Description of key information

The No Observed Effect Concentration (NOEC) of test item to aquatic micro-organisms is 20 mg test item/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
20 mg/L

Additional information

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 (2015). The study is considered reliable and relevant for use for this endpoint. The No Observed Effect Concentration (NOEC) of test item to aquatic micro-organisms is 20 mg test item/L.
