I wouldn't think you'd have much to worry about. If you made anything you would have heard it popping by now, especially while soldering. :-) The quantities would also be minute.
However, I would, in the future, rinse in water first just to get the etchant down the drain rather than in the trash can, where it can mix with all kinds of other stuff.
Of course, I haven't actually ∗seen∗ your board, so if there are white crystals hanging off of it and/or your quadcopter blows up, it's not my fault. ;-)
