Description of key information
Short-term toxicity to Fish
In a 96-hour static acute toxicity test to Zebrafish (Danio rerio) with the test item according to EU Method C.1 (Acute toxicity to fish), the 96-h LC50 value was determined to be 9.027 mg/L.
Short-term toxicity to Daphnia
In a 48-hour static acute toxicity test to Daphnia magna with the test item according to EU Method C.2 (Acute Toxicity for Daphnia), the EC50 value was determined to be 3.56 mg/L. The NOEC was determined to be 1.102 mg/L.
Algal Growth Inhibition
In a 72-h algal growth inhibition test on Pseudokirchneriella subcapitata with the test item according to EU Method C.3 (Algal Inhibition test), the 72-h EC50 based on growth rate was determined to be 2.11 mg/L and the EC10 based on growth rate was determined to be 1.55 mg/L. The NOEC was determined to be 0.36 mg/L.
Activated Sludge
In comparison to the inoculum controls the respiration rate of the activated sludge was inhibited between 4.4 % and 96.5 % in the examined nominal test concentration range. The inhibition showed a dose-related tendency. The respiration rate was inhibited with 96.5 % at the highest concentration level of 1000 mg/L. Concentrations exceeding 1000 mg/L nominal were not tested. The NOEC was determined to be 31 mg/L and the EC50 was determined to be 119.5 mg/L.
Additional information
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.
