AB  - The continuous disposal of persistent organic pollutants (POPs) in South Africa 
      (SA) warrants concern about their detrimental effects on humans and wildlife. We 
      surveyed six dolphin species (n = 90) incidentally captured in shark net 
      installations or stranded off the SA east and south coast from 2005 to 2009 to 
      study the POP exposure. Sousa plumbea, an inshore and estuarine species, was 
      found to be the most contaminated by total POPs (21 100 ng g(-1) lw) of all the 
      dolphins off SA, followed by Tursiops aduncus (19 800 ng g(-1) lw), Lagenodelphis 
      hosei (13 600 ng g(-1) lw), and Delphinus capensis (5500 ng g(-1) lw), whereas 
      POP levels in the offshore or pelagic delphinids were much lower. In all 
      delphinids, dominant pollutants were dichlorodiphenyltrichloroethanes (DDTs), 
      which represented more than 60% of the total concentration of total POPs, 
      followed by polychlorinated biphenyls (PCBs, 30%). Concentrations of DDTs in 
      S. plumbea and T. aduncus off SA were among the highest levels reported in 
      delphinids globally. Approximately half of the adult T. aduncus had PCB 
      concentrations above the effect threshold for impairment of immune functions. The 
      concentrations of Mirex and Dieldrin in SA delphinids were higher than those 
      found in species from other regions of the Southern Hemisphere.
