AB  - Organisms have long been treated as receptors in exposure studies of 
      polychlorinated biphenyls (PCBs) and other persistent organic pollutants (POPs). 
      The influences of environmental pollution on organisms are well recognized. 
      However, the impact of biota on PCB transport in an environmental system has not 
      been considered in sufficient detail. In this study, a population-based 
      multi-compartment fugacity model is developed by reconfiguring the organisms as 
      populated compartments and reconstructing all the exchange processes between the 
      organism compartments and environmental compartments, especially the previously 
      ignored feedback routes from biota to the environment. We evaluate the model 
      performance by simulating the PCB concentration distribution in Lake Ontario 
      using published loading records. The lake system is divided into three 
      environment compartments (air, water, and sediment) and several organism groups 
      according to the dominant local biotic species. The comparison indicates that the 
      simulated results are well-matched by a list of published field measurements from 
      different years. We identify a new process, called Facilitated Biotic Intermedia 
      Transport (FBIT), to describe the enhanced pollution transport that occurs 
      between environmental media and organisms. As the hydrophobicity of PCB congener 
      increases, the organism population exerts greater influence on PCB mass flows. In 
      a high biomass scenario, the model simulation indicates significant FBIT effects 
      and biotic storage effects with hydrophobic PCB congeners, which also lead to 
      significant shifts in systemic contaminant exchange rates between organisms and 
      the environment.
