The OECD has published the second edition of the guidance on grouping of chemicals. This edition has been augmented with experience and examples encountered in the OECD Cooperative Chemicals Assessment Programme. It also introduces new or revised guidance on elaborating the analogue and category approach, quantitative and qualitative read-across, justifying read-across, and using bioprofiling results for grouping chemicals.

The OECD has published a guidance for characterising oleochemical substances. The method presented gives guidance on how these complex substances can be characterised in a way that their composition is accurately and consistently reflected to ensure that substances with the same chemical composition, manufactured in different countries, can be characterised with the same description for hazard assessment purposes.

The Gefahrstoffdatenbank der Länder, a german database, is now linked to eChemPortal. 102545 substance records can be searched through the substance search. This includes German hazardous substances legislation as well as other sources reflecting the state of technology and occupational health and safety relating to activities involving hazardous substances. In addition, it contains links to various other German data bases.

This guidance document intends to provide an insight into which pieces of information that are necessary to identify and document an adverse outcome pathway (AOP) and how to present them. The AOP concept has been developed as a means of providing transparent mechanistic justification and weight-of-evidence to reduce uncertainty in the predictions for complex toxicological endpoints.

30/01/2013 – Recently the OECD release the third generation of the QSAR Toolbox. The existing tutorials and videos have now been updated according to the new version of the QSAR Toolbox to help the user building categories that are mechanistically and structurally robust to maximise success in filling data gaps for the endpoint of interest. Mid next year the OECD is planning to release additional training material.
