yes, they comprise carbon dioxide and water vapor, not Barium and Aluminium as some have found in the chemtrails drops. Contrail does not last long.
If Contrails contain those toxic materials naturally then shouldn't authorities would have been banning them ??? Shouldnt some Health Authorities be concerned and voice their concerns already as part of the political games governments do ???
?????
you write nonsense and have no facts to back anything up, a picture of a vapour trail is not a conspiracy theory chemitrail, that part is fiction and created by you..
remember to keep the fact from fiction and the idea was to keep this thread as a joke, which it has been..
your starting to make me believe thata you actually believe this nonsense,, which is troubling..
at altitude the water vapour in the contrails form ice crystals, and they can last for incredible long periods of time. been studied for years and well researched and accounted for, please read all the links below and all the chapters involved.. its very easy science..
all types of chemical reactions come from the process
Particles related to aviation (principally sulfate aerosols and soot particles) are discussed in Chapter 3 together with contrail and cloud formation. Aircraft engines actually emit a mixture of particles (including metal particles and chemi-ions) and gases (e.g., SO2). These emissions evolve in the engine exhaust and the atmosphere to form a variety of particles mainly composed of soot from incomplete combustion and sulfuric acid (H2SO4) from sulfur in the aviation fuel. These particles are capable of seeding contrails and cirrus clouds, thus potentially changing the total cloud cover in the upper troposphere. The climate impact of clouds is a balance of their capabilities to reflect sunlight back to space and to trap outgoing infrared radiation from the Earth's surface. For high clouds, the latter effect is larger, and increased cirrus coverage would result in a warming tendency. (This effect is opposite in sign to that of surface emissions of SO2, which mainly affect low-altitude clouds and produce a cooling effect.)
Particles are also involved in the chemical balance of the atmosphere. It is well established that the sulfate aerosol layer in the stratosphere is critically important in determining the NOx budget there; any long-term changes in the surface area of particles would affect stratospheric NOx, hence ozone. The chemical issues related to particles are discussed in Chapters 2 and 4.

now do your own research and stop this nonsense,,
you harp on about things that are perfectly normal and rational and explained, and each time you get the answer, be it your websites are fake websites for books, or whatever, you just dont do the research and believe these lame **** notions which make you look even more foolish every day
its one thing for you yourself to not research these things, but to keep on repeating the same nonsense and push your ill informed views and links to the most unresearched and laughable fools out there..
who do you think your audience is on this site? people here are interested in facts.. just keep this a funny thread and light hearted, if you want people take you serious then it could be problematic for your credibility..
