gasoline that has not been treated with a lead compound

danger
In addition to the hydrocarbons present in normal gasoline, leaded gasoline contains tetra-ethyl lead or other lead alkyls for their anti-knock effect.
Lead was added to gasoline in the 1970s as an anti-knock agent to improve engine performance. However, it was later discovered that lead in gasoline was harmful to both human health and the environment, leading to its phase-out in the following decades.
In the past we used gasoline with a lead additive in it. Since lead is a heavy metal and can cause birth defects, the US government required that gasolines be lead-free.
Diesel fuel does not have lead added, but it is not the same as unleaded gasoline.Diesel fuel does not have lead added, but it is not the same as unleaded gasoline.
Actually, the first gasoline was unleaded. Sometime in the 1940s lead was added to increase the octane rating. Environmental legislation in 1975 began the phase-out of leaded gasoline.
No, leaded gasoline is not a heterogeneous mixture. It is actually a homogeneous mixture where the lead additive is uniformly distributed throughout the gasoline.
One main reason for lead pollution in India is the widespread use of leaded gasoline in vehicles. When leaded gasoline is burned, it releases lead particles into the air, which can then contaminate soil and water sources. This can lead to serious health issues for people exposed to lead pollution.
A leaded gasoline is one that has a lead-containing compound in it. For many years the number one anti-knock agent was tetra-ethyl-lead. After epidemiological research showed that the lead dust coming from car exhausts was a major cause of lowered intelligence in children the use of this chemical was quickly phased out. The use of any lead compound in gasoline has been a Federal offence for some years now. Leaded gasoline is still available as a high octane aviation gasoliine.
Lead in soil can leak into water supplies and wells. Lead is toxic and can cause severe brain damage or death.
