Description of key information

EL50 (48h) = 9.55 mg/L (nominal, WAF) for Daphnia magna (OECD 202)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
9.55 mg/L

Additional information

One study investigating the short-term toxicity of the test substance to aquatic invertebrates is available. The study was performed according to GLP and OECD guideline 202 using Daphnia magna as test organism (Wehrhahn 2010). Loading rate WAFs between 2.5 and 40 mg/L were tested. Analytical monitoring was performed but showed that recovery of test substance was very low using LC-MS analysis. Thus, effects were attributed to the nominal concentration. All validity criteria were fulfilled. The 48h-EL50 value is determined to be 9.55 mg/L based on nominal concentrations.
