AB  - A predictive model for gas-phase PCBs and trans-nonachlor over Lake Michigan has 
      been constructed and the resulting data examined for trends. In this paper, we 
      describe the model results to show how the magnitude and variability of a plume 
      of contaminants from the Chicago area contributes to a highly variable region of 
      net contaminant deposition over the entire lake. For the whole lake, gross annual 
      deposition of PCBs is approximately 3200 kg, although the net annual gas exchange 
      is not significantly different from zero. The data-driven model illustrates that 
      on a daily basis, the net exchange of persistent organic pollutants (POPs) can 
      change from net deposition to net volatilization depending on the area of plume 
      impact. These findings suggest that i) control of urban areas can accelerate the 
      rate of volatilization from lakes; and ii) release of POPs from urban areas is 
      largely a result of volatilization processes.
