十二烷基磺酸钠(SDS)对刺参幼参的急性毒性
Acute Toxicity of Sodium Dodecyl Sulfonate (SDS) on Juvenile Sea Cucumber (Stichopus japonicas)

摘要: 为探究表面活性剂对海洋棘皮动物的影响,测定了十二烷基磺酸钠(SDS)对刺参(Stichopus japonicas)幼参的急性毒性。结果显示,SDS对刺参幼参的72 h-LC50和96 h-LC50分别为15.03和10.89 mg·L-1。刺参幼参相对于常见的几种水生生物对SDS的敏感性较高,其生命周期较长,活动能力较弱,生活相对固定于一定的区域,因此,在监测海洋水体SDS污染时,刺参幼参是一种值得关注的生物。

Abstract: To investigate the effects of surfactant pollutants on marine echinoderms, acute toxicity of sodium dodecyl sulfonate (SDS) to juvenile sea cucumber (Stichopus japonicas) was studied. Results showed that 72 h-LC50 and 96 h-LC50 of SDS to juvenile sea cucumber were 15.03 and 10.89 mg·L-1, respectively. Juvenile sea cucumber was found to be more sensitive to SDS, compared with several common aquatic organisms. Besides, Stichopus japonicas has long life-spans, weak mobility and relatively stable habitats. Therefore, juvenile sea cucumber is worth consideration for monitoring SDS pollution in marine waters. -
