So what is in this dispersant, Corexit? http://en.wikipedia.org/wiki/Corexit One ingredient: http://en.wikipedia.org/wiki/2-butoxyethanol Butoxyethanol has an LD50 of 2.5g/kg in rats. Laboratory tests by the United States National Toxicology Program have shown that sustained inhalation of high concentrations (100 - 500 ppm) of 2-butoxyethanol can cause adrenal tumors in animals. American Conference of Governmental Industrial Hygienists (ACGIH) reports that 2-butoxyethanol is carcinogenic in animals. OSHA does not regulate the butoxyethanol as a carcinogen.[citation Moderate respiratory exposure to 2-butoxyethanol often results in irritation of mucous membranes of the eyes, nose and throat. Heavy exposure via respiratory, dermal or oral routes can lead to hypotension, metabolic acidosis, hemolysis, pulmonary edema and coma. The current ACGIH threshold limit value (TLV) for worker exposure is 20 ppm in the industrial atmosphere, which is well above the odor threshold of 0.4 ppm. Blood or urine concentrations of 2-butoxyethanol or its major toxic metabolite, 2-butoxyacetic acid, may be measured using chromatographic techniques to monitor worker exposure or to confirm a diagnosis of poisoning in hospitalized patients. A biological exposure index of 200 mg 2-butoxyacetic acid per g creatinine has been established in an end-of-shift urine specimen for exposed U.S. employees. U.S. Employers are required to inform employees when they are working with this substance. Butoxyethanol is listed in the U.S. state of California as a hazardous substance, though it was removed from the U.S. Environmental Protection Agency's list of hazardous air pollutants in 1994. 2-Butoxyethanol has come under scrutiny in Canada, and Environment and Health Canada recommended that it be added to Schedule 1 of the Canadian Environmental Protection Act (CEPA). The use of some common household cleaning products containing 2-butoxyethanol could expose people to levels 12 times greater than California's one-hour guideline, especially when indoor use is considered. These products are not required to list it on the label when diluted to a certain point. The safety of the products as normally used is defended by the American Chemistry Council and the Soap and Detergent Association, industry trade groups. I'll pass on being around this stuff and if it is harmful to lab rats and humans I'm betting it is harmful to fish, crab, shrim, etc. Another ingredient: http://en.wikipedia.org/wiki/Propylene_glycol Propylene glycol is known to exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters. This process can adversely affect aquatic life by consuming oxygen aquatic organisms need to survive. Large quantities of dissolved oxygen (DO) in the water column are consumed when microbial populations decompose ethylene glycol Andrew, not saying you are off base with regard to who's profiting and such. Just saying that from an exposure standpoint those humans getting airborne exposure and those creatures getting depleted oxygen exposure seem to all the makings for suffering.
