Smog is a serious problem in many cities and continues to harm human health. [30] [31] Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma. [14]
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 ...
Carbon Monoxide: Carbon monoxide forms when carbon in fuel does not burn completely (incomplete combustion). The main source of carbon monoxide in air is vehicle emissions. As much as 95 percent of the carbon monoxide in typical U.S. cities comes from mobile sources, according to EPA studies.
Carbon monoxide detectors should be installed between knee to head height on every level of the home, especially those floors with fuel burning appliances and outside of sleeping areas.
Smoke inhalation is also a danger of smoke that can cause serious injury and death. [24] Processing fish while being exposed to smoke. Many compounds of smoke from fires are highly toxic and/or irritating. The most dangerous is carbon monoxide leading to carbon monoxide poisoning, sometimes with the additive effects of hydrogen cyanide and ...
Many homes around the world used solid fuels for cooking. These fuels release large amounts of carbon monoxide and fine particulate matter. [46] These chemical irritants when inhaled may cause different pulmonary conditions ranging from pulmonary epithelial cancer or acute pulmonary tract infection. [47]
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]
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.
