Endpoint summary
Administrative data
Description of key information
Experimental data for the following ecotoxicological endpoints are available. All data are considered to be reliable and relevant for the endpoint concerned.
Short-term toxicity to fish
The 96-hour LC50 was > 1.38 mg/L (geometric mean measured test item concentration). The acute toxicity of the test item to zebrafish was determined according to the principles of the OECD Guideline 203 and was GLP-compliant.
Short-term toxicity to aquatic invertebrates
The 48-hour EC50 for immobilisation of Daphnia was determined to be 7.9 mg/L. The study was conducted according to OECD guideline 202 and was GLP-compliant.
Toxicity to aquatic algae and cyanobacteria
The 72-hour EC10 and EC50 for growth rate were determined to be 3.53 mg/L and 5.57 mg/L, respectively (Scheerbaum 2015). This study was conducted according to OECD guideline 201 and was GLP-compliant.
Toxicity to microorganisms
The NOEC of test item to aquatic micro-organisms is 29.3mg/L. The toxicity of the test item to activated sewage sludge was taken from the toxicity control of a GLP-compliant ready biodegradability closed bottle test following OECD guideline 301B.
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.
