Message-ID: <266@pyuxss.UUCP> Date: Fri, 3-Feb-84 09:25:10 EST Article-I.D.: pyuxss.266 Posted: Fri Feb 3 09:25:10 1984 Date-Received: Wed, 8-Feb-84 03:52:43 EST References: <355@ihuxa.UUCP> Organization: Central Services Org., Piscataway N.J. Lines: 13 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. Sharon Badian
