Additional information
There are no available studies on the long term toxicity of exposure to HEDTA to Fish. Read-across to EDTA is considered appropriate based on similar ionisation potentials for EDTA and HEDTA. Long-term toxicity of CaNa2EDTA on freshwater fish was measured in an early life study with Brachydanio rerio (BASF, 2001). Results indicated a NOEC of equal or greater than 25.7 mg/L after 35 days exposure .
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.
