Carbon Monoxide Emission




Carbon monoxide has no odour taste or colour and it is also non-irritating. Pure carbon monoxide provides no warning about its presence but in many circumstances, carbon monoxide is present in exhaust gases which are themselves irritating. Where carbon monoxide may be produced or present. The molecular formula  is CO. carbon monoxide emission where found to come from transportation sources, in the incomplete combustion of hydrocarbon in  automobiles the products    include  unburned  hydrocarbons, Nitrogen oxides, carbon monoxide, carbon dioxide and water. The types of auto emission are responsible for carbon monoxide poisoning and affect global environmental trends.


1.0          INTRODUCTION


Carbon monoxide is a toxic gas, but being colorless, odorless, testless, and initially non-irritating, it is very difficult for people to detect and the product formed by the incomplete combustion of materials containing carbon, the molecular formula is CO, carbon monoxide is usually present in the work place as a gas. It can however be liquefied and solidified. Carbon monoxide is produced in large amounts by several industrial processes. It is a colorless, odorless and tasteless gas that is slightly less dense than air. It is toxic to humans and animals when encountered in higher concentration, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived; having a role in the formation of ground-level ozone carbon monoxide consists of one carbon atom and one oxygen atom, connected by a triple bond that consists of two covalent bonds as well as one dative covalent bond. In co-ordination complexes the carbon monoxide ligand is called carbonyl.

In the presence of oxygen, including atmospheric concentrations, carbon dioxide

Coal gas, which was widely used before the 190s for domestic lighting, cooking and heating, had carbon monoxide as a significant fuel constitution. Some process in modern technology, such as iron smelting, still produces carbon monoxide as a by product.

Other natural sources of carbon monoxide include volcanoes, forest fires, and other forms of combustion. In biology carbon monoxide is naturally  produced by the action of heme oxygenase 1 and 2 on the heme from hemoglobin breakdown.

The most common symptoms of carbon monoxide poisoning may resemble other types of poisoning and infections; include symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a felling of weakness.

Carbon monoxide poisoning is the common most types of fatal air poisoning in many countries.
