A colorless, odorless, and tasteless gas that results from the incomplete combustion of any carbon-containing substance is absorbed by the red blood cells more readily than oxygen which consequently can result in asphyxiation.
A poisonous gas found in fumes from car engines, from burning gas and cigarette smoke.
Dangerous gas produced by burning tobacco.
Colorless, odorless gas (CO) formed by the incomplete burning of organic materials (e.g., automotive fuel). Carbon monoxide is extremely toxic; by combining with hemoglobin, it can cause loss of oxygen transport to tissues, paralysis, and death.
A colorless almost odorless gas that is very poisonous. When breathed in it combines with hemoglobin in the red blood cells to form carboxyhemoglobin, which is bright red in color. This compound is chemically stable and thus the hemoglobin can no longer combine with oxygen. Carbon monoxide is present in coal gas and motor exhaust fumes.
This is a colourless, odourless tasteless, nonirritating gas formed by incomplete combustion of organic fuels. Exposure to CO is frequently due to defective gas, oil or solid-fuel heating appliances. CO is a component of car exhaust fumes and deliberate exposure to these is a common method of suicide. Victims of fires often suffer from CO poisoning. CO combines reversibly with oxygen-carrying sites of haemoglobin (Hb) molecules with an affinity 200 to 300 times greater than oxygen itself. The carboxyhaemoglobin (COHb) formed becomes unavailable for oxygen transportation. In addition, the partial saturation of the Hb molecule results in tighter oxygen binding, impairing delivery to the tissues. CO also binds to Myoglobin and respiratory cytochrome enzymes. Exposure to CO at levels of 500 parts per million (ppm) would be expected to cause mild symptoms only and exposure to levels of 4,000 ppm would be rapidly fatal.
A poisonous gas resulting from the inefficient and incomplete combustion of organic fuels. CO is colorless, tasteless, and odorless and cannot be detected by the senses. Carbon monoxide is distributed widely; it is found in the exhaust gas from the internal combustion engines in most motor-powered vehicles, and in sewers, cellars, and mines.
A poisonous, colorless, odorless gas produced when substances are burned.
An odorless, colorless, poisonous gas, produced mainly during combustion of fossil fuels, such as coal and gasoline.
Carbon monoxide is a poisonous gas that is colorless, odorless, and invisible. It is composed of one carbon atom bonded to one oxygen atom, with the chemical formula CO. This toxic gas is present in vehicle exhaust fumes and is produced when coal, gas, or oil is burned inefficiently.
Carbon monoxide is a toxic gas due to its ability to bind with hemoglobin, the oxygen-carrying molecule in red blood cells. This binding prevents the blood from effectively transporting oxygen to the body’s tissues, resulting in oxygen deprivation and asphyxiation. Acute high-level carbon monoxide poisoning initially presents symptoms such as dizziness, headache, nausea, and faintness. Prolonged inhalation of the gas can lead to loss of consciousness, permanent brain damage, and even fatality. Chronic low-level exposure to carbon monoxide over time may cause symptoms such as fatigue, nausea, diarrhea, abdominal pain, and overall discomfort.
A highly toxic gas that is both colorless and odorless, carbon monoxide is produced when coal and other substances undergo incomplete combustion. It can be found in domestic coal gas and is known for its paralyzing effects on the body’s muscle system, which occur long before a person loses consciousness. This paralyzing action prevents individuals who may have reconsidered their actions from escaping the danger of the gas, particularly if they attempted suicide by inhaling it. Carbon monoxide is also a component of sewer gases and afterdamp (the poisonous gas released in coal mines after explosions). It has been detected after explosions of shells or bombs in confined spaces. Interestingly, the skin of those who have succumbed to carbon monoxide poisoning often displays a peculiar and attractive pink coloration.
