Acute toxicity of South China Sea LH crude oil and NO.0 diesel to three mariculture and multiplication organisms

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.
