That's part of the problem with this topic.

How do you know that the chemicals are being dispersed through jet fuel exhaust? Other speculation has been through easily installed disbursement nozzles on the wingtips.

Evidence to support is helpful, like schematics, documentation, official memos, emails, FOIA docs, testimony from engineers, etc.

A good start would be to provide foundational research, such as the standard composition of Jet A and Jet A-1, along with JP-8, JP-5 and even Avgas, 100LL and variants.

From there you could expand (with evidence) how contaminants are handled, and what the impact on engines would be, to see if it would even be possible or would ruin engines.

I'm quite sure there is already documentation on this topic researched and published by any number of agencies, just waiting to be sourced.
