| Summary: | The sorption of pyrene, 3-methylcholanthrene, 7,12-dimethylbenz(A)anthracene, and dibenzanthracene on 14 soil and sediment samples exhibiting a wide range of physicochemical properties was studied. The equilibrium Freundlich constants and linear partition coefficients for each compound were highly correlated with the organic carbon content of the soils/sediments tested. No other significant correlations with soil/sediment properties were observed. The sorption constants when normalized to organic carbon content of the substrate predicted the octanol-water partition coefficients for the compounds tested. A highly significant negative correlation was observed between log substrate and log water solubility for these compounds. Experimental values of the water solubility and octanol-water partition coefficients for the four compounds are reported. |
