Description of key information
In the table below the acute aquatic toxicity data are summarised
| Species | Guideline | Result in mg/l | Remarks |
Pseudokirchneriella subcapitata |
OECD TG 201 |
EC50 growth rate > 0.31 based on geometric mean measured concentrations |
Key study, Rel. 1. No robust EC10-value could be determined for growth rate. The ErC50 is >0.31 mg/L based on the fact that only 21% inhibition of growth rate was observed at this concentration. |
Daphnia magna |
OECD TG 202 |
EC50 48h = 0.33 based on mean measured concentrations |
Key study, Rel 1. |
Additional information
In the study with algae, the geometric mean measured concentrations showed no dose-response curve due to the fact that average exposure concentrations were similar at the three lowest WAFs, i.e. 0.026-0.044 mg/L and at the three highest WAFs (0.31-0.41 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
