Additional information
In a GLP study according to OECD 202, the acute toxicity of the reaction product of 2,3-dinitrotoluene and 2,6-Dinitrotoluene and hydrogen to the waterflea (Daphnia magna) was studied. The test concentrations were analytically verified and remained within 20% of the nominal values. Based on nominal concentrations, the 48 -h EC50 is 34.1 mg/L. The 48 -h NOEC was determined to be 10 mg/L (BASF SE, 2011; Project No. 50E0117/10E112).
This result is supported by a screening test with Daphnia magna performed in the same laboratory under similar conditions, but without GLP conditions and analytical verification of the test substance concentrations. Based on nominal values, the EC50 was determined to be between 10 and 100 mg/L (BASF SE, 2010; Project No. 60E0117/10E119).
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.
