Description of key information

With high probability the mixture is acutely not harmful to aquatic algae.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
75.6 mg/L

Additional information

In a GLP study according to OECD 201, the growth inhibition of the reaction product of 2,3-dinitrotoluene and 2,6-Dinitrotoluene and hydrogen to unicellular green algae (Desmodesmus subspicatus) was tested. The test concentrations were analytically verified. They remained within 20% of the nominal values, therefore the effect values are given based on nominal concentrations. Based on growth rate inhibition, the 72 -h ErC50 is greater than 220 mg/L. The 72 -h ErC10 was determined to be 75.6 mg/L (BASF SE, 2011; Project No. 60E0117/10E119).
