AB  - Investigating environmental pollution is important to understand its impact on 
      endangered species such as green turtles (Chelonia mydas). In this study, we 
      investigated the accumulation and potential toxicity of selected persistent 
      organic pollutants (POPs) and naturally occurring MeO-PBDEs in liver, fat, kidney 
      and muscle of turtles (n = 30) of different gender, size, year of death, location 
      and health status. Overall, POP concentrations were low and accumulation was 
      highest in liver and lowest in fat which is likely due to the poor health of 
      several animals, causing a remobilization of lipids and associated compounds. 
      PCBs and p,p'-DDE dominated the POP profiles, and relatively high MeO-PBDE 
      concentrations (2'-MeO-BDE 68 up to 192 ng/g lw, 6-MeO-BDE 47 up to 79 ng/g lw) 
      were detected in all tissues. Only few influences of factors such as age, gender 
      and location were found. While concentrations were low compared to other marine 
      wildlife, biological toxicity equivalences obtained by screening the tissue 
      extracts using the micro-EROD assay ranged from 2.8 to 356 pg/g and the highest 
      values were observed in muscle, followed by kidney and liver. This emphazises 
      that pollutant mixtures found in the turtles have the potential to cause 
      dioxin-like effects in these animals and that dioxin-like compounds should not be 
      overlooked in future studies.
