Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
NOEC: 84 mg/kg dry weight based on read-across from EDTA. Expressed as HEDTA-H3 this would be 69 mg/kg soil dw
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 69 mg/kg soil dw
Additional information
Two tests were available for review for toxicity of EDTA to terrestrial plants. Both tests were considered generally acceptable for review (Klimish rating 2). Evanelou et al (2006) reported on the effects of Na2EDTA on vegetative vigour of plants following application in a laboratory test on Nicotiana tabacum. The test had an inhibitory effect on growth of the tested species at rates of 420 mg/kg. The overall NOEC was determined to be 84 mg/kg. Geebelen et al (2002) reported on the effects of Pb-EDTA and EDTA on oxidative stress reactions and mineral uptake in Phaseolus vulgaris. Results indicated that a 14 day exposure test showed no inhibitory effect on seedling emergence and growth of the test species up to a concentration of 58.4 mg/kg soil.
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.
