Additional information
Tests with algae (Desmodesmus subspicatus) revealed the lowest NOEC of 8.2 mg/L. This value is not taken into account for calculation of PNECs, as the test substance is a complexing agent which can dispose micronutrients from the culture medium. Algae growth can be significantly reduced under standardized guideline conditions and may yield apparent results that are more or less severe than the true toxicity (see Guidance on Hazard to the Aquatic Environment Globally Harmonized System GHS Annex 9 A9.3.3.4, 2007). In conclusion PNEC calculation for the aquatic compartment was based on the chronic data from Daphnia magna (NOEC of 320 mg/L).
Conclusion on classification
Based on aquatic toxicity test results obtained, Fe(3Na)EDDHSA is not classified and labelled according to Directive 67/548/EC (DSD) and Regulation 1272/2008/EC (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.
