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.

Unfortunately, the atmosphere we’re now in prohibits objective scientists from coming forward.

Our stance has been that lead from gasoline does not and has not caused health problems, and I have not seen any data that convinces me differently.
There is no evidence that [leaded gasoline] has introduced a danger in the field of public health…lead is an inevitable element in the surface of the earth, in its vegetation, in its animal life, and that there is no way in which man has ever been able to escape the absorption of lead while living in this planet.
In contrast to popularized reports, there is no persuasive evidence that low-level lead exposure is responsible for any intelligence defects.
