	abstract = {The mass transport budgets of 1,1,1-trichloro-2,2-bis(chlorophenyl)ethane (p,p\&$\#$039;-DDT) and decabromodiphenyl ether (BDE-209) in the Pearl River Delta, South China were calculated based on previously collected data. Residual p,p\&$\#$039;-DDT, mostly related to historical use, has largely settled into soil (780,000 kg), while the soil BDE-209 inventory (44,000 kg) is considerably smaller. Conversely, large amounts of BDE-209 currently used in numerous commercial products have resulted in a much higher atmospheric depositional flux of BDE-209 (28,100 kg/yr) relative to p,p\&$\#$039;-DDT (310 kg/yr). The soil inventory of p,p\&$\#$039;-DDT is predicted to decrease to half of its current value after 22 years, and the percent area containing soil p,p\&$\#$039;-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).
