Description of key information
Due to the ionic structure no adsorption onto the organic fraction of soil or sediments is expected
Key value for chemical safety assessment
Additional information
Due to the ionic structure under environmental relevant pH conditions, no adsorption onto the organic fraction of soil or sediments is expected [EU Risk Assessment, 2004]. This are confirmed by experimental results where EDTA was almost entirely present in the form of negatively-charged complexes with alkaline earth and trace metals, and neither of these complexes nor the free or protonated ligand itself could have been significantly adsorbedon the surfaces of the solids [Gardiner, 1976]. Further on, it is confirmed due to the low log Pow of -3.86. in accordance with column 2 of REACH Annex VIII, a Adsoprtions-/Desporptions-Screening test (required in section 9.3.1) does not need to be conducted.
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.
