Tetraethyllead (commonly styled tetraethyl lead), abbreviated TEL, is an organolead compound with the formula Pb(C 2 H 5) 4.It was widely used as a fuel additive for much of the 20th century, first being mixed with gasoline beginning in the 1920s.
Robert Arthur Kehoe (/ ˈ k iː h oʊ /; November 18, 1893 – November 24, 1992) was an American toxicologist and a dominant figure in occupational health. [1] [2] Working on behalf of the lead industry (including the manufacturing of leaded gasoline and lead-acid batteries), Kehoe was the most powerful medically-trained proponent for the use of tetraethyllead as an additive in gasoline.
Lead is widely understood to be toxic to multiple organs of the human body, particularly the human brain. Concerns about even low levels of exposure began in the 1970s; in the decades since, scientists have concluded that no safe threshold for lead exposure exists. [2] [3] The major source of lead exposure during the 20th century was leaded ...
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
Tetraethyllead has been recognized as a contributor to soil, air and water lead pollution, and is toxic to humans.While leaded gasoline made engines more efficient, lead pollution has increased by over 625 times previous levels in the past century due partly to pollution by leaded fuel.
