AB  - Forests are important compartments influencing the environmental fate of 
      persistent organic pollutants (POPs). To illustrate the effect of forests on the 
      regional cycle of POPs, a level IV fugacity fate and transport model coupled with 
      a detailed dynamic-forest module was applied to simulate the long-term variations 
      of PCB-153 in China, where forest coverage accounts for approximately one fifth 
      of land area. In the scenarios with forests, atmospheric outflow from China was 
      69% of that in the scenario without forests due to the enhanced storage in soil, 
      degradation, and leaching. Previous studies regarded high-latitude areas, such as 
      the polar region and boreal forests, as environments capable of reducing mobility 
      of PCB-153, and they act as sinks of POPs. This modeling result suggests that 
      tropical and subtropical forests may also play a similar role despite high 
      temperatures favoring volatilization. Unlike boreal forest, the low-latitude 
      forests may reduce the overall lifetime of PCB-153 in China due to enhanced 
      degradation in warmer and moist soils of the tropical and subtropical area. Given 
      that approximately half of the global forests are located in tropical and 
      subtropical regions, they can be important environments influencing the global 
      geochemical cycle and distribution of POPs, hence deserving more scientific 
      attention by modeling and empirical studies.
