The OECD webinars on Testing and Assessment Methodologies focus on selected ongoing projects that will result in the short to medium term in new methodologies to test and assess chemicals. These free webinars are open to potential end users among regulators and contract research organisations who want to get familiar with new standards and approaches. Video recordings of our webinars are made available online afterwards.
JOIN THE WEBINAR on adverse outcome pathway (AOP) co-operative activities between scientific journals and the oecd
The OECD is organising a webinar on Adverse Outcome Pathway (AOP) co-operative activities between Scientific journals and the OECD on Tuesday 25 January 2022 from 13:00-14:30 CET / 7:00-8:30 EST.
This webinar is organised primarily for Scientific Journal editors or publishers who are interested in reviewing/publishing AOPs and collaborating with the OECD in this activity.
The main objectives and advantages of such cooperation are to:
- Increase the rate of AOP scientific reviews by distributing the burden of organising and managing those reviews across a broader range of organisations;
- Incentivise more AOP contributions by providing authors with the career recognition associated with a peer-reviewed publication; and
- Benefit participating journals by providing “review-like” articles with high citation potential.
Two scientific journals, ‘Environmental Toxicology and Chemistry (ET&C)’ and ‘Environmental and Molecular Mutagenesis (EMM)’ have been pioneers in this approach and have worked with the OECD to develop an agreement between the Journal and the OECD where the scientific review is conducted in line with the OECD quality standards described in the Guidance Document for the scientific review of AOPs. The first two AOPs that followed that path were accepted by ET&C recently and the corresponding Journal Format Articles are published in a Virtual issue of ET&C called ‘AOP Pathways & Predictions’.
The objective of the webinar will be to present the basis for cooperation between scientific journals and the OECD and discuss the lessons learnt so far. The following presentations will be followed by a Q&A session.
- The AOP framework: Dan Villeneuve (US EPA) will present the AOP framework and challenges being encountered.
- The importance of co-operation: Based on the outcome of a workshop recently held on ‘Science with impact in an era of information overload’, Clemens Wittwehr (EC Joint Research Centre) will focus on the importance of an increased cooperation between all stakeholders in order to promote the application of the AOP framework.
- The OECD AOP review and endorsement process: Nathalie Delrue (OECD Secretariat) will present the OECD AOP review principles and endorsement process and will describe how the cooperation between OECD and scientific journals is formalised in the terms of a Memorandum of Understanding.
- Case study and Lessons learnt from ET&C and EMM: Dries Knapen (University of Antwerp, Belgium) and Jason O’Brien (National Wildlife Research Centre, Canada) will present lessons learnt from the pilot study conducted at Environmental Toxicology and Chemistry (ET&C) and at Environmental and Molecular Mutagenesis (EMM), with the first AOPs and how the journal review process was optimised in this context.

Webinar on Physiologically Based Kinetic (PBK) Models
10 May 2021: Gaining acceptance in next generation PBK modelling approaches for regulatory assessment
The OECD presented the recently published Guidance Document on the Characterisation, Validation and Reporting of Physiologically Based Kinetic (PBK) Models for Regulatory Purposes. This guidance aims to increase the confidence in the use of PBK models parameterised with data derived from in vitro and in silico methods, and help address “unfamiliar” uncertainties associated with these methods.
The webinar introduced the assessment framework for PBK models that was developed to evaluate the attributes and uncertainties of these models, including a dedicated discussion on sensitivity analysis. It also focused on the scientific workflow for characterising and validating PBK models together with a template for documenting PBK models in a systematic manner and a checklist to support model evaluation.
