5种沉水植物对重金属富集能力的对比研究
Comparison of Heavy Metal Accumulation by Five Submerged Macrophytes
摘要
Abstract
In this paper, atomic absorption spectrometry was used to analyze the contents of Pb, Cd, Zn and Cu in the waterbody of Dongfeng canal of Huaihe River tributary as well as in such five common submerged macrophytes as Potamogeton crispus L., Hydrilla verticillata, Potamogeton pectinatus L., Myriophyllum spicatum, and Najas minor all grown in the water, aiming at comparison of the differences of submerged macrophytes on heavy metal accumulation. The results showed that the contents of heavy metals in the submerged macrophytes were much higher than the background values. Bioconcentration factor of Cu, Pb, Cd and Zn was 58~1515. Concentration of Zn was maximal. Maximal concentration was 242.42 mg/Kg, and bioconcentration coefficient was up to 1515. Various macrophytes had obvious different accumulation characteristics for different heavy metals. As a result, utilization of submerged macrophytes to remediate water environment polluted by heavy metals must be based on selection of suitable macrophytes according to different pollution elements.关键词
