It is presently believed that particle sizes in the 10 to 100 micron range would be suitable for the seeding purposes. Larger particles would tend to settle to the earth more quickly.
The effects of inhaling particulate matter have been widely studied in humans and animals and include asthma, lung cancer, cardiovascular issues, and premature death. The size of the particle is a main determinant of where in the respiratory tract the particle will come to rest when inhaled. Because of the size of the particle, they can penetrate the deepest part of the lungs. Larger particles are generally filtered in the nose and throat and do not cause problems, but particulate matter smaller than about 10 micrometers, referred to as PM10, can settle in the bronchi and lungs and cause health problems. The 10 micrometer size does not represent a strict boundary between respirable and non-respirable particles, but has been agreed upon for monitoring of airborne particulate matter by most regulatory agencies.

Congratulations AllSeeingI, you have with a tiny bit of assistance, brought Chemtrails to a whole new level of acceptance! I hope that you throw this thread in your signature links, spread it to other sites, and really share it!
Chemtrail believers have suffered long due to thinking a line in the sky is proof... THIS, what you have just shown, is a significant step toward proving chemicals are in fact being dumped in our skies.
I'd love to see actual verification of jet fuels, analysis of the chem- and contrails, but because of you I will stop ignoring Chemtrails threads!
reduce the amount of Solar radiation and heat and therefore to reduce Global Warming.
