Description of key information
EC50 ca. 5000 mg/kg soil dry weight (nitrate formation, respiration rate)
NOEC ca. 500 mg/kg soil dry weight (nitrate formation, respiration rate)
Key value for chemical safety assessment
- Short-term EC50 for soil microorganisms:
- 5 000 mg/kg soil dw
- Long-term EC10 or NOEC for soil microorganisms:
- 500 mg/kg soil dw
Additional information
In a soil microflora test, the EC50 was determined to be approximatelx 5000 mg/kg soil dry weight and the NOEC was determined to be approximatel 500 mg/kg soil dry weight. Both endpoints are valid for the nitrate formation rate as well as for the respiration rate.
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.
