Opis:: Heavy metals are some of the environmental pollutants that have a serious impact on the environment. The analysis of hydromacrophytes growing in small rivers of the south of Kazakhstan with different contents of heavy metal salts revealed that the morphometric indicators of the same plant species differ significantly, depending on the level of total mineralization of the aquatic environment in different rivers of the Turkestan region. It has been established that two plant species can be used to bioindicate the content of lead ions in the aquatic environment: Azolla caroliniana Willd. and Veronica beccabunga L., which must be introduced into the tested aqueous solutions in the amount of 1.0 kg/m3 and 1.5–2.0 kg/m3, respectively, to fully cover the water column at different depths. The first morphological changes in plants, in the form of destruction of the structure of chloroplasts along the edges of unfolded leaves in A. caroliniana Willd. and slight withering of the lower underwater leaves in V. beccabunga L., occur already at a 1.5 mg/l Pb2+ content in water, and a further increase in the content of lead ions in water to 600.0–800.0 mg/l leads to the death of plants.

Opis:: Testate amoebae (TA) are unicellular protozoans enclosed in a test capable of indicating a wide variety of environmental conditions. Among others, characteristics such as short life cycle, great sensitivity and worldwide distribution makes them adequate bioindicators. As a complement to physical and chemical measurements, biomonitoring can be a cheaper and fastest way of environmental monitoring. This research sought to evaluate the extent of TA use in biomonitoring and the responses given by them to environmental features. The research was conducted in Scielo, Science Direct, Online Library, Google Scholar and Capes Journal Portal and yielded 211 papers. TA bioindication is able to provide information on metal, trace element and atmospheric pollution, and to point out different trophic states, pH, and evidence on characteristics of hydrology. Further, TA can be used in paleoenvironmental reconstruction as they reflect climate, volcanic and even sea level change phenomena. Sometimes, together with other organisms in environmental analysis, they have shown to be an important complement to biomonitoring. Additionally, a functional traits approach has been recently included as a promising tool. Methodological adjustments that have been conducted throughout the years are allowing TA use to be more reliable and precise. This review provides insight on the many possible functions of TA in bioindication studies, highlighting their wide use as bioindicators.

Opis:: The article demonstrates the results of the research studies related to the air polluted with heavy metals in the area of Swietokrzyski National Park. The two-year-old needles of Abies alba (Mill) were used as the bioindicator with the intention of carrying out the research. The studies were conducted in the autumn of 2012. The results showed the spatial variability of concentrations in the range of the analysed metal deposition patterns in the needles of Abies alba (Mill). The average content of the analysed elements seemed to be the highest in the case of zinc (26.6 mg·kg–1 d.m.), strontium (6.5 mg·kg–1 d.m.) and nickel (1.6 mg·kg–1 d.m.). The research studies revealed that the significant role in determining the content of heavy metals in the two-year-old needles was played by the communication. The highest values were recorded at the research sites situated in the immediate neighbourhood of the voivodeship roads. It was also confirmed that the content of metals was influenced by the so-called low emission from the household and welfare sector together with the remote imission.

Opis:: The paper presents the results of research on the implementation of monitoring of the landfills influence on the atmospheric air using bioindication methods on the example of the Zhytomyr landfill (Ukraine)–one of the typical Ukrainian landfills, which is operated with minimal environmental protection measures. A comprehensive study of atmospheric air pollution in the landfill area was carried out using a human sensor system and an integral assessment using bioindication (lichens were chosen as bioindicators). The study revealed a reliable exponential dependence for modeling the relationship between the distance from the source of gas formation (solid waste landfill in the city of Zhytomyr) and the intensity of odor. The level of atmospheric air pollution was also determined based on the assessment of the projective coverage of the tree trunk with lichens. The research revealed an exponential dependence for modeling the relationship between the distance from the landfill boundary and the total coverage of the tree trunk with lichens. The results of the analysis confirmed the correctness of the use of the aforementioned method. The relationship between the results obtained by the lichen indication method and the strength of the odor from the landfill was evaluated. Based on the results of calculating the relative values of the assessment of atmospheric air pollution by the method of coverage of the tree trunk with lichens and the strength of the odor, a regression analysis was carried out and mathematical relationships were determined, that most accurately describe the change in these indicators with distance from the landfill boundary. It is proved that both tested methods can be used in Ukrainian realities to monitor the state of atmospheric air in the area of influence of municipal landfills, depending on the purpose of research. The analysis of the research results confirmed the significance of the results of the obtained assessment of the impact of the Zhytomyr solid waste landfill on the state of atmospheric air. The materials of these studies can find further application for the formation of databases of knowledge of landfills, which will allow to develop a strategy for managing them as an object of increased environmental hazard.

