Lead, cadmium and total mercury concentrations have been determined in the muscle of six fish species: roach (Rutilus rutilus L.), bream (Abramis brama L.), perch (Perca fluviatilis L.), pike (Esox lucius L.), vendace (Coregonus albula L.) and whitefish (Coregonus lavaretus L.) from selected lakes in North-Eastern Poland (Łańskie, Pluszne, Dłużek and Maróz), caught over the period October 1999 to...
Cadmium and lead were determined in the tissues of roe buck from the Polesie Lubelskie region using atomic absorption spectrometry (AAS). The determinations involved muscles, hearts, kidneys and livers. The samples were mineralized in the muffle furnace at 450°C. The content of the elements was determined after extraction to organic phase (4-methylpentan-2-one, MIBK) of its complex with ammonium pyrrolidindithiocarbamate...
This paper presents the results of a study on the content of Cu, Zn, Pb and Cd in livers and breast muscles of mallards obtained in Warmia and Mazury in 1999-2000. Samples from 32 mallards hunted in Łężany, Zembrze, Szestno and Nidzica, as well as samples from 7 pheasants and 6 mallards from the area of Śląsk were analyzed.
