The Dispersant Used on the Oil Gushing in the Gulf

From WarOnYou.com:

The Amount Of Neurotoxin Pesticide Corexit Sprayed By BP Tops 1 Million Gallons

BP’s latest oil spill response update for June 4th says the total amount of the dispersant used in the Gulf of Mexico more than 1,021,000 gallons.

But what most people don’t know is that the active ingredient of the toxic chemical dispersant, which is up to 60% by volume, being sprayed by BP to fight the Gulf oil spill is a is a neurotoxin pesticide that is acutely toxic to both human and aquatic life, causes cancer, causes damage to internal organs such as the liver and kidneys simply by absorbing it through the skin and may cause reproductive side effects.

In fact the neurotoxin pesticide that is lethal to 50% of life in concentrations as little as 2.6 parts per million has been banned for use in the UK since 1998 because it failed the UK “Rocky shore test” which assures that the dispersant does not cause a “significant deleterious ecological change” – meaning it can delete an ecology or more specifically delete the entire food chain.

Corexit has also earned the highest EPA warning label for toxicity which means the effects of the toxic chemicals to the eye are corrosive resulting in irreversible destruction of ocular tissue and other tissue with corneal involvement along with an burning that can persist for more than 21 days and effects to human skin are corrosive resulting in tissue destruction into the dermis and/or scarring.

Corexit was widely used after the 1989 Exxon Valdez spill and according to a literature review performed by the group the Alaska Community Action on Toxics was later linked with widespread long lasting health impacts in people including respiratory, nervous system, liver, kidney and blood disorders.

The “Human Health Hazards” are said to be “Chronic” for Corexit EC9527A according to the EPA.

So What Are These Dispersants Made Of That Makes Them Such a Powerful Neurotoxin Pesticide?
The main ingredients of Corexit is 2-Butoxyethanol which can make up to 60% of the dispersant and is known to be toxic to blood, kidneys, liver, and the central nervous system (CNS).

2-Butoxyethanol is also known to cause cancer, birth defects and has been found to cause genetic mutations and is a delayed chronic health hazard as well as an environmental hazardous material

Corexit also contains Arsenic, Cadmium, Chromium, Mercury, and Cyanide.

• Why allow the use of these toxic dispersants?

Well the EPA has ordered BP to stop using the dispersants but BP has refused.

The EPA justifies the use of dispersants because they are less toxic than oil and the cause less of an environment impact that oil along the coastline.

However the choice of using Corexit contradicts both of those justifications.

Corexit is lethal in as little as 2.6 parts per million where oil is lethal in 11 parts per million meaning that Corexit is over 4 times more toxic than oil.

Furthermore scientific studies show that oil dispersed with Corexit is 11 times more lethal than oil alone.

In fact the study referenced showed that crude oil was lethal at 4250 parts per million to killifish but combination of oil mixed with Corexit was lethal in as little as 317.7 ppm.

“Dispersed oils were more toxic than crude oils,” noted the report....

What are the Chronic Health effects of Corexit?
Here are some of the highlights from the MSDS for the active ingredient (2-butoxyethanol) – of Corexit (up to 60% by volume)
Severe over-exposure can result in death.
MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast.
The substance may be toxic to blood, kidneys, liver, central nervous system (CNS).
Repeated or prolonged exposure to the substance can produce target organs damage.
Repeated exposure to highly (this) toxic material may produce general deterioration of health by an accumulation in one or many human organs.
Hazardous in case of skin contact (permeator), of ingestion, of inhalation.
May cause adverse reproductive effects (maternal and paternal fertility, fetoxicity)
May cause birth defects (teratogenic)
May cause cancer (tumorigenic)
Penetrates intact skin easily and can cause systemic effects and central nervous system depression
Inhalation: May cause irritation of the respiratory tract. May affect behavior (analgesia), behavior/central nervous system (headache, drowsiness, dizzness, stuttering, coma, weakness, ataxia, slurred speech, loss of coordination and judgement, personality changes, analgesia, blurred vision, tremor, excitement, somnolence), sense organs, the gastrointestinal tract (nausea, vomiting), metabolism (metabolic acidosis), respiration (dyspnea), urinary system (kidneys – hematuria, albuminuria, polyuria, oliguria, renal failure), liver (liver damage).
Exposure to high vapor concentration may also cause corneal or lens opacity of the eyes.
Ingestion: Causes gastrointestinal tract irritation with nausea, vomiting, diarrhea. May affect behavior/central
nervous system (see inhalation), respiration (dyspnea), metabolism, cardiovascular system.
Chronic Potential Health Effects: Inhalation and Ingestion: Prolonged or repeated inhalation or ingestion may affect the liver, blood (changes in red blood cell count, pigmented or nucleated red blood cells, microcytosis with or without anemia, erythropenia, reticulocytosis, granulocytosis, leukocytosis), urinary system (kidneys -hematuria), metabolism (weight loss), endocrine system (spleen, thymus, pancreas). Prolonged or repeated inhalation of high concentrations may also cause lung hemmorrhage, congestion, bronchopneumonia.
Classified in Canada as CLASS D-1A: Material causing immediate and serious toxic effects (VERY TOXIC).
Classified in Canada as CLASS D-2B: Material causing other toxic effects (TOXIC)

The EPA warning about human health affects says:
People working with dispersants are strongly advised to use a half face filter mask or an air-supplied breathing apparatus to protect their noses, throats, and lungs, and they should wear nitrile or PVC gloves, coveralls, boots, and chemical splash goggles to keep dispersants off skin and out of their eyes.
