Description of key information
Three logKoc values were estimated according to different calculation models. All models indicate a high adsorption potential of cholesterol (log Koc between 4.94 and 6.58).
Key value for chemical safety assessment
- Koc at 20 °C:
- 86 400
Additional information
Three log Koc values were estimated according to different calculation models. All models indicated a high adsorption potential of cholesterol (logKoc between 4.94 and 6.58).
This is supported by literature data indicating that in raw sewage, most (80 -95%) of the sterols (incl. cholesterol) were in the particulate fraction (see section 5.5.1).
Based on the influence of the logKoc on the distribution in the STP, the lowest logKoc will result in the lowest partitioning to sludge. As the sludge of the relevant STP is incinerated, this scenario is deemed worst case as the release to the aquatic environment will be the highest. Therefore, a log Koc of 4.94 was chosen as worst case approach value.
[LogKoc: 4.94]
