Copper creates vertigres, just like brass. Its green and very crystal/power like substance, and its not nessarily harmful as long as you keep it under control. Also, copper can also produce a white corrosion like substance, depending on what kind of liquid is comming into contact with it.

Brazing normally causes smoke from the melting of the filler material and also the coating on the pipe. When the coating burns away it causes a noxious smell and fumes. Don't worry, if you do own a copper core more then likely there is no coasting on it to prevent corrosion; that's where the cross metal plating comes in to play.
I sweat the matter if the copper was in direct heat or absorbing any high temps.
I really need to post something about the various metals, cleaning properties, and corrosion. Murf..
