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.
