    A new guidance is now available to facilitate the ecological risk assessment of organometallic and organic metal salt substances

    The OECD has published guidance to facilitate the ecological risk assessment of organometallic and organic metal salt substances. A strategy is presented based on key steps that first consider the fate of these substances in the environment, the identification of moieties of concern, and subsequently the selection of an appropriate path forward to either assess the inorganic moiety and/or the individual substance.

    Report of the pilot exercise on classifications for selected chemicals assessed at CoCAM

    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.

    Report on OECD Workshop on Children’s exposure to chemicals

    This document presents the results of the workshop on children’s exposure to chemicals on 7-8 October 2013 in Utrecht, the Netherlands. The main outcomes are 1) a decision tree to enable risk assessors to decide when they should perform children specific exposure and risk assessment, and 2) recommendations for further work on specific exposure assessment issues.

    Guidance on grouping of chemicals, second edition

    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.

    Harmonised method for characterising oleochemical substances for assessment purposes.

    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.
