Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The adsorption coefficient of the test substance was determined to be 1.6 x 105 (log Koc 5.21) at 35 degrees celsius. For four impurities, the adsorption coefficient was determined to be 6.6 x 103 (log Koc 3.82), 1.3 x 104 (log Koc 4.12), 3.7 x 104 (log Koc 4.57) and 9.1 x 104 (log Koc 4.96) at 35 degrees celsius.
Executive summary:

The adsorption coefficient of the test substance was determined to be 1.6 x 105 (log Koc 5.21) at 35 degrees celsius. For four impurities, the adsorption coefficient was determined to be 6.6 x 103 (log Koc 3.82), 1.3 x 104 (log Koc 4.12), 3.7 x 104 (log Koc 4.57) and 9.1 x 104 (log Koc 4.96) at 35 degrees celsius.
