Tetraethyllead used to be a fuel additive that is now banned. Honestly my head is already spinning after 5 minutes of trying to make sense of all this terminology. Good luck. https://en.wikipedia.org/wiki/Persistent_organic_pollutant https://en.wikipedia.org/wiki/Persistent_organic_pollutant https://en.wikipedia.org/wiki/Persistent,_bioaccumulative_and_toxic_substances https://en.wikipedia.org/wiki/Persistent,_bioaccumulative_an... https://en.wikipedia.org/wiki/Tetraethyllead https://en.wikipedia.org/wiki/Tetraethyllead https://en.wikipedia.org/wiki/Organolead_chemistry https://en.wikipedia.org/wiki/Organolead_chemistry
