Lead was for many years
primarily emitted to the atmosphere from motor vehicles that burned leaded
gasoline. Lead can affect the central nervous system and lead to
anemia. The young and the elderly are most susceptible to the harmful
effects of lead.
Over the last ten years, the lead content of fuels has been
reduced and, today, almost all fuels are lead free. With the
phase-out of leaded gasoline, exposure to this pollutant by
inhalation has become far less likely.
Ambient air concentrations of lead in Florida reflect
the decrease in auto emissions. Except for locations very near a
small number of stationary sources which emit significant amounts of lead
- such as secondary lead smelters - lead concentrations in Florida's air
are nearly zero.
