Endpoint:
adsorption / desorption: screening
Type of information:
(Q)SAR
Adequacy of study:
key study
Study period:
Not applicable
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
The value for Koc is derived using EUSES v 2.1. The programme incorporates the standard EU Risk Assessment guidance including determination of Koc based on chemical classes. The default class is "non-hydrophobics"
