AB  - Coastal seas are important pools of persistent organic pollutants (POPs) 
      discharged from land. Considering the complex conditions in coastal seas and 
      various biochemical features of POPs, special temporal-spatial variations in POPs 
      have been reported. To understand these variations, we developed a 
      three-dimensional hydrodynamic-ecosystem-POP coupled model and applied it to the 
      Yellow Sea. We selected two POP species (polychlorinated biphenyl congener 153 
      (PCB-153) and decabromodiphenyl ether (BDE-209)), which have different 
      biochemical properties, as target materials. The dissolved PCB-153 simulated 
      concentration was high in late spring and low in autumn, whereas that of BDE-209 
      was high in summer and low in winter. Both PCB-153 and BDE-209 showed high 
      particle-bound concentrations in early spring. In summer, dissolved PCB-153 
      accumulated at the sea bottom, whereas dissolved BDE-209 accumulated at the sea 
      surface. Seasonal and spatial variation differences in the two POPs are likely 
      caused by greater Henry's Law Constant (H(')) and bioconcentration factor (BCF) 
      of PCB-153 than that of BDE-209, which leads to higher volatilization and 
      stronger absorption by the particles for PCB-153 than BDE-209. As a component of 
      such differences, the "biological pump" of PCB-153 in the central Yellow Sea is 
      more apparent than that of BDE-209.
