LEADED PETROL Meaning and
Definition
-
Leaded petrol, also known as leaded gasoline, is a type of fuel used in internal combustion engines that contains a certain amount of tetraethyllead (TEL) or tetramethyllead (TML) additives. These additives are primarily added to improve the performance and combustion characteristics of the fuel.
Leaded petrol was widely used in the past, particularly between the 1920s and 1990s. The addition of lead compounds in petrol enhanced its octane rating, which is a measure of the fuel's resistance to knocking or pinging. This significantly improved engine performance and allowed the use of higher compression ratios.
However, the use of leaded petrol has been largely phased out due to increasing concerns about its negative environmental and health impacts. The combustion of leaded petrol releases toxic lead compounds into the atmosphere, contributing to air pollution. Inhalation or ingestion of lead can lead to severe health issues, particularly affecting the central nervous system, kidneys, and blood cells.
In many countries, the usage of leaded petrol has been banned or restricted, and unleaded petrol has become the standard. Unleaded petrol, as its name suggests, does not contain lead additives. This transition to unleaded petrol has resulted in significant improvements in air quality and contributed to lower lead exposure in populations, particularly children.
Overall, leaded petrol refers to a type of gasoline that contains lead additives to enhance engine performance, but its use has been phased out globally due to environmental and health concerns.

Etymology of LEADED PETROL
The word "leaded petrol" is composed of two main components: "leaded" and "petrol".
The term "leaded" refers to the addition of tetraethyl lead (TEL) as a compound in petrol (commonly known as gasoline in North America) to boost its octane rating and improve engine performance. The practice of adding lead to petrol began in the early 1920s and was widely used until the late 20th century.
The word "petrol", on the other hand, originated from the British English term "petroleum spirit". The term "petroleum" comes from the Latin words "petra" which means "rock" and "oleum" meaning "oil". The suffix "-um" indicates that it is a neuter noun.
Therefore, the phrase "leaded petrol" simply refers to petrol (gasoline) that contains added lead compounds.
