  • Assessment of water and bottom sediment pollution with heavy metals and arsenic in the Caucasus Region of the Black Sea at the present time

    Evseeva, A.I.; Korablina, I.V.; Gevorkyan, Zh.V.; Katalevsky, N.I.; Gorgola, L.G.; Bragina, T.M. (2020)
    The content of nine heavy metals (Fe, Mn, Zn, Cr, Cu, Pb, Cd, Hg, Ni) and arsenic in the water and bottom sediments of the North-Eastern Black Sea at the present time (2018–2019) has been estimated, and the results of this investigation are presented. The analyses of samples, collected during the multi-purpose expeditions of the Azov-Black Sea Branch of the FSBSI “VNIRO” (“AzNIIRKH”) in the spring – early summer and summer – early autumn seasons, are summarized. Altogether, 204 water samples and 60 bottom sediment samples have been collected. Estimation of mass concentrations of heavy metals and arsenic has been conducted according to the methods, developed and adopted by the Azov-Black Sea Branch of the FSBSI “VNIRO” (“AzNIIRKH”). Pollution levels in the habitat of aquatic living resources have been assessed based on the standards for maximum allowable concentrations (MAC) of harmful substances in water bodies of fisheries importance and on the average long-term values. In some areas, subjected to the increased anthropogenic pressure, exceedance in MAC of iron, manganese, zinc, and nickel is recorded. It is shown that, at present, the revealed content of heavy metals and arsenic in the water and bottom sediments of the investigated area of the Caucasus Region of the Black Sea does not pose a threat for the aquatic living resources.
  • Specific features of the change in the statistical characteristics of the horizontal structure of the salinity field of the Azov Sea waters

    Panov, B.N.; Spiridonova, E.O.; Bragina, T.M. (2020)
    The work is based on the data from 49 spring, summer and autumn oceanographic surveys carried out by the Azov-Black Sea Branch of FSBSI “VNIRO” (“AzNIIRKH”) in the Azov Sea from 2001 to 2016. As characteristics of the horizontal structure of the salinity field, the radii of the concentration region of the spatial correlation function of the field in the zonal and meridional directions in the surface and bottom horizons were calculated, as well as their ratio reflecting the prevailing direction of water exchange. The average size of meridional radii was 42 km, and for the zonal one it was equal to 46 km. It is shown that, in the surface layer, the radii are maximum in summer and minimum in spring; in the bottom layer they decrease mainly from spring to autumn. The zonal radius prevails in the surface layer of the sea, whereas the meridional one prevails in the bottom. In the trends of long-term changes in the surface layer, the sizes of the meridional radii have increased. In the bottom layer, the zonal radii were decreasing. The years of predominance of zonal radii in the structure of the salinity field were attended with a decrease in the average salinity of the sea, and the predominance of meridional radii was associated with its increase. An almost complete absence of statistically significant relationships between the characteristics of the field, both in seasonal and in average annual values, was noted.
  • Status of the Chamelea gallina and Pitar rudis communities in the North-Eastern Black Sea in the autumn of 2019

    Frolenko, L.N.; Zhivoglyadova, L.A.; Bragina, T.M. (2020)
    Spatial distribution and quantitative characteristics of the main bottom communities in the North- Eastern Black Sea, characterized by the prevalence of the native bivalve species Chamelea gallina and Pitar rudis, have been considered for the autumn season of 2019. Within the investigated region, at the depth of 18 m,the largest area of sandy biotopes with silt and shell admixture was occupied by a community dominated by the bivalve mollusc Ch. gallina. At the depth of 30 m, a community of the pelophilic bivalve mollusc P. rudis was observed on silty substrate with shells and, at times, sand admixture. In the Chamelea community, molluscs were the most prominent group in terms of abundance and biomass. In the Pitar community, polychaetes were the most abundant in the benthic community, while molluscs prevailed in terms of their biomass. If compared with the data of the 1960s, the contemporary analysis of the materials presented indicates a decrease in the biomass of the macrozoobenthos down to 93 g/m2 and of the dominant species down to 41 g/m2 in the Chamelea community, which is associated with the predominance of small individuals in the mollusc populations. In the autumn of 2019, despite the appearance of invading species, the native species prevailed in the main regional biocoenoses.
  • Dynamics of water quality in the Temernik River considering the toxicity levels based on the data of the biotest battery

