Nope. Just water and carbon dioxide.
Sulfur dioxide has a very pungent odor, otherwise known as 'rotten egg gas'. Aircraft don't use it or emit it.
Aluminum dust is too dangerous. It is not allowed on board aircraft in any form. If someone were stupid enough to spray that stuff into the air, it would produce a very bright light just before it destroys said aircraft.
Barium is even more dangerous. Only an idiot would spray barium or aluminum from an airplane.
