The Council is inviting proposals for an investigation into the toxicity of the dispersant Dasic EcoSafe OSD in comparison to the formerly stockpiled dispersant Corexit 9500A when applied to Alaska North Slope (ANS) oil under environmentally realistic conditions.
The proposal should consider toxic effects on one or more relevant species found within the Exxon Valdez oil spill (EVOS) region and the physical conditions (e.g., temperature and salinity) of the water in which they live. In addition to the toxicity of each dispersant, the effects of the dispersants mixed with ANS crude oil and ANS crude oil alone should be examined. Comparisons with Corexit 9500A and ANS crude oil may be based on direct laboratory comparisons or on historical studies, provided their relevance is well justified.
The final report will compare the observable effective concentrations of these substances and their effects on one or more species living in the EVOS region.
