Well, I tried to send a bunch of e-mail messages earlier (before I had to leave for class), but I got an error message every time I tried to send anything, and then it got to the point where it wouldn't even let me download incoming mail, so I gave up and went to class with a bunch of messages waiting unsent in my outbox. Apparently ATT fixed whatever the problem was while I was away, because it seems to be working correctly now (and I had 180 new incoming messages waiting when I got back) . . . --- Ronn!Blankenship [EMAIL PROTECTED] wrote: Deborah Harrell wrote: Apparently we've inadvertantly helped develop a bacterium that needs our waste to live: http://story.news.yahoo.com/news?tmpl=storyu=/ap/20030703/ap_on_sc/toxic _feeder_5 ...Vinyl chloride is one of the most common and hazardous industrial chemicals.

Yeah, it was memorable . . . and that is _not_ a compliment . . . Funny how 'monsters' can be both huge flesh-eating creatures, and - microscopic flesh-destroying ones. Though I guess to be precise the microorganism described in the article feeds on vinyl chloride monomer, not the polymer.

Scouted: Vinyl Chloride Eater
Apparently we've inadvertantly helped develop a bacterium that needs our waste to live: http://story.news.yahoo.com/news?tmpl=storyu=/ap/20030703/ap_on_sc/toxic_feeder_5 ...Vinyl chloride is one of the most common and hazardous industrial chemicals.

Brief contact with vinyl chloride can cause dizziness, drowsiness and headaches. Long-term exposure can raise the risk of a rare form of liver cancer, according to the EPA.
