Abstract: Juvenile sea cucumber Apostichopus japonicus with body weight of(0.15±0.05)g was exposed to two typical surfactants including sodium dodecyl sulfate(SDS) at a dose of 0, 5.00, 6.47, 8.38, and 14.00 mg/L and nonylphenol(NP) at a dose of 0, 500, 594, 708, 841 and 1000 μg/L in a 200 L plastic tank at water temperature of(16.5±1.5)℃ to evaluate the risk of typical surfactants for large marine benthic animals in a semi-static test system. It was found that LC50 of SDS for sea cucumber juveniles was 10.927 mg/L in 72 h and 9.834 mg/L in 96 h, with safe concentration(SC) of 0.983 mg/L and that LC50 of NP 1.12 mg/L in 72 h and 0.80 mg/L in 96 h, with SC of 0.08 mg/L(NP). Toxic effect of SDS on sea cucumber juveniles is mainly reflected in the induction of evisceration, but NP can lead the severe autolysis of body wall in sea cucumber. The findings indicated that the two surfactants had high toxicity to sea cucumber, which provides basic data for biotoxicity prediction of surfactant and water quality risk assessment in aquaculture.
