采用紫海胆Paracentrotus lividus和贻贝Mytilus galloprovincialisa 48小时以及糠虾幼体Siriella armata 96小时的胚胎-幼虫生物测定法来评估以下制剂的急性毒性：（1）海岸线清洁剂CytoSol； (2) CytoSol 的含水馏分加轻质原油； (3) 使用 CytoSol 对充满 Prestige 石油泄漏（发生于 2002 年 11 月 19 日）残留物的岩石沿海基质进行中试规模处理后产生的径流。贻贝是对 CytoSol 和径流影响最敏感的生物（EC50 分别为 8.0 μL/L 和 64.3 mL/L），糠虾对径流最不敏感（EC50> 200 mL/L）。预测的无影响环境浓度 (PNEC) 是根据对径流最敏感的物种的无观察影响浓度计算得出的。通过简单合理的稀释模型估算预测环境浓度（PEC），并根据处理面积和模型中考虑的变量值计算PEC/PNEC比值。讨论了治疗操作管理的影响。
The application of embryo–larval bioassay with the purple sea urchinParacentrotus lividusand the musselMytilus galloprovincialisat 48 hours, and with neonates of the mysidSiriella armataat 96 hours, was used to evaluate the acute toxicities of the following preparations: (1) the shoreline cleaning agent CytoSol; (2) the water-accommodated fraction of CytoSol plus a light crude oil; and (3) the runoff from a pilot-scale treatment with CytoSol of a rocky coastal substrate impregnated with residues from thePrestigeoil spill (which occurred on November 19, 2002). The mussel was the most sensitive organism to CytoSol and runoff effects (EC50= 8.0 μL/L and 64.3 mL/L, respectively), and the mysid was the least sensitive to the runoff (EC50> 200 mL/L). The predicted no-effect environmental concentration (PNEC) was calculated from the no observed–effect concentration of the species most sensitive to the runoff. The predicted environmental concentration (PEC) was estimated from a simple and reasonable dilution model, and the PEC/PNEC ratio was calculated according to the area treated and the values of the variables considered in the model. Implications for the management of the treatment operations are discussed.
