“…They found the following Fe concentration in different organs: in muscle 25 ± 11 mg kg −1 and in gills 269 ± 134 mg kg −1 which are similar to our results, but they measured only 103 ± 37 mg kg −1 Fe in liver. In the case of Cu c o n c e n t r a t i o n o f l i v e r, t h e y h a d s i m i l a r r e s u l t (9.8 ± 12.6 mg kg ), but their results were an order of magnitude less than in gills (214 ± 14 mg kg ) and in liver [31].…”

“…Based on these data, the Hungarian National Standard (MSZ12749) considers these wetlands toxic to Fe (>1.0 mg L ). Generally, the concentration of essential trace metals below or over the optimum level in water has negative effects on the fish size, depending on the concentration, species and the chemical elements [31]. Although fish uptake dissolved iron and manganese through the gills, the uptake is more efficient through diet.…”

), for rearing time of 49 days. The treatment with Fe and Mn did not have any effect on the survival data and individual body weight in the levels tested. The highest concentration of Fe and Mn was found in the liver and brain of carp juveniles, while the lowest concentration of these elements occurred in the muscular tissue and gills. The treatment where Fe and Mn were applied in the highest concentrations resulted in a statistically higher level of these elements in the brain, grills and muscle tissues. The treatment where only Mn was present in the highest concentration caused increased level of Mn only in the liver. We found metal accumulation in almost every organ; however, the applied concentrations and exposure time did not affect the survival and average body weight of carp juveniles.

“…Various species of fi sh can be bioindicators of contamination with heavy metals and others pollutants [16]. Feeding habits have a great infl uence on pollutants accumulation, especially regarding heavy metals in different fi sh species [17][18][19][20]. Additionally, in different fi sh species heavy metals can be deposited in various amounts in their tissues.…”

The aim of this study was the investigation of water, sediments and fi sh tissues contamination with heavy metals. All samples were taken from the Danube River in Belgrade region, a location upstream from Batajnica. Concentrations of Cd, Hg and Pb in water samples were not detected, while concentrations of Zn, Fe, Cu and As were in the range of 0.004 -0.330 mg L -1. Iron was the most deposited metal in sediment samples in contrast to water samples where all investigated metals were detected. For the purpose of heavy metals determination in fresh fi sh tissue, fi fteen samples of three different fi sh species, silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus carpio) and wels catfi sh (Silurus glanis) were collected. Concentrations of Pb, Cd, As and Hg were determined in the digestive tract, liver and muscle by absorption spectroscopy. The highest concentration of Pb was in the digestive tract in all three fi sh species, ranging from 0.036 to 1.518 μg g -1 , while Cd was mostly deposited in the liver. Concentrations of As were in the range of 0.36 -0.73 μg g -1 in Hypophthalmichthys molitrix, 0.013 -0.18 μg g -1 in Cyprinus carpio and 0.003 -0.005 μg g -1 in Silurus glanis tissues, while the content of Hg was equal in all tested tissues of carp. Concentrations of all metals were found to be present in the fi sh samples at different levels, but these values are under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia, so the fi sh meat is acceptable for the human consumption.

“…While some of these metals are essential in the biological activity of living organisms others are not but essential metals may be toxic for the biological activities of organisms above certain concentrations [16]. Heavy metals including both essential and non-essential elements have a particular significance in ecotoxicology, since they are highly persistent and have potential to be toxic to living organisms [17,30].…”

The river ecosystem serves as ultimate sink for myriads of xenobiotic all over the world with deleterious effects on the living biota within it. Histopathological alterations in kidney and liver of the catfish Clarias gariepinus (Burchell, 1822) were studied in River Galma, Zaria Nigeria. Twenty-five samples of Clarias gariepinus were exposed to the river ecosystem at the peak of rainfall in August, 2015 for 14 days at five stations along River Galma, using the cage system. Fish samples and controls from each station were subsequently harvested and transported to the laboratory for histopathological examination of liver and kidney. Results from photomicrographs of tissues from different stations revealed varying histopathological alterations which ranged from vacuolation, constrictions, necrosis and aggregations of cells to congestion of the blood vessels. These results indicated that River Galma is witnessing pollution. This calls for ameliorative measures by relevant authorities so as to protect aquatic life as well as the public from the toxic effects of aquatic environmental pollution.
