Description of key information
262 individual data points from 5 standard species (Oncorhynchus mykiss, Pimephales promelas, Lepomis macrochirus, Brachydanio rerio and Cyprinus carpio) were selected for the assessment of short-term toxicity to fish.
Key value for chemical safety assessment
Additional information
Data are available on a number of substances containing inorganic copper and read-across is justified on the basis that for the purposes of assessing the ecotoxicology of Copper (II) pyrophosphate (copper(2+) diphosphate) the chemical species of interest is copper. As such studies referring to soluble copper ions from any source are considered to be directly relevant to Copper (II) pyrophosphate. Copper (II) pyrophosphate is considered to contribute to copper toxicity in the environment and as such the data assessment and risk assessment focusses on the copper ion as the phosphate ion is not considered to be toxic.
A voluntary risk assessment report of copper and copper compounds has been submitted to the European Chemicals Agency by the European Copper Institute (June 2008). This report is based on the industry initiative to perform a voluntary risk assessment on a substance according to the mechanisms of the implementation of the Existing Substance Regulation (EEC) No 793/93 (ESR). The procedure was agreed by the 11th Joint Meeting of the Competent Authorities for the Implementation of Directive 67/548/EEC and ESR Regulation. Italy has been acting as a reviewing Member State for the substance and the risk assessment report has been reviewed by the Technical Committee on New and Existing Substances (TC NES) according to standard operational procedures of the Committee.
In accordance with the above mentioned European copper risk assessment, the environmental hazard assessment is based on tests carried out with soluble copper species. Studies reporting quantitative dose responses of Cu(II) ions, delivered from soluble copper compounds to aquatic organisms are used for this assessment.
The data presented are considered to be adequate and reliable for the purpose of defining an appropriate classification for the ecotoxicity of Copper (II) pyrophosphate in accordance with Regulation (EC) No.1272/2008 (EU CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
