Description of key information
The NOEC for growth rate was 100 mg/L PDTA-H4. Stoichiometric conversion from the PDTA (free acid) to the ammonium iron(III) salt gives a NOEC of 123 mg/L PDTA-FeNH4.
Key value for chemical safety assessment
Additional information
One long-term fish study, valid without restrictions, is available for PDTA-H4 (CAS 1939 -36 -2). The juvenile growth study was performed with Cyprinus carpio for a period of 28 days under semi-static conditions at neutral pH. The NOEC for growth rate was 100 mg/L PDTA-H4. Stoichiometric conversion from the PDTA (free acid) to the ammonium iron(III) salt gives a NOEC of 123 mg/L PDTA-FeNH4.
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.
