Any other information on results incl. tables
The soil and sediment partition coefficient (log Koc) of PTPA was calculated from the categorical log Kow range of 5.3 to 6.1 using the equation from European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4, 'Predominantly hydrophobics". The calculated range of log Koc (soil and sediment partition coefficient) is calculated to be 4.4 to 5.0 (log units).
Applicant's summary and conclusion
- Conclusions:
- The calculated range of log Koc (soil and sediment partition coefficient) is 4.4 to 5.0 (log units) based on the categorical log Kow range of 5.3 to 6.1.
- Executive summary:
The soil and sediment partition coefficient (log Koc) of PTPA was calculated from the categorical log Kow range of 5.3 to 6.1 using the equation from European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4. The calculated range of log Koc (soil and sediment partition coefficient) is 4.4 to 5.0 (log units).
It is considered reliable (with restrictions) and is suitable for Risk Assessment, Classification & Labelling, and PBT Analysis.
