黑藻对有机氯农药去除特性研究
Removal of Organochlorine Pesticides by Hydrilla verticillata
摘要
Abstract
The potential function of hydrophytes for field bioremediation has been more and more concerned. In this work, a common hydrophyte, Hydrilla verticillata was selected to investigate its ability to remove α-HCH, γ-HCH and p,p'-DDT. The results showed that the biodegradation of α-HCH, γ-HCH and p,p'-DDT by Hydrilla verticillata followed first-order kinetics, and biodegradation rate constants were 0.086, 0.103 d-1 and 0.077 d-1, respectively. The bioconcentration factors of α-HCH, γ-HCH and p,p'-DDT by Hydrilla verticillata were significantly higher than 1, and in the order of p,p'-DDT>γ-HCH>α-HCH, α-HCH, γ-HCH and p,p'-DDT were mainly enriched in leaf. p,p'-DDD, the anaerobic product of p,p'-DDT, was detected in the experiment samples.关键词
