“…Svobodová et al (2002) reported that the main organs for cadmium accumulation were liver and kidneys. The liver has the ability to accumulate large quantities of pollutants from the external environment, and also plays an important role in storage, redistribution, detoxification, and transformation of pollutants (Evans et al 1993). Higher concentrations of cadmium in fish tissues were found in 50 samples of carp liver mainly from Domaninský (17 samples, Cd 456.0 ± 204.4 µg/kg FW), Pilská (19 samples, Cd 115.0 ± 7.4 µg/kg FW) and Matějovský (14 samples, Cd 117.1 ± 1.2 µg/kg FW) reservoirs.…”

Toxic metals (cadmium, lead, and mercury) in the tissues of common carp fished from three reservoirs (Pilská, Domaninský, and Matějovský) in the Bohemian-Moravian Highlands were measured in the period from April 2013 to September 2014 and the risk of consuming the fish from these localities was evaluated. During this project 25 fish specimens from each locality were analysed. The concentration of metals in muscle tissue and liver was determined by atomic absorption spectrometry. A variation in the content of heavy metals in fish samples and fish tissues was demonstrated and discussed. Higher concentrations of cadmium in the fish tissue were found in 50 samples of carp liver. Because the fish liver is not commonly consumed, common carp from the Moravian-Moravian Highlands does not pose any health risk for consumers. Concentrations of the other monitored toxic metals in fish tissue were low and were complying with the maximum residue limit in all cases.

“…Fish samples are considered as one of the most indicative factors in freshwater systems, for the estimation of trace metals pollution potential (Evans et al 1993;Rashed 2001;Papagiannis et al 2004). Several studies have shown that metal accumulation can effect the wild species (Guhathakurta & Kaviraj 2000;Kargin 1998;Canli & Atli 2003;Papagiannis et al 2004;Fernandes et al 2007).…”

Atatürk Dam Lake is an important ecosystem located in south-eastern Anatolia in Turkey. In this study, concentration of Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined in kidney, liver, gill and muscle of Tor grypus which has great economic value in Atatürk Dam Lake. Heavy metal levels in fish samples were analyzed by inductively coupled plasma spectroscopy (ICP). The metal accumulation in the liver, kidney and gill of Tor grypus was found to be quite high in comparison to the muscle. All metal levels detected in tissues were the limits for fish proposed by FAO/ WHO, EU and Turkish Food Codes and safe within the limits for human consumption in the edible parts of fish species in the region.

“…This indicates dominance of detoxification over accumulation processes. Several studies have shown that the liver has the ability to accumulate large amounts of pollutants from the external environment and plays an important role in their storage, redistribution, detoxification and transformation (Evans et al 1993;Wiener et al 2003;Kwaśniak, Falkowska 2012). No fungicides were found in the liver.…”

The aim of this study was to estimate the residue of chlorinated pesticides in the edible fish caught in the Gulf of Gdańsk and in the Vistula Lagoon. The highest mean concentrations of total DDT were found in the muscles of salmon (331.45 ng g -1 lw.) and sabre carp (306.29 ng g -1 lw.) caught in the Vistula Lagoon, and in the muscles of cod (309.88 ng g -1 lw.) and herring (304.86 ng g -1 lw.) from the Gulf of Gdańsk. Moreover, it was discovered that the following were present in the muscles of fish: DDT metabolites (pp'-DDE and pp'-DDD isomers) as well as hexachlorobenzene and its metabolites and endrin, dieldrin, α-endosulfan isomers and methoxychlor. Pesticides concentrations were higher in the livers of fish than in the muscles, which proves that the removal of toxins from the fish systems dominates over their accumulation. Because no concentration limits for pesticides have been defined, consumer safety assessment of fish caught in the Southern Baltic and in the Vistula Lagoon is not possible. The authors, having
