      abstract     = {Organic matter is considered to be the single most
                      important factor limiting availability and mobility of
                      persistent organic pollutants (POPS) in soil. This study
                      aimed to characterize the distribution of C-14- PCB
                      (congeners 28 and 52) and C-14-PAH (fluoranthene and
                      benzo[a]pyrene) residues in an Orthic Luvisol soil obtained
                      from two lysimeter studies initiated in 1990 at the
                      Agrosphere Institute (Forschungszentrum Julich GmbH,
                      Germany). The lysimeter soils contained a low-density OM
                      fraction, isolated during soil washing, which contained a
                      significant fraction $(3-12\%)$ of the total C-14-activity.
                      Soils were also fractionated according to three particle
                      sizes: > 20, 20-2, and < 2,am. Relative affinity values of
                      14C-activity for the different article sizes varied in the
                      order 20-2 mu m > (< 2 mu m) approximate to (> 20 mu m) for
                      the PCBs. Relative affinity values of C-14 -activity for the
                      different particle sizes varied in the order 20-2 mu m > (<
                      2 mu m) > (> 20 mu m) for the PAHs. The distribution of
                      C-14-PCB or C-14- PAH residues in the organic and inorganic
                      matrixes of the particle-size fractions was determined using
                      methyl isobutyl ketone (MIBK). C-14- PCB and
                      C-14-PAH-associated activities were primarily located in the
                      humin fraction of the 20-2 and < 2 mu m particlesize
                      fractions of the soil. A small fraction was associated with
                      the fulvic and humic acid fractions; these were
                      quantitatively more important for the PAHs than the PCBs.
                      There appeared to be a high degree of association of
                      14C-activity with the mineral fraction following MIBK
                      separation of the humic fractions, ranging between 8 and
                      $52\%$ for C-14-PCBs and $57-80\%$ for C-14-PAHs. The
                      mineral (inorganic) component of the soils apparently played
                      a significant (previously unreported) role in the
                      sequestration of both PCBs 28 and 52 and the PAHs
                      fluoranthene and benzo[a]pyrene.},
