REACH baseline study 10 years update : monitoring REACH with the risk & quality indicator system

This executive summary presents the main findings of the 10 Years Update of the REACH Baseline Study. The REACH Baseline Study aims to monitor the effectiveness of REACH as regards risk reduction and improvement of the quality of data available for the assessment of chemicals. In 2006, before REACH entered into force, a methodology was established to derive the following indicator values for a set of 237 reference substances that can be considered representative of the chemicals available in the EU market: - a Risk Score, which indicates the risk posed by a substance, and - a Quality Score, which indicates the quality of the data available to assess the risk associated with a substance. After 5 years, the assessment has been repeated for the substances which had been registered by August 2011. This 5 Years Update (5YU) allowed to detect changes in the nominal risk of the reference substances and in the quality of their data, which are likely to be due to the first registration phase (by 30 November 2010). The 5YU (EUROSTAT 2012) contributed to the REACH review in 2012. The 10 Years Update (10YU) presented in this report analyses changes in the Risk Scores and Quality Scores based on registrations until September 2015, including registrations from the second registration phase (by May 2013) as well as updates from dossiers registered previously. In close cooperation with ECHA, confidential data from the relevant registration dossiers were assessed for this purpose. In addition, the 10YU analyses some impacts of substance evaluation, dossier evaluation and additional measures of ECHA.
