This paper summarizes the currently available information on gasoline
exposure to the general population. In general, the largest contributi
on to the time weighted exposures results from exposures while indoors
, which are influenced by the outside ail; indoor sources, and attache
d garages. Personal activities, including refueling and commuting, con
tribute significantly higher exposures but last for only a small porti
on of the 24-hr time weighted average. The highest exposed group inclu
des those individuals living near large service stations and those wit
h contaminated water supplies.
