Conclusions:
The half-life period of test chemical in soil is estimated to be  30 days (720 hrs). Based on this half-life value of test chemical, it is concluded that the chemical is not persistent in the soil environment and the exposure risk to soil dwelling animals is moderate to low.
Executive summary:

The half-life period of test chemical in soil was estimated using Level III Fugacity Model by EPI Suite version 4.1 estimation database (EPI suite, 2018). If released into the The half-life period of test chemical in soil is estimated to be  30 days (720 hrs). Based on this half-life value of test chemical, it is concluded that the chemical is not persistent in the soil environment and the exposure risk to soil dwelling animals is moderate to low.environment, 74 % of the chemical will partition into soil according to the Mackay fugacity model level III.
