兰州市天水路和南滨河路交通干道土壤和植物重金属分布特征的分析
Distribution characteristics of heavy metalsin soil and plants of Tianshui Road andSouth Riverside Road in Lanzhou City
摘要
Abstract
Samples are collected from South Riverside Road and Tianshui Road of Lanzhou City,and distribution characteristics and potential ecological risk of heavy metals and Ca were evaluated.Mn and Ni contents have no significant difference,however,the amount of Cr,Pb,Zn and Cu in roadside soil is higher than that in campus,and the order of contamination degree is Cu>Pb>Cr,but Zn,Mn and Ni missed pollution level.The roadside soil of South Riverside Road and the control sampling soil contain higher Cr,Pb and Cu,and the pollution index(Pi) of Cr and Pb is less than 2 but more than 1,reaching the level of light pollution,the Pi of Cu is more than 2,reached a moderate level of pollution,but Zn,Mn and Ni do not meet pollution levels.Besides,the levels of Pb,Zn and Mn in the greening plant leaves of South Riverside Road were much higher than those in Tianshui Road.关键词
