Additional information
Key study: Experimental results: Test method was according to OECD 202. The 48h-EC50 for Potassium acetate was greater than 459.5 mg/L with Daphnia magna (basis for effect: mobility). The EC0 (48h) was 282mg/L for Potassium acetate.
Supporting information: Experimental results:
In the first report, test method was equivalent to OECD 202. The acute toxicity test on Daphnia similis under the experimental conditions showed an EC 50 of 1.05 -1.21 g/L after 48 hours (basis for effect: mortality).
In the second report, test method was according to ISO 14669 guideline. It was performed on Acartia tonsa and the EC 50 (48 h) was 2483 mg/L and NOEC was 1250 mg/L (basis for effect: mortality).
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.
