Both producer and water gas are burned as fuels for a variety of industrial operations. Carbon monoxide’s toxicity is a consequence of its absorption by red blood cells in preference to oxygen, thus interfering with the transport of oxygen from the lungs to the tissues, in which it is required. "carbon monoxide 11th edition. 21 Dec. 2020 . "Carbon Monoxide Normally, oxygen is transported from the lungs to cells in red blood cells. Additionally, the hemoglobin does not release the carbon monoxide as it does the oxygen. . As early as the late 1200s, Spanish alchemist Arnold of Villanova (c.1238–c.1310) described a poisonous gas produced by the incomplete combustion of wood that was almost certainly carbon monoxide. Molecular Weight: 28.0101: Formula: CO: Melting Point-205.02 °C, 68 °K, … A number of methods are available for the commercial production of carbon monoxide. Vehicular Pollution. Boikess, Robert S., and Edward Edelson. ." The precise mechanisms by which the effects of carbon monoxide are induced upon bodily systems, are complex and not yet fully understood. Between 1772 and 1799, Priestley investigated the properties of carbon monoxide and recognized the difference between carbon monoxide and carbon dioxide. (December 21, 2020). ." Under ideal circumstances, a carbon-containing fuel such as charcoal, natural gas, or wood burns in air to form carbon dioxide and water. https://www.encyclopedia.com/medicine/encyclopedias-almanacs-transcripts-and-maps/carbon-monoxide, COLIN BLAKEMORE and SHELIA JENNETT "carbon monoxide © 2019 Encyclopedia.com | All rights reserved. Available from http://epa.gov/IAQ. This means that land and sea temperature increases changing to ecosystems, increasing storm activity and causing other extreme weather events. Encyclopedia of Public Health. Carbon monoxide is a highly toxic gas that has noticeable health effects even in relatively small concentrations. CO detectors are available to detect less obvious sources, such as a malfunctioning furnace. Carbon monoxide bonds with iron in hemoglobin to form carbonmonoxyhemoglobin, a complex somewhat similar to oxyhemoglobin. It is a colorless, odorless, tasteless, toxic gas. Carbon monoxide is a compound of carbon and oxygen with the chemical formula CO. Carbon monoxide is a very important industrial compound. Ring in the new year with a Britannica Membership, https://www.britannica.com/science/carbon-monoxide, Carbon Monoxide and Backbonding - Chemistry LibreTexts, United States Department of Labor - Occupational Safety and Health Administration - Carbon Monoxide Poisoning, carbon monoxide - Student Encyclopedia (Ages 11 and up). There has been a significant decline in outdoor CO levels in the United States as a result of decreased automotive emissions of carbon monoxide. Question 20. Carbon monoxide bonds to hemoglobin in the blood stream 200 times as efficiently as does oxygen. Carbon monoxide, with the chemical formula CO, is a colourless, odourless and tasteless gas. Someone exposed to high concentrations of carbon monoxide may actually begin to suffocate as his or her body is deprived of oxygen. Hydrogen is the chemical element of atomic number 1. Many made special mention of the toxicity of the gas. Commercial methods for producing carbon monoxide often depend on the direct oxidation of carbon under controlled conditions. Carbon monoxide is an organic dative covalent compound with the formula CO. UXL Encyclopedia of Science. Today a fairly sophisticated understanding is known of the mechanism by which carbon monoxide poisoning occurs. Hemoglobin: An complex iron-containing molecule that transports oxygen through the circulatory system. The simplest oxocarbon is carbon monoxide (CO). Brown, Theodore L., and H. Eugene LeMay Jr. Chemistry: The Central Science. U*X*L Complete Life Science Resource. Carbonmonoxyhemoglobin is, however, a more stable compound than is oxyhemoglobin. ." Carbon monoxide is used in industry primarily as a source of energy and as a reducing agent. Treatment must be prompt and includes respiratory assistance and the administration of oxygen, often with 5 percent carbon dioxide and sometimes under high pressure. Corrections? Cite this article Pick a style below, and copy the text for your bibliography. As for the molecular makeup of carbon monoxide, it consists of one carbon atom and one oxygen atom, giving it the abbreviated name of CO. Greenwood, N. N., and A. Earnshaw. New York: Harper & Row Publishers, 1981, pp. Additionally, the new absorbent was exposed in vitro to sevoflurane, desflurane, isoflurane, and enflurane to determine whether these anesthetics were degraded to either compound A or carbon monoxide.
