AB  - Sea turtles are susceptible to environmental pollution, since many harmful 
      effects have been reported for different chemicals over the last two decades. In 
      this context, persistent organic pollutants (POPs), such as polychlorinated 
      biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are of particular 
      concern due to their endocrine-disrupting nature. The aims of this study were to 
      provide additional baseline data on PCB and PBDE concentrations in eggs of 
      Dermochelys coriacea; and to investigate whether any of the congeners could 
      compromise reproductive success in this species. A total of 18 nests from 
      different females were studied during the nesting season of 2008 at Reserva 
      Pacuare Beach, in the Caribbean side of Costa Rica. Reproductive parameters 
      (viability, fertility and hatching rates) were calculated for all nests and 
      hatchling morphometrics were successfully measured in 8 of them. Two to three 
      fresh eggs per nest were taken for contaminant study. Different congeners of POPs 
      were purified and identified using gas chromatography (GC) coupled to an ion trap 
      detector (GC-ITD MS/MS), as described below. Mean +/- SD concentrations were 
      calculated for POP congeners within each nest and clustering was also evaluated. 
      Correlations were performed searching for potential relationships with 
      reproductive parameters. POP levels were similar to those reported in 
      French-Guiana populations and slightly lower than those associated to Florida 
      populations. Sum of PBDEs showed a negative correlation to the hatching success, 
      suggesting potential harmful effects of these contaminants on the reproduction of 
      leatherbacks.
