摘 要:为探究表面活性剂对海洋棘皮动物的影响,测定了十二烷基苯磺酸钠(SDBS)和消油剂对刺参(Stichopus japonicas)幼参的急性毒性。结果显示,SDBS对刺参幼参的72 h-LC50和96 h-LC50分别为2.50和1.71 mg·L-1;消油剂对刺参幼参的96 h-LC50为7498.94 mg·L-1。刺参幼参相对于多刺裸腹溞(Moina macrocopa)和脊尾白虾仔虾(Palaemon carincauda)对SDBS的敏感性较高,相对于安氏伪镖水蚤(Pseudodiaptomus annandalei)对SDBS的敏感性则较低,SDBS对刺参幼参的毒性明显大于十二烷基磺酸钠(SDS),消油剂的96 h-LC50远远大于SDBS和SDS,毒性非常小,但这仅是对刺参幼参而言,大多数研究忽视了消油剂自身对生物体存在的影响,因此这方面的研究工作还需要继续开展。To investigate the effects of surfactant poUutants on marine echinoderms, the acute toxicity of so- dium dodecyl benzene sulfonate (SDBS) and oil dispersant to juvenile sea cucumber (Stichopus japonicus) was studied. Results showed that 72 h-LC50 and 96 h-LC50 of SDBS to juvenile sea cucumber were 2.50 and 1.71 mg· L^-1, respectively and 96 h-LC50 of oil dispersant to juvenile sea cucumber was 7498.94 rag. L1. Juvenile sea cucumber was found more sensitive to SDBS than to Moina macrocopa and Palaemon carincauda, and lower sensitive to SDBS than to Pseudodiaptomus annandalei. SDBS had higher toxicity than SDS to juvenile sea cucumber. Oil dispersant 96 h-LC50 was fa greater than that of SDBS and SDS, indicating that the toxicity was very low to juvenile sea cucumber (Stichopus japonicus). Most studies neglected oil dispersant impact of the biology, the research of this aspect work is worth to be carried out.
