    摘要
  • 摘要: 采用半静水法进行了南海原油和0#柴油对凡纳滨对虾(Litopenaeus vannamei)、翡翠贻贝(Perna viridis)和菲律宾蛤仔(Ruditapes philippinarum)的急性毒性试验。南海LH原油乳化液、0#柴油乳化液和0#柴油分散液对凡纳滨对虾的96 h半致死安全质量浓度(LC50)分别为3.25 mg · L-1、3.17 mg · L-1和2.40 mg · L-1，其对应的安全阈值分别为0.33 mg · L-1、0.32 mg · L-1和0.24 mg · L-1；南海LH原油乳化液和0#柴油乳化液对菲律宾蛤仔的96 h-LC50分别为15.93 mg · L-1和8.74 mg · L-1，对应安全阈值分别为1.59 mg · L-1和0.87 mg · L-1；0#柴油乳化液对翡翠贻贝的96 h-LC50为28.90 mg · L-1，安全阈值为2.89 mg · L-1。

     

    Abstract: We studied the acute toxicity of Nanhai LH crude oil and NO.0 diesel to Litopenaeus vannamei, Perna viridis and Ruditapes philippinarum. The results show that 96 h-LC50s of Nanhai crude oil emulsion, NO.0 diesel emulsion and NO.0 diesel dispersants to L.vannamei were 3.25 mg · L-1, 3.17 mg · L-1 and 2.40 mg · L-1, respectively, and the corresponding safety thresholds were 0.33 mg · L-1, 0.32 mg · L-1 and 0.24 mg · L-1, respectively. The 96 h-LC50 of Nanhai LH crude oil emulsion and NO.0 diesel emulsion to R.philippinarum were 15.93 mg · L-1 and 8.74 mg · L-1, respectively, and the corresponding security thresholds were 1.59 mg · L-1 and 0.87 mg · L-1, respectively. In addition, The 96 h-LC50 of NO.0 diesel emulsion on P.viridis was 28.90 mg · L-1, and the safety threshold was 2.89 mg ·L-1.
