No level of lead is safe in children, so even that is concerning.

If levels at the airport aren't higher than the "background level" elsewhere, our concern should focus on other factors.

Actually no, not for policy decisions.

Guaranteed kids will have levels medically too high is a policy problem. Immediately downwind of the interstate in the 70s was apparently a very bad place for kids to be, and policy fixed that (more or less).

Almost no kids will have high levels now, and those few with higher levels experimentally are from uncountable random sources rather than the point source airport, is not a useful aviation policy problem.

The issue is high level = any detectable level above zero, especially if man made and easily preventable.

Allowing leaded avgas has always been a policy decision to cater to GA over the health of, among others, children.

The main lead sources now are old water pipes and paint.

Both seem very countable and fixable.
