Tetraethyllead
Tetraethyllead
Tetraethyllead (pronounced: tet-ra-eth-yl-lead), often abbreviated as TEL, is a petrochemical compound that was once widely used as an additive in gasoline. Its chemical formula is (C2H5)4Pb.
Etymology
The term "Tetraethyllead" is derived from its chemical structure. It consists of four (tetra-) ethyl groups attached to a lead atom.
History
Tetraethyllead was first discovered in 1852 by German chemist Karl Jacob Löwig. However, it was not until the 1920s that it began to be used as a gasoline additive to increase the octane rating and reduce engine knocking. Its use was phased out in many countries in the late 20th century due to health and environmental concerns.
Health Effects
Exposure to tetraethyllead can lead to lead poisoning, which can cause a variety of health problems including neurological damage, kidney damage, and cardiovascular disease. It is particularly harmful to children, as it can interfere with their development.
Environmental Impact
Tetraethyllead is a persistent environmental pollutant. It does not break down easily in the environment and can accumulate in soil and water, posing a risk to wildlife and humans.
