It may therefore be concluded that understanding of the basic mechanisms and, in particular, the dynamics of the partitioning of xenobiotics between all phases — including truly dissolved organic matter, colloidal material, and particulate matter — and their relative importance in determining the exposure of biota to xenobiotics is strictly limited and that refinement of many unresolved details is highly desirable. 

Water samples may contain appreciable amounts of particulate matter, dissolved organic carbon, or colloidal material and all of these may form associations with the analytes and affect their recoverability. For these reasons, discrepancies may arise between the concentrations of analytes determined by liquid extraction and those obtained by sorption on polyurethane or XAD resins (Gomez-Belinchon et al. 1988). Empirical procedures have been developed (Landrum et al. 1984) for fractionating samples to assess the relative contribution of the associations of xenobiotics with the various organic components, while sediment traps for collection of particulate matter have been extensively used in investigations in the Baltic Sea where appreciably turbid water may be present (Nat et al. 1992).
