Description of key information
Daphnia magna was exposed under static condition for 48 h to six concentrations (0.08, 0.17, 0.38, 0.83, 1.8 and 4 mg/L) of the test substance. Theeffect concentration was determined as EC50 = 1.90 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 1.9 mg/L
Additional information
In order to test acute toxicity to invertebrates of the substance, Daphnia Magna, was exposed to the test solution of six concentrations of the test substance ( 0.08, 0.17, 0.38, 0.83, 1.8 and 4 mg/L) and blank control solution for a period of 48 h under static conditions.Mobility and visible abnormalities were recorded at 24 and 48 h. The measured concentrations confirmed that deviation from the nominal concentrations was less than 21 % (measured concentrations were in the range of 80.0 % to 100.75 % of nomianl concentrations). An effect concentration showed an EC50 = 1.90 mg/L. The toxcitity study is classified as accetable and satisfies the guideline requirements for the acute Daphnia study.
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.
