Why does it have lead?
- jumpingmice 7y agoBecause of leaded fuel and the principle of conservation of species and mass. Every atom of lead that ever passed through an American gas pump is currently laying around on American soil.

- reaperducer 7y agoProbably from tetraethyl lead, which wasn’t banned in common fuels until the 70’s in the US. Except in California, which had leaded fuel well into the 90's for rich people's collector cars. Another example of the do-as-I-say-not-as-I-do sorts of things that happen in California.
- undersuit 7y agoYep, California banned leaded fuel for automotives in 1992, 4 years before the United States federal government followed up. https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-phaseout-leaded-gasoline.html https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-ph...

- Joelexander 7y agoLead used tp be a very common additive in gasoline. In the US there was no legislation to reduce it's use until the 1973 and it wasn't fully banned until 1996. It can be assumed that any well-trafficked road during or before this period has substantial lead contamination.
- kleton 7y agoIt's still allowed in general aviation. Let your lawmakers know if that bothers you. The stakeholders in this case happen to be a small, wealthy minority.
- ItsDeathball 7y agoWealthy on a global level definitely, but as far as Americans go there are lots of relatively normal middle-income hobbyists in GA. You can buy and operate a plane for less than a used car if you're frugal about flying.
