Description of key information

Triethanolamine is rapidly biodegraded and mineralized in soil under semi-realistic conditions.

Key value for chemical safety assessment

Half-life in soil:
1.8 d

Additional information

As key study regarding the biodegradation of 2,2',2''-nitrilotriethanol in soil performed by West et al. (1996) is identified. Depending on the initial test substance concentration under semi-realistic conditions with soil microcosms using natural sandy loam soil a maximum biodegradation half-life of 1.8 days and a maximum mineralization half-life of 5.4 days were determined.
