the study does not need to be conducted because direct and indirect exposure of soil is unlikely

Description of key information

In accordance with column 2 of REACH Annex IX, soil simulation testing (required in section 9.2.1.3) does not need to be conducted as FeNa-EDDHA has no high potential for adsorption to soil based on the calculated Koc of 0.12 (estimated with the Kow method, KOCWIN v2.00). Together with its high water solubility (≥ 15.0 g/100g < 20.3 g/100g) the substance is expected to be very mobile in the aqueous phase and will not absorb to sediment and soil. In addition, it could be shown in read across studies with Fe-EDDHMA-Na and Fe-EDDHMA-K that the substance is subject to photolytical degradation. In conclusion, is can be expected that FeNaEDDHA will be rapidly degraded photolytically. Therefore, no further soil simulation testing is needed to assess whether the substance is persistent in the environment or not.
