The lead.......

leaded gasoline still available?
After decades of international pressure by a UN group, leaded gasoline is no longer being produced. The last leaded fuel has finally disappeared from gas stations. The last country in the world to sell it: Algeria

Leaded gas was commonly used many years ago but it was discovered that lead has undesirable side effects when lead is released into the air. Leaded gas was found to be harmful to the environment and humanity which resulted in the production of unleaded gas. You won't find leaded gas at the pump.

Leaded gasoline was gradually taken off the U.S. market

A combination of health and environmental concerns led to a ban on the sale of leaded gasoline for most uses in the United States. Mid-grade gasoline was introduced in 1986 as the United States began phasing out leaded gasoline.

who were alive prior to banning leaded gasoline all have small amounts of lead in their bodies, tied up in the bones, from the tetraethyl lead.

Leaded gasoline
In December 1921, while working under the direction of Charles Kettering at Dayton Research Laboratories, a subsidiary of General Motors, Midgley discovered that the addition of tetraethyllead (TEL) to gasoline prevented "knocking" in internal combustion engines.
Known for: Leaded petrol; CFCs
Died: November 2, 1944 (aged 55); Worthington, Ohio



Who invented the two deadliest substance of the 20th century?

Thomas Midgely Jr.
One Man Invented Two of the Deadliest Substances of the 20th Century. Thomas Midgely Jr. had, in the words of author Bill Bryson, “an instinct for the regrettable that was almost uncanny.” He is single-handedly responsible for creating two of the most destructive compounds in American history


Who discovered leaded gasoline?
Thomas Midgley, Jr.
(May 18, 1889 - November 2, 1944), an American chemist, developed the tetraethyl lead (TEL) additive for gasoline and chlorofluorocarbons (CFCs) and held over a hundred patents.
... and the reason lead was added to gasoline?
Why is lead so toxic?

Lead is bad for humans because it interferes with numerous enzymes inside the cells of these organs. This results in symptoms such as muscle and joint aches as well as constipation and overall fatigue. It damages our brains by interfering with how brain cells send messages and communicate

What is the biggest source of lead?
Homes near busy streets may have higher levels of lead in the soil. Today, lead still comes from metal smelting, battery manufacturing, and other factories that use lead. This lead gets into the air and then mixes with the soil near homes, especially if the home is near one of these sources.

What is lead used for?

Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.

A: "Lead" has two specific meanings. As a noun, lead (pronounced like "bread") is a metallic element. It's labeled on the periodic table as "Pb" and sometimes found in really old paint. The U.S. government banned lead paint in 1978.

very smart.... true i dealt
with this subject superficially.

chatillion: ... and the reason lead was added to gasoline?

Yes, it was later found out to be toxic. The reason lead was added to gasoline is it reduced pinging in high compression engines. Larger cars often required high octane fuel to run properly.
Leaded gas allowed the octane level to be increased and eliminated knock, which was a widespread problem in engines at the time. Since then Ethanol has mostly taken over from Leaded fuel, although it’s still sold for off-road equipment and aircraft.
hm... no... it was known
from the start...

The Romans used to drink out of lead goblets. So most of them went mad later in life. Could have explained some of their barbaric acts.
