“…This is important because muscle constitutes the greatest mass of the fish that is consumed. This result is in good agreement with observations carried out on several wild and cultured fish species (Canli and Atli 2003;Usero et al 2004;Linde et al 2004;Ureña et al 2007;Ciardullo et al 2008).…”

The distribution and potential bioaccumulation of dietary and waterborne cadmium and lead in tissues of sea bream (Sparus aurata), a major aquaculture species, was studied in relation to three different fish farming systems. Metallothionein levels in fish tissues were also evaluated. Results demonstrate that metal concentrations in various tissues significantly vary among fish culture systems. Different tissues show different capacity for accumulating heavy metals. The content of both cadmium and lead is not strictly correlated with that of metallothionein. Indeed, the marked accumulation of both metals in liver, as well as the high lead content found in gills and kidney, are not accompanied by a concomitant accumulation of metallothioneins in these tissues. No correlation is present between heavy metals and metallothionein content in muscle tissue. The results also demonstrate that cadmium accumulates mainly via dietary food, whereas lead accumulation is not of food origin. Noteworthy is that the concentration of the two metals found in muscle in all instances is lower than the limits established by European Union legislation for fish destined for human consumption.

“…Significantly higher (P < 0.05) content of mercury was measured in dorsal muscles (Pilská 30.6 ± 5.0 µg/kg FW, Domaninský 72.4 ± 19.9 µg/kg FW, Matějovský 18.9 ± 2.0 µg/kg FW) than in the liver (Pilská 11.5 ± 2.5 µg/kg FW, Domaninský 18.9 ± 7.6 µg/kg FW, Matějovský 8.2 ± 2.0 µg/kg FW). This fact indicated the studied reservoirs (Pilská, Domaninský, and Matejkovsky reservoirs) as clean localities, in accordance with the studies by Svobodová et al (1995), Foster et al (2000), and Linde et al (2004). These authors demonstrated that in fish from heavily contaminated localities mercury was deposited preferentially in the liver, while in slightly contaminated localities it was preferentially deposited in muscle.…”

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.

“…The accumulation of Cd in the tissues were as follows: kidney > liver > testis > small intestine. Several authors reported that the organ of higher accumulation of Cd is kidney and also it is a detoxifying organ (Nad et al, 2005;Linde et al, 2004 andMassanyi et al, 2003). In our study also revealed high accumulation of Cd was observed in 30d Cd treated rat kidney (31.578±0.499 µg/g) and low level of Cd concentration was observed in small intestine Table 1.…”

Abstract:The present study is designed to investigate the accumulation of cadmium (Cd) in selected tissues such as liver, kidney, testis and small intestine of male albino rats treated for Cd and after combined supplementation with Zinc (Zn) + Iron (Fe) and Selenium (Se) + Copper (Cu). The wistar albino rats were treated with cadmium chloride(CdCl 2 )at a dose of 1/10 th LD 50 i.e. 22.5 mg / kg body weight for 7, 15 and 30 days(d) time intervals. After 15 d to Cd treatment, the rats were then supplemented with the above combination of two trace elements and then observed for accumulation of Cd at specific time intervals. These trace elements at a dosage of 1 mg/ kg body weight of Se, 16mg/kg body weight of Cu, 12 mg / kg body weight of Zn and 40 mg / kg body weight of Fe were given as supplements. There was significant Cd accumulation in liver and kidney among the selected tissues before to supplementation and there was significant decrease in the Cd accumulation levels in all the tissues after trace element supplementation. Moreover the 30d Zn + Fe supplemented rat kidney showed maximum decrease in Cd accumulation (8.327µg/g wet wt. of the tissue).
