摘    要:采用化学品对藻类毒性测试的标准试验方法,分别研究了己烯雌酚和四溴双酚A单组分对小球藻生长及光合色素含量的影响,并用相加指数法评价了己烯雌酚和四溴双酚A双组分对小球藻的联合毒性效应.结果表明,藻细胞密度和光合色素含量随己烯雌酚和四溴双酚A浓度增加而明显下降,且均表现出较好的浓度-效应关系,其对小球藻的96h-EC50值分别为0.0248mg·L-1和0.0455mg·L-1;两者对小球藻96h的联合毒性效应为拮抗作用.

关 键 词:己烯雌酚  四溴双酚A  小球藻

Abstract:The toxic effects of Diethylstilbestrol and Tetrabromobisphenol A on the growth and content of photosynthetic pigments of Chlorella pyrenoidosa were investigated with a standard experiment method of evaluating chemicals’ toxic effects on algae.The joint toxicity of Diethylstilbestrol and Tetrabromobisphenol A to Chlorella pyrenoidosa was assessed with additive index.Results showed that the density and content of photosynthetic pigments of algae cells reduced with the increasing concentrations of Diethylstilbestrol and Tetrabromobisphenol A,exhibiting good concentration-effect relationships.The 96h-EC50 values of Diethylstilbestrol and Tetrabromobisphenol A were 0.0248mg·L-1 and 0.0455mg·L-1,respectively.The 96h-joint toxicity of Diethylstilbestrol and Tetrabromobisphenol A to Chlorella pyrenoidosa was antagonistic.
Keywords:Diethylstilbestrol  Tetrabromobisphenol A  Chlorella pyrenoidosa
