Advancing the science, practice, and policy of alternatives assessment and informed substitution

A4 Webinar Series: How to Get to Safer Alternatives Using Non-Animal Testing Methods




Occurred on: Wednesday, January 29, 2020



Experts who conduct alternatives assessment often face the serious challenge of how to adequately characterize a hazard when critical toxicity data are missing for a specific chemical. To solve this problem, interest is growing around the application of new approach methods (NAMs), utilizing non-animal tests as an effective means to fill these data gaps. Over the last decade, significant investments have been made in the development of NAMs. However, are these methods ready for use in alternative assessments? Are there alternative test methods that can be reliably used to fill certain hazard data gaps in both informed substitution and product development contexts? If so, for what endpoints? What are some of the current strategies being used to incorporate NAMs into chemical hazard assessments? The Association for the Advancement of Alternatives Assessment’s (A4) winter 2020 webinar, How to Get to Safer Alternatives Using Non-Animal Testing Methods will explore these questions and more. Please join us.

Green Chemistry & Chemical Stewardship Online Certificate Program

This certification program is endorsed by the Association for the Advancement of Alternatives Assessment.




Course III: Register by March 21, 2020





This 3-course program is intended to give graduates the tools to make a difference and find success by learning to design safer chemicals and industrial processes. Businesses are facing increasing market and regulatory pressures to use less toxic chemicals in their manufacturing processes and products, and are in need of professionals who can provide innovative solutions and more sustainable substitutes.
