Effect of water saturation in soil organic matter on the partition of organic compounds
Article Abstract:
The impact that water saturation has on the solute partition in soil organic matter (SOM) was studied. Sorption data on benzene, carbon tetrachloride and trichloroethylene were obtained. Florida peat and Michigan muck, soils with a high organic content, were used. The research indicates that the partition in the SOM is the primary process in the uptake of the three volatile organic liquids. The suppression of adsorption by minerals is more dominant than the mitigation of the partition effect in SOM.

Partition of nonpolar organic pollutants from water to soil and sediment organic matters
Article Abstract:
Measurement of the partition of coefficient of carbon tetrachloride and 1,2-dichlorobenzene of soils and sediment beds from the US and China revealed high similarity between normal soils and normal bed sediments. This is attributed to the similarity of organic matters, soil composition and soil polarities, despite different geographical locations. Change in the type and mount of organic matter in soil can also be attributed to soil erosion, which converts eroded soils into sediment beds.

Partition characteristics of polycyclic aromatic hydrocarbons on soils and sediments
Article Abstract:
A particular behavior exhibited by polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, phenanthrene and pyrene from water on soils and sediments, is the enhanced partition of PAHs in soil/sediment organic matter (SOM). The improved partition of PAHs in SOM is caused by the enhanced compatibility of their cohesive energy densities with those of the aromatic components present in SOM.
