Recent litigation alleges talc exposure can cause both asbestos-related diseases (e.g., mesothelioma) and ovarian cancer. Occupational exposures occur during mining and processing operations; consumer exposures occur during use of products containing industrial-grade or cosmetic-grade talc. Talc's geological attributes, structural characteristics, and anticipated impurities will be discussed. We will clarify exposure profiles to talc associated respirable particles by explaining the fiber/cleavage fragment controversy and relate those exposure profiles to alleged asbestos-related diseases. We will review human and animal studies to demonstrate to date, exposure assessments and scientific studies do not support a causal role between talc and ovarian cancer.
Upon completion of this presentation, attendees should be able to:
• Identify the chemical and physical characteristics of mined talc.
• Recognize why fibers and cleavage fragments are important in exposure assessments.
• Describe the physical particle characteristics of inhalable talc.
