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 renewal test according to OECD guideline 202, with media renewal after 24 hours. Based on mean measured concentrations, the 48-hour EC50was 6.21 mg test item/L, with 95 % confidence interval of 4.98 to 7.76 mg test item/L. The 48-hour NOEC was 0.655 mg test item/L (2017). The study is a GLP compliant, guideline experimental study available as an unpublished study report.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. Based on geometric mean measured concentrations, the 72-hour EyC50 and EyC10 were calculated to be 6.36 mg test item/L and 1.60 mg test item/L, respectively. The 72-hour ErC50 and ErC10 value were calculated to be > 13.1 mg test item/L and 4.76 mg test item/L, respectively (2016). The study is a GLP compliant, guideline experimental study available as an unpublished report.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.
