Description of key information
Ewell (1986) evaluated the toxicity of EDTA-FeNa to three different benthic invertebrates Gammarus fasciatusis a freshwater benthic amphipod, Lumbriculus variegaties an endobenthic oligochaete and Asellus intermedius a macrobenthic isopod and no effects were observed upto 100 mg/L. According to Di Toro aquatic organisms are equaly sensitive as benthic organisms. The results from Ewell are indeed in good agreement with what has been observed for aquatic organisms (also by Ewell). Because of the negligible sorption potential of EDTA-metal complexes no accumulation of these complexes will occur in sediment. The risk for organisms living in the benthic compartment will therefore be equal to that of the aquatic compartment.

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.
