Key study regarding OECD Guideline 106:
The adsorption and desorption isotherm showed a strong positive monotonic relationship between log Ce and log X/m, indicated by the correlation coefficients being close to 1. These values characterise the test substance as slightly mobile (Koc 500-4000) to non-mobile (Koc>4000) in the four soils and one sediment used in this study. Mass balance for the four soils and one sediment were in the range 86 to 96%.
Henry's Law constant
The air/water partition coefficient at ambient temperature of the substance C8-2 FTOH (fluorinated telomer alcohol, CAS No. 678 -39 -7) was calculated with the use of the LSER approach. The coefficients for the underlying Abraham equation were determined experimentally. In addition, QSAR calculations with 4 different models were performed. The results for 4 fluorinated telomer alcohols
are presented in the table:

Comparison of the experimental and calculated data for C4-2 and C6-2 FTOH reveals that the LSER calculations result in the most reliable estimation. They are based on a large number of different experimental partition data for the Fluoro-telomers.
