Applicant's summary and conclusion
- Conclusions:
- In conclusion, the log of the adsorption coefficient (Koc) of ucb 22060 was estimated to be log KOC = -0.3 which is equal to a Kocvalue of 0.5 using the HPLC method. This value indicates that ucb 22060 will not be absorbed by organic carbon in soil and that ucb 22060 is very high mobile.
