Log Kow (estimated) : 0.66

Log Kow (user-entered): 0.12 (used in Kp calculations)

GENERAL Equation: log Kp = -2.80 + 0.66 log Kow - 0.0056 MW

Kp (predicted): 4.36e-004 cm/hr

Applicant's summary and conclusion

Conclusions:
According to the DK-EPA heuristics a Kp values of 0.000436 cm/hr is indicative for a very low bioavailability of the test substance from an aquaeous medium.
Executive summary:

According to the DK-EPA heuristics a Kp values of 0.000436 cm/hr is indicative for a very low bioavailability of the test substance from an aquaeous medium.