    Bakaeva, E.N.; Taradayko, M.N.; Ignatova, N.A.; Zaporozhtseva, A.Yu.; Bragina, T.M. (2020)
    The urbanized section of the Temernik River (Rostov-on-Don, Southern Federal District) is subjected to anthropogenic pressure. During the investigation of water toxicity by means of the bioassay method, an obvious disadvantage of using one biotest was revealed. Recently, a biotests battery has been used. However, assessing toxicity based on only one, most sensitive biotest, is untenable. The toxicity assessment has been carried out according to the scale developed by the authors. The scale considers the results of the assessment of toxicity level according to each biotest, and classifies water quality in concordance with the classes adopted in hydrochemistry. The water quality of the Temernik River has been assessed by means of the bioassay method according to a set of practices, taking into account the toxicity levels for each of the applied biotests. The studies were carried out in 2017–2019. The cultures of Chlorella vulgaris, Raphanus sativus (phytotest), and Daphnia magna were used. The water of the Temernik River showed a wide range of toxicity from “low” toxic (2 “a” class) to “extremely” toxic (5 class). The dynamics of water quality was characterized by the increase in toxicity from 2017 to 2019. The highest degree of water toxicity was recorded at the mouth of the Temernik River, in the Don River downstream from the mouth of the Temernik River, and near the Botanical Garden of the Southern Federal University at the storage site for extracted bottom sediments. Biotest data are confirmed by the analytical data on water pollution.
  • Assessment of caesium-137 accumulation in the bottom sediments and aquatic bioresources of the Azov Sea at the present time

    Mkhitaryan, I.D.; Korablina, I.V.; Bragina, T.M. (2020)
    The results of radioecological investigation of the bottom sediments in the Azov Sea are given for 2017–2019. Pollution of the Azov Sea bottom sediments during the period under study has been detected sporadically and is determined by redistribution of predominately post-Chernobyl fallout. The level of caesuim-137 pollution of the bottom sediments has been evaluated in comparison with its long-term average values. The results of monitoring of radiocaesium content in the main commercial fish species of the Azov Sea are presented for the same period. Comparison of caesium-137 content in the fish muscle tissues according to the sanitary and epidemiological regulations and standards, currently in force in the Russian Federation, is made. It is shown that the content of caesium-137 in the aquatic biological resources of the Azov Sea is much lower than the maximum permissible content of this isotope in fish and does not pose a radiation threat. For the investigated period, the state of the Azov Sea environment in terms of radiation does not give cause for concern pertaining to the accumulation of caesium-137 isotope. Radioecological monitoring of the Azov Sea area in 2017–2019 has revealed that Chernobyl trace remains the main source of radiation pollution.
  • Characterization of the allometric growth of soft-shell clam (Mya arenaria Linnaeus, 1758) in the Southern Azov Sea

