Abstract

Abstract: Hydrophytes absorbs and accumulates heavy metals and purifies the environment，therefore，owns high aesthetic and economic values. This study provided an important reference value for the selection of plant species for phytoremediation of heavy metal Pb pollution. This experiment selected 3 common hydrophytes called Iris tectorum Maxim，Acorus calamus L.，Eichhornia crassipes（Mart.）Solms to study their resistance capacities to Pb²⁺ in different concentrations of Pb（NO₃）₂ waste by using hydroponics. Then the effect of Zn²⁺ on the absorption of Pb²⁺ by water hyacinth was tested under the lead and zinc multiple-contamination. The results showed that the water hyacinth to higher concentration of Pb（NO₃）₂ waste water presented a certain resistance，in the low and middle concentration of waste A. calamus showed better resistance，and followed by I. tectorum Maxim. Under the multiple-contamination condition，synergistic effect and antagonistic effect between lead and zinc in E. crassipes（Mart.）Solms were respectively observed in the terms of uptake in different range of concentration. Different plant tissues absorbed and accumulated the Pb differently. Moreover，the heavy metal content in the aboveground of 3 hydrophytes was higher than that in the underground part. The metastasis ability of lead inside plants was not obvious，thus they do not belong to hyper accumulator. Therefore，these 3 hydrophytes are not suitable for treatment of high concentration wastewater containing lead.

Key words: heavy metal, hydrophyte, Pb²⁺, multiple-contamination, resistance
