The 10 Scariest Chemicals Used In Hydraulic Fracking

The 10 Scariest Chemicals Used In Hydraulic Fracking by Michael Kelley, March 16, 2012, Business Insider
A 2011 congressional report on the chemicals used in hydraulic fracking, states that the 14 leading hydraulic fracturing companies in the U.S. injected 10.2 million gallons of more than 650 products that contained chemicals that are known or possible human carcinogens, regulated under the Safe Drinking Water Act, or listed as hazardous air pollutants. … Methanol appeared most often in hydraulic fracturing products (in terms of the number of compounds containing the chemical). … The BTEX compounds – benzene, toluene, xylene, and ethylbenzene – are listed as hazardous air pollutants in the Clean Air Act and contaminents in the Safe Drinking Water Act. … The hydraulic fracturing companies injected 11.4 million gallons of products containing at least one BTEX chemical between 2005 and 2009. … In its 2004 report, the EPA stated that the “use of diesel fuel in fracturing fluids poses the greatest threat” to underground sources of drinking water. Hydraulic fracturing companies injected more than 30 million gallons of diesel fuel or hydraulic fracturing fluids containing diesel fuel in wells in 19 states. Diesel fuel contains toxic constituents, including BTEX compounds. Contact with skin may cause redness, itching, burning, severe skin damage and cancer. (Kerosene is also used. Found in jet and rocket fuel, the vapor can cause irritation of the eyes and nose, and ingestion can be fatal. Chronic exposure may cause drowsiness, convulsions, coma or death.) … Naphthalene A carcinogen … Inhalation can cause respiratory tract irritation, nausea, vomiting, abdominal pain, fever or death. … Sulfuric acid Corrosive to all body tissues. Inhalation may cause serious lung damage and contact with eyes can lead to a total loss of vision. The lethal dose is between 1 teaspoonful and one-half ounce. … Many of the hydraulic fracturing fluids contain chemical components that are listed as ‘proprietary’ or ‘trade secret.’ The companies used 94 million gallons of 279 products that contained at least one chemical or component that the manufacturers deemed proprietary or a trade secret. In many instances, the oil and gas service companies were unable to identify these ‘proprietary’ chemicals, suggesting that the companies are injecting fluids containing chemicals that they themselves cannot identify.”
