Description of key information
A range of adsorption/desorption coefficient log values was calculated: 76.2% of the components have Log Koc ranged from 1.80 to 2.06.
Key value for chemical safety assessment
- Koc at 20 °C:
- 115
Additional information
The adsorption/desorption coefficients of this complex reaction product were calculated according to Gerstl (1990), Briggs (1981) and Nendza (1998) based on the experimental values of n-octanol/water partition coefficient.
A range of adsorption/desorption coefficient values was obtained: 1.53 to 2.37, 76.2% of the components have Log Koc ranged from 1.80 to 2.06.
The components with log Koc values between 1.80 and 2.06 being the most abundant (76.2%), the highest log Koc value (2.06) in this range was used for chemical safety assessment (CSA) and for the derivation of Predicted No-Effect Concentrations (PNEC) in sediments and soil. This value was considered as a worst-case value, increase of adsorption/desorption coefficient value leading to a significant increase of the PEC soil value.
[LogKoc: 2.06]
