Toxicity of chemically enhanced water accommodated fraction (CEWAF) of MC252 crude oil and Corexit 9500 to 4 deep-sea crustaceans

Laboratory toxicity tests were completed with each species using chemically dispersed MC252 oil for 48 hours. Species exposed were Systellaspis debilis, Sergia sp, Sergestes sp, and members of the order Euphausiidae. Percent mortality at each exposure level was used to determine threshold concentrations via dose response modelling.

本研究针对各受试物种，采用经化学分散处理的MC252原油开展了为期48小时的实验室毒性试验。受试物种包括弱体莹虾（Systellaspis debilis）、Sergia属未定种、Sergestes属未定种，以及Euphausiidae目类群成员。基于各暴露浓度下的死亡率百分比，通过剂量-响应建模确定了临界暴露浓度。
