Assessment of the Geochemical Background and Anthropogenic Load by Bioaccumulation of Microelements in Fish

Abstract

Comparative characteristic of several microelements (Ni, Cu, Sr, Al, Zn, Co, Mn, Pb, Cd, Hg, As) found in fish (case study of breams in the Volga basin reservoirs) is presented. Regularities of accumulation of these elements in fish depending on their concentration in the water are analyzed. Main disturbances in fish caused by the accumulation of microelements in their organs and tissues are considered.

Distribution of Essential and Toxic Elements in Pelecus cultratus Tissues and Risk Assessment for Consumer Health

“…The literature data and the results of our study show that the metal concentrations in fish tissues vary widely depending on the sampling area. It is known that heavy metal contents in aquatic organisms are influenced not only by the anthropogenic load on the water body, the concentration of elements, and the duration of exposure, but also by the hydrochemical factors of the aquatic environment, because the solubility of a number of trace elements located in hard-to-reach compounds in silts depends on the oxygen level, pH, and other environmental parameters [ 89 , 90 , 91 , 92 ].…”

Study of the Effect of Chemical Pollution with Coal-Fired Power Plant on the Fish of Lake Kenon (Trans-Baikal Territory, Russia)

“…The lack of advanced clean coal combustion technologies for coal-fired power plants results not only in atmospheric chemical pollution but also in the pollution of water ecosystems. Chemical pollutions change the quality of lake waters, accumulate in hydrobionts, and interfere with the biodiversity and structure of the lakes populations (Sunda, Guillard 1976, Nikanorov, Zhulidov 1991, Heaven et al 2000, Cardwell et al 2002, Tulonen et al 2006, Moiseenko et al 2005, Pastukhov 2012, Moiseenko, Gashkina 2020.…”

“…The research (Chale 2002) has shown that concentrations of trace metals of water were lower than that in fish tissues, which is consistent with our research. The self-cleaning ability from water ecosystems where aquatic organisms a purify waters polluted plays a role here (Moiseenko et al 2005, Alimov et al 2013. As compared to the aquatic environment, the contents of chemical elements in bottom sediments are an order of magnitude higher (Table 4).…”

“…In such reference ecosystems as Lake Baikal, the content of Cr in the muscles of fishes ranges from 0.3 to 0.86 mg kg −1 (vetrov et al 1989); in the ecosystem of Lake Kennebec (Maine, USA), the level of Cr in the muscles of P. fluviatilis ranges from 0.1 to 1.7 mg kg −1 of dry matter (Friant et al 1979), which was compared to our findings. Low concentration of Cr in the muscles of fishes is due to its higher accumulation in the systems of active metabolism (Moiseenko et al 2005). In the fish muscles in Lake Kenon, zinc is 2-4 times higher, and Cu is seven times lower, and are comparable in Pb content to those obtained (Ebrahimpour et al 2011(Ebrahimpour et al , younis et al 2015.…”

The relevance of the contemporary landscape-ecological and biogeochemical studies of the Ob floodplain

“…LF Shepeleva, ZA Samoilenko and GS Taran are the most known scientists studying the floodplain vegetation [44][45][46][47][48][49][50]. Animals and birds were studied by AM Adam, SS Moskvitin and AA Maksimov [51][52][53][54][55][56][57][58]. Many scientists (NF Vyltsan, GD Dymina, AV Ogorodnikova, AI Boynov, VN Tyurin and PS Kuzin) studied the floodplain resources and hydrological peculiarities and problems [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74].…”
