Copper oxidizes, as a result it's always releasing something from a molecular level. Then there's the solder and flux from the solder. I'm no expert by any means, but this is pushing a gas into people.
As far as I'm aware, copper has pretty strong antimicrobial properties. It doesn't appear as if those pipes have been soldered together either. It looks like to me that they use pipe thread and pipe thread tape to assemble everything.

Yes, and the CV has the shortest lifespan on copper. Pretty sure that's why it was used.
