Additional information
For fish (Danio rerio) a LC50 of > 100 mg/l after 96 h was obtained for the test item. The study was conducted in accordance with Council Regulation (EC) No 440/2008, Method C.1 'Acute toxicity for Fish' (2008). The result relates to nominal concentration as analytical monitoring shows stability of the test substance during the experiment. (CURRENTA, 2009).
The acute toxicity of the test substance to Daphnia magna was investigated in a static test according to EC No 440/2008, Method C.2 'Acute toxicity for Daphnia' (2008) which is equivalent to OECD Guideline for Testing of Chemicals No. 202 "Daphnia sp., Acute Immobilisation Test" (adopted April 13, 2004). After 48 hours of exposure an EC50 of > 100 mg/L was determined. The result relates to nominal concentration as analytical monitoring shows stability of the test substance during the experiment (Currenta, 2009).
In 72 h the effective concentration of the test item which reduces the growth rate of Scenedesmus subspicatus CHODAT by 50 % is > 100 mg/l. The experiment was conducted in accordance with OECD Guideline for Testing of Chemicals No. 201 'Alga, Growth Inhibition Test' (2006) and result relates to nominal concentration as analytical monitoring shows stability of the test substance during the experiment (Currenta, 2009).
Assessing the toxicity towords microorganisms, the substance showed 7.2 % respiration inhibition of activated sludge at the highest test item concentration of 1000 mg/l according to the OECD guideline 209 (Currenta, 2009). An EC10 and an EC50 of >1000 mg/l were obtained in this test.
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.
