Mercury biomagnification in the Atlantic spotted dolphin Stenella frontalis food chain, using nitrogen stable isotope as an ecological tracer. Helena A. Di Beneditto 1 , Marcelo G. Almeida 1 , Carlos E. Rezende 1 , Salvatore Siciliano 3 , Jailson F. Tissue concentrations of Hg in a voracious predator fish, the largehead hairtail Trichiurus lepturus , one of the dolphin's prey, were 9. This fish species and the cephalopod showed the lowest median Hg concentration.

All links of the entire trophic chain presented trophic transfer of Hg with a biomagnification factor higher than 1.
