摘要
通过96h的急性毒性试验,研究了邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二辛酯(DOP)对三角褐指藻(Phaeodactylum tricornutum),小球藻(Chlorella spp.),扁藻(Platymonas spp.)和叉鞭金藻(Dicrateria sp.)四种海洋微藻的致毒效应,探讨了四种海洋微藻对DMP、DEP、DBP、DOP的耐受性及之间的相互作用。结果显示DMP、DEP、DBP、DOP在10～200mg/L的有机物浓度梯度下对四种微藻的生长均有不同程度的抑制,特别是在高浓度组下的抑制特别明显。四种微藻的耐受程度有所差别,其中三角褐指藻最为敏感,叉鞭金藻耐受性最强。
The toxicological effects of DMP,DEP,DBP and DOP on four marine microalgaes include Phaeodactylum tiocornutum,Chlorella spp.,Platymonas spp.and Dicrateria sp.were studied by acute toxicity tests of 96 h.Results showed that DMP,DEP,DBP and DOP inhibited the growth of four marine microalgaes at varying degree where concentration gradient of organic matter between 10~200 mg/L,particularly at higher concentration.Phaeodactylum tiocornutum was the most sensitive one and was influenced hardly,Dicrateria sp was the most tolerant one and the least influenced.
