As far as I can tell, the numbers seem to indicate that living near a

ultrafine particle emissions. It seems that demanding that aircraft
takeoffs
be reduced or shut down entirely at an airport would be equivalent to
demanding that the number of vehicles on a major highway be reduced or
shut down. The options to neighbors appears to be roughly the same in
both cases.

Did the study include particulate matter from tire dust that occurs
comes from tires rolling down the freeway? That matter would be minimal
from an airport but available in quantity from freeways.

The whole thing sounds to me like cherry-picked data.

Typical of shills to try and change the subject.

Subject being inhaled airborne particulates, since when is bringing up
another common major source of them "changing the subject"?

I support closing SM airport.

Of course you do. And any old cudgel will do, whether it makes sense or
not.

Obsessive much?
