Luckily, CO is quickly removed from the atmosphere by microorganisms in the soil. Small amounts of this gas are extremely dangerous. Poorly ventilated areas such as parking garages and highway tunnels are especially vulnerable areas because CO can kill without warning.The Environmental Protection Agency uses its Air Quality Index to provide general information to the public about air quality and associated health effects. An Air Quality Index (AQI) of 100 for any pollutant corresponds to the level needed to violate the federal health standard for that pollutant. For carbon monoxide, an AQI of 100 corresponds 9 parts per million (averaged over 8 hours) -- the current federal standard.
|EPA Air Quality Index||Levels
|0 - 50||Good||None|
|51 - 100||Moderate||None|
|101 - 150||Unhealthy for Sensitive Groups||People with cardiovascular disease, such as angina, should limit heavy exertion and avoid sources of CO, such as heavy traffic.|
|151 - 200||Unhealthy||People with cardiovascular disease, such as angina, should limit moderate exertion and avoid sources of CO, such as heavy traffic.|
|201 - 300||Very Unhealthy||People with cardiovascular disease, such as angina, should avoid exertion and sources of CO, such as heavy traffic.|
|301 - 500||Hazardous||People with cardiovascular disease, such as angina, should avoid exertion and sources of CO, such as heavy traffic; everyone else should limit heavy exertion.|
- People with cardiovascular disease, such as angina, are most at risk from CO. These individuals may experience chest pain and more cardiovascular symptoms if they are exposed to CO, especially when exercising.
- People with marginal or compromised cardiovascular and respiratory symptoms, women that are pregnant, or small children, are most at risk from CO pollution.
- In healthy individuals, exposure to higher levels of CO can affect mental alertness and vision.