Opis:: Thermal power plants (TPP) belong to the enterprises that accompany the development of any city. These industrial facilities consume and discharge large amounts of water. Therefore, thermal power plants are often located near water bodies that need to assess their ecological state and predict the consequences of the anthropogenic impact. The purpose of the work was to assess the ecological state of the floodplain Lake Ivanovskoye (Russia, Kirov region), which receives the wastewater from a thermal power plant, using a triadic approach and comparing the results of chemical analysis, bioassay and bioindication. It was shown that the main pollutant in the lake and the canal connecting Lake Ivanovskoye with the nearest river Vyatka is ammonium ion (up to 3.2 mg/dm3). In addition, the Russian standards for biological oxygen consumption are exceeded (analysis period is 20 days). The tests for the toxicity of wastewater showed inhibition of Paramecium caudatum and Escherichia coli reactions. In contrast, natural surface water from Lake Ivanovskoye stimulated the test functions of Scenedesmus quadricauda, P. caudatum, and E. coli. The death of Daphnia magna in the samples were not recorded. The totality of the facts pointed to the organic nature of pollution, leading to the anthropogenic eutrophication of the lake. The hypothesis was tested by using the bioindication method and by analyzing the totality of species of coastal aquatic plants. It was shown that the reservoir belongs to the mesotrophic type with a moderate degree of pollution, which decreases with distance from the wastewater discharge points. The increase in the trophicity of the reservoir is facilitated by thermal pollution (up to +15℃) and an alkaline pH of wastewater (up to 9.2). Thus, the joint analysis of the results of chemical analysis, bioassay and bioindication made it possible to carry out an objective assessment of the ecological state of the reservoir and identify the reasons for the revealed facts.

Opis:: One of the widespread sources of river pollution is the wastewater coming from both wastewater treatment plants and the stormwater system. Wastewater can vary significantly in composition and concentration of substances introduced into water bodies. Municipal effluents may contain significant amounts of organic matter and ammonia. Storm drains are diverse in composition and depend on the nature of the surface from which the water collects, but carry more suspended solids and less nutrients. The research was aimed at assessing the effect of surface runoff collected by the stormwater system from the territory of the city of Lublin on the Bystrica River using popular environmental indices, calculated on the basis of periphytonic algae species abundances: species number, Shannon’s H, rarefied species number, Pielou’s evenness, trophic diatom index (TDI). It was observed that the correspondence between a species diversity and the quality of the environment is not always straightforward. Therefore, the periphytonic algae diversity increases under the influence of runoff, as evidenced by the Shannon index. Nevertheless, pronounced changes are noted in the structure of the algal community, as shown by the Pielou index and NMDS. However, these changes in the structure are invisible if the trophic diatom index (TDI) is relied upon.

Opis:: There is a cascade of hydroelectric power plants built on the Váh River. From a water-management point of view, the natural channel is used to drain extreme discharges. During most of the year, discharges are regulated by water-management structures. These discharges are not used for energy-related purposes; therefore, it is important to determine the optimal discharge that will not negatively affect the ecosystem of the stream. The minimum balance discharge (hydro-ecological discharge) was determined based on the instream flow incremental methodology (IFIM) using the riverine habitat simulation system (RHABSIM). Input data were obtained from direct measurements on three reference reaches in the area between the cities Piešťany and Nové Mesto nad Váhom. Hydraulic flow characteristics were derived from three measurements at different water levels. Habitat quality was represented by ichthyofauna. Data to determine the habitat suit-ability curves of fish were obtained using a diving technique to collect video footage. The modelling resulted in the quantification of the effect of discharge on ichthyofauna as a bio-indicator of habitat quality, which implied the need of 20 m³∙s^–1 for a minimum balance discharge in summer.

