Impact/Purpose:

Invited presentation to the 2019 Annual Meeting of the PANWAT (Pacific Northwest) Regional Chapter of the Society of Toxicology in October 2019. This presentation offers a perspective of the current status of non-testing approaches, their evolution in light of the advances in high-throughput approaches and constructs such as adverse outcome pathways.

Description:

Changes in regulations in the industrial chemicals and cosmetics sectors in recent years have prompted a significant number of advances in the development, application, and assessment of non-testing approaches, such as (Q)SARs and read-across. Many efforts have also been undertaken to establish guiding principles for performing read-across within category and analogue approaches. This presentation offers a perspective, as taken from these sectors, of the current status of non-testing approaches, their evolution in light of the advances in high-throughput approaches and constructs such as adverse outcome pathways. The presentation will illustrate these perspectives drawing from 2 main approaches – 1) Exposure based waiving approaches such as the Threshold of Toxicological Concern (TTC) and their utility in risk-based prioritization decision contexts and 2) Read-across approaches – transitioning towards a hybrid harmonized objective read-across workflow and the application of chemical grouping approaches to identify and evaluate PFAS (per and polyfluorinated substances) toxicities. This abstract does not necessarily represent U.S. EPA policy.
