Georg Fuell #1 / 4	DiCHLORO-diFLOURO-METHANE: HOW DANGEROUS ?????? ***************************************************** 1.35 ppb DiCHLORO-diFLOURO-METHANE have been found in the air of a colleague's workplace (ca. 20 square meters), where he is working for 12 months now. No Lab work has been done in this room since Dec 1992, so the concentration may have been higher when he started. However, 2 computers are operated in the room since '93. *************************************************** I'd like to know whether there is any danger associated with this chemical, and what symptoms it may cause (if any). Also, can anybody estimate its concentration one year ago ? THANKS A LOT FOR YOUR REPLY !!!! POINTERS TO OTHER RESOURCES ARE WELCOME !!!! ***************************************************** thank you for your attention, georg The convex hull of all disclaimers made on usenet last year applies to this mess

In addition, it is famous for its contribution to the stratospheric ozone depletion. Also in this respect it should be considered to be not wealthy. Manuel

The level you mentioned, 1.5 ppb, is too small to be of any interest or impact. This material is a common refrigerant. It has been described as being "one of extraordinarily low toxicity, presenting very little practical hazard" (Industrial Hygiene and Toxicology, D. D. Irish, 1963). Animals can acutally live in an atmosphere of 20%, with no effects.
