This virtual training will discuss the updated Framework for Investigating Asbestos-Contamination at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Sites (released in 2021). By taking this training, participants will learn how to better assess exposure and risk from asbestos and consider unique scientific and technical issues associated with the investigation of human exposure and risk from asbestos.

The training modules will discuss specific strategies that are based on the best currently available science as well as methods for characterizing exposure and risk from asbestos to inform risk-management. The course also presents:A flow diagram for asbestos site assessment and removal action and remedial action decisionsThe application of activity-based sampling (ABS) to evaluate the asbestos exposure potential at a site in support of risk-based removal and remedial decisionsResources for asbestos sample collection and analysisA definition of phase contrast microscopy equivalent (PCME) structures for estimating exposures in asbestos for risk assessmentThe available asbestos toxicity values (non-cancer Reference Concentration [RfC] and age- and duration-specific cancer inhalation unit risks [IURs]) that are used in asbestos risk assessmentA real-world case study that applies the 2021 Framework To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/tio/Asbestos-Framework_041525/