    Zolotnitsky, A.P.; Sytnik, N.A.; Bragina, T.M. (2020)
    Allometric growth in the soft-shell clam, or sand gaper (Mya arenaria L.) population, inhabiting the Southern Azov Sea, is investigated. Quantitative characterization of relationship between the height (H, mm), depth (D, mm) and length (L, mm) of the shell of this mollusc, as it is based on the equations of linear (Y=a+b·X) and power (Y=a·Xb) functions, is presented. Shell shape parameters in the process of soft-shell clam growth, namely, elongation (H/L), and sagittal (D/L) and frontal (D/H) curvatures, have been studied. The relationship between mollusc length and its live body weight (W, g) is identified; it is approximated by a power function with the coefficient of proportionality (a) 1.64·10-4 and the coefficient of regression (b) 2.90. By means of the linear function, the new data on the relationship between shell weight (Wr), wet (Wm) and dry (Ws) weight of soft tissues, liquid held in the mollusc mantle (Wmj), siphon weight (Ws) and the total (live body) weight of soft-shell clam have been obtained. It is shown that several morphological characteristics of this species inhabiting the Azov Sea are similar in terms of their parameters to the ones of soft-shell clam populations in the White and Baltic Seas, although there exist certain distinctions.
  • Estimation of the meat yield of veined rapa whelk during its processing

    Esina, L.M.; Gorbenko, L.A.; Bragina, T.M. (2020)
    Technological standardization of the product yield after processing of aquatic bioresources is conducted to facilitate their rational management and the control over their exploitation; it also provides the means to plan out the product output and consumption of raw materials. At present, the standards for wastes, losses and meat yield are absent for the processing of a major fishing target in the Azov and Black Sea Fishery Basin, namely, veined rapa whelk Rapana venosa. In this article, the results of development and control work on standardization of wastes, losses and meat yield for veined rapa whelk, conducted in the processing environment and in the laboratory setting, are presented. The yield of veined rapa whelk meat was assessed as a proportion of the total weight of raw material incoming for processing. It is shown that the meat yield depends on the month when veined rapa whelk was harvested. The highest yield was recorded for May and June; in July and August, a decrease in the yield of veined rapa whelk meat was observed, which resulted from the growth of egg cases on the mollusc shell. For the individuals, on which shells egg cases are absent, or have been removed, a unified standard of meat yield for the entire course of harvesting season should be adopted. The meat yield for the individuals, which shells have not been cleaned of egg cases, is recommended to be regulated separately. A relation between meat yield and shell length has not been found. Statistical analysis of the data obtained on the yield of veined rapa whelk meat has shown their adherence to the law of Gaussian distribution.

  • Водные биоресурсы и среда обитания. Том 3, вып. 3

    Bragina, T.M.; Azov-Black Sea Branch of VNIRO (Azov-Black Sea Branch of the FSBSI “VNIRO” (“AZNIIRKH”)Rostov-on-Don, Russia, 2020)
    Water and bottom sediment pollution with heavy metals and arsenic in the Caucasus Region of the Black Sea has been assessed for the present time. Specific features of the change in the statistical characteristics of the horizontal structure of the salinity field of the Azov Sea waters have been decribed. Dynamics of water quality in the Temernik River considering the toxicity levels have been analyzed based on the data of the biotest battery. Caesium-137 accumulation in the bottom sediments and aquatic bioresources of the Azov Sea has been estimated for the present time. Status of the Chamelea gallina and Pitar rudis communities in the North-Eastern Black Sea in the autumn of 2019 has been identified. Allometric growth of soft-shell clam (Mya arenaria Linnaeus, 1758) in the Southern Azov Sea is characterized. The meat yield of veined rapa whelk during its processing has been estimated. It is also reorted on the Advisory Board Meeting of the Aquatic Sciences and Fisheries Information System held on August 10–14, 2020.
  • Correlation analysis of pelagic fish stocks and biomass of ctenophore Mnemiopsis leidyi A. Agassiz, 1865 in the Azov Sea

