Citação: BELO, A.P.B. ; CASTRO, V.R.O. ; RODRIGUES, A.M. (2007) - Determination of some metal-ions in the bodies of black-bass (Micropterus salmoides) and tench (Tinca tinca) and from water reservoirs close to border of Portugal/Spain. Int. J. Agric. Biol. ISSN 1560-8530. Vol. 9, n.º 3, p. 408-411.
Resumo: The heavy metal (Zn, Cu, Mn, Fe, Pb, Cd) concentrations of muscle tissues of Micropterus salmoides and Tinca tinca from fresh water reservoirs and Fish Production Units situated in Portuguese and Spanish regions close to the border Portugal/Spain, were evaluated by atomic spectrophotometer absorption. Dried powders from these fishes were used to be calcinated followed by acid and atomic spectrophotometric metal analysis. Mean values in mg Kg1 wet weight of M. salmoides from ESA and Urra reservoirs were respectively the following: Cd(0.03 & 0.03), Cu(3.23 & 2.41), Fe(5.03 & 4.90), Mn(0.58 & 0.49), Pb(0.46 & 0.63) and Zn(6.73 & 7.01). The mean contents in mg kg1 wet weight in T. tinca from Casillas and Olivenza are, respectively the following: Cd(0.02 &0.04),Cu(1.30 & 1.47), Fe(3.92 & 6.41), Mn(0.26 & 0.59), Pb(0.29 & 0.99) and Zn(6.27 & 8.96). Is was concluded that these metallic concentrations are bellow the maximum permissible for a safety utilization of theses fishes in human nutrition.
