Description of key information
Additional information
Short-term toxicity to fish
The acute toxicity of the test material to the freshwater fish rainbow trout (Oncorhynchus mykiss) has been investigated and gave a 96-hour LC50 value of 20 mg/L with 95 % confidence limits of 17 - 25 mg/L. The No Observed Effect Concentration (NOEC) was 10 mg/L.
Short-term toxicity to aquatic invertebrates
The acute toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 value of 9.5 mg/L with 95 % confidence limits of 7.8 -11 mg/L. The No Observed Effect Concentration at 48 hours was 3.2 mg/L.
Long-term toxicity to aquatic invertebrates
The long-term and reproduction toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and following results were achieved: The 14 and 21-day EC50 (immobilisation) values, based on nominal test concentrations, for the parental Daphnia generation (P1) were calculated to be 2.8 and 2.5 mg/L with 95 % confidence limits of 1.5 - 5.7 mg/L and 0.97 - 4.3 mg/L, respectively. The No Observed Effect Concentration was 3.2 mg/L.
Toxicity to aquatic algae
The effect of the test material on the growth of Scenedesmus subspicatus has been investigated over a 72-hour period and gave an ErC50 (0 - 72 h) value of 12 mg/L; 95 % confidence limits 9.7 - 15 mg/L. The No Observed Effect Concentration at 72 hours was 1.0 mg/L.
Toxicity to microorganisms
Under the conditions of the performed Activated Sludge Respiration Inhibition Test, the EC50 value for the test item following 3 h incubation was determined as 1400 mg/L. The No Observed Effect Concentration (NOEC) after 3 hours was determined as 180 mg/L.
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.
