YOU MAKE ME SICK... . ~JP Originals & Exposes By justpiper Write comment *A Char find* By Stephen C. Webster Raw Story Shrimpers who were exposed to a mixture of oil and Corexit dispersant in the Gulf of Mexico suffered severe symptoms such as muscle spasms, heart palpitations, headaches that last for weeks and bleeding from the rectum, according to a marine toxicologist who issued the warning Friday on a cable news network. Dr. Susan Shaw, founder and director of the Marine Environmental Research Institute, said during a CNN broadcast that after personally diving the oil spill in late May, a “very fiery sore throat” plagued her from inhaling fumes coming off the water. Because she was covered from head to toe in a protective suit, Dr. Shaw was spared direct exposure. Shrimpers who had bare-skin contact with the mixture of oil and Corexit, she said, were not so lucky. During her segment with anchor Rick Sanchez, Dr. Shaw specified that stories shrimpers had told her were from when BP was deploying “the more toxic” Corexit 9527. BP has allegedly switched to Corexit 9500, which Dr. Shaw has also taken to task in a widely-publicized essay. The company responsible for producing the various Corexit formulas is Nalco, Co., which was created by former members of the boards of directors at BP and Exxon. Their product is essentially by the oil industry, for the oil industry. That’s why, even in the face of an alternative like Dispersit which is half as toxic as Corexit, Nalco’s product is still in much greater supply. Gulf toxicologist: Shrimpers exposed to Corexit “bleeding from the rectum” CNN, July 9. 2010: Rush Transcript Excerpt Susan Shaw, Marine Toxicologist: If I can tell you what happens — because i was in the oil — to people… Shrimpers throwing their nets into water… [then] water from the nets splashed on his skin. … [He experienced a] headache that lasted 3 weeks… heart palpitations… muscle spasms… bleeding from the rectum… And that’s what that Corexit does, it ruptures red blood cells, causes internal bleeding, and liver and kidney damage. … This stuff is so toxic combined… not the oil or dispersants alone. … Very, very toxic and goes right through skin. * Keep this in mind… Peter 3 weeks ago She’s wrong about the 9500 vs 9527. 9500 is actually more toxic than 9527. It was made to use in cold Alaskan waters & 9527 was meant for warm waters. 9500 is more toxic and less effective than 9527.

As a feature of CNNhealth.com, our team of expert doctors will answer readers' questions. Here are several questions related to the oil spill in the Gulf of Mexico for Dr. Gupta. From Jacque, Mobile, Alabama "What health problems could the dispersant Corexit cause? I still don't understand why BP continues to use it." Answer: Jacque, that's an interesting question. Hundreds of thousands of gallons of Corexit dispersants have been sprayed into the oil slick since April. It's banned in many countries including Great Britain. But it's approved by the EPA here in the U.S., despite the fact that it has been rated less effective and more toxic than many other EPA-approved dispersants. A lot of people know that now. I talked to EPA Administrator Lisa Jackson about that very thing and pointed out there's a list of 18 dispersants, and out of that list, this is one of the most toxic. It's unclear why BP continues to use it. Jackson said the EPA has encouraged BP to stop using this particular substance. I found the product information sheet on the website of the manufacturer of this dispersant. It's says it's classified as a hazardous substance, and it says you have to use adequate ventilation and certainly use some sort of mask or breathing apparatus when applying it. That certainly raises concerns when we see pictures of people working on the oil slick without any breathing protection. |

SPECIAL HANDLING AND WORKER PRECAUTIONS FOR STORAGE AND FIELD APPLICATION 1. Flammability: IMO: Non-flammable; DOT: Non-hazardous. 2. Ventilation: Use with ventilation equal to unobstructed outdoors in moderate breeze. 3. Skin and eye contact; protective clothing; treatment in case of contact: Avoid eye contact. In case of eye contact, immediately flush eyes with large amounts of water for at least 15 minutes. Get prompt medical attention. Avoid contact with skin and clothing. In case of skin contact, immediately flush with large amounts of water, and soap if available. Remove contaminated clothing, including shoes, after flushing has begun. If irritation persists, seek medical attention. For open systems where contact is likely, wear long sleeve shirt, chemical resistant gloves, and chemical protective goggles. 4.a. Maximum storage temperature: 170ºF 4.b. Minimum storage temperature: -30ºF 4.c. Optimum storage temperature range: 40ºF to 100ºF 4.d. Temperatures of phase separations and chemical changes: None V. SHELF LIFE The shelf life of unopened drums of COREXIT® EC9500A is unlimited. Containers should always be capped when not in use to prevent contamination and evaporation of solvents. VI. RECOMMENDED APPLICATION PROCEDURE 1. Application Method: COREXIT® EC9500A contains the same surfactants present in COREXIT® EC9500A and a new improved oleophilic solvent delivery system. Aerial Spraying - Aircraft provide the most rapid method of applying dispersants to an oil spill and a variety of aircraft can be used for spraying. For aerial spraying, COREXIT® EC9500A is applied undiluted. Typical application altitudes of 30 to 50 feet have been used, although higher altitudes may be effective under certain conditions. Actual effective altitudes will depend on the application equipment, weather and aircraft. Careful selection of spray nozzles is critical to achieve desired dose levels, since droplet size must be controlled. Many nozzles used for agricultural spraying are of low capacity and produce too fine a spray. A quarter-inch open pipe may be all that is necessary if the aircraft travels at 120 mph (104 knots) or more, since the air shear at these speeds will be sufficient to break the dispersant into the proper sized droplets. Boat Spraying - COREXIT® EC9500A may also be applied by workboats equipped with spray booms mounted ahead of the bow wake or as far forward as possible. The preferred and most effective method of application from a workboat is to use a low-volume, low-pressure pump so the chemical can be applied undiluted. Spray equipment designed to provide a five to ten percent diluted dispersant solution to the spray booms can also be used. COREXIT® EC9500A 9500 should be applied as droplets, not fogged or atomized. Natural wave or boat wake action usually provides adequate mixing energy to disperse the oil. Recent tests have indicated that a fire monitor modified with a screen cap for droplet size control may also be useful for applying COREXIT® EC9500A. Due to the increased volume output and the greater reach of the fire monitor, significantly more area can be covered in a shorter period of time. System Calibration - Spray systems should be calibrated at temperatures anticipated to insure successful application and dosage control. Application at sub-freezing temperatures may require larger nozzle, supply lines and orifices due to higher product viscosity. 2. Concentration/Application Rate: A treatment rate of about 2 to 10 U.S. gallons per acre, or a dispersant to oil ratio of 1:50 to 1:10 is recommended. This rate varies depending on the type of oil, degree of weathering, temperature, and thickness of the slick. 3. Conditions for Use: As with all dispersants, timely application ensures the highest degree of success. Early treatment with COREXIT® EC9500A, even at reduced treat rates, can also counter the "mousse" forming tendencies of the spilled oil. COREXIT® EC9500A is useful on oil spills in salt water. VII.
