摘　　要：近年来,海洋环境激素污染日益严重,为了考察环境激素对海洋微藻的生物毒性效应,进而评估其对海洋生态系统的影响,该实验研究了三氯卡班、邻苯二甲酸二丁酯、三丁基氯化锡三种环境激素对海洋小球藻(Chlorella sp.)、眼点拟微绿球藻(Nannochloropsis ocutala)、球形棕囊藻(Phaeocystis globosa)和东海原甲藻(Prorocentrum donghaiense)4种海洋微藻的急性毒性效应。结果表明,三种环境激素均可显著抑制该4种微藻的生长。三氯卡班对4种微藻的96 h-EC50分别为108.19μg·L-1、63.21μg·L-1、60.73μg·L-1和57.58μg·L-1;邻苯二甲酸二丁酯对4种微藻的96 h-EC50分别为1.42 mg·L-1、1.02 mg·L-1、1.47 mg·L-1和1.21 mg·L-1;三丁基氯化锡对4种微藻的96 h-EC50分别为3.5μg·L-1、4.36μg·L-1、0.6μg·L-1和0.6μg·L-1。三种环境激素对四种海洋微藻的毒性强弱顺序为三丁基氯化锡>三氯卡班>邻苯二甲酸二丁酯。Environmental hormone pollution is becoming more and more serious in marine environment recently. In order to evaluate the impact of environmental hormones on marine eco-system,the acute toxic effect of three environmental hormones on four marine microalgae was investigated. Results showed that the growth of microalgae including Chlorella sp.,Nannochloropsis ocutala,Phaeocystis globosa and Prorocentrum donghaiense was significantly inhibited by the three environmental hormones. The 96 h median effective concentrations（96h-EC50） of triclocarban for Chlorella sp.,N. ocutala,P. globosa and P. donghaiense were 108.19 μg·L-1,63.21 μg·L-1,60.73 μg·L-1and 57.58μg·L-1,respectively. The values of 96 h-EC50of dibutyl phthalate for four microalgae were 1.42 mg·L-1,1.02 mg·L-1,1.47 mg·L-1and 1.21mg·L-1,and those of tributyl tin chloride for four microalgae were 3.5 μg·L-1,4.36 μg·L-1,0.6 μg·L-1and 0.6 μg·L-1,respectively. The toxic intensity of the three environmental hormones to marine microalgae was in the order of tributyl tin chloride triclocarban dibutyl phthalate.
