Introduction
Research interests: environmental issues of continental water bodies, estuaries, inland seas, seacoasts and coastal zones, assessment of their vulnerability and self-cleaning capacity in case of oil pollution. Due to a series of long-term (up to 15 years) field observations the rates of oil pollution natural destruction were determined and their dependence on the principal geographical factors was quantified in order to assess the self-cleaning capacity of coastal and aquatic ecosystems.

The changes in land use and land cover (LULC) are among the primary drivers of global environmental changes in many developing countries. In this study, LULC changes were assessed on Phu Quoc Island, located in Kien Giang province, Vietnam, from 2001 to 2022. The study utilized remote sensing and Geographic Information System (GIS) technology using...

The present paper considers the results of long-term (up to 17 years) in situ and laboratory research carried out on oiled French, Spanish, and Russian seacoasts. The objective of this research is to quantify the influence of geographical factors on the rates of natural transformation of the heavy fuel oil stranded ashore and to develop an empirica...
In recent decades, numerous oil spills have occurred worldwide and affected coastal environments. In the present paper, we analysed the results of long-term (up to 18 years) field and laboratory studies of temporal changes in the quantity and composition of oil slicks and tar balls in different geographical environments polluted by spilled fuel oil...
In the last few decades, the enormous scale of crude oil extraction, transportation and processing has caused widespread pollution of soils with crude oil and oil products. Thus, its permanent presence in the environment, and, as a consequence, in soils, is due to natural and anthropogenic origin. The authors have conducted expeditionary research i...
The paper examines the results of twelve-year (2007 to 2019) observations of spatial distribution and temporal changes in the concentrations of petroleum components in the coastal waters and sediment cores, as well as in the quantity and composition of oil slicks and tar balls on the beaches, cliffs and solid constructions of the Black Sea coast in...
The chapter considers the results of 12 years (2007–2019) of field observations examining spatial distribution and temporal changes in the quantity and composition of oil pollution traces on the beaches, cliffs, coastal waters, and sediment cores in the Black Sea coastal zone near the city of Novorossiysk and in the Kerch Strait, Russia. Novorossiy...
The paper examines the results of ten-year (2007 to 2016) field observations of spatial distribution and temporal changes in the quantity and composition of oil pollution traces on the beaches and cliffs, in coastal waters and sediment cores carried out on the Black Sea coast in the area of the city of Novorossiysk, which is the most important oil...
Seacoasts are especially exposed to harmful influence of oil pollution as they frequently suffer from oil spills relating to tanker accidents, port and off-shore activities. In the present chapter, the results of original long-term field research carried out on geographically different seacoasts are analyzed in order to determine the rates of spill...
The study of pollutants vertical distribution in seabed sediments is of high interest as they conserve the information on the chronology of pollution level in the past. In the present paper, the results of layer by layer study of Cs-137, Am-241, Pb-210 specific activities as well as concentrations of petroleum components, lead and mercury in 48 sed...

The sea coasts are especially exposed to the oil pollution harmful influence as they frequently suffer from oil spills relating to the tanker accidents, port and off-shore activities. The objective of the present research is to examine the rates of spilled fuel oil natural destruction on geographically different seacoasts and to evaluate their rela...
Bottom sediments formed in the water bodies under the technogenic impact are important environmental factors affecting water quality and hydrobiota. Usually they consist of natural and technogenic material and differ from natural formations by their morphology, chemical and lithological composition, physicochemical and biochemical properties. In th...

The paper is devoted to the comparative analysis of results of long-term field observations carried out on geographically different sea coasts contaminated by spilled fuel oil. Such investigations are of particular interest as they make it possible to assess the rates of oil pollution natural transformation as well as their correlation with princip...
The data given are the results of many-year studying the distribution of the concentrations of main oil components (hydrocarbons, surfactants, and asphaltene-tarry substances) in the water mass, vertically settling particulate matter, and bottom sediment cores taken from the section Lower Don-The Gulf of Taganrog-Russian sector of the Sea of Azov i...
A series of complex scientific expeditions were carried out. The samples of water and bottom sediments of the Big Tambukan Lake were taken. In these samples the specific activities of natural and anthropogenic radio-isotopes including Cesiun-137 and Lead- 210 were measured. Due to the results of analysis of cesiun-137 and lead-210 vertical distribu...
Fattal P., Rollo N., Kuznetsov A.N., Fedorov Yu.A. Cartography of accidental oil pollution risks: different approaches to risk indicators.
The cartography of the accidental pollution risks raises questions of its scale, limits and semantics of indicators chosen to carry out the exercise. In the present paper the geographers from the University of N...
The accidental oil spill that occurred in the Strait of Kertch in November 2007 has affected the coasts of the strait as well as the adjacent sectors of the Sea of Azov and the Black Sea. The observation of this pollution and its natural degradation in the environment shows that the processes are rather dynamic while the spilled fuel is relatively...

The present work is devoted to the analysis of results of investigations carried out in the Russian sector of the Sea of Azov and in the lower part of the Don River during the period from 2006 to 2010. In several scientific expeditions for the first time in the Sea of Azov investigation history 48 sediment cores from 20 to 100 cm thick were taken a...
The principal regularities were ascertained for the spatiotemporal distribution of organic carbon in the water and bottom
sediments of the Russian part of the Sea of Azov. The relationships between allo- and autochthonous organic matter in water
and bottom sediments from different parts of the sea aquatic area were found. The behavior of organic ca...
The sedimentation rate is an important factor influencing the quantitative distribution and composition of sedimentary material, the thickness of bottom sediments, and the dynamics of their transformation at the early diagenesis stage [1]. In [2‐4], the average sedimentation rates were largely determined for the entire Sea of Azov using calculation...
