Lead used to be used in gasoline because it helped avoid micro-weld wear in exhaust valves and reduce knocking, thus inhibiting pre-combustion. But the air pollution leaded fuel exhaust produced eventually resulted in the presently unleaded standard for most customer automobiles. But that's not the only advantage of unleaded gas, notes a recent study by Dr. Philip Landrigan. The study suggests that since the removal of Tetraethyllead from gasoline in 1976, blood lead amounts in the U.S. have decreased 80 percent and children's average IQ score has shot up by six points.

IQ increases surprising

Six IQ points is a lot for everyone, even if they are working on greater ones. The name Tetraethyllead was too negative for GM to sell it, so it had to shorten the name to Ethyl to industry it. Certainly, Landrigan’s study made ideal sense since we have known lead exposure can cause issues since the 1920s.

Production of Tetraethyllead had its issues. Toxicity levels were known to be quite high, contributing to lead poisoning. In 1924, workers at a DuPont factory in Ohio either passed away or went ridiculous from inhaling the “loony gas” of burned Tetraethyllead, so the public was understandably reticent.

Facts about affecting your body

The brain sends neurons signals, but that is all messed up with the Tetraethyllead getting in the way of neurotransmitters. The brain cannot communicate with the body when the NMDA receptors get blocked, making us insane.

Admittedly, the six-point IQ score boost since 1976 has been tied conclusively to the shift toward unleaded gas. But removing Tetraethyllead exhaust from the air certainly hasn't hurt anything - except perhaps your car's valves. They're replaceable, though.
