Phase Out of Leaded Gasoline

Phase Out of Leaded Gasoline

The Clean Air Act of 1970 gave the government the power to better regulate gasoline. In 1973, the EPA mandated the production of unleaded gasoline as a means of protecting catalytic converters, devices used to limit the pollutant emissions of automobiles. (Leaded gasoline proved completely incompatible with the devices.)  The phase out of leaded gasoline didn’t begin until 1976, with further reductions in 1985 and 1986. The 1990 amendments to the Clean Air Act required the complete elimination of lead from gasoline by 1996.

Cry Wolf Quotes

Personally I can quite agree with Dr. Thompson’s wholesome point of view, but still I am afraid human progress cannot go on under such restrictions and…they must be allowed to proceed if we are to survive among the nations.

There is no evidence that lead in the atmosphere, from autos or any other source, poses a health hazard.

John L. Kimberley, executive director of the Lead Industries Association, Testimony, New York City Council’s Committee on Environmental Protection. The New York Times.

In summary, epidemiologic evidence supports the position that airborne lead in the concentrations found in the general ambient atmosphere is, at most, a minor contributor to lead in blood. The increment of quantity of the airborne lead contribution even if it can be deduced, is biologically meaningless.
