The FAA finally approved 100UL gas for small airplanes. I'm not sure how widely it's available now.

This is just for general aviation though. Jet fuel has no lead in it. Not that this means it’s healthy, just that jet exhaust pollution does not include appreciable amounts of lead.

Also also, shit tons of poor folk all over the country live in homes full of lead pipes and paint that their landlords are too cheap to fix.

Asbestos too, though that's less threatening as long as it's not being actively fucked with.

Generally speaking, it's better to cover up asbestos than it is to remove it. Remediation attempts can easily go wrong, moving the asbestos from "hidden and staying put under tiles" to "free floating dust in the air and your lungs". One of my parents' friends got mesothelioma from doing just that.
