you picked a very bad news source. this reporting has been debunked. they failed to control for increased lead in environment. neighborhoods NOT under flight paths but in the same area also have higher lead levels. this is sponsored by land developers hoping to close KRHV

It's not like it's a controversial topic. It's a well known, well studied, and well documented effect.

Avgas is unnecessarily putting more lead into the air. Any amount of lead in the air is bad.

Do you have a citation for the debunking? The WA state legislature is trying to push through a bunch of unfunded mandates of dubious effectiveness on airports based on this study.

Always be skeptical of individuals who claim things are debunked without citing their sources.

Also, it is true that neighborhoods near the airport not in the flight path also have higher lead levels than average, but I'm not sure how that helps the case - there is elevated lead levels near airports, which can adversely affect your health.
