Workshop Report no.41- Overcoming challenges and advancing (bio)degradation guidelines: OECD TG309 revisited

In a Nutshell

The OECD Test Guideline (TG) 309, designed to assess the degradation of chemicals in aerobic surface water, has become increasingly important in regulatory frameworks, especially within the EU. As its use grows, so do concerns about its robustness, practical implementation, and environmental relevance. In response, ECETOC convened a 1.5-day workshop bringing together in-person and online participants from industry, academia, regulatory bodies, and contract research organizations to address these challenges.
