Description of key information
Additional information
The substance to be registered represents an UVCB mixture of ‘EDTA metal complexes with cobalt, copper, iron, manganese and zinc’, in which the exact composition can slightly vary. The two main components of the UVCB are EDTA complexes with iron and manganese. Information on the environmental fate of the UVCB is largely based on available information for EDTA (acid form) and a number of its salts (e.g. EDTA-Na4, EDTA-Na2H2, EDTA-CaNa2). A justification for the read-across between these substances and the ‘EDTA metal complexes with cobalt, copper, iron, manganese and zinc’ is provided in a document attached to IUCLID section 13.
The EDTA metal complexes are expected to be resistant to hydrolysis. Neither strong acids nor alkalis cause any hydrolytical reaction of the EDTA molecule. Abiotic degradation by photolysis can be relevant for EDTA metal complexes with iron. Several studies show that Fe(III)-EDTA is photodegraded in natural water. However, the main degradation way of the UVCB will be biodegradation. A large number of biodegradation tests are available for EDTA (acid from) and its salts. These tests show that EDTA is not readily biodegradable under the conditions of standard ready biodegradability tests. It was shown that under special conditions, like adaptation or slightly alkaline pH, which is realistic under environmental surface water conditions, the biodegradability of EDTA is considerable enhanced. Therefore it can be concluded that EDTA is ultimately biodegradable under such environmental conditions.
Bioaccumulation of the ‘EDTA metal complexes with cobalt, copper, iron, manganese and zinc’ is not expected, due to the ionic structure. This confirms a read across study on bioaccumulation in fish (Lepomis macrochirus) with EDTA tetra sodium salt (CAS 64-02-8) as test item. In this study extremely low BCF values in the range of 1 - 2 were determined [Bishop & Maki, 1980].
Due to the ionic structure no adsorption on the organic fraction of soil or sediments is expected. Furthermore, evaporation of the EDTA metal complexes from the water surface into the atmosphere is unlikely. Hence the EDTA metal complexes will preferentially distribute into the compartment water.
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.
