Description of key information

EC50 (3h) > 1000 mg/L, EC10 (3h) = 260.1 mg/L (nominal) for activated sludge (OECD 209)

Key value for chemical safety assessment

EC50 or LC50 for microorganisms:
1 000 mg/L
EC10, LC10 or NOEC for microorganisms:
260.1 mg/L

Additional information

One study investigating the toxicity of the test substance to aquatic microorganisms is available. The study was performed according to GLP and OECD guideline 209 (Wehrhahn 2010). In a static study domestic activated sludge was exposed for 3h. The test material was applied directly to the test vessels. Analytical monitoring was not performed. All validity criteria were fulfilled. The 3h-EC50 is determined to be > 1000 mg/L, while the respective 3h-EC10 value is determined to be 260.1 mg/L based on the nominal concentration.
