Application of Nitrogen and Oxygen Isotopes to the Study of Groundwater Nitrate Contamination
氮、氧同位素在地下水硝酸盐污染研究中的应用

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.
