Description of key information

Based on the available studies on biodegradation and the relatively low sorption potential, 1 -methylpiperazine is expected to be non-persistent in water, soil or sediment and for more than 99% removed from waste water in a sewage treatment plant.

Key value for chemical safety assessment

Half-life in freshwater:
15 d
at the temperature of:
12 °C
Half-life in freshwater sediment:
30 d
at the temperature of:
12 °C
