Description of key information
The test substance VC did not induce acute immobilisation of Daphnia magna at or below 1.9 mg/L after 48 hours of exposure (NOEC). The 48h-EC50 was 4.9 mg/L (95% confidence interval between 4.3 and 5.9 mg/L).
Key value for chemical safety assessment

- 4.9 mg/L
Additional information
In a 48 h acute toxicity study conducted according to OECD guideline 202 and GLP, water fleas (Daphia magna) were exposed to the test substance under flow-through conditions at the following nominal concentrations: 0 (blank-control),1.0, 1.8, 3.2, 5.6 and 10 mg/L. The 48h-EC50 was 4.9 mg/L based on average concentrations of the stock solutions (95% confidence level between 4.3 and 5.9 mg/L). The study is considered to be reliable without restrictions.
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.
