Dave, The literature indicates that the smaller the particle, the more dangerous it may be due to larger surface area/volume ratio.
My guess is that these are the hardest to remove from circulating air. - probably it's better to keep them in a confined chamber when preparing a colloid. I am not sure whether they penetrate skin. -- Lou Pagnucco Dave Roberson wrote: > In an emergency situation can a strong magnet pull most of these from the > room air?
