20 Nov 2009, 3:21 PM | Re: cant find answer OK, I just types CFC replacement into Google and came up with: http://www.fluorocarbons.org/documen...s/PFCs/cfc.pdf substitutes for CFCs CFC replacement efforts are paying off, as buildup of chemicals slows, says NOAA. - Free Online Library Potential accumulation of a CFC-replacement degradation product in seasonal wetlands I'm sure you can form an opinion with facts to base them on from that. I would be careful to investigate the negative effects of the replacements as well, to balance your discussion.
