Description of key information
The test substance is acutely very toxic to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
The acute toxicity of the test substance to the water flea Daphnia magna was determined according to the OECD guideline 202 (RCC Ltd., 2003). The test was performed under static conditions. Since the test item contains two different isomers, five WAFs (water accommodated fractions) with loading rates of 0.46, 1.0, 2.2, 4.6, and 10 mg/L have been tested. The test concentrations were analytically verified at the beginning and at the end of the test. The test substance was stable during the test period.
After 48 hours an EC50 value of 0.56 mg/L mean measured (= 0.68 mg/L loading rate) was determined . The NOEC/EC0 was determined to be 0.42 mg/L mean measured (= 0.46 mg/L loading rate) after 48 h.
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.
