AB  - Information about pollution and its potential impact in Australian marine 
      wildlife is scarce. To fill this knowledge gap, our study investigated 
      concentrations of legacy pollutants as well as naturally produced methoxylated 
      polybrominated diphenyl ethers (MeO-PBDEs) in blubber, liver, kidney and muscle 
      of Indo-Pacific bottlenose dolphins (Tursiops aduncus) from two large inverse 
      estuaries in South Australia from 1989 to 1995 and 2009-2014. Our results show 
      that concentrations of most pollutant classes are relatively low compared to the 
      literature but at the higher end of the ranges reported for marine mammals in 
      Australia. Results for some individuals exceed toxicity thresholds indicative of 
      immunotoxicity in marine mammals. It is important to note that concentrations of 
      some compound classes, particularly PBDEs and polychlorinated biphenyls (PCBs), 
      increased over a time interval of 20 years thereby placing more individuals at 
      risk in recent years. Some of the highest concentrations of persistent organic 
      pollutants (POPs) were measured in juveniles, which may jeopardize their 
      development and the success of future generations. These results indicate that 
      legacy pollutants may play a role in the long-term health of T. aduncus and 
      should be included in biomonitoring efforts.
