What are the concentrations of ozone-destroying chemicals as a function of time ?

I've got more graphs if you want them. Scan up the discussion to the graphics I already posted; the "Stratospheric Ozone: An Electronic Textbook" link has more.

Thanks -- I had only seen one graph, but without time scale. The Electronic Textbook looks interesting from a quick scan of a few screens -- will save for more review.
