This webinar will be hosted by the EPA Superfund Technical Review Workgroup (TRW) Lead Committee to assist Superfund and RCRA Corrective Action risk assessors in the use of the Integrated Exposure Uptake Biokinetic (IEUBK) Model for Lead in Children, the Adult Lead Methodology (ALM), and the All-Ages Lead Model (AALM) in lead human health risk assessment. The first day will provide an overview of all three models and their uses in lead risk assessment, followed by hands-on IEUBK exercises, including running the model, deriving preliminary remediation goals (PRGs), and using site-specific bioavailability information. The second day will be additional interactive (optional; attendees may also listen and follow along), technically-driven instruction on using batch mode and evaluating intermittent exposure in the IEUBK model, an exercise using the ALM, and a demonstration of the AALM, including an intermittent exposure example, and comparison of the AALM to the IEUBK. These sessions will provide opportunities to learn the intricacies of Pb human health risk assessment and hands-on demonstrations. It is encouraged to download the models prior to the training sessions (see Webinar Slides and References for more information).
