Description of key information
The invertebrate (including arthropods) effect records include 108 NOEC/(L(E)C10 values; hard and soft bodied organisms with different exposure routes and feeding strategies belonging to 10 different species and 6 different families.The NOECs are carried forward to the risk characterisation.
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.
NOECs for soil macroorganisms and terrestrial arthropodes:
The invertebrate (including arthropods) effect records include 108 NOEC/(L(E)C10 values; hard and soft bodied organisms with different exposure routes and feeding strategies belonging to 10 different species and 6 different families (i.e. the Eisenia andrei, Eisenia fetida, Lumbricus rubellus belonging to the family of the Lumbricidae; Cognettia sphagnetorum to the family of the Enchytraedae; Isotoma viridis, Folsomia candida, Folsomia fimetaria to the family of the Isotomidae; Hypoaspis aculeifer to the family of the Laelapidae, Platynothrus peltifer to the family of the Camisiidae, Plectus acuminatus to the family of the Plectidae).
Individual high quality NOEC/(L(E)C10 values from different studies range from 8.4 mg/kg for Eisenia andreicoco on production to 1,460 mg/kg for Folsomia candida reproduction.
Remarkably low NOEC values are found in some tests that used Eisenia species (E. fetida and E. andrei). The lowest value is found for E. Andreire production (8.4 mg total Cu/kg) in a natural soil (a German standard soil often used in toxicity tests, LUFA 2.2). This value is below the limit for essentiality. Van Gestel et al, 1989 actually warn against use of cocoon production as reliable endpoint for Eisena Feitida.
Important intra-species variability in NOEC/L(E)C10 values are observed due to differences in the physico-chemistry of the soils. For invertebrates, 2 models were developed: the E. fetida model, representing soft-bodied species and the F. candida model representing hard-bodied species. These models were used for the normalization of the invertebrate NOEC data and the derivation of the PNEC.
Records are available on the influence of soil ageing/leaching on the plant toxicity, especially those reported by Ma et al, 2006a and Ma et al, 2006b (see section adsorption/desorption) are also of relevance to the terrestrial PNEC. This information was used for the PNEC derivation relevant to monitoring data.
Additional information:
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 11thJoint 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.
