“…According to the total pollution index I geo , there are six pollution levels: uncontaminated (I geo ≤ 0), uncontaminated to moderately contaminated (0 < I geo ≤ 1), moderately contaminated (1 < I geo ≤ 2), moderately to heavily contaminated (2 < I geo ≤ 3), heavily contaminated (3 < I geo ≤ 4), heavily to extremely contaminated (4 < I geo ≤ 5), and extremely contaminated (I geo > 5). For both indexes, the concentrations of studied elements in the preindustrial layers of sediments of small lakes in the Republic of Karelia, Russia, were used as the background level [17][18][19].…”

“…The water pollution level in the lakes of Murmansk, as determined based on a combination of indicators, is also reflected in the condition of the sediments of these water bodies. The total content of almost all heavy metals in the sediments of the lakes of Murmansk exceeds the background level, which is interpreted as the content of the same elements in the preindustrial layers of the sediments of small lakes in the Republic of Karelia, Russia [17][18][19], located to the south of the Murmansk region (Figure 4). Only the background level of Mn is higher or at the same level as in the investigated urban lakes, which may be due to the natural accumulation of this metal in sediments.…”

This paper presents the first study of five small lakes located in the city of Murmansk. Field work was carried out during 2018-2019. Water samples were collected using a bathometer, while the sediments were sampled using an Ekman grab and Limnos gravity corer. It was found that the water of the studied lakes in Murmansk belong to the sodium group of the chloride class and to the calcium group of the hydrocarbonate class. Compared to the background level, elevated pH, concentrations of the main cations of alkali and alkaline-earth metals, N compounds, total dissolved solids, and heavy metals were found in the lakes, which indicate exposure to anthropogenic impacts. The sediments of the lakes, composed of organomineral and mineral silts, also have an elevated content of heavy metals compared to the background. The most significant excessive concentrations were found for V, Ni, Sb, Pb, Co, Cr, and W. Based on the calculated pollution load index and geoaccumulation index of the sediments, the studied water bodies in Murmansk can be classified as lakes with heavy and extremely heavy pollution levels. The primary pollution sources are emissions from the Murmansk thermal power plant, coal port, road and, rail transport.

“…There, the anthropogenic pollution of the aquatic environment is mainly related to urban areas and rarely to industrial areas [53]. The majority of paleolimnological studies of the anthropogenic impact on lakes were conducted in Petrozavodsk, the largest city of Karelia [54,55]. For instance, the detailed analysis of the sediment core of Lake Lamba located in the northern part of the city district revealed a tendency towards increased concentrations of heavy metals, including Pb (up to 137 mg/kg, while background is 4 mg/kg), Cd (up to 1.2 mg/kg, background is 0.2 mg/kg), Ni (up to 607 mg/kg, background is 22 mg/kg), V (up to 4785 mg/kg, background is 17 mg/kg), Cr (up to 179 mg/kg, background is 10 mg/kg), Cu (up to 1189 mg/kg, background is 45 mg/kg), Zn (up to 963 mg/kg, background is 136 mg/kg), etc.…”

Lake sediments are a reliable source of information about the past, including data of the origin of water bodies and their changes. Russia has more than 2 million lakes, so paleolimnological studies are relevant here. This review deals with the most significant studies of sequential accumulation of pollutants, including heavy metals in recent lake sediments in Russia. The key areas are northwestern regions of Russia (Murmansk Region, the Republic of Karelia, Arkhangelsk Region), the Urals (Chelyabinsk Region, the Republic of Bashkortostan), and Siberia. The review presents the data of pollutants accumulation, the sedimentation rate in lakes in the anthropogenic period, and the key sources of pollution of the environment in each of the mentioned regions. The article is divided into three parts (sections): industrial areas, urbanized areas, and background (pristine) areas so that readers might better understand the specifics of particular pollution and its impact on lake ecosystems. The impact of metallurgical plants, mining companies, boiler rooms, coal and mazut thermal power plants, transport, and other anthropogenic sources influencing geochemical characteristics of lakes located nearby or at a distance to these sources of pollution are considered. For instance, the direct influence of factories and transport was noted in the study of lake sediments in industrial regions and cities. In the background territories, the influence of long-range transport of pollutants was mainly noted. It was found that sedimentation rates are significantly lower in pristine areas, especially in the Frigid zone, compared to urbanized areas and industrial territories. In addition, the excess concentrations of heavy metals over the background are higher in the sediments of lakes that are directly affected by the source of pollution. At the end of the article, further prospects of the development of paleolimnological studies in Russia are discussed in the context of the continuing anthropogenic impact on the environment.