    Afanasyev, D.F.; Kulba, S.N.; Shliakhov, V.A.; Belousov, V.N.; Bragina, T.M. (2020)
    Comparison of estimates of pelagic fish stocks (the European anchovy Engraulis encrasicolus (Linnaeus, 1758) and the Black Sea sprat Clupeonella cultriventris (Nordmann, 1840)) and the biomass of ctenophore Mnemiopsis leidyi (A. Agassiz, 1865), based on lampara net and plankton surveys in the Azov Sea in the summer seasons of 1989–2018, has been carried out. An attempt was made to investigate, to what degree Mnemiopsis is able to limit the development of anchovy and sprat in terms of their abundance, as well as whether the stocks of anchovy and sprat play a significant role in the formation of the biomass of Mnemiopsis in the Azov Sea, and in case they do, how significant this role is. To assess the influence of the Mnemiopsis development level on the stocks of the European anchovy and the Black Sea sprat, the data on the maximum summer biomass of ctenophore in the Azov Sea were compared with the stocks of these fish species, estimated based on the lampara surveys conducted in August by the cross-correlation method. To assess the influence of anchovy and sprat on the development of Mnemiopsis, the data on their stocks, collected during the assessment surveys conducted in June, were compared with the maximum biomass of ctenophores in the Azov Sea, recorded in the same years in July–August. Correlation analysis has shown that the biomass of the ctenophore Mnemiopsis negatively correlates with the European anchovy stock with a shift of +2 years. No reliable correlation between the biomass of Mnemiopsis and the Black Sea sprat stock in the Azov Sea has been revealed. The total stocks of pelagic fish species in the Azov Sea at the beginning of summer and the ctenophore biomass that forms in the following months are characterized by a weak negative correlation.
  • Estimation of the parameters of sexual maturity in hydrobionts in the absence of visible maturity indicators in a part of mature individuals

    Mikhaylyuk, A.N.; Piatinskii, M.M.; Bragina, T.M. (2020)
    The problem of estimation of the true value of the length at which 50 % of fish or crustacean individuals are sexually mature is considered for the case when maturity indicators are absent in a part of mature individuals. As a means to solve this problem, it is proposed to use three-parameter models similar to traditionally used twoparameter ones, defined by a logistic function or the normal probability integral. In this case, the third parameter is the estimation of the fraction of mature individuals that present discernible maturity indicators. Based on the data from literature sources, it is shown that, in such cases, the three-parameter logistic model in the add-on package drc for the open-source environment R can be used. As the input data for the estimation, the published data on female individuals of such species of aquatic living organisms as tiger prawn Penaeus semisulcatus (De Haan, 1844) and wide-eyed flounder Bothus podas (Delaroche, 1809) have been used. In some cases, in order to compare the results, the estimation has also been done using the conventional method, involving linear approximation of the logistic function with application of the software package SPSS. It was concluded that, when the parameter defining the upper asymptote deviates from 1 in a statistically significant manner, it is expedient to use the aforementioned three-parameter model. However, when this parameter does not deviate from 1 in such a way, it is advisable to use the two-parameter model, defining this parameter as a fixed value equal to 1.
  • Characterization of the functional state of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1845) in the Azov Sea at the end of the wintering period

    Sergeeva, S.G.; Bugaev, L.A.; Voikina, A.V.; Lezgovka, N.A.; Tsybulskaya, M.A.; Bragina, T.M. (2020)
    The physiological state of a sample of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1845) from the Azov Sea at the end of its wintering period is analyzed. The state of females and males was assessed by the content of total protein, moisture and lipids in the muscles, liver and gonads, by protein content, including albumin and globulins, cholesterol, triglycerides in the blood serum, and by the characteristics of the variation series of oocyte diameters in females. The reduced content of protein and fat in the muscles and liver, fat in the gonads of females, and carotenoids in the liver and gonads is noted in comparison with the long-term data characteristic for the early spring period. The content of protein, cholesterol and triglycerides in blood serum was also reduced. Values of protein coefficient (albumin-to-globulin ratio) did not exceed 0.73, which is not typical for this blood serum parameter (normally above 1.0). The dynamics of the investigated biochemical parameters of blood indicated an insufficiently active transport of nutrients, in particular albumin and triglycerides, to the organs and tissues. The females had gonads of the 3rd maturity stage; diameter of the oocytes reached 0.25–0.35 mm, and larger oocytes have not been recorded in the majority of the investigated fish individuals, which suggests a lower degree of gonadal maturity during this period. Satisfactory physiological state of the so-iuy mullet at the end of its wintering is associated with a significant decrease in temperature in early November 2018, which led to a decrease in the duration of autumn feeding and to an earlier onset of the wintering period.
  • Водные биоресурсы и среда обитания. Том 3, вып. 2

