Popis: This study's objective is to assess the risk of asbestos-related disease being contracted by past users of cosmetic talcum powder. To our knowledge, no risk assessment studies using exposure data from historical exposures or chamber simulations have been published. We conducted activity-based sampling with cosmetic talcum powder samples from five opened and previously used containers that are believed to have been first manufactured and sold in the 1960s and 1970s. These samples had been subject to conflicting claims of asbestos content; samples with the highest claimed asbestos content were tested. The tests were conducted in simulated-bathroom controlled chambers with volunteers who were talc users. Air sampling filters were prepared by direct preparation techniques and analyzed by phase contrast microscopy (PCM), transmission electron microscopy (TEM) with energy-dispersive x-ray (EDX) spectra, and selective area diffraction (SAED). TEM analysis for asbestos resulted in no confirmed asbestos fibers and only a single fiber classified as "ambiguous." Hypothetical treatment of this fiber as if it were asbestos yields a risk of 9.6 × 10
