Assessment of copper and zinc levels in fish from freshwater ecosystems of Moldova

Abstract

The fish represent one of the most indicative factors for the estimation of trace metals pollution in freshwater systems and this is important not only for monitoring purposes, but also for the fish culture ones.

Seasonal Investigation of Selected Mineral Contents in Meat, Gills, and Liver of Perch (Perca fluviatilis L.) from Western Poland

“…Szefer et al [37], and Zubcov et al [14]. The same results were observed by Yazdi et al [29] for Cu determined in the tissues of Ctenopharyngo idella and Perca fluviatilis, and for Zn determined in the tissues of Perca fluviatilis.…”

“…Muscles are not always a good indicator of overall fish metal contamination, and therefore it is important to analyze other tissues, such as the liver and gills [5]. Although the muscle is not an active tissue in accumulating metals, it is commonly analyzed in literature because it is the main fish part consumed by humans [12,14]. Gills and liver are chosen as target organs for assessing metal accumulation.…”

Assessment of Trace Elements in Tissues of Fish Species: Multivariate Study and Safety Evaluation

“…12, 2016 in metabolism, including gill, liver and kidney tissues, are known to accumulate greater amounts of trace elements than muscle. [7][8][9][10] The pattern of trace elements distribution is usually evaluated using univariate procedures, but the use of multivariate pattern recognition techniques such as principal component analysis (PCA) and hierarchical cluster analysis (HCA) can provide further interpretation of results. PCA and HCA are multivariate analysis techniques commonly employed in the evaluation of food data allowing the establishment of similarities and differences in a data set.…”

Biological and Physico-Chemical Evaluation of the Eutrophication Potential of a Highly Rated Temperate Water Body in South – Eastern Romania

“…The spatial and temporal patterns of heavy metals such as Sr, Rb, Pb, Zn, Cu, Fe and Mn in aquatic systems have been linked to industrial and agricultural setups as the case of lake Geneva and Lucerne in Europe and could be similar to the lake Brates as presented on Tables 2 and 3 (Thevenon et al , Zubcov et al 2012. Climate sensitive processes such as catchment erosion and melt water runoff could also influence the high concentrations of Pb and other components in the soil and water (Liu et al 2012) of Lake Brates.…”

“…Previous studies on the water bodies of the region, performed by teams including scientists from Romania and the Republic of Moldova, have indicated that the quality of the water on both sides of the border (i.e. River Prut, Lake Stanca-Costesti, Lake Dubasari) is still far from the desired level, although the European environmental directives have been progressively implemented in the Romanian legislation since more than 10 years ago (Cioroi et al 2012;Zubcov et al 2012). As a result, the water of the Danube River and of the Danube Delta Biosphere Reserve is consequently affected (Ene et al 2010;Pantelica et al 2012;G.…”
