AB  - This study presents a comprehensive assessment of persistent organic pollutants 
      (POPs) in the blubber of a stranded blue whale found on the coast of Taiwan. The 
      analysis included polycyclic aromatic hydrocarbons (PAHs), polychlorinated 
      biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), Hexachlorobenzene (HCB), 
      and polybrominated diphenyl ethers (PBDEs). The whale exhibited evident signs of 
      emaciation, including low body weight, reduced blubber fat content, and thin 
      blubber thickness. The dominant fatty acid type detected in the blubber was 
      short-chain monounsaturated fatty acids (SC-MUFA), known to aid in 
      thermoregulation. Stable isotope ratios indicated that the blue whale occupied a 
      lower trophic position compared to a fin whale, suggesting its proximity to krill 
      habitats in the Southern Ocean for feeding. The average concentrations of DDTs 
      (1089.2 +/- 4.7 ng/g lw; SigmaDDT) and PCBs (1057.1 +/- 49.8 ng/g lw) in the blubber were 
      almost one order of magnitude higher than PAHs (41.7 +/- 10.0 ng/g lw), HCB 
      (70.6 +/- 2. ng/g lw), and PBDEs (7.2 +/- 1.2 ng/g lw). Pollutant concentrations in 
      this individual blue whale were comparable to levels found in Norway, higher than 
      those found in Chile, and notably lower than those found in Canada and Mexico. 
      Calculating the biomagnification factor (BMF) for the POPs from krill (Euphausia 
      superba) to the blue whale revealed significant bioaccumulation of pollutants in 
      this particular whale. Additional research is imperative to achieve a thorough 
      comprehension of bioaccumulation of POPs and their potential toxicological 
      impacts on whale health.