    Bragina, T.M. (Azov-Black Sea Branch of the FSBSI VNIRO (AZNIIRKH)Rostov-on-Don, Russia, 2020)
    The need to develop regional databases for the bioindicators of the water bodies status is considered. Correlation analysis of pelagic fish stocks and biomass of ctenophore Mnemiopsis leidyi A. Agassiz, 1865 in the Azov Sea is made. The parameters of sexual maturity in hydrobionts in the absence of visible maturity indicators in a part of mature individuals are estimated. The functional state of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1845) in the Azov Sea at the end of the wintering period is characterized. The role of accidental introduction of the invader species Northern snakehead (Channa argus Cantor, 1842) in the ichthyofauna composition of the Balkhash-Ili Basin is assessed. Influence of amateur and recreational fishing on the state of the aquatic biological resources in the Tsimlyansk Reservoir is studied.
  • On the need to develop regional databases for the bioindicators of the state of water bodies

    Barinova, S.S.; Bragina, T.M. (2020)
    This review article discusses the problems associated with the implementation of bioindication methods for continental and marine water bodies at a regional scale, and ways to solve them. The possibilities of environmental assessment opening up with the expansion of the application of bioindication methods are described. Methods that enable a broader interpretation of the obtained bioindication data in environmental assessments, such as visualization, are considered. References to works describing updated methods of environmental mapping of data based on environmental indicators, biota, and bioindication results in the area of both lentic and lotic water bodies, including the water catchment area, are given. A table of the available data on the indicators of water properties by algae, cyanobacteria, bryophytes, fern-like and higher aquatic plants, which habitat is confined to continental water bodies, is presented. References to the sources that contain lists of algae indicator organisms for 12 environmental parameters are given, as well as examples of their application in bioindication at water bodies of various types. It is emphasized that it is important that indicators of the second and third trophic levels, especially aquatic invertebrates, which have regional distribution specific features, are included in the regional lists. Statistical software programs that offer the possibility to optimize working with lists of indicators and their quantitative data in communities are presented. It is concluded that there exists the need to create regional databases on indicator taxa of various trophic levels.
  • On the significance and role of accidental introduction of the invader species Northern snakehead (Channa argus Cantor, 1842) in the ichthyofauna composition of the Balkhash-Ili Basin

    Ismukhanov, Kh.K.; Kassymbekov, Ye.B.; Pazylbekov, M.Zh.; Bragina, T.M. (2020)
    An alien species Nothern snakehead (Channa argus Cantor, 1842) from the water bodies of the People's Republic of China and Republic of Korea was accidentally introduced, along with the larvae of herbivorous fish species, into the basins of the Syr Darya River and the Aral Sea in the 1960s; afterwards it spread to numerous water bodies in South Kazakhstan. Subsequently, in 2003, a certain number of the Northern snakehead juveniles was brought into one of the ponds near Almaty, and from there, through the canal network and the Kaskelenka River, it entered the Qapshaghay Reservoir of the Balkhash-Ili Basin. This article discusses the issues of adaptation and the propagation process of the invader in its new living conditions, as well as its biological characteristics and nutrition. Due to the differences in habitat stations and methods of obtaining food, there is a lack of food competition between the new invader and other predatory fish. Following the results of the analysis, the Northern snakehead is found to play a positive role in utilization of the food supply of carnivorous species, which comprises abundant non-commercial fish species of the Chinese complex that compete with juveniles of all commercial fish species in the water bodies for food. Based on the above differences in the habitat and nutrition stations, it is predicted that with the completion of naturalization process, the abundance and fishing stocks of the Northern snakehead will be significantly lower than these of three predatory fish species (zander, asp and catfish) previously acclimatized in the investigated water bodies. The volumes of commercial snakehead catch in the recent years, which range from 4.9 to 5.3 % of the total fish catch, are shown.
  • Employees of the Volgograd Branch of “VNIRO”, who merit eternal memory and respect for their actions in the Great Patriotic War

