AB  - There is concern over possible effects on ecosystems and humans from exposure to 
      persistent organic pollutants (POPs) and chemicals with similar properties. The 
      main objective of this study was to develop, evaluate, and apply the Nested 
      Exposure Model (NEM) designed to simulate the link between global emissions and 
      resulting ecosystem exposure while accounting for variation in time and space. 
      NEM, using environmental and biological data, global emissions, and 
      physicochemical properties as input, was used to estimate PCB-153 concentrations 
      in seawater and biota of the Norwegian marine environment from 1930 to 2020. 
      These concentrations were compared to measured concentrations in (i) seawater, 
      (ii) an Arctic marine food web comprising zooplankton, fish and marine mammals, 
      and (iii) Atlantic herring (Clupea harengus) and Atlantic cod (Gadus morhua) from 
      large baseline studies and monitoring programs. NEM reproduced PCB-153 
      concentrations in seawater, the Arctic food web, and Norwegian fish within a 
      factor of 0.1-31, 0.14-3.1, and 0.09-21, respectively. The model also 
      successfully reproduced measured trophic magnification factors for PCB-153 at 
      Svalbard as well as geographical variations in PCB-153 burden in Atlantic cod 
      between the Skagerrak, North Sea, Norwegian Sea, and Barents Sea, but estimated a 
      steeper decline in PCB-153 concentration in herring and cod during the last 
      decades than observed. Using the evaluated model with various emission scenarios 
      showed the important contribution of European and global primary emissions for 
      the PCB-153 load in fish from Norwegian marine offshore areas.
