摘要
氮是水体中的主要污染物之一。近几十年来,随着工农业的发展,使得水体中氮的污染呈上升趋势,并在今后可能会持续,最根本的解决方法是找到源头,从根本上切断污染途径以达到消除氮源的污染。在查阅相关文献的基础上,阐述了水中用同位素追踪研究氮的来源的研究进展和存在的问题,对于评价氮的污染现状、污染控制和环境管理具有十分重要的意义。
Nitrate is one of the chief pollution in water. During the past years, due to the development of industry and agriculture,there is a increasing tendency in the aspect of nitrate pollution. And the situation would exist for along time in the future. The most fundamental solution is to track the source of nitrate and cut it off so as to eliminate the nitrate of water. This paper summarizes recent trends and existing problems in identification of nitrate source using Isotope methods though relative literatures,which is a far-reaching meaning for assessing the pollution situation,controlling pollution and management in environment.
