Description of key information

96h-LC50 >100 mg/l (sodium ferric EDTA) for a series of invertebrate species

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).
