“…These metals are bioaccumulated in the liver for detoxication. There is a risk of metallothionein synthesis in the fish body, which can cause another increase of these metals concentration in fish body as Hogstrand et al (1991) describe in perch, Olsvik et al (2001) in brown trout in Norwegian rivers and Linde et al (1999 and in brown trout in Spain. As our ichthyological research in the Louãka River shows, the occurrence of individuals older than 3 years is rare, and the analyzed fish were purely in the age of 2+ and 3+ (Table 3).…”

Vítek T., P. Spurn˘, J. Mare‰, A. Ziková: Heavy Metal Contamination of the Louãka River Water Ecosystem. Acta Vet Brno 2007, 76:149-154. Heavy metal contamination of the Louãka River water ecosystem was assessed in July 2005. We analyzed concentrations of T-Hg (total mercury), Cd, Pb, Cr, Cu, Zn, and Ni in water, sediments, zoobenthos, and in the brown trout (Salmo trutta m. fario) muscle and liver tissues (a total of 28 individuals) at four sampling sites. The highest Pb and Ni concentrations (4.634 -12.050 and 0.689 -24.980 mg·kg -1 ) were found in sediments. The zoobenthos was most contaminated by Zn and Cu (0.556 -1.505 and 2.925 -74.300 mg·kg -1 ). The heavy metal contamination of river water was highest in Ni and Cr (0.1 -6.8 and 0.5 -10.0 mg·l -1 ). Concentrations of heavy metals in the brown trout muscle were following (in mg·kg -1 ): Pb 0.108 ± 0.073 -1.010 ± 0.506, Cd 0.003 ± 0.002 -0.026 ± 0.022, Zn 3.956 ± 0.371 -5.801 ± 1.718, Ni 0.058 ± 0.018 -0.102 ± 0.046, Cr 0.028 ± 0.005 -0.073 ± 0.039, Cu 0.329 ± 0.079 -0.437 ± 0.064 and Hg 0.065 ± 0.008 -0.106 ± 0.047. Statistical differences (P < 0.05) in the brown trout muscle were in Pb and Zn. Cd, Cu and Zn were markedly accumulated in the brown trout liver (concentrations 0.107 ± 0.066 -0.223 ± 0.078, 59.973 ± 38.951 -145.800 ± 48.286 and 30.671 ± 3.574 -34.274 ± 7.226 mg·kg -1 ). Humans of 60 kg body mass may consume 1.5 kg of brown trout muscle from the Louãka River weekly without any risk. Adverse influence of the Uniglas distillery on the Louãka River environment contamination by heavy metals was not confirmed.

“…In previous reports, MT gene mRNA expression has often been proposed as a sensitive and efficient biomarker for evaluating the cumulative biological effects of metal exposure in the tissues of a wide range of aquatic species, e.g., the common carp (C. carpio) (Hermesz et al, 2001), brown trout (Salmo trutta) (Linde et al, 1999), and gudgeons (G. gobio) (Knapen et al, 2007). Further, it was considered useful for evaluating metal exposure in both laboratory and field studies (Viarengo et al, 1999;Fernandes et al, 2008) by using either common RT-PCR or real-time PCR.…”

“…granules). The study on salmonid fish, brown trout (Salmo trutta), and anguillid fish, European eel (Anguilla anguilla), in unpolluted Pigueña River in Spain revealed that in contrast to Cd, Cu and Zn, which were found in high percentages in hepatic cytosol, Pb was mainly located in the noncytosolic fraction (Linde et al 1999). Although whole tissue burdens can be good indicators of overall accumulation of metals in specific tissues, they are often not conclusive in understanding metal pollution impacts on aquatic organisms (Clements and Rees 1997;Farag et al 1999).…”

The possibility of direct measurement of trace elements in hepatic cytosol of European chub (Squalius cephalus) by HR ICP-MS after cytosol dilution with Milli-Q water and subsequent acidification was investigated. Due to low detection limits of this procedure, determination of 13 elements (As, Cd, Co, Cu, Fe, Mn, Mo, Pb, Sb, Sn, Sr, V, Zn) was possible in the chub hepatic cytosol, exhibiting excellent measurement repeatability in duplicates. Some of these elements were also measured by HR ICP-MS in acid digested cytosols (Cd, Co, Cu, Fe, Mn, Mo, Sr, V, Zn). Good agreement of the results obtained after sample dilution and sample digestion indicated that complex organic matrix of hepatic cytosol did not affect measurement reliability. Cytosolic concentrations of 13 trace elements in the chub liver were quantified in the following order:Fe,Zn>Cu>Mn>Mo>Sr,V,Cd>Co>As,Pb>Sn>Sb. Unlike Cd, Cu, Fe, Mn and Zn for which the cytosolic concentrations were previously reported after measurement by AAS, cytosolic concentrations of eight additional trace elements characteristic for the liver of chubs inhabiting the low contaminated river water were reported here for the first time (ng g -1 ): Mo 136. and Sb 0.9-2.6. The simultaneous measurement of large number of trace elements in the cytosolic fractions of fish tissues, which comprise potentially metal-sensitive sub-cellular pools, could be beneficial as a screening tool in the monitoring of natural waters, because it would enable timely recognition of increased fish exposure to metals.
