Carbon monoxide is produced primarily by motor vehicles. It can reduce a person's ability to think clearly, and causes visual impairment and headaches if high enough concentrations are experienced for a long period of time.
Long-term monitoring in Florida shows a significant decrease in carbon monoxide concentrations. Urban areas which use to suffer occasional high levels of carbon monoxide are no longer violating the air quality standard.
As the result of vehicle emissions controls and local measures to reduce traffic congestion, Florida has not recorded a violation of the carbon monoxide standard since 1986.
