【 摘 要 】

In this investigationantioxidant response and toxicity of metals in receiving water effluent minerin the Blanco river in Pseudokirchneriella subcapitata was assessed.The catalase activity, lipid damage through Tbars, the growth rate of was determined.The result showed an inhibition of the growth rate of P. subcapitatawhich correlated with increased catalase activity and the lipid liperoxidation.These responses were correlated with the concentrations of copper and iron.
