TI  - Accumulation and time trends (2003-2015) of persistent organic pollutants (POPs)

AB  - Accumulation of persistent organic pollutants (POPs) in marine mammals is of 
      great concern and is associated with declining populations. The concentrations of 
      polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and 
      polybrominated diphenyl ethers (PBDEs) were measured in blubber of finless 
      porpoises (Neophocaena asiaeorientalis) collected from Korean coastal waters in 
      2010 and 2015, to assess the concentrations, time trends, and ecotoxicological 
      effects. Among the POPs measured, DDTs were detected at the highest 
      concentrations, followed by PCBs and PBDEs. Significant age- and sex-dependent 
      accumulation of POPs was evident for porpoises collected in 2010, but not for 
      those collected in 2015. This finding may be a function of stabilization of POP 
      concentrations over time. In our study, accumulation patterns of POPs were 
      dependent on consumption patterns and physico-chemical properties of the 
      contaminants, and on the metabolism in the porpoises. Significant reductions of 
      POPs were found between 2003 and 2010, likely reflecting the impact of domestic 
      and global regulation of POPs. However, no changes in most POPs were found 
      between 2010 and 2015, suggesting a trend toward stabilization. Approximately 10 
      % and 27 % of porpoises exceeded previously proposed threshold levels for PCBs 
      and DDTs, respectively, implying a potential health risk.
