Description of key information
The test substance did not exert any effect on the Daphnia at either concentration after 48 h and therefore, the NOEC was > 20 mg/L.

Additional information
Acute Toxicity to Daphnia
Study 1:
The purpose of this study was to determine the acute toxicity of the test substance Becrosan 6920 to Daphnia magna by measuring the percentage of daphnia immobilized following 48 h of exposure to the test material.
In this test, the daphnids were exposed to two concentrations of the test substance, 2 and 20 mg/L, in water without using any solubilizing agent. The test substance did not exert any effect on the Daphnia at either concentration after 48 h and therefore, the NOEC was > 20 mg/L.
Study 2:
The acute toxicity of Becrosan 6920 to Daphnia magna was tested according to the guideline 92/69/EEC, part C.2. The Daphnia were exposed to nominal concentrations of the substance in a range of 30 mg/l to 227 mg/l for 48 hours. The concentration of the substance in test water was measured by determination of the Dissolved Organic Carbon (DOC).
In this test, the toxicity values were based on nominal concentrations. The 24 h EC0 and EC100 is 67 mg/l and greater than 227 mg/l, respectively. The 48 h EC0 and EC100 is 43 mg/l and greater than 227 mg/l, respectively.
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.
