It's funny people complains about lead paint here where defending the
use of leaded fuel.

I don't know if funny is the word I'd use. Until the advent of unleaded
fuels, the greatest environmental exposure to lead in developed nations was
the lead in fuel. In vivo lead levels have declined considerably since
unleaded fuels became widespread, but aviation fuels for piston engines still
contain lead, so it's entirely plausible that aviators are still being exposed
to lead regularly via this route.


What "route" would that be?
