Description of key information

Adsorption / desorption:

This endpoint is characterised for Heptadecane using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK report attached in IUCLID section 13).

Adsorption coefficient has been calculated using Petrorisk. The Koc for Heptadecane ranges from 2.51 x10^5 - 1.38 x10^7.

The following data on other representative substances have been included as a weight of evidence. The data is estimated using the calculation in the Concawe Library of Petrorisk, using SPARC v4.2 program (May 2008).

Koc of the read-across substance icosane has been estimated by calculation in the Concawe Library of Petrorisk, using SPARC v4.2 program (May 2008). The calculated value is 1.84 x 1011L/kg, using a log Kow of 11.46. This result suggests that icosane is expected to be immobile in soil.
