Results and discussion

Adsorption coefficientopen allclose all
Type:
log Koc
Value:
8.92
Remarks on result:
other: MCI method
Type:
log Koc
Value:
3.333
Remarks on result:
other: Kow method

Any other information on results incl. tables

MCI method: "very high" adsorption potential (Blume scale)

Kow method: "high" adsorption potential (Blume scale)

The value obtained with the Kow method is preferred because it is not exclusively based on structural elements but also considers experimental data of this specific substance.

Applicant's summary and conclusion

Validity criteria fulfilled:
not applicable
Conclusions:
With a calculated log Koc of 3.333 , the sorption potential of the substance to soil or sediment organic matter is expected to be high (Blume scale).
Executive summary:

With a calculated log Koc of 3.333 , the sorption potential of the substance to soil or sediment organic matter is expected to be high (Blume scale).
