Description of key information

Due to character of the substance (complex material containing both inorganic and organic substances) it is not possible to perform Partition coefficient study. 
The calculation of log Kow for the inorganic phase is not possible - no (Q)SAR methods are applicable for inorganic substances. The value of partition coefficient is additionally not required by REACH (Annex VII, 7.8, column 2).
The calculation of log Kow of the main of the organic phase is not possible because no of the organic substance contained in the tested substance is not possible to describe as the main component.
The estimation of log Kow based on identified organic substances was performed. The literature data for identified organic substances were used.
The range of log Kow based on the values for identified organic substances is estimated 2.13-6.58.
