Evaluation of Heavy Metal in Soil and Dominant Plants of a Copper Mine Wasteland-the Center Region of Hebei
摘要
Abstract
The Cu, Pb, Zn ,Cr, Cd and As content of soil sample and dominant plants in a copper mine wasteland of the center region of Hebei province were determined respectively by sampling in -vestigation , chemical analysis , pollution evaluation and enrichment analysis in this paper .Then soil pollution condition and enrichment characteristics of dominant plants were analyzed .Results showed that the soil of this copper mine wasteland belonged compound pollution of Cu and As ;the content of Cu was 1870 mg· kg -1 , beyond 4.675 times of the national standard;the content of As was 84 mg· kg -1 , beyond 2.1 times of the national standard .Cu and As lightly polluted the sur-face soil at transport mining site and hillside site .While the contents of these heavy metal at factory and nearby village site were under the national standard .Cirsium segetum , Humulus scandens and Chloris virgata were recommended as ecological restoration plants of Cu and As polluted soil , be-cause they had not only a strong enrichment ability for Cu and As , but also had a good growth in this abandoned mine .Setaira viridis and hibiscus trionum could be adopted as restoration potential plants of Pb and Zn in the copper mine respectively , because they had a strong enrichment and transfer ability for Pb and Zn from the root to stem .Other plants such as chenopodium album , cynanchum chinense , herba leonuri and matricariarecutita were resistant or tolerant for different heavy metal iron .These results provided basic materials and scientific references for treatment of heavy metal pollution in this copper mine .关键词
