Vertical Distribution and Pollution Assessment of Heavy Metals in Sediment Core of Lijiang River
摘要
Abstract
The vertical distributions of heavy metals (Cd、Cr、Cu、Zn、Pb、As and Ni) in the columnar sediments at 3 sampling sites in Lijiang River, Cuilin City were determined. The results showed that: similar change tendency existed among 7 heavy metals in the columnar sediments. The contents of heavy metals near Guilin City were higher than that far from the city in horizontal direction. The results of index of geoaccumulation evaluation showed that the pollution of 7 kinds of heavy metals in the column sediments far from the city was light, only Cd and Ni were in the non ~ middle pollution levels. Near city, the pollution elements in the sediment column were Cd, Cu, Zn, Pb and As, which mainly concentrated at the bottom and subsurface.关键词
