Description of key information
96h-LC50 >100 mg/L (sodium ferric EDTA) for a series of invertebrate species, hence similar for FeK-EDTA.
Additional information
The acute toxicity (96h-LC50) of sodium ferric EDTA towards a range of invertebrate species was investigated in a multispecies test according to EPA-600/3 -75 -009 and ASTM method E729 -80 (Ewell et al 1986). The following species were tested:
Asellus intermedius (pillbug), Daphnia magna (water flea), Dugesia tigrina (flatworm), Gammarus fasciatus (sideswimmer), Helisoma trivolvis (snail), Lumbriculus variegatus (segmented worm) and Pimiphales promelas (fathead minnow).
The 96h-LC50 was found to be >100 mg/L for all test species except for Daphnia magna, where it was 32 mg/L (see separate entry IUCLID 6.1.3).
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.
