中文摘要：

为了探讨蒽和UV-B辐射对底栖生物早期发育的影响,在实验生态学的条件下,选择海湾扇贝（Argopecten irradians）担轮幼虫和D型幼虫作为受试生物进行单一和联合急性毒性试验。结果表明：在实验的蒽浓度和UV-B辐射剂量下,随着蒽浓度和作用时间的增加,海湾扇贝担轮幼虫和D型幼虫的存活率逐渐降低;随着UV-B辐射剂量和辐射天数的增加,海湾扇贝担轮幼虫和D型幼虫存活率下降;在蒽和UV-B辐射共同作用对担轮幼虫和D型幼虫处理时,其两个发育阶段的存活率较两者单独作用的存活率均低很多;担轮幼虫较D型幼虫对蒽和UV-B辐射更敏感。

英文摘要：

The effects of anthracene and UV-B radiation on the early stage embryos development of benthos,and the single and joint acute toxicological effects of anthracene and UV-B radiation on the trochophore and D larvae of Argopecten irradians under the controlled laboratory conditions were studied.The results showed that with the increase of time and the anthracene＇s concentration or the increase of days and radiation does,the livabilities of the trochophore and D larvae declined.With the combination of anthracene and UV-B radiation,the liabilities of trochophore and D larvae were lower than those in the single action.Compared to D larvae,the trochophore was more sensitive to anthracene and UV-B radiation.
