Description of key information

In accordance with column 2 of REACH Annex IX, a long-term toxicity test with fish (required in section 9.1.6) shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on aquatic organisms. Acute toxicity studies with three different trophic levels (algae, daphnia and fish) revealing EC50 values over 100 mg/L, show that the substance is non-toxic to aqueous species. In an available long-term toxicity study with daphnia for the structural analogue substance Fe-EDDHMA-Na, the results of the acute tests are confirmed with an NOAEL of 320 mg/L.  Therefore, no further testing of long-term fish toxicity is needed.
