Resumen: "Concentrations of seven metals (As, Cd, Cr, Cu, Pb, Ni, and Zn) were analyzed in 33 bone tissue samples of Antillean manatees (Trichechus manatus manatus) found dead in lagoons and rivers of Tabasco and Campeche in the Gulf of Mexico and Chetumal Bay in the Caribbean region. The concentrations of Cr, Cu, Pb, and Zn were significantly different between regions, with greater levels found in the Gulf of Mexico group than in the Mexican Caribbean group (p\0.05). Pb concentrations differed significantly between
adults and calves. No differences were observed between sexes. Metal concentrations detected in the manatee bones
were higher than most of those reported for bones in other marine mammals around the world. Future studies are necessary
to establish whether the metal concentrations represent a risk to the health of the species."
