“…Specific bioaccumulation to organs has been reported with Hg tending to accumulate in higher concentrations in muscles, Cd and Zn in kidney, and Cu in liver (68). Similar tendencies have been confirmed in other reports (60) with fish eggs containing the highest Zn concentrations among all fish tissues.…”

The concentrations of trace elements in fish roes and the effect of processing conditions (karasumi-like or karashi mentaiko) were investigated in six commercial fish species from New Zealand. The studied elements were As, Cd, Cr, Cu, Hg, Pb, and Zn, and the roes were from the following species: chinook salmon ( Oncorhynchus tshawytscha), hoki ( Macruronus novaezelandiae), southern blue whiting ( Micromesistius australis), hake ( Merluccius australis), blue warehou ( Seriolella brama), and barracouta ( Thyrsites atun). The concentrations of As, Cd, Cr, Hg, and Pb in the roes were lower than literature values for fish muscles. Only Zn in barracouta roe and Cu in salmon roe and their products were relatively higher than the generally accepted levels in fish muscles and could be of safety concern. Hence, the consumption of barracouta and salmon roes among certain parts of the population needs to be monitored and assessed. Dry salting (karasumi-like) processing increased ( P < 0.001) the concentrations of the studied trace elements while salting fermentation (karashi mentaiko) processing tended to decrease the levels of trace elements. Fermentation may be a useful process to decrease the level of toxic trace elements.

“…Mercury distribution in lightly contaminated localities seems to take the following pattern: muscle > kidney > liver > gonads [26, 27]. Higher Hg concentrations in muscle compared to liver have been reported in fish from Otradovice, a lightly contaminated locality in the River Jizera [28]; in tissue of fish from some selected lightly contaminated ponds studied for metal concentrations in tissues [29]; and in European eel (Anguilla anguilla ) and brown trout ( Salmo trutta ) from the River Ferrerias in Spain (a lightly contaminated locality) [30]. …”

Tissue samples from 1,117 fish of 25 species were collected from 1991 through 1996 at 13 locations along the River Elbe. The principal indicator species were perch (Perca fluviatilis) (n=118), chub (Leuciscus cephalus L.) (n=113) and roach (Rutilus rutilus) (n=138). Mercury (Hg) concentrations in muscle and liver were determined by atomic absorption spectrometry. The liver/muscle index in three indicator species from heavily contaminated and lightly contaminated localities were significantly different. In fish from heavily contaminated localities, Hg was deposited preferentially in the liver (the depository for inorganic and organic forms of Hg), while in lightly contaminated areas, it was deposited preferentially in muscle.

“…Therefore, it is essential to regularly monitor any potential contamination of the environment and its impact on food chains to ensure food quality and safety (Svobodová et al 2002(Svobodová et al , 2004Andreji et al 2006a). One of the most closely monitored areas is the aquatic ecosystem where fish are regarded as the ultimate components of the food chain (Yilmaz 2006).…”

This replicated 4×2 factorial study investigated the bioaccumulation of selected metals (Mn, Pb, Zn, Hg and Cr) in four tissues (gills, liver, muscle and skin) of common carp (Cyprinus carpio) domiciled in two sites (upstream and downstream) of Indus River in Mianwali district of Pakistan. The data were statistically compared for the main effects of the site and fish organs and their interaction on the bioaccumulation pattern of these metals in fish organs at P<0.05. It appeared that the fish sampled from downstream had higher trace metals than the fish from upstream. Significant differences between fish organs were observed for these trace metals (P<0.001). The fish showed higher bioaccumulation of vital metals like Zn and lower bioaccumulation for the toxic metals like Pb. The gills had the highest metal load followed by liver, skin and muscles. High concentrations of Mn, Hg and Cr were observed in different fish organs as compared to the WHO and Federal Environmental Protection Agency standards for food fish. However, the mean concentration of Pb and Zn were under the permissible limits of food fish. It implies that higher levels of Mn, Hg and Cr in fish muscles would have detrimental effects on the health of fish consumers such as pregnant women, children and elderly people of this study area.
