	I think catalytic converters produce both sulfuric and
sulfurous oxides. Both of these combine with water in the atmos-
phere to produce strong acids(strong enough to change the pH of
rain and lake water so that the wildlife notices; they're pro-
bably pretty sensitive. I know trout are.) I don't know the
exact way the sulfur in gasoline gets changed into sulfur
oxides but if I had to venture a guess I would say it's
because of the high temperatures in catalytic converters.
Are there any chemists out there to shed some light on the
matter? It's been a while since college chemistry.
