The OECD has published a report on a pilot chemical classification exercise undertaken in 2013 and ‘14. Using a number of chemical assessments agreed in the OECD hazard assessment programme, reasons why classification proposals may differ were investigated. The report concludes on the main reasons for such differences, and recommends some measures to overcome some of them.

The OECD Advisory Group on Endocrine Disrupters Testing and Assessment met on 16-17 October 2014 in Paris to discuss the development and update of Test Guidelines and related documents for endocrine disrupters testing and assessment.

PRTR have been established throughout the world to track releases and transfers of potentially harmful chemicals. But most of the PRTR systems were designed without considering comparability, each PRTR has its own requirement of reporting chemicals and sectors. To harmonise globally, OECD reviewed the reporting chemicals and sectors across PRTR systems and produced proposal for harmonised lists of reporting pollutants.

OECD countries have developed PRTR system to track releases and transfers of potentially harmful chemicals. To improve PRTR system, OECD have analysed common elements (pollutants, sectors) in different PRTR systems, mainly focus on institutional arrangement. This serves as a common framework for different PRTR system, and supporting materials for a country that intends to develop or update its PRTR.

This guidance is intended to harmonise the way non-guideline in vitro test methods are described. This should in future facilitate an assessment of the relevance of test methods for biological activities and responses of interest, of the quality of data produced, irrespective of whether these tests are based on manual protocols or assay protocols adapted for use on automated platforms or high-throughput screening systems (HTS).

The OECD has just published two new Test Guidelines on human health hazard endpoint skin sensitisation. Skin sensitisation refers to an allergic response following skin contact with the tested chemical, as defined by the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS).

A set of new and updated OECD Test Guidelines was published at the end of July 2015 to test chemicals and identify hazards such as endocrine disruption, serious eye damage, genotoxicity, skin irritation or corrosion.

This document provides background information on activities related to manufactured nanomaterials, as well as other activities on nanotechnologies at the international level. The information provided in this document captures OECD activities between February and December 2013.

The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. Every year new and updated Test Guidelines are adopted to meet the regulatory needs in OECD member countries. The most recent Test Guidelines were adopted in July 2016.

Participants from 15 countries attended the Workshop on Developmental Neurotoxicity: The use of non-animal test methods for regulatory purposes” on 18 October 2016, in Belgium. The event, co-organised by the OECD and the European Food Safety Authority (EFSA), focused on opportunities and challenges related to alternative methods for testing and assessing the DNT potential of chemicals.

Results of a joint pilot project of the OECD and the UN Sub-Committee of Exports on the Globally Harmonised System of Classification and Labelling of Chemicals (UNSCEGHS) including a report of the results of the pilot and non-biding proposed classifications for three substances.

This new council act recommends that Member countries take steps to establish, as appropriate, implement and make publicly available a pollutant release and transfer register (PRTR) system using the principles and information set forth in the OECD Guidance Documents on PRTRs.

This guidance document was originally published in 2012 and updated in 2018 to reflect new and updated OECD test guidelines, as well as reflect on scientific advances in the use of test methods and assessment of the endocrine activity of chemicals. The document is intended to provide guidance for evaluating chemical using standardised test guidelines.

The Product Release and Exposure Data Warehouse is a Microsoft® Access 2016 database is designed to house existing data on releases of chemicals from, and exposures to, commercial and consumer end products. A number of forms provide a simple approach to data entry and access to the existing data.

GHSTS is a standardised set of technical specifications for assembling electronic files for pesticide registration in a predefined manner. Once assembled according to the GHSTS, the dossier files can be transferred from a business to a regulatory authority and can be used in a regulatory process. Version 2.0 includes improved lifecycle management of documents over a series of submissions for one pesticide (or other) regulatory action.
