TI  - Persistent organic pollutants (POPs) and per- and polyfluoroalkyl substances 
      (PFASs) in liver from wild and farmed tilapia (Oreochromis niloticus) from Lake 
      Kariba, Zambia: Levels and geographic trends and considerations in relation to 
      environmental quality standards (EQSs).

AB  - The current study was carried out to investigate a wide variety of persistent 
      organic pollutants (POPs) in wild and farmed tilapia (Oreochromis niloticus) in 
      Lake Kariba, Zambia, and assess levels of POPs in relation to Environmental 
      Quality Standards (EQSs). Concentrations of organochlorine pesticides (OCPs), 
      polychlorinated biphenyls (PCBs), polybrominated diphenyls (PBDEs), and 
      perfluoroalkyl substances (PFASs) were determined in liver samples of tilapia. 
      PFASs compounds PFOS, PFDA and PFNA were only detected in wild fish, with the 
      highest median PFOS levels in site 1 (0.66 ng/g ww). Concentrations of POPs were 
      in general highest in wild tilapia. The highest median  summation operatorDDTs (93 and 81 ng/g lw) 
      were found in wild tilapia from sites 1 and 2, respectively 165 km and 100 km 
      west of the fish farms. Lower DDE/DDT ratios in sites 1 and 3 may indicate 
      relatively recent exposure to DDT. The highest median of  summation operator(17)PCBs (3.2 ng/g lw) 
      and  summation operator(10)PBDEs (8.1 ng/g lw) were found in wild tilapia from sites 1 and 2, 
      respectively. The dominating PCB congeners were PCB-118, -138, -153 and -180 and 
      for PBDEs, BDE-47, -154, and -209. In 78% of wild fish and 8% of farmed fish 
       summation operator(6)PBDE concentrations were above EQS(biota) limits set by the EU. This warrants 
      further studies.
