DISCUSSION SESSION ON "ASBESTOS AND TALC" Tuesday, August 3, 1971 - 9:30 A.M. Room 1409, Federal Building #8 200 "C" Street, S.W. Purpose: To specify a laboratory procedure for the determination of asbestos in cosmetic talcum powders which will give consistent, meaning ful results. This may require answers to such questions as: 1. Is there a need to count not only "asbestos fibers" but also "non asbestos fibers" or "fibrous talc"? 2. Is there a need to specify the variety of asbestos: tremolite, chrysotile, anthophyllite, etc,? 3. What particle size ranges should be reported, on the basis on bio logical effects? 4. Should the analytical results reported for "% asbestos" be based on number of particles counted or on percent by weight as estimated from particle areas? 5. Can a similar procedure be used for determining the asbestos content of a variety of foods, drugs, and other products? Format: Brief presentations (about 10 minutes each) on current work and judgments related to the problem, Emphasis on informal discussion and full exchange of information to provide a sound basis for the analytical procedure to be used.
