abstract
Levels of metals (Ba, Cd, Co, Cu, Ni, Pb, V, Zn, Ag, Cr and Fe) in fish muscle of the Laguna de Pom-Atasta of Campeche, Mexico were determined. Most of the metals, except Ni, Zn and Fe were found in sub ppm (mg/kg dry weight) levels. Higher levels of Cd and Pb in fish muscle from this study displayed than have been observed in fish from other sites in the Gulf of Mexico area. However, concentrations of Cd and Pb were below the established metal concentrations in fish by the Health Secretariate of Mexico.
