Applicant's summary and conclusion

Conclusions:
The average of measured log Koc values was 1.86 and the difference between two measured values was 0.00. It is judged that the test results are valid because the difference between two measured values was less than 0.25.
Executive summary:

The average of measured log Koc values was 1.86 and the difference between two measured values was 0.00. It is judged that the test results are valid because the difference between two measured values was less than 0.25.
