TL;DR: In this article, the authors measured phenanthrene sorption and desorption equilibria for 10 natural sorbents having significantly different geological ages and organic matter compositions, including three geologically young peats, one humic acid, three geologists old shales, and samples of kerogen isolated from each of the shales.

TL;DR: A recent review as mentioned in this paper highlights the major progress over the last decade on characterization of geochemically heterogeneous soil/sediment organic matter (SOM) and the impacts of SOM heterogeneity on sorption and desorption of hydrophobic organic contaminants (HOCs) under equilibrium and rate limiting conditions.

TL;DR: In this article, the authors examined the time dependence of solute phase distribution relationships (PDRs) in completely-mixed batch reactors and found that nonequilibrium PDRs changed from approximately linear form to increasingly nonlinear form as the time of reaction increased.

TL;DR: In this paper, the results reveal that the Freundlich model and the DRDM fit the data well, whereas a linear model fails to do so; values of the organic carbon-normalized distribution coefficient, KOC, calculated from individual isotherm points for a specific sorbent−solute system vary significantly with the aqueous-phase solute concentration, Ce; and all commonly used correlations of KOC with octanol−water partitioning coefficients and solute solubility limits significantly underestimate KOC for Ce values smaller than approximately one-tenth of a

TL;DR: In this paper, the authors measured the apparent isotherm hysteresis of an organic contaminant probe, phenanthrene, and five EPA reference soils and sediments to evaluate the existence and extent of apparent hystresis, and three different experimental protocols were tested to assess their relative potentials for introduction of artifact.
