Hell, the silica sounds nasty enough on it's own, that stuff is why potters get so fanatical about keeping clay dust cleaned up. It'll do a perfectly good job of messing up your lungs if the particles are the right size, re, nanoparticles... Me, I suspect the manufacturer never did any real testing of the stuff. 80 people immediately becoming sick is something that would have been probably been caught in animal testing for one... That or what was produced was different then what was tested due to manufacturing errors, quiet possible too if it's a novel process. Anyway, what you want to worry about with nano-tech is the weird effects that'll show up *much later* That's why we produced so much DDT before it was banned... -- pete@petertodd.ca http://www.petertodd.ca -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
