Description of key information

Additional information

Ecotoxicological endpoints are completed for the test item based on test data following standard guidelines. All data are considered to be reliable and relevant for the endpoint concerned.

Short-term toxicity to fish

The 96-hour LC50 was 14.1 (10.0 - 20.0) mg/L (nominal test item concentration, Scheerbaum 2016). The acute toxicity of the test item to zebrafish was determined according to the principles of the OECD Guideline 203 and EU Method C.1 and was GLP-compliant.

Short-term toxicity to aquatic invertebrates

The 48-hour EC50 for immobilisation of Daphnia was determined to be 25.5 mg/L (Noack 2015). The study was conducted with the test item according to OECD guideline 202 and EU C.2 method and was GLP-compliant.

Toxicity to aquatic algae and cyanobacteria

The 72-hour EC10 and EC50 for growth rate were determined to be 22.7 mg/L and 41.3 mg/L, respectively (Scheerbaum 2015). This study was conducted according to a standard method and was GLP-compliant.

Toxicity to microorganisms

The NOEC of test item to aquatic micro-organisms is 20 mg/L. The toxicity of the test item to activated sewage sludge was taken from the toxicity control of a GLP-compliant ready biodegradability Manometric Respirometry test following OECD guideline 301F (Maischak 2015). The study is considered reliable and relevant for use for this endpoint.
