“…Fe: 15.0 mg L −1 + Mn: 2.90 mg L −1 4. Fe: 15.0 mg L −1 + Mn: 6.25 mg L −1 control, no supplementation Concentrations were adjusted considering our preliminary study where the retention was investigated via rearing water [28]. In this work ten times the previously applied sublethal level of Fe and Mn was adjusted to investigate the potential accumulation effect of a toxic concentration range via the chosen aquatic food chain.…”

“…Depending on the form of the metal compound, uptake paths are through the permeable epidermis or via food ingestion. Since the entire body surface of the aquatic organism gets in connection with the contaminants the adverse effects on the outer epidermis, the digestive tract and the respiratory system may add [28].…”

“…Based on the pollution index of sediment samples, the studied oxbows were characterized by moderate levels of contamination for Fe and Mn, since the mean geochemical concentration in the upper level (0-10 cm) of floodplain sediments is exceeded for both elements (35.000 mg kg −1 for Fe 2 O 3 and 1000 mg kg −1 for MnO) [49] [50]. In our first study the Fe and Mn retention was investigated via the rearing water media [28], while in this paper the results of accumulation tendency through food ingestion is described. The elemental concentration of the indicator organisms was determined by microwave plasma atomic emission spectrometry (MP-AES), which is a new and cost-effective technique that can be adapted in the routine analysis of metal pollution.…”

In present study the effect of iron (Fe) and manganese (Mn) contamination was assessed by modeling a freshwater food web of water, zooplankton (Daphnia pulex), and zebrafish (Danio rerio) under laboratory conditions. Metals were added to the rearing media of D. pulex, and enriched zooplankton was fed to zebrafish in a feeding trial. The elemental analysis of rearing water, zooplankton, and fish revealed significant difference in the treatments compared to the control. In D. pulex the Mn level increased almost in parallel with the dose of supplementation, as well as the Fe level differed statistically. A negative influence of the supplementation on the fish growth was observed: specific growth rate (SGR%) and weight gain (WG) decreased in Fe and Mn containing treatments. The redundancy analysis (RDA) of concentration data showed strong correlation between the rearing water and D. pulex, as well as the prey organism of Fe- and Mn-enriched D. pulex and the predator organism of D. rerio. The bioconcentration factors (BCF) calculated for water to zooplankton further proved the relationship between the Fe and Mn dosage applied in the treatments and measured in D. pulex. Trophic transfer factor (TTF) results also indicate that significant retention of the metals occurred in D. rerio individuals, however, in a much lower extent than in the water to zooplankton stage. Our study suggests that Fe and Mn significantly accumulate in the lower part of the trophic chain and retention is effective through the digestive track of zebrafish, yet no biomagnification occurs.

“…The exact amount of two different initial masses (0.2 g and 0.5 g) were measured of the reference material on analytical balance (Precisa 40SM-200A), as well as two different sample preparation methods were compared. During the digestion in open system with conventional heating, samples were weighted into glass beakers and digested on an electric hot plate with 6.0 ml 65% (m/m) nitric acid (reagent grade, Merck) and 1.0 ml 30% (m/m) hydrogen peroxide (reagent grade, Merck) at 80 °C for 4 hours [20]. After digestion, samples were diluted with 1% (v/v) nitric acid (reagent grade, Merck and Milli-Q water) to a final volume of 10 ml.…”

ABSTRACT. In our research we investigate the accumulation extent of the inorganic contaminants accessing the aquatic food chain, including zooplankton and fish species through model experiments. In this paper we discuss the preliminary experiments considering the measurement of iron and manganese accumulated in Artemia sp. after hatched and reared in metal contaminated model media. The goal is to develop the sample preparation and analytical methods required for the determination of metals adsorbed in the studied organisms. We proved that rinsing the zooplankton organisms three times with 2 mL per grams (wet weight Artemia) of rinsing solution prior to the sample preparation process decreased the possibility of analytical error. European Reference Material of fish tissue (ERM ® -BB422) was used to validate the applied sample preparation and atomic spectrometric methods. The average recovery value for the measured elements by open system digestion with conventional heating was 96% and 92% with microwave digestion. With MP-AES 99% and 92% were gained, respectively. According to our results no significant difference occurred between the digestion in open system with conventional heating and microwave assisted digestion as well as the cost effective microwave plasma atomic emission spectrometry (MP-AES) proved to be appropriate for the routine quantitative analysis of adsorbed elements in zooplankton organisms and fish tissues.

“…Furthermore, toxic metals can reach the cell nucleus and cause mutagenesis [17]. Contamination of the marine environment has risen in the last years, and is correlated with exponential human population increase and therefore, with an upward trend in anthropogenic pressure, a fact that may harm all the aquatic ecosystems [2,6,[18][19][20][21]. With the exception of the organically-bound elements (hydrogen, carbon, nitrogen and oxygen), there are approximately 20 inorganic mineral elements which are considered to be essential to sustain animal life, including fish [1,2].…”

This study investigates the influence of gender in the bioconcentration of essential and nonessential elements in different parts of Black Sea turbot (Psetta maxima maeotica) body, from an area considered under high anthropogenic pressure (the Constanta City Black Sea Coastal Area in Romania). A number of 13 elements (Ca, Mg, Na, K, Fe, Zn, Mn, Cu, Ni, Cr, As, Pb and Cd) were measured in various sample types: muscle, stomach, stomach content, intestine, intestine content, gonads, liver, spleen, gills and caudal fin. Turbot adults (4–5 years old) were separated, according to their gender, into two groups (20 males, 20 females, respectively), and a high total number of samples (1200 from both groups) were prepared and analyzed, in triplicate, with Flame Atomic Absorption Spectrometry and High-Resolution Continuum Source Atomic Absorption Spectrometry with Graphite Furnace techniques. The results were statistically analyzed in order to emphasize the bioconcentration of the determined elements in different tissues of wild turbot males vs. females, and also to contribute to an upgraded characterization of the Romanian Black Sea Coast, around Constanta City, in terms of heavy metals pollution. The essential elements Mg and Zn have different roles in the gonads of males and females, as they were the only elements with completely different patterns between the analyzed groups of specimens. The concentrations of studied elements in muscle were not similar with the data provided by literature, suggesting that chemistry of the habitat and food plays a major role in the availability of the metals in the body of analyzed fish species. The gender influenced the bioaccumulation process of all analyzed elements in most tissues since turbot male specimens accumulated higher concentration of metals compared to females. The highest bioaccumulation capacity in terms of Ca, Mg, Na, Ni, As, Zn and Cd was registered in caudal fin, liver and intestine tissues. Also, other elements such as K, Fe, Cu and Mn had the highest bioaccumulation in their muscle, spleen, liver and gills tissues. The concentrations of toxic metals in Black Sea turbot from this study were lower in the muscle samples compared with the studies conducted in Turkey, suggesting that the anthropogenic activity in the studied area did not pose a major impact upon the habitat contamination.
