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.
