I think you're missing the point.
Some pretty highly qualified people wrote and were referenced in the first one...the second is in broad agreement with that one although got no idea what real qualifications the lady has other than a claimed Bsc.
My only reason in posting the links was to explain better about TEL and put it in some perspective vs the crap that is in ULP.
The catalitic converter stuff I could care less about except the reference to a 'wet' converter which could cope with all the usual stuff + TEL as well is interesting.
Seems to me pretty clear TEL was the lesser of several evils.
Interesting that Thomas Midgie also discovered CFCs...apparently he is pretty close to the top of the Greenies 'most hated' list.
