Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Data waiving:
- other justification
- Justification for data waiving:
- the study does not need to be conducted because a long-term aquatic toxicity study on invertebrates is available
Reference
Description of key information
A long-term toxicity study with aquatic invertebrates with EDTA-CuK2 is available. The results of this long-term daphnia study with EDTA-CuK2 is read across to the target substance EDTA-Cu(NH4)2. A long term test result with the test item is considered to be available in the registration dossier which therefore provides an adequate and reliable coverage of the key parameter(s) of the corresponding OECD TG 211. Based on these considerations, the requirements of Column 2 of Annex VII, Section 9.1.1, second indent are met.

Additional information
Besides to the availability of a long-term test with EDTA-Cu(NH4)2 (read across from source substance EDTA-CuK2), there are two reliable supporting 48h EC50 values for invertebrates available which have been derived from related EDTA complexes, EDTA-FeK, Borrmann, 2007 and EDTA-FeNa, Palmer, 2002, from which the first is based on measured data. This study from Borrman resulted in an 48h EC50 of 100.9 mg/L EDTA-FeNa. Recalculated to EDTA-Cu(NH4)2 this would result in an 48h EC50 of 97.88 mg/L (387.8/399.75 x 100.9). This result is in good agreement with the results observed in the long term daphnia test with EDTA-CuK2.
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.
