Petroleum hydrocarbons sorption

The presence of a residual hydrocarbon phase in soils or sediments has been shown to increase the soil- or sediment-water distribution coefficients of poorly water-soluble organic contaminants [463,464]. Such petroleum-hydrocarbon-based phases have been shown to function as effective partition media for PCB congeners [467]. In general, sorption of contaminants by soils and sediments reduces their bio availability to microorganisms [468,469]. In this fashion, the... [Pg.403]

Partitioning of petroleum hydrocarbons (i.e. sorption-bonding) by the active soil fractions mineral surfaces occurs only when the water solubility of the PHCs is exceeded and the hydrocarbons are acconunodated in the micellar form. The accommodation concentration of hydrocarbons in the pore-water has been found to be useful in reflecting the partitioning... [Pg.14]
