Description of key information

Its half-life in soil, 720 hrs (30 days). does not exceeds the EPA criteria of >= 2 months (and <= 6 months). Therefore,piperazine adipate is estimated not to be persistent in the soil environment.

Key value for chemical safety assessment

Half-life in soil:
720 h
at the temperature of:
25 °C

Additional information

The EPI Suite has estimated that piperazine adipate is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 720 hrs (30 days). does not exceeds the EPA criteria of >= 2 months (and <= 6 months). Therefore,piperazine adipate is estimated not to be persistent in the soil environment.
