The chemicals that gas companies use - which can include water, sand, salt, citric acid, benzene or lead, according to a federal report – can be hazardous if not properly isolated and stored. Chemicals Used in Fracking and Their Purpose. Fracking, or hydraulic fracturing, is a process of extracting oil and natural gas from underground shale formations, by inducing the formation of fissures along the shale rock. These cracks are induced by pumping hydraulically pressurized fluids through the .
Subscriber Account active since. Although the boom is helping the US generate more energy on its own soil, a study published Monday, May 4 points out a potential health problem linked with the practice, known as hydraulic fracturing or "fracking.
Some of the chemicals common in the fracking fluids were also found in drinking water wells in Pennsylvania, albeit in trace amounts. Fracking has been designated as safe since a study by the Environmental Protection Agency found that it posed no risk to drinking water. Fracking is used to develop shale deposits by unlocking natural gas. Numerous ProPublica investigations, however, found fracking to be the common thread in more than 1, cases of water contamination across seven states, including dozens of cases of well failures in which the concrete or steel meant to protect aquifers cracked under high pressure.
This latest study is another, more severe example of that contamination. In addition, a congressional report found that the 14 leading US fracking companies injected Methanol appeared most often in hydraulic fracturing products in terms of the number of compounds containing the chemical. Vapors can cause eye irritation, headache and fatigue, and in high enough doses can be fatal.
Swallowing may cause eye damage or death. Sources: ProPublica ; U. Benzene, commonly found in gasoline, is also a known human carcinogen. Long time exposure can cause cancer, bone marrow failure, or leukemia. Short term effects include dizziness, weakness, headache, breathlessness, chest constriction, nausea, and vomiting. Toluene, ethylbenzene, and xylenes what channel is the haunting hour on harmful effects on the central nervous system.
The hydraulic fracturing companies injected Sources: ProPublicaU. Hydraulic fracturing companies injected more than 30 million gallons of diesel fuel or hydraulic fracturing fluids containing diesel fuel in wells in 19 states. Contact with skin may cause redness, itching, burning, severe skin damage and cancer.
Kerosene is also used. F ound in jet and rocket fuel, the v apor can cause irritation of the eyes and nose, and ingestion can be fatal. Chronic exposure may cause drowsiness, convulsions, coma or death.
It also can cause reproductive problems, high blood pressureand nerve disorders in adults. One of the hydraulic fracturing companies used gallons of a product containing lead between and Source: U.
Fumes are highly irritating, corrosive, and poisonous. Repeated ingestion over time can lead to hardening of the bones, and contact with liquid can produce severe burns. A lethal dose is 1. Absorption of substantial amounts of hydrogen fluoride by any route may be fatal. One of the hydraulic fracturing companies used 67, gallons of two products containing hydrogen fluoride in and Inhalation can cause respiratory tract irritation, nausea, vomiting, abdominal pain, fever or death. 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. Source: ProPublica. Dust is harmful if inhaled repeatedly over a long period of time and can lead to silicosis or cancer.
Ingestion of even one ounce of liquid can cause death. Exposure over a long period of time can cause lung damage and reproductive problems in women. 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.

What Is fracking?
Apr 07, · Another chemical used in fracking is napthalene. Napthalene itself is a chemical with white solid color and occurs naturally from burning process. The chemical commonly found in insecticide as well. As it works by producing toxic gas to kill insect, the toxic gas is also dangerous for human, especially for pulmonary system. The EPA at this time has not made any judgment about the extent of exposure to these chemicals when used in hydraulic fracturing fluids or found in hydraulic fracturing wastewater, or their potential impacts on drinking water resources. _progress_report_appendix_freenicedating.com (7 pp, 95 K). When millions of gallons of water are being used, however, the amount of chemicals per fracking operation is very large. For example, a four million gallon fracturing operation would use from 80 to tons of chemicals.
Fracking, or hydraulic fracturing, is a process of extracting oil and natural gas from underground shale formations, by inducing the formation of fissures along the shale rock. These cracks are induced by pumping hydraulically pressurized fluids through the formations. The nature and composition of this fracking fluid is elucidated in this article. Would you like to write for us? Well, we're looking for good writers who want to spread the word.
Get in touch with us and we'll talk Hydraulic fracturing also known as hydrofracturing, hydrofracking, or fracking involves injecting shale formations with pressurized fluids to release trapped oil and gas reserves.
The fluid used for this purpose is a mixture of water, sand, and a variety of chemicals. The chemicals to be used are based on the type of shale formations surrounding the fuel reserves.
The water in the fluid acts as a transporting agent for the chemicals and the sand. The sand acts to keep the fissures, caused by the pressurized nature of the injected fluid, to remain open. The different chemicals kill bacteria and other microbes, and help in dissolving minerals found in the shale.
With various possible chemicals that can be used, each company maintains its own tried and tested blend of chemicals to be used for the process. However, there are a few chemicals that are commonly and routinely used by all companies that carry out fracking. Each chemical serves a purpose and can be classified accordingly. Reduces the friction between the fluid and the pipe, and also between the fluid and its components.
Chemicals are used in the fracking process to make the fracturing of shale and recovery of gas an efficient process. Their use eliminates the need for further processing of the recovered gas.
If chemicals were not used, one would have to regularly carry out the tedious task of cleaning out the pipes due to deposition and precipitation of minerals, and also the action of bacterial byproducts. Also such depositions in the shale quarry itself would lead to inefficient recovery and re-entrapment of the natural gas. In addition, if friction reducers are not added, it would require more pressure and force to pump the water and sand mixture down to the rock bed.
In the absence of clay stabilizers, there arises a possibility of the clay loosening and the tunnel collapsing. There is also a chance of decreased gas recovery due to the formation of emulsions.
After a well has been fracked, it is usually rinsed or flushed with pressurized water. All the injected fluids are recovered to some extent, and treated and recycled to reduce the toxicity levels.
Newer ways are also being researched for possible reuse of the injected fracking fluid. What does something like an oxidizing agent state in the world of science and chemistry?
