Biomagnification of mercury and its relationship with selenium in sharks from the Mexican Pacific Ocean
Ofelia Escobar Sánchez, Felipe Galván-Magaña y Rene Rosiles Martínez
Mercury (Hg) is a highly toxic element that is bioaccumulated through the food web, mainly in top predators. However,selenium (Se) has been proposed as an element with protecti ve eff ects against the toxicity of mercury. The interacti onbetween these two elements is important to evaluate the risk associated with dietary exposure to mercury. In thisstudy, we determined the bioaccumulati on of mercury in sharks and the biomagnifi cati on through their main preyoff the western coast of Baja California Sur, Mexico. We sampled muscle ti ssue of fi ve shark species and their mainprey.
