After about a month of pressure from the public and interested parties like LEAN and LMRK, the chemical constituents of the dispersant COREXIT has been released to the general public.
We will be sending out a follow-up alert from our chemist Wilma Subra on what health concerns these chemicals hold for those exposed to them and the environment in which they are being released.
What are the chemical components of the dispersants COREXIT 9500 and COREXIT 9527?
The components of COREXIT 9500 and 9527 are:
