In Gulf Spill, BP Using Dispersants Banned in U.K.
Source: ProPublica
The two types of dispersants BP is spraying in the Gulf are banned for use [1] on oil spills in the U.K. As EPA-approved products [2], BP has been using them in greater quantities than dispersants have ever been used [3] in the history of US oil spills.
BP is using two products from a line of dispersants called Corexit [4], which EPA data [2] appears to show is more toxic and less effective [5] on South Louisiana crude than other available dispersants, according to Greenwire.
