Applicant's summary and conclusion

Conclusions:
The most abundant component of the registered UVCB is predicted to partition mainly to soil (approximately 79 %).
Executive summary:

Since the registered UVCB substance is not readily biodegradable, distribution of the most abundant constituent was predicted using a Level III Fugacity Model. The constituent is predicted to partition mainly to soil (approximately 79 %).
