Applicant's summary and conclusion
- Conclusions:
- The calculated weighted average log KOW (log KOW,Av) value for triplicate experimental set-ups was 6.58 with a standard deviation of 0.09. The experimental values are in agreement with the lower range of predicted KOW values by others. The log KOW values of C14 with different chlorine numbers varied between 5.98 and 6.96, and showed no trend with the chlorine number.
- Executive summary:
The objective of this study was to experimentally determine the KOW of a C14 polychlorinated n-alkane test material with 50% Cl content by weight using OECD Test Guideline 123. The calculated weighted average log KOW (log KOW,Av) value for triplicate experimental set-ups was 6.58 with a standard deviation of 0.09. The experimental values are in agreement with the lower range of predicted KOW values by others. The log KOW values of C14 with different chlorine numbers varied between 5.98 and 6.96, and showed no trend with the chlorine number.
