摘要
通过研究河南安阳—林州地区、河北省石家庄市和邯郸市以及北京市丰台地区地下水氮污染,结果发现随着水文地质条件的演化,地下水中NO3-和NO2-含量的差别很大,这一现象不能单纯地用硝化作用和反硝化作用来解释。本文认为A.Mulder和A.A.Van de Graal等发现的厌氧铵氧化作用对解释地下水中NO3-和NO2-含量的差别具有指导意义,并指出研究反硝化作用与厌氧铵氧化作用需要将分子生物学方法与同位素示踪技术相结合进行,厌氧铵氧化作用的发现为同位素技术的应用开辟了一个新领域,将分子生物学与同位素示踪技术相结合来研究环境问题特别是水环境问题将是未来科学发展的必然趋势。
Through the research on the nitrogen pollution of groundwater in Anyang-Linzhou area in Henan Province,Shijiazhuang City and Handan City in Hebei Province,and Fengtai area in Beijing City,this paper finds that the difference between NO-3 and NO-2 content in groundwater is very large with the evolution of the hydrogeological conditions,and the phenomenon cannot be simply explained by nitrification and denitrification.Based on the study of domestic and international literatures,the paper believes that the anaerobic ammonium-oxidizing presented by Mulder and Van de Graal is significant for explaining the difference between NO-3 and NO-2 content.A new field in the application of isotope technique is opened up due to the discovery of anaerobic ammonium-oxidizing,and combining molecular biology with isotope trace technique to solve environmental problems,especially the water environment,is an inevitable trend of the scientific development in the future.
