- Conclusions:
- Biodegradation half-life of test substance Diphenylacetonitrile in soil was estimated to be 75 days (1800 hrs).
- Executive summary:
Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of Diphenylacetonitrile (CAS No. 86 -29 -3) in soil was obtained to be 75 days (1800 hrs). Based on this half-life value of Diphenylacetonitrile, it is concluded that the chemical is not persistent in the soil environment.
