Overcoming challenges and advancing (bio)degradation guidelines: OECD TG309 revisited

21-22 January 2025

The Hotel, Brussels

 The OECD 309 test guideline (Aerobic Mineralisation in Surface Water), last updated in April 2004, plays a pivotal role in understanding the environmental fate of chemicals and is generally the first test requested under REACH for non-readily biodegradable substances. Given the anticipated update in the OECD work programme, this workshop aims to unite experts in environmental chemistry, toxicology, and regulatory science to discuss the improvement of the guideline.

This workshop will focus on:

• Discussing and addressing current challenges and limitations in conducting and interpreting degradation simulation studies.
• Defining and aligning on the key updates needed for the OECD 309 guideline.
• Establishing a roadmap to ensure that prioritized updates are addressed in time for the OECD 309 TG update.
• Identifying research needs and potential methodological advancements to enhance the relevance and applicability of this and other guidelines.
