What it is + why it's regulated

Tetraethyllead is a chemical compound that was historically added to gasoline to improve engine performance. It is a colorless, oily liquid that can be toxic. Because it contains lead, it is highly persistent in the environment and can accumulate in living organisms. The European Chemicals Agency (ECHA) lists tetraethyllead as a Substance of Very High Concern (SVHC) under the EU REACH regulation. This is because it is classified as toxic to reproduction and very toxic to aquatic life, with long-lasting effects. It is also a known endocrine disruptor. While its use in automotive fuel has been largely phased out in many countries, it may still be found in some specialized industrial applications, such as aviation fuel or as a chemical intermediate. The SVHC listing means companies must provide safety information about products containing it. This summary draws on public regulatory data; the linked source is authoritative.
