Metals in edible fish from Vistula River and Dead Vistula River channel, Baltic Sea.

VISTULA Lagoon (Poland & Russia); POLAND; RUSSIA; BALTIC Sea

Metals including Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, Pb, Sr and Zn were determined in muscle tissue of 12 fish species by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and cold vapour-atomic absorption spectroscopy (CV-AAS). Fish were collected from Vistula River at lower course and Dead Vistula River channel in south of Baltic Sea in Poland. The fish species examined include Round Goby (Neogobius melanostomus), Crucian Carp (Carassius carassius), Bull-rout (Myoxocephalus scorpius), Tench (Tinca tinca), Bream (Abramis brama), Burbot (Lota lot), Perch (Perca perca), Roach (Rutilus rutilus), Silver Carp (Hypophthalmichthys molitrix), Pikeperch (Stizostediun lucioperca), Brown salmon (Salmo trutta m. Trutta) and Eel (Anguilla anguilla). The median values of metal concentrations in fresh muscle tissue of 11 fish species varied as follows: Al < 0.5–60; Ba < 0.05–0.31; Ca 120–1800; Cd < 0.05–0.096; Co < 0.10; Cr < 0.10–0.50; Cu < 0.15–0.77; Fe 1.5–21; Hg 0.0058–0.65; K 1800–4200; Mg 130–560; Mn 0.12–0.59; Na 350–840; Ni < 0.2–0.31; Pb < 0.75; Sr 0.079–2.9; Zn 3.3–23 μg/g fresh weight. The Target Hazard Quotient (THQ) values calculated in this study for Cd and Hg from muscles of fish species collected from Vistula River were low in the range of 0.4 for Hg and 0.8 for Cd.
