Description of key information
14-d EC50: >159 ng/l; 14-d NOEC 159 ng/l (highest concentrations tested) (mean measured concentrations): effects of the test substance on sublethal effects and mortality of Oncorhynchus mykiss.
96-h LC50: >182 ng/l; 96-h NOEC 182 ng/l (highest concentrations tested) (mean measured concentrations): effects of the test substance on mortality of Oncorhynchus mykiss.
Key value for chemical safety assessment
Additional information
Two toxicity studies are available with fish:
A 14 day EC50 value of >159 ng/l and a NOEC value of 159 ng/l (highest concentrations tested), based on mean measured concentrations, have been determined for the effects of the test substance on sublethal effects and mortality of Oncorhynchus mykiss, in accordance with OECD Guideline 204.
The test solution preparation method and test system design indicate that the test organisms were predominantly exposed to the parent substance.
A 96 hour LC50 value of >182 ng/l and a NOEC value of 182 ng/l (highest concentrations tested), based on mean measured concentrations, have been determined for the effects of the test substance on mortality of Oncorhynchus mykiss, in accordance with OECD Guideline 203. All fish in the control and treatment groups appeared normal throughout the test and showed no overt signs of toxicity.
The test solution preparation method and test system design indicate that the test organisms were predominantly exposed to the parent substance.
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).
