Description of key information
For acute toxicity (EC50, LC50) in D. magna, the VEGA/COMBASE and VEGA/IRFMN models provide predictions for the target compound of 107.95 mg/l (EC50) and 5.97 mg/l (EC50), respectively, associated with a low reliability mainly due to the lack of similar compounds. Similarly, the VEGA/DEMETRA and VEGA/EPA models provide predictions of 9.25 mg/l (LC50) and 40.86 mg/l (LC50), respectively, associated with a low reliability.
With regard to chronic toxicity in D. magna, the VEGA/IRFMN predicts 1.43 mg/l of NOEC for the compound of concern, reporting low reliability and ADI= 0.237. In all the cases, the ADI is < 0.45.
Overall assessment. The predictions for acute toxicity resulting from VEGA/COMBASE and VEGA/IRFMN models (EC50) are contradictory and not associated to the necessary reliability to provide a definite assessment. However, results from VEGA/DEMETRA and VEGA/EPA models can
provide a more defined assessment, possibly assuming a LC50 between 9.25 - 40 mg/l. Similarly, the predicted value for NOEC = 1.43 seems to be in line with acute contact toxicity effects, thus it should be taken into account for chronic toxicity effects.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
