摘要
氯污染特别是地表水硝酸盐污染已经成为人们普遍关注的环境问题.为有效控制地表水硝酸盐污染,最根本的方法就是确定硝酸盐污染源,减少硝酸盐的输入.不同来源的硝酸盐具有不同的氮、氧同位素组成,利用贿酸盐稳定氮、氧同位素对硝酸盐污染源进行示踪已经得到广泛应用.在分析不同来源硝酸盐δ15N与δ18O值的组成特征及其影响因素的基础上,对不同土地利用类型流域条件下同位素技术的应用方法和研究进展进行综述,并对目前研究存在的问题和未来的发展进行总结.
Abstract
Nitrogen pollution,particularly nitrate pollution in surface water,has become an universal concerned environmental issue.For the effective control of nitrate pollution of surface water,the most fundamental way is to determine the sources of nitrate contamination and reduce input of nitrate nitrogen.As nitrates from different sources are composed of different nitrogen and oxygen isotopes,tracing nitrate pollution sources by using nitrate stable nitrogen and oxygen isotopes has been widely used.In this researeh,the composition of different sources of nitrate δ15 N and δ18 O values and its influencing factors were reviewed,research progress and application methods of isotope techniques under the condition of basin in different land use types were reviewed.Finally,the current research problems and future development were summarized.
