TI  - HCB, p,p'-DDE and PCB ontogenetic transfer and magnification in bluefin tuna 
      (Thunnus thynnus) from the Mediterranean Sea.
PG  - 4227-33
AB  - The bluefin tuna, Thunnus thynnus (Linnaeus 1758), is biologically and 
      economically important in the Atlantic--Mediterranean ecosystems. Bluefin tuna 
      feed on diverse food items depending on their age, thus they occupy different 
      trophic levels during their lifespan. Hexachlorobenzene (HCB), p,p'-DDE and 
      polychlorinated biphenyls (PCBs) are well-known persistent organic pollutants 
      (POPs) in the Mediterranean basin. The relationship between stable isotopes of 
      nitrogen (N) and the POP residue levels in tissues has recently increased 
      knowledge on the link between the trophic levels and the contaminant 
      accumulation. Trophic levels were estimated by using 15N/14N ratio (delta15N) and 
      HCB, p,p'-DDE, and forty-three PCBs were quantified in bluefin tuna from the 
      southern Tyrrhenian Sea. Results showed that changes in PCB and p,p'-DDE 
      concentrations were a function of size and trophic level, while no correlations 
      were observed for HCB. Apart from HCB and PCB nos. 101, 207, 95, 158, and 60 + 
      56, which did not show any significant increase per trophic level, the other PCBs 
      and the p,p'-DDE increased significantly. The ontogenetic magnification factor of 
      PCBs was 6.6 +/- 0.5, which was significantly (12 times) higher (p < 0.05) than 
      the values found for p,p'-DDE (1.4) and HCB (1.4).