    Khoruzhaya, V.V.; Kochetkova, A.I.; Kashirina, A.A.; Abashkin, V.M.; Bragina, T.M. (2020)
    This article was prepared in honor of the 75th anniversary of the Victory in the Great Patriotic War. The Volgograd Branch of “VNIRO” is located in the Hero City, well-known by every person on our planet, Volgograd (formerly Stalingrad). It was in the city of Stalingrad when a turning point in the Great Patriotic War, in which the Soviet troops won and seized the strategic initiative over the Wehrmacht, happened on February 2, 1943. Due to the significance of the Battle of Stalingrad in the Great Patriotic War, a comprehensive analysis of the biographical data of the Volgograd Branch employees, who were involved in the military operations, was carried out. It is based on the archive materials of the Volgograd Branch of “VNIRO”, which are presented in the form of personal files of the employees and the results of their research activity (scientific publications, reports, etc.).
  • Influence of amateur and recreational fishing on the state of the aquatic biological resources in the Tsimlyansk Reservoir

    Kutsenko, N.V.; Chukhnin, V.A.; Naumenko, A.N.; Filipenko, A.A.; Bragina, T.M. (2020)
    Amateur fishing with recreational purposes is one of the most popular types of recreation for the population at the inland freshwater bodies of our country, and the development of recreational fishing is one of the important tasks, which fishing industry currently faces. At the same time, uncontrolled fishing or harvesting of aquatic biological resources by amateur fishers can lead to extremely negative consequences for the their exploited stocks and for the ecological state of the water body. This paper presents the results of studies on the impact of amateur and recreational fishing on aquatic biological resources of the Tsimlyansk Reservoir within the boundaries of the Volgograd Region carried out in 2019. Based on visual observations and direct survey, the number of amateur fishermen who visited the Tsimlyansk Reservoir during the entire period of observation has been assessed. According to the estimated data, the amateur fishermen's total catch, as well as the average catch per a fisherman have been determined. The most visited sites where the highest density of amateur fishers was observed have been identified; the main targets of amateur and recreational fishing have been determined, and their main biological characteristics such as size and body weight have been investigated; catch intensity in relation to the species of aquatic biological organisms has been determined by calculation methods; the annual yield of aquatic biological resources by species has been estimated. In total, the analysis of 7774 fish specimens has been performed in the course of the work. In the catches of amateur fishermen, 17 species of fish have been recorded, namely: zander, Volga zander, Northern pike, silver bream, asp, Prussian carp, common bream, European perch, roach, European carp, blue bream (zope), wels catfish, ide, goby, white-eye bream, common rudd, and common bleak. It has been found that 39.6 % of zander, 90.8 % of common bream, 89.5 % of European carp, 57.7 % of wels catfish and 75 % of ide individuals out of the total number of examined specimens of the corresponding species were smaller than the minimum landing size allowed by the Fisheries Regulations for amateur fishing. Based on the analysis of the collected data, an assessment of the extent of the impact that amateur and recreational fishing exerts on the aquatic biological resources in the Tsimlyansk Reservoir has been made. Thus, the catch of amateur fishermen in 2019 in the Tsimlyansk Reservoir within the boundaries of the Volgograd Region is estimated at 104.3 tons, 51.3 tons of which are accounted for by such a valuable commercial species as zander.
  • They expedited the Victory. Science and fisheries of Southern Russia during the Great Patriotic War

