Scientists of the NArFU study the ecological state of terrestrial ecosystems on the territory of the Solovetsky Archipelago

PhD student of NArFU, employee of the Arctic biomonitoring laboratory, Anna Trofimova at the interregional youth research conference "Geoecological problems of the European North and the Arctic" told about the accumulation of nutrients in the soils around the filling station of the Solovetsky village.

Despite of the absence of asphalt roads on the Bolshoy Solovetsky Island and, in general, absence of any organized transport communications, there are many cars there. Therefore, the study of the filling station territory, according to researchers, is a key point research which reflects the current ecological situation. Students, undergraduates and postgraduates of the NArFU conducted an analysis of soil samples collected during the summer school of the NArFU-HSE, dedicated to the complex development of the territory with a unique natural and historical and cultural heritage. The project is carried out for several years, for today the soils selected in 2016 have already been fully investigated.

In 2017, the group took samples near the Sukhoi Dock and near the diesel station. In these samples the content of heavy metals, petroleum products and nutrients were determined. Samples were taken around the territory of the gas station in order to identify the biogeochemical indicators of the terrestrial ecosystems ecological status and human loads on them.

"Soils on the territory of the diesel station and Sukhoi dock have a high level of contamination with oil products and heavy metals. After the study, it became clear that these territories require reclamation. In the Sukhoi dock, for instance, which is located near the Solovetsky Monastery, high content of both - oil products and heavy metals, and at the top is a potato field is located. Dangerous contaminants can be accumulated in potatoes and through the food chain can be passed on to people. Based on the results of our research, we want to construct a map of the territory where the places that are experiencing great anthropogenic load will be indicated, " explained Anna Trofimova.

The technogenic load existing in the conditions of the filling station disrupts the biological cycle of substances, changing the features of the arrival and distribution in the soils of chemical elements, the researchers concluded.

In addition, the archipelago is under the anthropogenic pressure from residents and tourists. Over the past decade, the tourist flow on Solovki has increased. For example, in 2015 Solovki was visited by 32 thousand people. At the same time, the archipelago does not formulate a clear environmental policy, there is no water treatment system, unauthorized landfills are formed. After primary soil assesment in the Solovetsky settlement a significant human influence on soils was found.
