“…The same results were also obtained by some other authors (Čelechovská et al 2007;Svobodová et al 2002;Has-Schön et al 2008). Cadmium has a very long elimination half-life, and thus it gets accumulated in large amounts in parenchymatose tissues (Cornelis et al 2005).…”

Concentrations of Metals in Tissues of Fish from the Věstonice Reservoir

The aim of the present work was to compare the distribution of selected metals in tissues of several fish species caught in the Věstonice reservoir. The hygienic quality of fish meat was assessed with respect to the mercury concentration. A total of 35 fish of the following species were caught: carp (Cyprinus carpio), bream (Abramis brama), asp (Aspius aspius), pikeperch (Sander lucioperca) and pike (Esox lucius). Samples of muscle, liver (hepatopancreas), kidney, gonads and gills were analyzed. Hg, Pb, Cd, Cu, Zn and Cr concentrations in fish tissues were determined by the AAS. The results showed that different metals differ in their affinity to different fish tissues (e.g. Cu -liver, Cd -kidney). Mercury concentrations along the food chain increase, i.e. higher mercury concentrations are found in predatory fish. Contrary to mercury, cadmium and lead concentrations do not show any increases along the fish part of food chain in surface water ecosystems. In predatory fish, lower concentrations of these metals were found than in nonpredatory fish species. Differences in concentrations between ovaria and testes were found only in Cu and Zn. To evaluate possible health risks of mercury concentrations for consumers, the risk index was calculated and maximum admissible amounts of muscle meat for consumption were determined. The results confirmed good hygienic quality of market-ready fish from the Věstonice reservoir. Predatory fish, non-predatory fish, heavy metals, AAS, risk indexThe rising living standards of human population take their toll in increasing loads to the environment with various contaminating substances that occur naturally at very low concentrations, or do not naturally occur at all. Besides metal manufacturing and processing, the sources of environmental metal contamination include industrial waste products, the burning of fossil fuels, and the use of metals by consumers. The increase in metal concentrations in the environment is further enhanced by their poor degradability resulting in metal accumulation in the soil, water sediments and the food chain (Svobodová et al. 1987).As the final link of the food chain in the aquatic environment, fish are an important indicator of contamination by a number of substances, including metals (Svobodová et al. 1996). Moreover, toxic metal concentrations in fish are monitored also in terms of food safety (Svobodová et al. 2004). First and foremost, the most closely monitored potentially toxic metals include mercury followed by cadmium and lead. In recent years, food safety has been a priority in EU member states. Hence, the large number of regulations targeting veterinary food hygiene that are being adopted mainly by the European Food Safety Authority (EFSA) and other organisations. At present, hygienic limits are determined by the highest acceptable levels of contaminants in foodstuffs in the Commission Regulation 1881/2006/EC as amended and Decrees 68/2005 Sb. and 305/2004 Sb. of the Ministry of Health. As far as fish as food animals are concerned, the m...

“…Fish consumption in the Czech Republic is very limited compared to coastal states, which may be why this seemingly insignificant source of arsenic in our diet has been omitted so far. To date, only a few studies have been published on the total content of arsenic in the meat of wild and farmed fish from the Czech Republic (see the investigation of chub [24], various fish living in Slezska Harta reservoir [25], carp [26,27], and trout [28]). Information about the arsenic species in food on the Czech market has not yet been published.…”

Total arsenic and water-soluble arsenic species were determined in canned fish bought in Graz (n = 6) and Prague (n = 8) with inductively-coupled plasma mass spectrometry and anion-exchange liquid chromatography. A difference in total arsenic content between samples from Prague (mean 3.4; standard deviation (s.d.) 1.2 mg kg -1 ) and Graz (mean 2.5; s.d. 0.7 mg kg -1 ) was not significant, however Prague samples differed in abundance of arsenobetaine (mean 83% of extractable arsenic; s.d. 16%) vs. Graz samples (mean 66%; s.d. 10%). No differences in total arsenic were caused by fish species (mackerel, sardine, herring, tuna) and origin (Northeast and Eastern-central Atlantic).

The aim was to evaluate the extent of pollution of the Svratka River with organochlorinated pollutants using the chub (Leuciscus cephalus) as a suitable bioindicator of the river contamination. The sum of 7 PCB congeners was found in range of 7.6-93.8 ng/g (with median of 31.7 ng/g) wet weight (ww), DDTs of 2.9-93.8 (29.9) ng/g ww, HCHs isomers of 0.1-5.3 (1.0) ng/g ww, HCB of 0.3-8.4 (2.2) ng/g ww and OCS of <0.1-0.5 (0.1) ng/g ww. Our results confirm predominance of metabolite DDE and higher-chlorinated PCB congeners and are comparable with similar studies and findings within the Czech Republic.
