Determination of Heavy Metals in Roach (Rutilus rutilus) and Bleak (Alburnus alburnus) in Zhrebchevo Dam Lake

The aim of this study was to examine the concentration of iron (Fe), nickel (Ni), lead (Pb), manganese (Mn), copper (Cu), chromium (Cr), cadmium (Cd) and zinc (Zn) in roach (Rutilus rutilus) and bleak (Alburnus alburnus) as species for human consummation. Two fresh water fish species, roach and bl...

Two fresh water fish species, roach and bleak were caught from Zhrebchevo Dam Lake in Bulgaria. Determination of heavy metals (Fe, Cu, Ni, Pb, Zn, Mn, Cr and Cd) in muscle samples were performed with electrothermal atomic absorption spectrometry (ETAAS). The heavy metal content in the meat of roach and bleak were found to be 0.59±0.032 - 0.69±0.128 mg kg-1 for Cu, 6.59±0.224 - 7.34±0.142 mg kg-1 for Fe, 0.03±0.025 - 0.04±0.012 mg kg-1 for Ni, 0.06±0.044 - 0.07±0.031 mg kg-1 for Pb, 4.05±0.263 - 5.46±0.388 mg kg-1 for Zn, 0.49±0.060 - 0.72±0.080 mg kg-1 for Mn, 0.09±0.036 - 0.1±0.045 mg kg-1 for Cr, 0.01±0.002 - 0.01±0.003 mg kg-1 for Cd. The data show that the differences between the content of Fe, Cu, Mn, Zn, Cr and Ni in roach and bleak are significant, while these ones of Pb and Cd are not significant. The significant differences in the content of heavy metals in muscles of roach and bleak are as a result of multiple factors, including season, food, chemical properties of water or sediment. The data established during the investigation show that the edible part of fish do not carry heavy metals loads and concentrations are below the legal value for fish and fish products established by the Food and Agriculture Organization and national legislation.
