摘要(Abstract)：

为初步探讨内分泌干扰物多环芳烃对海洋桡足类生物所产生的生物效应,研究了萘对火腿许水蚤(Schmackeria poplesia)的急性毒性作用及其在1.6μg·L-1、16μg·L-1、160μg·L-1浓度下对火腿许水蚤变态率、存活率、繁殖力、性别比和体长的影响.结果显示,萘对火腿许水蚤48hLC50和96hLC50分别为4589.34μg·L-1和1559.55μg·L-1;各浓度萘均引起火腿许水蚤幼体的变态率显著降低;160μg·L-1萘条件下,火腿许水蚤的存活率、产卵率和抱卵雌体比率均显著降低;各浓度的萘对火腿许水蚤的性别比和体长均未造成显著影响.研究表明,在目前的环境浓度下,多环芳烃(萘)对海洋桡足类生物可能造成的生态风险较低.
