Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
If you believe you have been exposed to carbon monoxide or are at risk of CO poisoning, Bruccoleri says you can call the Tennessee Poison Center at 1-800-222-1222. The Center is staffed 24/7, 365 ...
Carbon monoxide also binds to the hemeprotein myoglobin. It has a high affinity for myoglobin, about 60 times greater than that of oxygen. [21] Carbon monoxide bound to myoglobin may impair its ability to utilize oxygen. [49] This causes reduced cardiac output and hypotension, which may result in brain ischemia. [21]
Pollutants are classified as primary or secondary. Primary pollutants are produced directly by a source and remain in the same chemical form after they have been emitted into the atmosphere. Examples include ash from a volcanic eruption, carbon monoxide gas from motor vehicle exhausts, and sulfur dioxide released from factories.
Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.
Carbon monoxide (CO): The EPA set the first NAAQS for carbon monoxide in 1971. The primary standard was set at 9 ppm averaged over an 8-hour period and 35 ppm over a 1-hour period. [10] The majority of CO emitted into the ambient air is from mobile sources.
Symptoms of carbon monoxide poisoning include: Tiredness. Nausea and dizziness. Headache. Chest or stomach pains. Vision problems. Loss of muscle control. What should you do if you smell natural ...
