Key value for chemical safety assessment

Additional information

A GLP-study on growth inhibition of the freshwater algae D. subcapitata, exposed to the test substance (DBU, CAS 6674 -22 -2) was performed according to EEC guideline 79/831/EEC, Annex V, Part C. Based on growth rate, the 72h-EC50 as well as EC10 were found to be >100mg/L. Regarding biomass, a NOEC of more than 100 mg/L is reported, additionally. (BASF AG, Rep. no.: 92/2438/60/1, 1994). The results were analytically verified .

Concerning these results, DBU (CAS 6674 -22 -2) can be regarded with high probability to be acutely not harmful to algae.
