Abstract:

This dataset contains survival and comet assay data for larval sheepshead minnows exposed to Corexit dispersant and its components. Survival, reported as percent survival, is reported for 1 day post hatch larval sheepshead minnow exposed to various concentration of Corexit after 24, 48 and 96 hours. Results are reported for three replicates for both 1 day post hatch larval and 1 day post fertilization embryo sheepshead minnows. One day post hatch larval percent survival is also reported after 48 hours exposure to various concentrations of dioctyl sodium sulfosuccinate (DOSS), LAS, and DAWN. Comet assay data for 1 day post hatch larvae exposed to Corexit and various components after 48 hrs is provided as median olive tail moment.

Purpose:

The objective of our study was to evaluate survival in sheepshead minnow embryos and larvae after short term exposures to a commonly used oil spill dispersant, Corexit.

Data Parameters and Units:

Timepoint (number of hours exposed to chemical where 24hr = 24 hours, 48 hr = 48 hours, 96 hr = 96 hours), Replicate # = replicate number, Concentration of chemical in mg/L (milligrams/Liter) chemicals included: Corexit 9500, Corexit 9527, DOSS (dioctyl sodium sulfosuccinate), DPnB (Dipropylene glycol n-butyl ether), Span 80, Tween 80, Tween 85, Petroleum distillates, 2-BE (2-Butoxyethanol), LAS, Dawn, 1dph = 1 day post hatch, 1dpf = 1 day post fertilization, Median OTM values = median olive tail moment, Survival = percent survival, SD = standard deviation
