TI  - Distribution of aged 14C-PCB and 14C-PAH residues in particle-size and humic 
      fractions of an agricultural soil.
PG  - 6575-83
AB  - Organic matter is considered to be the single most importantfactor limiting 
      availability and mobility of persistent organic pollutants (POPs) in soil. This 
      study aimed to characterize the distribution of 14C-PCB (congeners 28 and 52) and 
      14C-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 14C-activity. Soils were also 
      fractionated according to three particle sizes: >20, 20-2, and <2 microm. 
      Relative affinity values of 14C-activity for the different particle sizes varied 
      in the order 20-2 microm > (<2 microm) approximately (>20 microm) for the PCBs. 
      Relative affinity values of 14C-activity for the different particle sizes varied 
      in the order 20-2 microm > (<2 microm) > (>20 microm) for the PAHs. The 
      distribution of 14C-PCB or 14C-PAH residues in the organic and inorganic matrixes 
      of the particle-size fractions was determined using methyl isobutyl ketone 
      (MIBK). 14C-PCB and 14C-PAH-associated activities were primarily located in the 
      humin fraction of the 20-2 and <2 microm particle-size 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 
      14C-PCBs and 57-80% for 14C-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.
