端足类河蜾蠃蜚对原油的敏感性

Species sensitivity of Corophium acherusicum (Crustacean, Amphipod)to crude oil

  • 摘要: 溢油发生后,端足类生物迅速消失并显示出非常高的初始死亡率。为定量评估原油对端足类生物的毒性影响,本文开展了原油水溶性组分(WAF)和原油与分散剂混合的水溶性组分(CEWAF)对端足类生物河蜾蠃蜚(Corophium acherusicum)的急性毒性实验,并结合收集的原油对海洋生物的急性毒性数据,利用物种敏感性分布曲线(species sensitivity distribution,SSD)评价河蜾蠃蜚对原油的敏感性。结果表明:WAF和CEWAF的96 h半致死浓度(LC50)分别为4.11 mg/L,0.85 mg/L;在WAF和CEWAF的SSD曲线中,河蜾蠃蜚的物种累积概率均低于30%。综上所述,端足类河蜾蠃蜚对原油敏感性较高。

     

    Abstract: After the oil spill, amphipods disappeared rapidly and showed very high initial mortalities. The study was investigated the acute toxic effects of crude oil on the Corophium acherusicum (Crustacean, Amphipod) by 96 h acute toxicity test.The data of acute toxicity of WAF and CEWAF to marine organisms of different trophic levels were screened and collected. The species sensitivity distribution (SSD) method was used to evaluate the sensitivity of C.acherusicum to crude oil. The results showed that WAF and CEWAF 96 h LC50 were 4.11 mg/L, 0.85 mg/L respectively. The calculated results of the cumulative probability showed that the C.acherusicum to WAF and CEWAF were lower than 30%. In summary, C.acherusicum was relatively sensitive to crude oil.
