摘要
以微小小环藻（Cyclotella caspia）为测试藻种,研究了不同浓度的双酚A对微小小环藻的急性毒性效应.在双酚A（4,6,8,10,12 mg/L）作用下,藻细胞生长受到不同程度的抑制;藻细胞叶绿素a含量随着双酚A浓度的增加呈下降趋势;藻细胞SOD活性随着双酚A浓度和作用时间的变化基本呈现为从诱导到抑制的动态过程;4～6 mg/L双酚A对藻细胞形态影响不大,8～12 mg/L双酚A可导致藻细胞不易分裂,细胞体积增大,细胞内含物增多,细胞器受到不同程度的破坏.
The acute toxicities of BPA to Cyclotella caspia were studied in the paper. Algal growths were inhibited to certain degrees under different BPA mass concentrations （4, 6, 8, 10, 12mg/L）. With the increasing of BPA, Chlorophyll a showed decreasing trends. The SOD activities appeared a dynamic process changing from inducement to inhibition as the variations of time and the concentration of BPA. The morphology of the algal cells changed little when BPA is 4 -6 mg/L. The main effects of the algal cells at 8 - 12 mg/L BPA were the inhibition of cell division, the enlargement of cell volume, the appearance of cell inclusions and the damage of organelle.
