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 V7ill 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 foo.ds, 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.
