EC50 (24h) = 1.2 [1.1-1.4] mg/L - Validity criteria fulfilled:
- yes
- Conclusions:
- No mortality was observed during the studyand an EC10 (48h) and EC50 (48h) > 30.1 mg/L (geom. mean) were determined.
- Executive summary:
A Daphnia sp. acute immobilisation test (according to OECD Guideline no. 202) and following was conducted applying daphnids <24h old. The study was conducted according to GLP.
Concentrations were not within 20% of the nominal concentration throughout the study. And endpoints are thus reported as geometric mean concentrations (geo. mean conc.)
Organisms were exposed to the test item for 48h and since no mortality was observed during the study an EC10 and EC50 (48h) > 30.1 mg/L (geom. mean) were determined.
