source of nitrate contamination and identifying denitrification with the technique of nitrogen,oxygen and other isotopes will be useful in the effective control of the contamination source and the estimation of the capability of groundwater in remediation of nitrate contamination.This paper deals with the theory,application and development of the technique of nitrogen and oxygen isotopes in tracing the source of nitrate contamination in groundwater. |
