Description of key information

The acute toxicity of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane  to Alga (Desmodesmus subspicatus former name: Scenedesmus subspicatus) was tested according to EU method C.3 'Alga, Inhibition test' (2009). During 72 hours exposure an ErC50 of 280.9 mg/L and EC10 of 63.4 mg/L was estimated (Currenta, 2009).

Key value for chemical safety assessment

EC50 for freshwater algae:
280.9 mg/L
EC10 or NOEC for freshwater algae:
63.4 mg/L
