Reference
Endpoint:
adsorption / desorption: screening
Type of information:
(Q)SAR
Adequacy of study:
other information
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification
Principles of method if other than guideline:
The adsorption/desorption coefficient (Koc) of ETFBO was estimated with the model PCKOCWIN v1.66 (2000) from EPI (Estimation Program Interface) suite, developped by EPA's Office of Pollution Toxics and Syracuse Research Corporation.
GLP compliance:
no
Type of method:
other: QSAR prediction using PCKOCWIN v1.66 (2000) from EPI suite.
Specific details on test material used for the study:
The QSAR model was run using the generic CAS number 17129-06-5 corresponding to the unspecified cis-trans isomery.
Type:
Koc
Remarks:
QSAR prediction
Value:
10
Type:
log Koc
Remarks:
QSAR prediction

1
Validity criteria fulfilled:
not applicable
Conclusions:
The QSAR-predicted Koc value was 10 (Log Koc = 1).
Executive summary:

The adsorption/desorption potential of ETFBO was studied by predicting the adsorption/desorption coefficient (Koc) with the model PCKOCWIN v1.66 (2000) from EPI (Estimation Program Interface) suite, developped by EPA's Office of Pollution Toxics and Syracuse Research Corporation. A Koc value of 10 was predicted (Log Koc = 1); suggesting mobility in soils.

Description of key information

The QSAR-predicted Koc value was 10 (Log Koc = 1); suggesting mobility in soils.

Key value for chemical safety assessment

Additional information

A QSAR prediction was reported in an internal memorandum with limited documentation/justification. In spite of this limitation, it brings some indication of the adsorption/desorption potential and was reported in the registration dossier for information.
