苯并[a]芘和9,10-二甲基蒽对皱纹盘鲍（Haliotis dis-cus hannai）早期发育的毒性研究

论文摘要

为探究海洋中多环芳烃（PAHs）对海洋生物的毒性作用,以皱纹盘鲍（Haliotis discus hannai）为受试生物,采用半静水式实验方式,探讨了2种多环芳烃苯并[a]芘和9,10-二甲基蒽对皱纹盘鲍早期发育的毒性效应。在不同浓度的苯并[a]芘和9,10-二甲基蒽作用下,观察皱纹盘鲍的卵子受精率、胚胎发育时间和幼体死亡率。结果表明,高浓度的多环芳烃处理组与对照组相比,卵子的受精率显著降低,胚胎发育时间和幼体死亡率显著增加,与处理浓度之间存在显著的剂量-效应关系（P<0.05）。3～12 d中,苯并[a]芘对皱纹盘鲍幼体的LC10分别为11.6、8.18、7.67和7.66 mg·L-1,9,10-二甲基蒽对皱纹盘鲍幼体的LC10分别为14.91、14.11、12.82和9.64 mg·L-1。苯并[a]芘毒性大于9,10-二甲基蒽。
