“…Due to anthropogenic pressure and a positive water balance, the Baltic has become one of the most polluted seas in the world. The main pathways of chemical substance flux to the region are rivers, along with other sources such as atmospheric deposition, diffuse runoff from land, industrial waste, shipping accidents, and wastewater treatment plants [3]. Additionally, submarine groundwater discharge (SGD) has recently been recognized as an important chemical substance source to the sea [4][5].…”

Knowledge related to land-use management impacts on the Baltic Sea ecosystem is limited. The constant release of pollutants into water bodies has resulted in water quality degradation. Therefore, only the innovative approaches integrated with research will provide accurate solutions and methods for proper environment management and will enable understanding and prediction of the impacts of land-use in the Baltic Sea region. Modelling approaches have become essential to address water issues and to evaluate ecosystem management. There are many water quality models, but only a few work in the operational mode and only some of them can be used as an interactive tool for environmental management to assess the impact of pollution on water quality. This study presents a new approach for investigating the influence of pesticides and nutrient fluxes from agricultural holdings and land-use *

“…All of the species in this geologically young sea are originally either from freshwater or from marine ecosystems, and only a few of the macroscopic species have fully adapted to the brackish environment (Snoeijs‐Leijonmalm and Andrén 2017). This, in turn, means that almost all Baltic species live at the edge of their distribution range and that Baltic ecosystems are sensitive to external inputs (Lehtonen et al 2017; Snoeijs‐Leijonmalm and Andrén 2017). The slow seawater turnover rate of approximately 30 yr means that much of the external input entering the Baltic is retained.…”

“…The slow seawater turnover rate of approximately 30 yr means that much of the external input entering the Baltic is retained. This includes both pollutants (e.g., metals, persistent organic pollutants, radionuclides), which are particularly found in the sediments (Evans 1991; Szefer 2002; Meier et al 2006; Lehtonen et al 2017; Schubert et al 2017), and excess nutrients from agricultural runoff that cause eutrophication (Voss et al 2011; Andersen et al 2017).…”

“…The Baltic Sea is also one the most radioactive marine water bodies in the world (Helsinki Commission 2007), mainly due to fallout from the Chernobyl accident in 1986 (Carlson and Holm 1992; Nielsen et al 1999; Helsinki Commission 2018) but with input from nuclear weapons tests, nuclear power plants (NPPs), waste depositories, and research facilities also contributing (Evans 1991; Szefer 2002; Lehtonen et al 2017; Helsinki Commission 2018). Radioactive effluents from NPPs are one of the few current sources of radionuclides to the Baltic Sea (Helsinki Commission 2018), although amounts are small; the accumulated discharges from NPPs accounted for 0.04 and 0.2%, respectively, of the total 137 Cs and 90 Sr inventory in the Baltic Sea in 2010.…”

The Baltic Sea is one of the most polluted seas in the world with widespread eutrophication and radionuclide contamination. Using key species of the Baltic Sea, the effects of eutrophication on uptake and trophic transfer of the radioactive micronutrients commonly found in nuclear power plant effluents were investigated using aquaria in a controlled environment. The aquaria included the brown macroalgae Fucus vesiculosus and the grazers Idotea balthica and Theodoxus This article is protected by copyright. All rights reserved. Accepted Article fluviatilis. Rapid uptake of 54 Mn, 57 Co and 65 Zn from water was observed in all biota, and eutrophication combined with grazing pressure strongly influenced the uptake in F. vesiculosus. Uptake of 54 Mn, 57 Co and 65 Zn to I. balthica and T. fluviatilis grazing on F. vesiculosus was also observed. The results indicate that ecosystems could be open for further trophic transfer as radionuclides accumulate quickly in the producers and are transferred to primary consumers.

“…Так как оценка качества природных вод Гидрометцентром производится только в пределах Невской губы, информация о состоянии водного объекта западнее дамбы отсутствует. Имеются данные исследований северного побережья Финского залива [3], [4], Невской губы [5], а также данные ряда иностранных журналов, описывающих химическое загрязнение вод Балтийского моря ПХБ (полихлорированные бифенилы) и ДДТ (дихлордифенил трихлорметилметан) [6], загрязнение донных осадков [7], наличие органогалогенных токсикантов в рыбе Финского залива [8], содержание эвтрофикантов в водах Финского залива [9]. Тем не менее эти исследования не показывают содержание химических загрязнителей, таких как железо, медь, нефтепродукты на южном побережье Финского залива.…”

A laboratory study of the natural waters of the Gulf of Finland near the coastal zones of the main large beaches of the southern coast on the content of pollutants was conducted to identify the main pollutants exceeding the maximum permissible concentrations in the waters of the southern coast of the Gulf of Finland, the allocation of sources of these substances and describe the prospects for bringing these indicators to regulatory concentrations. Laboratory tests were carried out at 4 points: the first point was taken in the dam near the village of Martyshkino, the second is taken in the coastal zone of the beach of the village of Bolshaya Izhora, the third in the beach area, the former pier fish factory, the fourth was taken in the coastal zone of the beach of Sosnovy Bor. The results of laboratory research on presence of polluting substances of natural waters of the coastal zone of the Gulf of Finland are given. The results of the study of water quality at these points showed how and what human activity affects the chemical composition of the natural waters of the Gulf of Finland within the boundaries of the southern coast. A comparative analysis of the results of the study of the waters of the Gulf of Finland, given the statistics of exceedances for 2016-2017. Bringing these substances to the standards of maximum permissible concentrations will give the necessary water quality in the Gulf of Finland, suitable for recreational purposes, including swimming and fishing. A description was given of the main sources that contribute these pollutants to the waters of the Gulf of Finland. The article describes the main problems, the solution of which is necessary to bring the quality of the Gulf of Finland to the normative. The article also describes background, natural pollution peculiar to St. Petersburg and the Leningrad region, reduction of which to the standards established by the law is impossible in consequence of the specifics of the composing soils of this area.
