Additional information
The acute toxicity of the test item to fish (zebrafish) was determined according to the principles of the OECD-Guideline for Testing of Chemicals No. 203 (1992) and EU Council Regulation (EC) No 440/2008/method C.1 (2008). An acute toxicity test with the saturated solution (nominal loading of 1.00 mg/L) was conducted under semi-static conditions with one water renewal after 48 hours of exposure. Duration of the test was 96 hours.
The saturated solution of the test item didn´t show any signs of toxicity nor lethality at all observation time points. Therefore, the NOEC and LC0were laid down as 1.00 mg/L (based on the nominal concentration) and LC100was laid down as > 1.00 mg/L (based on the nominal concentration).
In the acute immobilisation test with aquatic invertebrates (Daphnia magna) the effects of the saturated solution with a nominal loading of 1.00 mg/L of the test item were determined according to OECD-Guideline for Testing of Chemicals No. 202 (2004). The limit test was conducted under static conditions over a period of 48 hours.
The saturated solution of the test item didn´t show any signs of toxicity nor lethality at all observation time points up to 48 hours. Therefore, the NOEL was laid down as 1.00 mg/L (based on the nominal concentration) and EL100was laid down as > 1.00 mg/L (based on the nominal concentration).
The toxicity of the test item to the unicellular freshwater green alga (Desmodesmus subspicatus) was determined according to the principles of OECD 201 (2011) and Council Regulation (EC) No 761/2009/Method C.3. The study was conducted under static conditions with a saturated solution prepared from a nominal concentration of 1.00 mg/L of the test item. In this study the test item did not cause any inhibiting effects to Desmodesmus subspicatus after 72 hours.
The No Observed Effect Concentration (NOEC) was assessed as 1.00 mg/L and the EC50 was laid down as > 1.00 mg/L (based on the nominal concentration)
A respiration inhibition test with activated sludge according to OECD 209 (2010) was performed under static conditions with the nominal limit concentration of 1000 mg/L. The test system was activated sludge of a municipal sewage treatment plant. The test item caused no inhibiting effects at a concentration of 1000 mg/L to activated sludge. NOEC ≥ 1000 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).
