The US Environmental Protection Agency (EPA) released peer reviewed results from the first round of its own independent toxicity testing on eight oil dispersants. EPA conducted testing to ensure that decisions about ongoing dispersant use in the Gulf of Mexico continue to be grounded in the best available science. EPA’s results indicated that none of the eight dispersants tested, including the product in use in the Gulf, displayed biologically significant endocrine disrupting activity. While the dispersant products alone – not mixed with oil - have roughly the same impact on aquatic life, JD-2000 and Corexit 9500 were generally less toxic to small fish and JD-2000 and SAF-RON GOLD were least toxic to mysid shrimp.
