As the regulatory environment surrounding PFAS continues to evolve, understanding the toxicological basis for regulatory values used in human health risk assessment becomes increasingly important. This webinar will provide a general overview of toxicity values, including cancer slope factors, reference doses, and reference concentrations, and their derivation from various data sources. This detailed presentation will provide a comprehensive overview of key topics, including:


Toxicity Values

· Learn about the sources of toxicity values used to evaluate human health risk, including cancer slope factors, reference doses, and reference concentrations.

· Understand the relationship between toxicity values and screening levels, with specific considerations for PFAS within the CERCLA process.


PFAS Risk Assessment

 · Explore how DoD incorporates Environmental Protection Agency Regional Screening Levels and specific toxicity values in PFAS CERCLA investigations.

 · Address the evaluation of cumulative risk associated with complex mixtures of contaminants such as PFAS, as well as the limitations of such evaluations.


Novel Approaches and Dynamic Regulatory Landscape

· Gain insight into proposed novel approaches for determining PFAS toxicity.

· Discuss potential changes in the dynamic PFAS regulatory landscape. The webinar aims to offer a general understanding of toxicity values, their relevance to human health risk assessments, and current applications for PFAS.
