Humic substances or, more generally, dissolved organic material (DOM), in the natural waters are important in water chemistry and aquatic toxicology because number of studies have demonstrated that they can bind hydrophobic organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polychlorinated dioxins and dibenzofurans (1-3). However the affinity of the organic matter for binding a given pollutant varies among waters from different sources. The purpose of this study was to demonstrate that isolated subcomponents of DOM (XAD-8 fractionations) differ in their affinity for binding contaminants, and to determine whether the relative binding affinities and relative abundance of the subcomponents could account for the correlations observed in the different sources of DOM.
