Conclusions:
Biodegradation half-life of test substance 4-Piperidinol, 1-methyl- in soil was estimated to be 30 days (720 hrs).
Executive summary:

Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of 4-Piperidinol, 1-methyl- (CAS No. 106 -52 -5) in soil was obtained to be 30 days (720 hrs). Based on this half-life value of 4-Piperidinol, 1-methyl-, it isconcluded that the chemical is not persistent in the soil environment.
