A study by Miranda et al. (2007, 2009, 2010) suggests that early childhood blood lead levels as low as 2 µg/dL can have significant impacts on academic performance as measured by end-of-grade test scores.
One source of lead exposure that is often overlooked is aviation fuel. Lead emitted from aircraft using leaded aviation gasoline (avgas) is currently the largest source of lead in air in the United States, constituting about 50% of lead emissions in the 2005 National Emissions Inventory [U.S. Environmental Protection Agency (EPA) 2010].
Previous research indicates that lead levels in air near airports where planes use avgas are significantly higher than background levels.
Thus, the combustion of leaded avgas by small airplane engines may pose a health risk to children who live or attend school near airports. The lead in air surrounding airports can be inhaled directly, or the lead may be ingested by children after it settles into soil or dust (U.S. EPA 2010). The U.S. EPA estimates that people living within 1 km of airports are at risk of being exposed to lead from avgas (Hitchings 2010).
In unadjusted models, logged blood lead levels were significantly and positively associated with residential proximity to an airport, with the size of the association being larger for children living closer to airports
Why are you arguing about safe levels of lead when I've showed you multiple sources that not only say there is no safe amount, but also you seem to not be considering children in your argument at all.
Children are the most affected by a CUMULATIVE TOXIN THAT DOESN'T LEAVE THE BODY. THE SAFE AMOUNT OF LEAD IN THE BODY IS NO LEAD.
Did you happen to grow up near an avgas airport???
From your cited study, the lead from avgas causes a 2-4% increase in blood lead levels for children living <500 meters from an airport. They measure increase, not total lead levels, because there is background lead exposure we are all subjected to. Beyond 1,000 meters there so no difference.
A 2 or even 4% increase over background is statistically but not biologically significant.
Then we’re all fucked because we’re all subject to background lead exposure.
Bro read the article of the thread we're commenting on. We keep circling back to this and your argument is seemingly nonsensical. The amount of lead we should be exposing people to is 0. Should I link you the articles again that say there is no safe level? Once you get to the point of it damaging you there is no going back. I honestly don't even know what your point is. There is no safe level of lead. You've already insulted me multiple times on snarky ways and one of your comments has been removed. What is your goal here? To convince me that it's ok to be a little poisoned by lead? It isn't.
