Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Based on ThOD results obtained for the substance N,N-dimethylaniline, it can be observed that 75% degradation within 28 days at the concentration of 95.5 mg/l. Thus it can be concluded that substance N,N-dimethylaniline is found to readily biodegradeble.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
No. of studies of target substance N,N-dimethylaniline reviewed for Biodegradation in water: screening tests from reliable sources having Klimisch rating 2 & 4.

Considering the weight of evidence approach and studies reviewed for target chemical N,N-dimethylaniline and read-across chemical N,N-diethylanilineit is concluded that the N,N-dimethylaniline is readily biodegradable in nature.Thus this also confirmed thatthe N,N-dimethylaniline is not persistent in nature.
