Description of key information

The inhibition of the degradation activity of activated sludge is  not anticipated (EC10 > 1000 mg/L).

Key value for chemical safety assessment

Additional information

The toxicity of Amides, C16-C18 (even), N,N'-ethylenebis to activated sludge was investigated in one study according to OECD 209 (Clariant, 1989). The results from this test show no effects on the respiration rate of activated sludge up to the highest nominal test concentration of 1000 mg/L. Therefore, disturbances in the biodegradation process of activated sludge is not anticipated (NOEC >= 1000 mg/L).
