Additional information

To determine the toxic effects of the multi-constituent substance to algae, a GLP study performed for the component 1,8-Diazabicyclo(5.4.0)-undec-7-ene (CAS 6674-22-2) is available. The procedures of this test followed the EEC guideline 79/831/EEC, Annex V, Part C. Based on growth rate an EC50 (72 h) > 100 mg/L (nominal) for Desmodesmus subspicatus was determined [BASF 1994].
