Le Recueil d'études de cas sur les évaluations des risques des expositions combinées à plusieurs produits chimiques (expositions combinées) peut désormais être consulté sur eChemPortal. À ce jour, il rassemble cinq études de cas de l’Atelier international sur l'évaluation des risques des expositions combinées à plusieurs produits chimiques de l'OMS, l'OCDE et, ILSI / HESI.
La base de données australienne NICNAS Other contient des rapports d'évaluation des risques sur les produits chimiques existants autres que les évaluations prioritaires chimiques existantes.

A guidance document for importing databases into the OECD QSAR Toolbox is now available. The QSAR Toolbox is a software application intended to be used by governments, industry and other stakeholders to fill gaps in (eco)toxicity data needed for assessing the hazards of chemicals. This new document specifically provides guidance on how users can import their own proprietary experimental data into the Toolbox and use them to fill data gaps by read-across or trend analysis.

The Canadian Categorization Results (CCR) and AGRITOX - Base de données sur les substances actives phytopharmaceutiques were recently added as new participating data sources in eChemPortal, the Global Portal to Information on Chemical Substances. eChemPortal provides direct links to collections of information prepared for government chemical review programmes at national, regional, and international levels.

One of the major new features in version 2.1 of the OECD QSAR Toolbox is the availability of estimates of pKa for more than 100000 chemicals. Following an agreement with the company ChemAxon, pKa estimates have been generated with Chemaxon’s pKa calculator and stored in the Toolbox. The availability of these estimates will greatly enhance the potential of the Toolbox to predict the behaviour of chemicals in the environment as well as their effects in animals and humans.

(Quantitative) Structure-Activity Relationships or (Q)SARs are methods for estimating properties of a chemical from its molecular structure. The QSAR Toolbox is a software intended to be used by governments, the chemical industry and other stakeholders to apply (Q)SARs to fill data gaps needed for assessing the hazards of chemicals. This updated version 2.1 contains a number of new functionalities and bug fixes. The release is part of a collaboration between OECD and the European Chemicals Agency.

(Quantitative) Structure-Activity Relationships or (Q)SARs are methods for estimating properties of a chemical from its molecular structure. The QSAR Toolbox is a software intended to be used by governments, the chemical industry and other stakeholders to apply (Q)SARs to fill data gaps needed for assessing the hazards of chemicals. The new version contains many improved tools and databases, especially for the prediction of hazards to human health, and has a more user-friendly interface. The release is part of a collaboration between OECD and the European Chemicals Agency.

The United States Environmental Protection Agency's Aggregated Computational Toxicology Resource (ACToR) has been added as a participant in eChemPortal. ACTor makes links available to more than 400 sources of publicly available data on environmental chemicals. Data includes chemical structure, physico-chemical values, in vitro assay data and in vivo toxicology data. The database contains both tabular, quantitative data as well as links to text reports at other sites.

The first version of the OECD Environmental Risk Assessment Toolkit is now available. This Toolkit describes the work flow of environmental risk assessment and management with links to relevant OECD products that can be used in each step of the work flow. This Toolkit provides support for capacity building to relevant stakeholders by improving the access and use of various tools and guidance on risk assessment and management of chemicals developed under the OECD Environment, Health and Safety Programme.

An internet-based public discussion forum for users of the OECD (Q)SAR Application Toolbox is now available. The (Q)SAR Application Toolbox is a software application intended to be used by governments, industry and other stakeholders to fill gaps in (eco)toxicity data needed for assessing the hazards of chemicals. On this discussion forum, users of the Toolbox can exchange experience with using the software (tips and tricks), seek guidance, exchange databases, exchange user defined profilers and QSARs, and make suggestions for improvements.
