Abstract

The retention factors (k) of 104 hydrophobic organic chemicals (HOCs) were measured in soil column chromatography (SCC) over columns filled with three naturally occurring reference soils and eluted with Milli-Q water. A novel method for the estimation of soil organic partition coefficient (K_oc) was developed based on correlations with k in soil/water systems. Strong log K_oc versus log k correlations (r>0.96) were found. The estimated K_oc values were in accordance with the literature values with a maximum deviation of less than 0.4 log units. All estimated K_oc values from three soils were consistent with each other. The SCC approach is promising for fast screening of a large number of chemicals in their environmental applications.
