Abstract:

The main purpose for developing the current dataset were to determine whether use of Corexit dispersant enhanced in a dose response fashion the exposure of embryonic fish to oil constituents from DWH weathered oil (mousse) as compared to a South Louisiana Crude reference standard. This comparison was performed for freshwater (Zebrafish were the developmental model for which this data was preparative) and select salinities (extrapolative). These data demonstrate that Corexit under the conditions of the baffle test dispersed crude oil into water at only the highest Corexit concentrations (3.0 mg/l, 100 mg/l). At the highest Corexit concentration this amounted to nearly 30%. This was not true for a similar experiment with mousse with few mousse constituents dispersed into water. For treatments at which different salinities were measured only small changes were noted between the different salinities.
