Abstract: Concentrations of As, Cu, Fe, Hg, Pb and Zn and activity concentrations from 234,238 U and 210 Po in water, fillet, liver and gills were determined in three stocked fish species from the Luis L. Leon reservoir, located in Northern Mexico. The considered species were Lepomis cyanellus , Cyprinus carpio and Ictalurus furcatus . 238 U and 234 U activity concentration (AC) in fillet samples showed values of 0.007–0.014 and 0.01–0.02 Bq?kg ?1 wet weight (ww), respectively. Liver samples for L. cyanellus , C. carpio and I. furcatus present 210 Po AC of 1.16–3.26, 0.70–1.13 and 0.93–1.37 Bq?kg ?1 ww. Arsenic, mercury and lead concentration intervals in fillet samples were 0.13–0.39, 0.005–0.126 and 0.009–0.08 mg?kg ?1 ww, respectively, while in gill samples they were 0.11–0.43, 0.002–0.039 and 0.02–0.26 mg?kg ?1 ww. The elemental Bioaccumulation Factor (BAF) for fish tissues with respect to their concentrations in water was determined. L. cyanellus showed the highest BAF values for As and total U, being BAF As = 37 and 40 L?kg ?1 in fillet and gills, respectively, and BAF U total = 1.5 L?kg ?1 in fillet. I. furcatus showed the highest BAF values for Hg and Pb, being BAF Hg = 40 and 13 L?kg ?1 in fillet and gills, and BAF Pb = 6.5 and 22 L?kg ?1 in fillet and gills, respectively. Some metal(loid) concentrations are slightly higher than European regulations for fish fillets. The difference in concentrations of metal(loid)s in fillet among the studied species is probably due to their differences in diet and habitat.
