| Abstract: | Influence of MFI nano-zeolite on the bioaccumulation of waterborne Cu2+ and Cd2+ was investigated in medaka fish static exposure experiment.The results indicated that the bioaccumulation of tested metals was reduced by MFI nano-zeolite after 3 days exposure.Nevertheless,significant decrease in that influence was observed after 10 days of exposure.Additionally,clearance of copper and cadmium from medaka body could not be changed by MFI nano-zeolite.The adsorption behavior of MFI nano-zeolite was compared wit... |
