Sorry, but barium has so many uses in industry, agriculture, and construction to be able to trace any of it back to the visible exhaust plane of a
high flying airplane. Especially when you consider that barium is one of the most common elements you can find in dirt, that to not
find it in
samples would be odd.
Now consider the size of the particles in a trail. They are extremely small, in the order of a couple of microns. Something this size at that
altitude will take at least a day to fall to a level where a person will be exposed to it. And that does not include the things that can't be
controlled, like wind and updrafts. When the rock in aerosol from a volcano can circle the world for days, to expect ice crystals and a small amount
of soot to fall straight down to the ground and mess you up is impossible. Nothing can fall from that height smaller than large hail. I've yet to
see "chemtrails" claiming 'chem-hail', but give it time and there will probably be claims of "chem-hail" sometime soon.
