“…Mercury is capable of atmospheric transport and is found even in water objects located at a great distance from industrial enterprises, especially in low-mineralized and acidified lakes. High degree of upsilting and bogginess of catchment basin, increased activity of microorganisms, low value of hydrogen ion exponent of aquatic environment and low growth rate of fish are main factors determining high level of mercury accumulation in muscles of fish from water objects that do not have local anthropogenic sources of mercury pollution [7].…”

“…At present time there is an active research and evaluation of the state of fishery water bodies of the Vologda Region (specialty water objects of the Chagodoshcha area (2018), the Ustyuzhna area (2018), etc.) and another studied region of Russia, such as the Tomsk Region (2018), the Republic of Karelia (2004), the Murmansk Region (2004, 2018), etc., with the use of identification of mercury concentration in different species of fish [4][5][6][7][8][9][10]. However, mercury level in piscifauna of some lakes and watercourses of the Vologda Region (for example, in fish of minor water objects of the Kirillov area, such as Svyatoye and Borovskoye lakes) is staying unknown.…”

Mercury is one of the most dangerous toxicants for all living organisms, having a high degree of biomagnification. The determination of mercury concentration in different species of fish is important for evaluation of the state of aquatic ecosystems. The aim of research is study of peculiarities of mercury content in fish of the Sheksna Reservoir, the Sukhona River, Kubenskoye, Borovskoye and Svyatoye lakes. Mercury concentration in fish muscles of the Vologda Region varies from 0.0397 mg/kg to 1.167 mg/kg of wet mass. The highest average of mercury content is established in the muscle tissue of river bass (0.477±0.202), and the lowest average is in the muscle tissue of eastern bream (0.133±0.082). Mercury level does not exceed maximum permissible concentration of heavy metal and weekly norm, harmless for a person weighing 70 kg in most of examined specimens. Сomparison of mercury content in muscles of fish from surveyed water bodies showed a significant difference between river bass and most non-piscivorous species, as well as between individuals of river bass from Svyatoye and Borovskoye lakes. We also revealed a reliable correlation dependence of mercury content in the muscle tissue on mass and length of body for samples of river bass, northern pike and silver bream. Values of mercury concentration in the muscle tissue of river bass from Lake Kubenskoye and the Sheksna Reservoir vary in process of time.

Quantitative assessment of microplastic content in the gastrointestinal tract of perch, roach and bream of Kubenskое Lake in the Vologda region was conducted. Microplastics were detected in 60% of bream specimens and 43% of perch specimens. No plastic microparticles were found in the gastrointestinal tract of the roach. It was found average number of microplastic particles was 1.6 ± 0.4 items per individual of bream, and 4.2 ± 1.4 items of microplastic per individual of perch. Microplastics in the gastrointestinal tract of fish were mainly represented by fibers with a small proportion of fragments and films. No significant differences (р 0.05) in the content of microplastics in the gastrointestinal tract of benthivorous (bream) and euryphage (perch) were found. The data obtained are the first evidence of the presence of microplastics in fish of the Vologda Oblast water bodies.
