Carbon monoxide is produced when organic materials such as gasoline, coal, charcoal, and trash are incompletely burnt. Virtually all stoves, furnaces, fires in open places and forests, factories, power plants give off carbon monoxide. The other significant source is from the incomplete burning of tobacco when smoked. This gas combines with hemoglobin, and reduces the oxygen canying capacity of blood, causing blurred vision, headache, and in extreme cases, unconsciousness, and even death. Automobiles emit a variety of hydrocarbons. These are a group of organic compound:; consisting of carbon and hydrogen.
