AB  - There is growing worldwide recognition of the threat posed by persistent organic 
      pollutants (POPs) to wildlife populations. We aimed to measure exposure levels to 
      POPs in a Southern Hemisphere aquatic waterbird species, the nomadic gray teal 
      (Anas gracilis), which is found across Australia. We collected wings from 39 
      ducks harvested by recreational hunters at two sites (one coastal, one inland) in 
      Victoria, southeastern Australia, in 2021. We examined three groups of POPs: nine 
      congeners of polychlorinated biphenyls (PCBs), 13 organochlorine pesticides 
      (OCPs), and 12 polycyclic aromatic hydrocarbons (PAHs). The PCBs, OCPs, and PAHs 
      were detected at quantifiable levels in 13%, 72%, and 100% of birds, 
      respectively. Of the congeners we tested for in PCBs, OCPs, and PAHs, 33%, 38%, 
      and 100% were detected at quantifiable levels, respectively. The highest levels 
      of exposure to POPs that we found were to the PAH benzo[b]fluoranthene, occurring 
      at a concentration range of 1.78 to 161.05 ng/g wet weight. There were some 
      trends detected relating to differences between geographical sites, with higher 
      levels of several PAHs at the coastal versus inland site. There were several 
      strong, positive associations among PAHs found. We discuss potential sources for 
      the POPs detected, including industrial and agricultural sources, and the likely 
      role of large-scale forest fires in PAH levels. Our results confirm that while 
      Australian waterbirds are exposed to a variety of POPs, exposure levels are 
      currently relatively low. Additional future investigations are required to 
      further characterize POPs within Australian waterbird species. Environ Toxicol
