Risk Assessment for Asbestos and Other Fibrous Materials: Learning from the Past, Looking into the Future

Thursday, May 26 | 8:00 AM – 12:00 PM

Topics:

Risk Assessment and Management, Toxicology

Arranger: A. Korchevskiy, Chemistry & Industrial Hygiene, Inc., Wheat Ridge, CO. Moderator: B.Case, McGill University, Montreal, QC, Canada. Monitors: D. Hall and R. Strode, Chemistry & Industrial Hygiene, Inc., Wheat Ridge, CO.

Continuing the tradition of addressing outstanding issues of asbestos risk assessment with distinguished industrial hygienists, toxicologists and mathematicians from multiple countries and disciplines, this session will help to keep industrial hygienists current with new developments in asbestos exposure science and risk assessment methodologies include new analytical methods for asbestos testing, new types of potentially dangerous fibrous materials including zeolites and various amphibole fibers, and advances in toxicology for fibrous materials.
