1 Sampling points were excluded from the calculations since there was a power failure in the night from 06 Jul 2022 to 07 Jul 2022.
2 Additional sampling took place since the initial calculation of the mean log Dow value with four time points yield a slope that is not significantly different
from zero at a p-level of 0.05

1 Due to the system problems samples were analyzed on 07 Sep 2022. They were stored in the autosampler until analysis. Due to that additional samples
were taken on 08 Sep 2022.
2 Estimated values calculated by extrapolation of the calibration curve.
3 Result after re-dilution. Initially the sample was wrongly diluted.

Applicant's summary and conclusion
- Conclusions:
- The slow-stirring method at pH 7 and pH 11 was applied for the determination of the partition coefficient/distribution coefficient (Pow / Dow) of JNJ-73848281-AAA (T003904).
The Pow /Dow and log Pow /log Dow values of the test material at pH 7 and pH 11 were:
pH 7: Dow 2.0E3, log Dow 3.3
pH 11: Pow 2.4E4, log Pow 4.4
