AB  - Indo-Pacific humpback dolphins (Sousa chinensis) are apex predators in the Pearl 
      River Estuary waters (PRE) of China. PCBs, DDTs and other organochlorine 
      pesticides (OCPs) (e.g., HCHs, HCB, mirex and dieldrin) were analysed in blubber 
      samples of 45 dolphins and 10 prey fishes of S. chinensis collected from 2004 to 
      2013 in the PRE region to investigate the bioaccumulation and potential 
      biomagnification of persistent organic pollutants (POPs). DDTs were the most 
      abundant residue in the dolphins, with an average of 6,2700 ng g(-1) wet weight 
      (ww), followed by PCBs (average: 1,790 ng g(-1) ww) and other OCPs including 
       summation operatorHCHs, mirex, endrin,  summation operatorchlordanes, HCB, dieldrin, aldrin, heptachlor, and 
      pentachlorobenzene. The concentrations of PCBs and DDTs in male dolphins 
      significantly increased with age and length. In contrast, female dolphins did not 
      show obvious bioaccumulation trends with age and body length, possibly due to the 
      lactational and parturitional transfer of these compounds. Compared with the POP 
      residues in the prey fishes, the concentrations of PCBs, DDTs, and HCHs in the 
      dolphin blubber increased by factors of 99, 212, and 5, respectively, whereas the 
      residue levels of the other OCPs increased 2-185 times, indicating a potentially 
      significant biomagnification in the top predators. The potential biomagnification 
      factors calculated for most POPs were significantly higher than those in the 
      cetacean species from other regions.
