“…show that the musculature is definitively tissue with the lowest contents of accumulated heavy metals, within the limits of Macedonian alimentary norms, while the highest concentrations of metal residuum were observed in the liver and the gonads. These results are in accordance with conclusions of many authors (Salanki et al, 1982, Stripp et al, 1990, Berningen and Pannanen, 1994) that the liver and kidneys are the target organs for the accumulation of metals in fish, which is explained with efficient regulatory mechanisms: elimination via faeces (Berningen and Pannanen, 1994), high metallothionein concentrations (which efficiently bind Cd and Pb thus serving as detoxificators) in the liver and kidneys, low affinity of SH muscle fibre groups to Pb and the fact that in fish, as well as in humans, only 1-6% Cd and up to 10% of other metals resorbed via bowel mucous reaches muscles (Ohti and Chtenior, 1991). Spry and Wiener (1991) even draw a conclusion that, unlike methyl-Hg, Pb and Cd do not accumulate in the skeletal musculature in significant concentrations, therefore contamination of fish with these metals presents no particular risk to human health.…”

“…Almost no data were available to compare muscle and whole body concentrations, and liver to whole body comparisons were rarely reported. Comparisons of slopes (Table 6) of the relationships between liver and muscle and indicated that the relationships were not consistent between this study and literature values for common carp and white sucker (Bendell-Young and Harvey, 1989;Bradley and Morris, 1986;Harrison and Klavercamp, 1990;Miklovics et al, 1985;Sreedevi et at., 1992;Stripp et at., 1990;Suresh et at., 1993). Only the slopes of the relationship between concentrations in the liver and muscle tissue for nickel were not significantly different (t-test, P < 0.05).…”

“…Although Mn in bony tissue can increase in fishes exposed to high concentrations of this element (Lockhart and Lutz ; Fraser and Harvey ; Moreau et al ), Bendell‐Young and Harvey () found that this relationship was not clearly defined because Mn is also homeostatically regulated. Direct relationships have been observed between water and skeletal concentrations of Zn, Pb, Ba, As, and Cd (Fraser and Harvey ; Moreau et al ; Bendell‐Young and Harvey ; Bengtsson et al ; Stripp et al ; Miller et al ; Kock et al ); however, Zn concentrations in vertebrae have also been observed to be influenced by genetic factors (Yamada et al ).…”
