Default Re: Chemical Contrails over California?

Out of curiosity, to all the chemists and amateur chemists out there, is there even a single chemical out that that has a noticeable effect on humans in the one part per quintillion range? Because if contrails were to have any intended effect, the chemical sprayed would have to meet this test.
