Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 220 mg/L
Additional information
A GLP guideline study according to OECD 209 is available for the reaction mass of N1,N3-bis(3-aminopropyl)-2-methyl-cyclohexane-1,3-diamine and N1,N3-bis(3-aminopropyl)-4-methyl-cyclohexane-1,3-diamine (DAP-MCDA).
The respiration inhibition test used activated sludge as inoculum taken from a wwtp treating predominantly domestic sewage. The 3-h EC10 was determined to be 220 mg/L, the 3 -h EC20 was 520 mg/L and the 3-h EC50 was >1000 mg/L (BASF SE, 2018; report no. 08G0592/17G605).
It can be concluded that the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
