TETRAETHYLLEAD Meaning and
Definition
-
Tetraethyllead, commonly abbreviated as TEL, is a highly toxic compound that consists of four ethyl groups bonded to a central lead atom. It is a strong neurotoxin and was historically used as an additive in gasoline to enhance engine performance and prevent engine knocking, which is the sound produced when the air-fuel mixture in the engine's cylinders ignites prematurely.
The chemical formula for tetraethyllead is (C2H5)4Pb, and it is a clear, colorless liquid with a sweet odor. Due to its toxic nature, TEL has been phased out and banned in many countries around the world since the 1970s.
Exposure to tetraethyllead can occur through inhalation, ingestion, or skin contact. Once absorbed into the body, it can lead to various health effects, particularly affecting the central nervous system. Acute exposure to TEL can cause symptoms such as confusion, dizziness, headache, and even seizures. Prolonged exposure can result in more severe health problems, including kidney damage, reproductive issues, and neurological disorders.
Although tetraethyllead is no longer widely used, traces of it still remain in contaminated soils, water, and air from past emissions and spills. The ongoing presence of TEL in the environment necessitates measures to monitor and mitigate its potential risks to human health and the ecosystem.
