Administrative data
Link to relevant study record(s)
Description of key information
From supportive studies, the 14 -d NOEC for aquatic plants exposed to the present test material was 4.22 mg tes item/L in freshwater.
Key value for chemical safety assessment
- EC50 for freshwater plants:
- 121 mg/L
- EC10 or NOEC for freshwater plants:
- 4.22 mg/L
Additional information
Two GLP-studies are available for toxicity to aquatic plants other than algae and both of them were suitable for supporting purpose.
In the first supporting study (1999), the acute toxicity of test material to Lemna gibba was determined in a 14-day semi-static test according to OPPTS 850.4400 guideline.The 14-day NOEC of the test substance was determined to be 4.22 mg test item/L based on the nominal concentrations.
In the second supporting study (2000), the acute toxicity of test material to Lemna gibba was determined in a 14-day semi-static test according to OPPTS 850.4400 guideline. The 14-day NOEC and the ErC50of the test substance were determined to be 59 mg a.s./L and > 121 mg a.s./L, based on the mean measured concentrations, respectively.
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.
