- Conclusions:
- Please refer to the attached QPRF for justification of suitablility of this approach. The estimation software gives a Koc value estimates as follows:
>= 101800 - <= 6262000 L/kg by Koc (KOCWIN) - MCI
>= 5.0077 - <= 6.7967 dimensionless by Log Koc (KOCWIN) - MCI
>= 897400 - <= 6.479E7 L/kg by Koc (KOCWIN) -Kow
>= 5.953 - <= 7.8115 dimensionless by Log Koc (KOCWIN) -Kow
The substance is predicted to adsorp to soil on this basis.
