AB  - Temporal trends in exposure to persistent organic pollutants (POPs) were assessed 
      in 22 pooled samples gathered from 69 individuals of Baltic ringed seal (Pusa 
      hispida botnica) from 1974 to 2015. Samples were analysed for polybrominated 
      dibenzo-p-dioxins and furans (PBDD/Fs), polychlorinated dibenzo-p-dioxins and 
      furans (PCDD/Fs), polybrominated diphenyl ethers (PBDEs) and polychlorinated 
      biphenyls (PCBs). No previous study has reported on the occurrence of PBDD/Fs in 
      marine mammals in the Baltic Sea. Concentrations of pollutants in Baltic ringed 
      seal, a marine mammal and top predator, can be used as an indicator of pollutants 
      concentrations in the Baltic region. Visual inspection of data did not show any 
      temporal trends for PBDD/Fs, while the PCDD/Fs and PCBs showed decreasing 
      concentrations between 1974 and 2015. PBDEs increased until the end of the 1990s 
      and then decreased until the end of the period.  summation operatorPBDD/Fs ranged from 0.5-52.3pg/g 
      lipid weight (l.w.) (0.08-4.8pgTEQ/g l.w.), with 1,2,3,4,6,7,8-HpBDF contributing 
      on average 61% to  summation operatorPBDD/Fs.  summation operatorPCDD/Fs ranged from 103 to 1480pg/g l.w. 
      (39-784pgTEQ/g l.w.), with 1,2,3,6,7,8-HxCDD, 1,2,3,7,8-PeCDD and 2,3,4,7,8-PeCDF 
      showing the highest average concentrations. PBDD/F toxic equivalents (TEQ) 
      contributed on average 1.1% to the total (PBDD/F+PCDD/F) TEQ. The  summation operatorPBDEs 
      concentration range was 18.7-503ng/g l.w., with BDE #47 the predominant congener. 
      The concentration range for  summation operatorPCBs was 2.8-40.1mug/g l.w., with #138 and #153 the 
      most abundant congeners. Visual inspection of the data showed decreasing 
      concentrations for all compound groups except PBDD/Fs. A slight increase in the 
      PBDD/Fs concentrations was observed from 2004 onwards. This observation needs to 
      be investigated further.
