Reviewing OECD Test Guidelines: pre-evaluation of the general significance of an update need

Applied Ecology /

Fraunhofer ITEM and IME contracted by Umweltbundesamt

OECD Test Guidelines display an important tool to evaluate the impacts of chemicals on the environment. The update of the Test Guidelines is organised by the Working Party of National Coordinators for the OECD Test Guidelines Programme (WNT) and the OECD Secretariat. The procedure relies on proposals from OECD member countries and does not contain a regular update check.


The German Environment Agency contracted Fraunhofer ITEMFraunhofer IME and Ramboll to identify and prioritise any potential update need and to come up with a list for potential actions. It is emphasised that the project shall rely on feedback from the international community. 

An online survey had been conducted in the course of May - July 2021 to collect potential update needs and suggestions. The joint efforts of all of you led to a total number of over 500 individual suggestions. We would like to express our sincerest thanks to you for this impressive feedback.   

In order to work towards a prioritization of the update needs, we would like to share the reported suggestions with you asking you for a pre-evaluation of the general significance of an update need. You can access the survey via:
