邻苯二甲酸二甲酯(DMP)对海洋微藻的生态毒理研究

通过96h的急性毒性实验,研究了邻苯二甲酸二甲酯(DMP)对杜氏盐藻(Dunaliella salina)、绿色巴夫藻(Pavlova viridis)和三角褐指藻(Phaeodactylum tricornutum)三种海洋微藻的致毒效应,探讨了三种海洋微藻对DMP的耐受性及两者之间的相互作用。结果显示DMP对三种微藻的生长均有抑制作用,在DMP的处理浓度分别为0.1、10、40、80和200mg·L^-1时,与对照组相比,DMP生长抑制百分率分别为22.9～93.1%、42.1～82.2%和61.9～92.2%。DMP对对杜氏盐藻、绿色巴夫藻和三角褐指藻的EC₅₀值分别为103.3、43.9和0.12mg·L^-1。

Ecological toxicology of Dimethyl phthalate(DMP) to marine microalgae

The toxic effect of DMP on three marine microalage, Dunaliella salina, Pavlova viridis and Phaeodactylum tricornutum is studied by a 96 h acute toxicity experiment, the endurance of the algae to DMP and the interaction between them are discussed as well. The results showed that DMP did inhibit the growth of three algae. The growth inhibition rates of DMP to three algae are 22.9～93.1%、42.1～82.2% and 61.9～92.2%, respectively when compared with the control. EC₅₀ of DMP to Dunaliella salina, Pavlova viridis and Phaeodactylum tricornutum are 103.3,43.9 and 0.12 mg·L^-1, respectively.
