ABSTRACT
In a recent review article, Luthy et al. (1) address the lack of fundamental understanding of the behavior of geosorbents (soils and sediments) and the chemical interactions of hydrophobic organic chemicals (HOCs). The claim is made that, while macroscopic assessments of sorption/desorption isotherms and mass-transfer rates are useful, a greater fundamental understanding of geosorbents at the microscale is needed to advance the science of HOC fate, transport, and risk assessment. Luthy et al. (1) cited the rich literature on the characteristics of HOC partitioning by geosorbents.
