From Al Jazeera: “The dispersants used in BP’s draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber,” Dr Riki Ott, a toxicologist, marine biologist and Exxon Valdez survivor told Al Jazeera. “It should be no surprise that solvents are also notoriously toxic to people, something the medical community has long known”.
The dispersants are known to be mutagenic, a disturbing fact that could be evidenced in the seafood deformities. Shrimp, for example, have a life-cycle short enough that two to three generations have existed since BP’s disaster began, giving the chemicals time to enter the genome.
Pathways of exposure to the dispersants are inhalation, ingestion, skin, and eye contact. Health impacts can include headaches, vomiting, diarrhea, abdominal pains, chest pains, respiratory system damage, skin sensitisation, hypertension, central nervous system depression, neurotoxic effects, cardiac arrhythmia and cardiovascular damage. They are also teratogenic – able to disturb the growth and development of an embryo or fetus – and carcinogenic.
Cowan believes chemicals named polycyclic aromatic hydrocarbons (PAHs), released from BP’s submerged oil, are likely to blame for what he is finding, due to the fact that the fish with lesions he is finding are from “a wide spatial distribution that is spatially coordinated with oil from the Deepwater Horizon, both surface oil and subsurface oil. A lot of the oil that impacted Louisiana was also in subsurface plumes, and we think there is a lot of it remaining on the seafloor”.
From the end-notes on this must read article:
“Corexit’s label clearly states it can cause kidney failure and death and the MSDS (Material Safety Data Sheet) specifically warns, “Do not contaminate surface water” with it. Additionally, toxicity testing in regards to marine species shows little tolerance by all forms of sea life; thus, applying it on spills as a preferred response method increases the toxicity of the spilled oil on which it is used,” Pedigo emphasized.
“The toxic dispersants add absolutely nothing to EFFECTIVE RESPONSE.
There is no scientific basis for it, and their use violates The Clean Water Act, EPA’s charter and common sense. All stakeholders continue doing the same thing over and over again, with the exact same negative outcome—although the EPA calls the toxins in dispersants’ reasonable tradeoffs’, Corexit and dispersants like it, have a horrible track record”, said Steven Pedigo, CEO OSEI.
