“…Fish, as indicator organisms, are well suited for the monitoring of polluted aquatic ecosystems, since they are able to accumulate all the harmful substances from water and sediment as well as from the food chain [12][13][14]. Common carp (Cyprinus carpio L., 1758) is a world-wide freshwater fish species with relatively wide tolerance toward contamination and it is one of the most important farmed fish in Eastern Europe [15].…”

“…Several studies demonstrate that this phenomenon is present in fish; however, the diversity of its manifestation varies among species and depends on such factors as age, size (both weight and length), feeding habit and ecological requirements [28]. A previous experiment of Fehér et al (2013) revealed the interactive effect of cobalt treated water on the manganese and zinc adsorption of Lates calcarifer [12]. According to the literature data, it has also found that heavy metal accumulation in tissues of fish species show a certain tendency; however, the reasons and explanations are not yet clearly stated.…”

), 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.

“…Literature data is quite controversial: some suggest washing the organisms with distilled water [11] although it can cause the remove of the elements from the cells due to osmosis. Other papers mention seawater or tap water depending on the rearing media [12][13][14], however it can contaminate the samples; while not rinsing the zooplankton organisms at all can result in a positive measurement error.…”

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.

“…Before ICP-OES and MP-AES measurements, dried and homogenised samples were processed with microwave digestion in Teflon vessels (0.3 g dried sample ? a mixture of 5 ml 65 m/m % HNO 3 and 0.5 ml 30 m/m % H 2 O 2 ) to liberate their total P content (Rodushkin et al, 1999;Fehér et al, 2013). The resulting solutions were diluted with ultrapure 'Milli-Q' water prior to measurements.…”
