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.
