Values of the organic-carbon-based partition coefficient (Koc) have often been estimated using one-parameter linear free energy relationships (op-LFERs), which include both correlations between log Koc and Kow, where Kow is octanol−water coefficient, op-LFERs that are based on first-order molecular connectivity indices. For chemicals with tendencies toward strong hydrogen-bonding or other specific interactions organic phase, however, these methods not sufficiently accurate. Polyparameter LFERs (pp-LFERs) address shortcomings by explicitly considering contributions change from multiple kinds water bulk phases. This paper reviews pp-LFER theory presents development a new for chemical partitioning soil/sediment matter (SOM) data set 356 carefully selected experimental values 75 chemicals, including apolar, monopolar, bipolar compounds. The paradigm representing SOM single qualitatively supported our results, coefficients regression Koc= (1.10 ± 0.10)E − (0.72 0.14)S + (0.15 0.15)A (1.98 0.14)B (2.28 0.14)V (0.14 0.10) represents proposed water−SOM-specific properties estimating Koc. developed correlation outperformed currently recommended approaches given also compared favorably against use class-specific op-LFER regressions. Overall, approach over current purpose estimation especially polar chemicals.

Sorption coefficients (K(oc) values) of selected endocrine disruptors for a wide variety dissolved organic matter (DOM) were measured using fluorescence quenching and solubility enhancement. 17beta-Estradiol, estriol, 17alpha-ethynylestradiol, p-nonylphenol, p-tert-octylphenol, dibutylphthalate as disruptors. Aldrich humic acid, Suwannee River fulvic acids, Nordic alginic dextran, tannic acid DOM surrogates. The resulting sorption (log K(oc)) independent octanol-water partitioning K(ow)) the disruptors, indicating hydrophobic interaction is not predominant mechanism. Moreover, K(oc) values especially steroid estrogens, correlated much better with UV absorptivity at 272 nm (A272) phenolic group concentration than either H/O or (O+N)/C atomic ratio DOM. This suggests that mechanism closely related to between pi-electrons hydrogen bonds, i.e., affinity groups estrogens suggested provide relatively large contribution overall yield high those alkylphenols dibutylphthalate, which are be dominated by nonspecific interaction.
