Analysis of the ecotoxicity data submitted within the framework of the REACH Regulation. Part 1. General overview and data availability for the first registration deadline

REACH(1) entered into force in June 2007 and has hence been operational for six years. With the first registration deadline in November 2010, the European Chemicals Agency (ECHA(2)) has received a large amount of scientific and administrative information related to chemical substances. In order to understand what type of data on ecotoxicity endpoints was submitted under the REACH framework a detailed analysis of the availability and content of relevant information was performed. To avoid unnecessary testing, the REACH Regulation provides registrants with the possibility to build testing strategies and to adopt the standard information requirements based on the specific conditions listed in the regulation. The types of information submitted by registrants to fulfil data requirements for aquatic, sediment and terrestrial toxicity endpoints were analysed. The REACH database analysis confirms large differences in the availability of experimental aquatic versus sediment and soil ecotoxicity data. Information requirements on aquatic organisms are mainly covered by experimental data, while those for sediment and soil are mostly waived. (C) 2013 Elsevier B.V. All rights reserved.
