Description of key information

The n-pentane Koc of 794.3 was calculated in accordance with the TGD using the log Kow of 3.45 which resulted in a Log Koc of 2.9. This data was read across to the Hydrocarbon, C5, n-alkanes,isoalkanes. 

Key value for chemical safety assessment

Additional information

The calculated Koc of 794.3 was used in the EU RAR for n-pentane and so is considered suitable as key study for this endpoint. This value indicates that although the adsorptivity of n-pentane is moderate it still has good mobility in the environment.
