海黍子和脆江蓠对重金属锌、镉富集的比较研究
Comparative study on heavy metal accumulation in Sargas-sum muticum and Gracilaria chouae
摘要
Abstract
The growth and accumulation of the heavy metals Zn and Cd in Sargassum muticum and Gracilaria chouaewere investigated for 15 days following exposure to different concentrations of these metals.The results de-monstratedthat the growth rates of these two algae were negativelycorrelated to the concentrations of metal solu-tions, whereasthe metal contentsin vivo were positivelycorrelated to the concentrations of metal solutions.In addi-tion, the metal contents in both algae increased remarkably on the thirdday of culture and continually kept increas-ingover the entire period of culture. The accumulation of Zn2+ was evidentlyhigher than that of Cd2+ in both algae. Under the sameexperimental conditions, the accumulation of Zn2+ and Cd2+was significantly higher inS. muticum-than inG. chouae. These findings may contribute to the selection of potential algae for the removal of heavy metals in aquatic environments.关键词
