TI  - Regional dynamics of persistent organic pollutants (POPs) in the Pearl River 
      Delta, China: implications and perspectives.

AB  - The mass transport budgets of 1,1,1-trichloro-2,2-bis(chlorophenyl)ethane 
      (p,p'-DDT) and decabromodiphenyl ether (BDE-209) in the Pearl River Delta, South 
      China were calculated based on previously collected data. Residual p,p'-DDT, 
      mostly related to historical use, has largely settled into soil (780,000 kg), 
      while the soil BDE-209 inventory (44,000 kg) is considerably smaller. Conversely, 
      large amounts of BDE-209 currently used in numerous commercial products have 
      resulted in a much higher atmospheric depositional flux of BDE-209 (28,100 kg/yr) 
      relative to p,p'-DDT (310 kg/yr). The soil inventory of p,p'-DDT is predicted to 
      decrease to half of its current value after 22 years, and the percent area 
      containing soil p,p'-DDT at levels exceeding the effects range-medium (27 ng/g) 
      will decrease from 40% to 20%. Finally, soil BDE-209 inventory will reach an 
      equilibrium value of 940 tons in ~60 years, when BDE-209 levels in 50% of soil 
      will be above an equivalent risk guideline value (125 ng/g).
