“…This information is useful but often very restricted because it does not consider the effect of intraspeci c variations in the human population (exposure rate, human weight, meal size, etc.) or long-term exposure to pollutants (Nikolić et al 2019). Because As and Cd are very toxic to humans, this information is doubtless useful as an early warning, especially for shing activities in these areas.…”

Concentrations of Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were detected in the muscle and gills of Prussian carp from three different freshwater ecosystems: isolated ponds and the South Morava River in Serbia, and Kopačko Lake in complex wetland ecosystem of the Kopački Rit Nature Reserve in Croatia. The main goals of the paper were to assess the concentrations of potentially toxic elements (PTEs) in the muscle and gills of Prussian carp (Carassius gibelio), to examine whether abiotic factors from three different freshwater ecosystems affect the accumulation of PTEs in fish tissues and to estimate the human health risk resulting from fish consumption. There were only six concentrations of PTEs in the gill tissue (Cr, Hg, Mn, Pb, Sn, and Zn) that were not significantly different among the different freshwater ecosystems. In the muscles, the differences were much less visible. Kopačko Lake distinguished with the highest values of metal pollution index (MPI) for muscles (0.24) and isolated ponds with the highest values of MPI for gills (0.8). The redundancy analysis (RDA) showed that concentrations of Al, Mn, Zn, Cu, and Fe in the gill tissue were significantly correlated with the environmental variables. In contrast, the RDA based on element concentrations in the fish muscles indicated no significant relationship with the environment. Isolated ponds, with no inflow of freshwater, stand out as the most polluted, followed by Kopačko Lake with occasional floods. Flowing freshwater ecosystem South Morava River can be single out as at least polluted with PTEs. The target hazard quotients (THQ) and hazard index (HI) suggested there were no significant noncarcinogenic health risks. The target carcinogenic risk factor (TR) for As and Pb confirmed there were no cancer risks related to human fish consumption. Since the elevated concentrations of toxic Cd and As in Prussian carp were estimated, an early warning should be assumed, especially for fishing activities in these areas.

“…Due to the diversity of nutritional requirements, food selectivity, and food availability of various fish species, their nutrition is closely related to their living environment [ 6 , 7 ]. The quality of water and bottom sediments as abiotic elements shaping the conditions in the aquatic ecosystem is of particular importance [ 8 , 9 , 10 , 11 ].…”

Heavy metals are introduced into water due to anthropogenic activities and can significantly affect an entire ecosystem. Due to their close integration with the water environment, fish are a sensitive indicator of contamination. In addition, fish is an important element in human diets, therefore, monitoring the concentrations of metallic contaminants in their meat is particularly important for food safety. This study aimed to assess the pollution of water ecosystems with selected toxic heavy metals in lakes Dratów, Czarne Sosnowickie, and Syczyńskie. The concentration of Pb, Cd, and Hg in water, sediment, and freshwater fish muscle tissue was determined, and a food safety assessment was performed. The analysis of water and sediments showed that the sediments were characterised by a significantly higher concentration of heavy metals. Presumably, this ecosystem element plays an important role in the uptake of heavy metal contaminants by fish whose levels were higher in planktonophagous and benthophagous fish species as compared to predatory fish. The food safety assessment showed that amounts of heavy metals in the muscle tissue posed no threat to the health of consumers ingesting that fish species, neither individually (THQ) nor collectively (TTHQ).

Pollution of Small Lakes and Ponds of the Western Balkans—Assessment of Levels of Potentially Toxic Elements

et al. 2021

View full text Add to dashboard Cite

Small lakes and ponds are among the most sensitive ecosystems, vulnerable to changes that have little or no effect on larger water bodies. Therefore this topic should be given more attention around the world. Anthropogenic impacts, which have been extensively researched in larger water bodies, have been barely examined in small lakes and ponds. Considering that most of the studies are related to lakes bigger than 50 ha, a significant knowledge gap was left regarding small lakes and ponds. The same situation is in the Western Balkans, where studies related to pollutants in small lakes and ponds are limited. This chapter presents an overview of studies related to the contamination of small lakes and ponds of the Western Balkans, with special reference to pollution with potentially toxic elements PTEs. Since massive fish mortality happened several times, an assessment of PTEs in fish species Carassius gibelio from small Aleksandrovac Lake in Serbia is presented. The results indicate that fish muscle (meat) was exposed to the lower pressure of PTEs pollution than liver and gills, suggesting that, despite massive fish mortality, there was no risk for human health by fish consumption.Keywords Small water bodies • Fish • Human health risk • Aleksandrovac Lake IntroductionSmall water bodies, including ponds and small lakes, are freshwater ecosystems of high ecological relevance [1]. They occur in practically all terrestrial environments,
