True, but unless you live really close to a busy airport, I doubt it's an issue. I live fairly close to a rural grass strip that sees moderate use. I have about 40ppm which is 10x less than the allowed limit for crops. It sounds like accumulation from lead based paint and leaded car gas is the issue in the article. Which makes sense since you generally can't fly low over cities anyways (disperses) and small planes are not huge emitters (low in numbers). |
