![]() Carbon monoxide (CO) is a poisonous gas.Internal combustion engines often don't have enough oxygen available to completely oxidise the fuel, so toxic by-products are produced. Catalytic ConvertersĬatalytic converters are devices used to reduce emissions from an internal combustion engine (such as those found in cars). As a result, detectors should be placed at least five feet above the floor. Carbon monoxide is lighter than air, so it rises. UnsplashĬarbon monoxide detectors give out a loud, high-pitched alarm when the carbon monoxide levels of a room exceed a certain limit. Running car engines inside can lead to a dangerous build-up of carbon monoxide. Make sure that any appliances are properly installed and maintained regularlyĬhimneys are kept clean and well-maintainedĭon't use barbecues or camping stoves indoors or inside a tent, or leave engines running inside garages To prevent carbon monoxide poisoning in the home, it's important to: Poison Prevention: Carbon Monoxide Detectors and Controls When haemoglobin binds to carbon monoxide, it creates carboxyhaemoglobin instead of oxyhaemoglobin. As a result, it becomes very difficult for oxygen to bind to haemoglobin due to competition for the same binding sites. The haemoglobin in red blood cells is up to 300 times more likely to take up carbon monoxide molecules than oxygen. If carbon monoxide is inhaled, it can rapidly accumulate in the bloodstream. ![]() An oxygen molecule has a choice of four specific binding sites on the haemoglobin molecule. This protein combines with oxygen molecules to form oxyhaemoglobin, allowing easy transport of oxygen from the lungs to the tissues. ![]() These small, biconcave cells contain a red protein called haemoglobin. To understand how carbon monoxide affects the body, you first need to know about red blood cells. The formula equation is:Ĭommon domestic sources of carbon monoxide pollutants include: PropertyĬarbon monoxide is produced by the incomplete combustion of carbon-based fuels. This table summarises the differences between carbon monoxide and carbon dioxide. Their high bond dissociation energy is what makes these gases inert (unreactive). In second place is the bond found in molecules of nitrogen gas (N ≡N), at 946 kJ/mol. The bond dissociation energy is the amount of energy required to break the molecule apart.The C ≡ O bond in carbon monoxide is the strongest, with a bond dissociation energy of 1072 kJ/mol.
