Endpoint summary
Administrative data
Description of key information
Aquatic toxicity endpoints are based on test data following standard guidelines. All data are therefore considered to be reliable and relevant for the endpoint concerned.
Short-term toxicity to aquatic invertebrates
The acute toxicity of the test item to Daphnia Magna was determined in a static test according to OECD guideline 202 (2003). Dilutions of a saturated solution were tested with analysis based on DOC. The 48 h EC50 value for Daphnia Magna immobilisation is 7.98 mg/L and the 48 h EC10 is 5.69 mg/L (2003). The study is a GLP compliant, guideline experimental study available as an unpublished study report. There are no restrictions and the study is fully adequate for assessment.
Toxicity to aquatic algae and cyanobacteria
The toxicity of the test item to the green algae Pseudokirchneriella subcapitata was determined in a study according to OECD guideline 201 (2017). Based on initial measured concentrations, the 72-hour EyC50 and EyC10 for the test item were calculated to be 3.37 mg test item/L and 1.71 mg test item/L, respectively. The 72 -hour ErC50and ErC10values were calculated to be 13.8 mg test item/L and 2.78 mg test item/L, respectively. The study is a GLP compliant, guideline experimental study available as an unpublished report. There are no restrictions and it is fully adequate for assessment.
Additional information
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.
