Description of key information
Under the present conditions, the test results revealed that EC50 of germination and root elongation inhibition rates of the 10 seeds, except cucumber lettuce, carrot and tomato were >589 mg/L (the nominal concentration was 800 mg/L).
Key value for chemical safety assessment
- Short-term EC50 or LC50 for terrestrial plants:
- 589 mg/kg soil dw
Additional information
Under the present conditions, the test results revealed that EC50 of germination and root elongation inhibition rates of the 10 seeds, except cucumber lettuce, carrot and tomato were >589 mg/L (the nominal concentration was 800 mg/L).
The results of definitive test showed that EC50 of tomato in the germination inhibition rate and root elongation inhibition rate under the exposure concentration from 30.8 mg/L to 175 mg/L were 83.2 mg/L and 63.0 mg/L with 95% confidence intervals. There were no germination inhibition effect from 30.8 mg/L to 595 mg/l in cucumber. EC50 of root elongation inhibition was 170 mg/L, with 95% confidence intervals.
EC50 of germination inhibition was 236 mg/L with 95% confidence intervals in lettuce. EC50 of root elongation inhibition was 137 mg/L, with 95% confidence intervals. The germination inhibition and root elongation inhibition rate in carrot were all lower than 50%.
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.
