Toxicity and Accumulation of Selenite in Four Microalgae

【英文摘要】 The toxicity and bioaccumulation of selenite in four microalgae, Spirulina platensis, Dunaliella salina, Dunaliella bardawill and Phaeodactylum tricornutum cultured in the presence of selenite were investigated. Lower concentrations of selenite were generally nontoxic and frequently stimulated algal growth, while higher concentrations of selenite inhibited algal growth. Selenite was more toxic to D. salina and D. bardawill than to S. platensis and P. tricornutum . All algae cultured i...This work was supported by Natural Science Foundation of China (39270539)and the Science and Technology Commission of Fujian Province(Keyproject