    Bragina, T.M.; Azov-Black Sea Branch of VNIRO (2020)
    In May, 2020, the Azov-Black Sea Branch of the FSBSI “VNIRO” (“AzNIIRKH”) published the book of historical materials, dedicated to the 75th anniversary of the Victory in the Great Patriotic War, entitled “They expedited the Victory. Science and fisheries of Southern Russia during the Great Patriotic War”. This book of the collected articles, peer reviewed under the supervision of V.N. Belousov, Candidate of Biology, is prefaced with the addresses of K.V. Kolonchin, Director of the FSBSI “VNIRO”, and E.A. Kozhurin, Head in Charge of the Azov-Black Sea Branch of the FSBSI “VNIRO”. Through their congratulatory and commemorative speeches, they remind researchers and other fisheries personnel of the contribution made by their former fellows into the defense of their native country against Nazi aggressors. The articles from this collection deal with the essential role played by fishers and fishing fleet in the Great Patriotic War. When agriculture failed to cope with the task of providing the USSR population with food, fish proved to be an indispensable source of nutrition. However, research institutes and their scientific and fishing fleets did much more than just supplied people with food. Fishing and research vessels participated in combat, — among other things, they made their input into the Soviet Kerch-Feodosia Landing Operation. Furthermore, AzCherNIRO and the Don-Kuban Fishery Research Station (the institutions, which were the predecessors of the current Azov-Black Sea Branch of the FSBSI “VNIRO”) continued to function in their scientific capacity. While the main section of this book is dedicated to the general situation at the Azov-Kuban, Azov-Don and Crimean Fishery Basins, the chapter “Immortal Regiment” deals with specific names and faces. This chapter recounts the employees of the Don-Kuban Fishery Research Station and AzCherNIRO, who, directly or indirectly, took part in the Great Patriotic War. Readers are presented with their biographical data and the means of their involvement into military operations. The book is concluded with memoirs of AzNIIRKH employees, whose childhood fell upon the grievous wartime years. E.Z. Mazyar, T.D. Didenko, G.S. Kornienko, and L.T. Gorbacheva tell the readers about the most dreadful period of their lives and recall their experience during those years: being uprooted from their homes, Nazi occupation, bombardments, diseases, and famine. Still, the book culminates on a positive note. In the most difficult of times, the best human qualities come into the forefront, and the past experience, no matter how tragic, could be used as an inspiration and a guidance during the peaceful present.
  • Analytical testing center of AzNIIRKH celebrates its 25th Anniversary!

    Pavlenko, L.F.; Barabashin, T.O.; Bragina, T.M. (2020)
    This article describes the history of the creation and development of the Analytical Testing Center, created on the basis of the Azov Sea Research Fisheries Institute. The founder and first Head of the Analytical Testing Center was Anatoliy Dmitrievich Semenov, Doctor of Chemistry, Corresponding Member of the Russian Academy of Sciences. For 25 years of the Center's operation, the Center has been providing extensive technical and methodological support for assessing the quality of the habitat of aquatic biological resources. Since the end of the last century, the Analytical Testing Center has developed, improved and certified more than 100 methods of quantitative chemical analysis for detection of the following chemical elements and compounds in the main components of aquatic ecosystems (water, sediments and hydrobionts): heavy metals and arsenic, chlorine and phosphorus-containing pesticides, chlorophenols, and the major petroleum components—hydrocarbons and resinous substances, polycyclic aromatic hydrocarbons, paraffinic hydrocarbons, congeners of polychlorobiphenyls, including dioxin-like polychlorobiphenyls, phenols, anionic and non-ionic synthetic surfactants. The Center's work to date has been reflected in the published practical guide to the chemical analysis of water, sediments and hydrobionts for the content of priority toxicants. The scope of accreditation of the Analytical Center covers monitoring of the state of aquatic environment, bottom sediments and hydrobionts of the water bodies of the Azov and Black Sea Basin in order to assess the anthropogenic impact on the habitat of aquatic biological resources, including assessments performed upon the request of third-party organizations.
