Major Air Pollutants: Carbon Monoxide |
|
Carbon Monoxide (CO)
-gas -colorless, odorless, poisonous, blue flame, slightly lighter than air -produced when fuels carbon are burned with too little oxygen or at too high temperatures -in the presence of adequate oxygen, most CO is immediately oxidized to CO2 (4)
The Sources -bi-product of high-temperature fuel burning -anything that burns fuel -cars, trucks, buses, motorcycles, scooters, etc. -gas stoves -non-electric furnaces -charcoal grills -lawnmowers -solid waste disposal -incineration of refuse
-high concentrations can be found in confined spaces like parking garages, poorly ventilated tunnels, or along roadsides during periods of heavy traffic -emissions are highest when engines are idling or decelerating (3) -dense traffic conditions and high air temperatures worsen emissions
