Description:

This report is the first of a round of toxicity testing data for eight oil dispersants that have been authorized for use on the National Contingency Plan (NCP) Product Schedule, which is a list of authorized dispersants and other chemicals that may be used to respond to oil discharges. This report was initated as part of the EPA response to the explosion of the Deepwater Horizon oil exploration platform on April 20, 2010 and the period following the BP Oil spill in the Gulf of Mexico. The dispersants were tested on two aquatic toxicity test species; the mysid shrimp, Americamysis bahia and the inland silverside, Menida beryllina

Purpose/Objective:

Assess the acute toxicity of eight oil dispersants using two aquatic toxicity test species; the mysid shrimp, Americamysis bahia and the inland silverside, Menida beryllina. Results gained from these exposures were used to evaluate dispersant toxicity information provided in the EPA's NCP Product Schedule.
