Materials and methods
- Principles of method if other than guideline:
- Calculated usind PCKOC Program v1.66 of EPI-Suite software as well as according to Sabljic (1995) and Gerstl (1990).
The calculation of PCKOC program is based upon the molecule structure using the molecular connectivity method.
The calculation according to Sabljic (1995, QASR Modelling of Soil Sorption. Improvements and Systematics of logKoc vs. logKow Correlations. Chemosphere, Vol. 31, pp. 4498-4514) is based on a statistical relationships between Koc and the octanol/water partition coefficient.
The calculation according to Gerstl (1990, Estimation of Organic Chemical Sorption by Soils, Journal of Contaminant Hydrology, 6, pp. 357-375) is based on a statistical relationships between Koc and the octanol/water partition coefficient. - GLP compliance:
