In sample S2, KMn[O.sub.4] oxidation (MN-2) (with a smaller decrease of OC, 1.3 mg [g.sup.-1]) caused a strong decline in carbohydrate products (from 31.5% of TQPA in NO-2 to 17.4% in MN-2) and an increase in aliphatic pyrolysis products (sum of n-alkanes, n-alkenes and other aliphatic compounds from 5.3% in NO-2 to 23.1% in MN-2).

Use of this hydrophobicity index may improve prediction of water repellency from soil properties, as it is a direct measure of the proportion of C in the soil present as aliphatic compounds which cause water repellency.

Infrared microscopy can be used to identify hydrophobic aliphatic compounds in the coating on a single sand grain.

Soils under permanent grassland had higher aggregates stability caused by higher content of aliphatic compounds. Disturbance of humic acids aggregate ability due to not appropriate soil tillage system in agriculture is a common phenomenon.

It is not possible (according to the available knowledge) to eliminate the formation of PAH in the obtained oil without elimination or decreasing the aromatization processes via secondary reactions through either a Diels-Alder type reaction or selective cracking of aliphatic compounds resulting in selective concentration of aromatic compounds.

* The formation of aromatics via secondary reactions during pyrolysis has been attributed to Diels-Alder type reactions or to gas-phase cracking of aliphatic compounds resulting in selective concentration of aromatic compounds.
