AB  - The distribution and fractionation of persistent organic pollutants (POPs) in 
      different matrices refer to how these pollutants are dispersed and separated 
      within various environmental compartments. This is a significant study area as it 
      helps us understand the transport efficiencies and long-range transport 
      potentials of POPs to enter remote areas, particularly polar regions. This study 
      provides a comprehensive review of the progress in understanding the distribution 
      and fractionation of POPs. We focus on the contributions of four intermedia 
      processes (dry and wet depositions for gaseous and particulate POPs) and 
      determine their transfer between air and soil. These processes are controlled by 
      their partitioning between gaseous and particulate phases in the atmosphere. The 
      distribution patterns and fractionations can be categorized into primary and 
      secondary types. Equations are developed to quantificationally study the primary 
      and secondary distributions and fractionations of POPs. The analysis results 
      suggest that the transfer of low molecular weight (LMW) POPs from air to soil is 
      mainly through gas diffusion and particle deposition, whereas high molecular 
      weight (HMW) POPs are mainly via particle deposition. HMW-POPs tend to be trapped 
      near the source, whereas LMW-POPs are more prone to undergo long-range 
      atmospheric transport. This crucial distinction elucidates the primary reason 
      behind their temperature-independent primary fractionation. However, the 
      secondary distribution and fractionation can only be observed along a temperature 
      gradient, such as latitudinal or altitudinal transects. An animation is produced 
      by a one-dimensional transport model to simulate conceptively the transport of 
      CB-28 and CB-180, revealing the similarities and differences between the primary 
      and secondary distributions and fractionations. We suggest that the decreasing 
      temperature trend along latitudes is not the major reason for POPs to be 
      fractionated into the polar ecosystems, but drives the longer-term accumulation 
      of POPs in cold climates or polar cold trapping.
