There are many studies of this kind for Corexit 9500.
Suspicions have been fanned by the refusal of Nalco, the company that makes the dispersant, to publicly disclose the chemical formula for Corexit, which it calls proprietary.
Shortly after the Torrey Canyon incident, chemists began to search for less toxic and more effective alternatives, and, in 1968, a scientist named Gerard Canevari, with Esso, created the original formula for Corexit, the dispersant that was used in the BP spill.
On Monday, Representative Edward J. Markey, Democrat of Massachusetts, sent a letter to Ms. Jackson at the E.P.A. demanding details of the formula for Corexit products and information about any testing that had been carried out on the chemicals.
The material safety data sheets for Corexit 9527a classify the substance as an "Immediate (Acute) Health Hazard," a "Delayed (Chronic) Health Hazard," and a "Fire Hazard," advising those that handle this substance to "use personal protective equipment".
The materials safety data sheet says that for Corexit 9500 it has the potential to bioaccumulate which means work its way up through the food web.
Surfactant-based dispersants like Finasol, Corexit 9500, and Corexit 9527 can cause changes in ATPase activity, respiration, and death in Artemia, with the 48 h LC50 for Corexit 9500 at 21 mg/L and 52 104 mg/L for Corexit 9527.
11 In contrast to the MSDS for Corexit 9527, which assigns a "moderate" human health risk to this compound, 11 the 9500 MSDS lists the human health risk as "slight".
