Plastics and Chemicals Industries Association. In the five centuries between the work of Arnold and that of Priestley, carbon monoxide was studied and described by a number of prominent alchemists and chemists. Today we have a fairly sophisticated understanding of the mechanism by which carbon monoxide poisoning occurs. Carbon monoxide consists of one carbon and one oxygen atom connected by a triple bond. Many made special mention of the toxicity of the gas. The gas was first prepared synthetically by the French chemist Joseph Marie François de Lassone (1717–1788) in 1776, although he mistakenly identified it as hydrogen. As exposure increases, a person may lose consciousness and go into convulsions. "Carbon Monoxide Poisoning." The poisonous character of carbon monoxide has been well known for many centuries. "The Conference and Kyoto Protocol." Carbon monoxide is a compound of carbon and oxygen with the chemical formula CO. There has been a significant decline in outdoor CO levels in the United States as a result of decreased automotive emissions of carbon monoxide. Encyclopedia.com. "Carbon monoxide 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. In all three procedures, the carbon monoxide component of the gas mixture produced in the reaction can be separated out from the other gases. Death is a common final result. Chemical Compounds. The Merck Index. Since carbon monoxide is odorless, tasteless, and colorless, these monitors are invaluable in alerting people to possible exposure. Exposure to CO can be reduced by assuring adequate ventilation when near any combustion source. 4 Related Records Expand this section. . .

Recent nanotechnology advances (those technologies involving microscopic devices) have developed a nanoparticle catalyst made of nonreactive metals, helping to reduce more efficiently such poisonous gases as nitrogen oxides and carbon monoxide. Water gas is made by a similar process, by passing steam over hot coke. Carbon monoxide is flammable and capable of forming an explosive mixture with air. Chemical Compounds. Carbon monoxide has three major industrial uses. Known mechanisms include carbon monoxide binding to hemoglobin, myoglobin and mitochondrial cytochrome c oxidase and restricting oxygen supply, and carbon monoxide causing brain lipid peroxidation. In one procedure, air is passed over hot coke, graphite, or anthracite coal to make producer gas, a mixture of carbon dioxide, carbon monoxide, hydrogen, and water vapor. For example, copper(II) oxide, CuO, and iron(III) oxide, Fe2O3, are both reduced to the metal by carbon monoxide. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Amorphous carbon, buckminsterfullerene, graphite, and diamond are all inorganic. Carbon and oxygen do not form an ionic compound. Intercellular spaces— The spaces between cells in tissue. ." Bernard pointed out that carbon monoxide has a strong tendency to replace oxygen in the respiratory system. WHO, Geneva.

Carbon monoxide, or “CO,” is an odorless, colorless gas that can kill you. . About Carbon Monoxide. Low-level exposure can cause flu-like symptoms including shortness of breath, mild headaches, fatigue, and nausea. As early as the late 1200s, the Spanish alchemist Arnold of Villanova described a poisonous gas produced by the incomplete combustion of wood that was almost certainly carbon monoxide. UXL Encyclopedia of Science. Additionally, the hemoglobin does not release the carbon monoxide as it does the oxygen. Question 7. Carbon monoxide is the twelfth most abundant gas in the atmosphere. There are a number of important C 1 compounds produced from both natural and anthropogenic activities (Table 16.9). Raub, J. ." Commercial methods for producing carbon monoxide often depend on the direct oxidation of carbon under controlled conditions. An inadequate supply of oxygen can occur in enclosed, poorly vented spaces, such as the interior of houses, garages, and cars. New York: Oxford University Press, 2002.

Carbon monoxide bonds with iron in hemoglobin to form carbonmonoxyhemoglobin, a complex somewhat similar to oxyhemoglobin. It was discovered in the 1960s that CO can be endogenously produced in the body by heme oxygenase (HO) metabolism of heme to produce CO, iron, and biliverdin. Levels of COHb over 40 percent can be lethal. Combustion— A form of oxidation that occurs so rapidly that noticeable heat and light are produced. The symptoms of CO poisoning range from dizziness, mild headaches, and nausea at lower levels to severe headaches, seizures, and death at higher levels.

Carbon monoxide is produced from fuel-burning appliances, such as space heaters, furnaces, stoves, and vehicles. These gases consist of carbon-hydrogen compounds which, when oxidized, are converted to carbon monoxide, carbon dioxide, and water. The products in this case are hydrogen (50%), carbon monoxide (40%), carbon dioxide (5%) and other gases (5%). Handbook of Inorganic Chemicals. Rahway, NJ: Merck and Company, 1989, pp. Someone exposed to high concentrations of carbon monoxide may actually begin to suffocate as his or her body is deprived of oxygen.
