| 摘 要： | 本文采用四极杆电感耦合等离子体质谱法测定了玄武湖和莫愁湖,及其相连的河道表层沉积物中Pb稳定同位素的比率.沉积物中208Pb/206Pb和206Pb/207Pb的比率范围分别为2.0931～2.1239和1.1558～1.1845.玄武湖、莫愁湖、护城河等采样点Pb稳定同位素比率,与文献中长江江苏段沉积物相近.其它河道采样点Pb稳定同位素组成与文献中南京市大气、土壤Pb稳定同位素比率相近.

| Abstract: | Pb stable isotope ratios in sediments collected from urban lakes and channels in Nanjing were determined by Inductively Coupled Plasma Mass Spectrometry.Results show that the range of Pb stable isotope ratios in sediments was 2.0931~2.1239 for 208Pb /206Pb and 1.1558~1.1845 for 206Pb/207Pb,respectively.The Pb stable isotope ratios in sediment from sampling sites(XW,MC,HC and ZF) are similar to the values in Yangzi river sediments.Pb stable isotope ratios in sediment from other sampling sites are consistent ... |