Opis:: The article reveals the outcomes of the research studies related to air polluted with heavy metals in Swietokrzyski National Park. The thalli of Hypogymnia physodes L. were used as the bioindicator in order to conduct the research. The samples of monk’s-hood lichen were transplanted from the unpolluted area of north-eastern Poland to the area of Swietokrzyski National Park. The research studies were carried out in the warmer half of 2019. The received outcomes indicated the spatial variability of concentrations in the range of analysed metal deposition patterns in the lichen thalli. The average content of the analysed elements tended to be the highest in the case of iron (1,111 mg × kg–1 d.m.), zinc (87.7 mg × kg–1 d.m.) and strontium (27.7 mg × kg–1 d.m.). The research revealed that the important role in determining the content of heavy metals in the lichen thalli was played by the communication. The highest values were recorded at the sites located in the immediate neighbourhood of the voivodeship roads. It was verified that the content of metals was also influenced by the so-called low emission from the household and welfare sector as well as remote immission.

Opis:: The results presented here concern the study, which was carried out in the spring of 2009 on an arable field and a fallow. Following parameters were analysed: density, taxonomic composition, trophic and dominance structure of soil nematode communities. Shannon-Weaver diversity index, Sørensen’s index of similarity and Maturity index were also calculated. The results show that the nematode community in the soil of arable field differed from that on the fallow in respect of density and trophic structure. Nematode density was higher in the arable soil than in the fallow. The group of bacterial-feeding nematodes was the most numerous among five trophic groups recorded in the study. The higher density of that group in the arable soil than in the fallow indicates the positive response of bacterial-feeding nematodes to the higher nutrient supply after the manure applying. The results show that in three years of fallow nematode communities became more mature and diverse than in the arable soil. The study confirms the indicative value of some nematode community parameters and indices for the assessment of the varying human intervention on the functional state of the soil.
Przedstawione wyniki dotyczą badań przeprowadzonych wiosną 2009 roku na polu uprawnym i ugorze. Przeanalizowano parametry zespołów nicieni glebowych, takie jak zagęszczenie, skład taksonomiczny, struktura troficzną i struktura dominacji. Obliczono również wskaźniki różnorodności Shannona-Weavera, podobieństwa Sørensena oraz dojrzałości zespołów. Uzyskane wyniki wykazały, że zespoły nicieni w glebie pola uprawnego różniły się od tych na ugorze pod względem zagęszczenia i struktury troficznej. Zagęszczenie nicieni było większe w glebie uprawnej niż na ugorze. Wśród pięciu grup troficznych stwierdzonych w badaniach najliczniejsza była grupa nicieni bakteriożernych. Większe zagęszczenie tej grupy w glebie ornej niż na ugorze świadczy o pozytywnej reakcji nicieni bakteriożernych na zwiększone zasoby pokarmowe po zastosowaniu obornika. Wykazano również, że zespoły nicieni na odłogu, po trzech latach ugorowania, były bardziej dojrzałe i róznorodne niż na polu. Uzyskane wyniki potwierdziły, że wybrane parametry i wskaźniki zespołów nicieni glebowych można z powodzeniem wykorzystywać do oceny stanu środowiska glebowego na terenach przekształconych w wyniku działalności człowieka.

Opis:: The surface water quality assessment could be based on a combined physical and chemical analysis, but it could also be determined with bioindication methods. Classical physicochemical analysis is in most cases more expensive and time-consuming than the bioindication methods. This type of analysis also requires expensive equipment and shows the situation in the water only at the moment of sampling. Although the bioindication methods are often complicated, they allow a relatively inexpensive estimation of the water quality. Moreover, during their implementation, the substances harmful to the environment are not generated, and the obtained results usually reflect the total interaction of all factors and substances to the analyzed living organisms. Indicator organisms or their communities applied to the research, with identified ranges of tolerance to selected factors, could help to determine the physical and chemical parameters of water. This paper presents a bioindication study with an effect of stormwater system on the receiver – the Bystrzyca river, in Lublin, Poland. The level of saprophyty of the river sector was calculated based on the selected species of algae (diatoms and green algae) and the influence of the stormwater discharge on the communities of these organisms was determined.

Opis:: W celu określenia potencjału toksykologicznego, a tym samym prognozowania skutków jakie może wywołać depozycja nieoczyszczonych lub też niedostatecznie oczyszczonych ścieków szpitalnych względem biocenoz zasiedlających akweny wodne stanowiące odbiorniki ścieków po procesie oczyszczania, przeprowadzono analizę ekotoksykologiczną. Badania przeprowadzono na rzeczywistych próbkach ścieków szpitalnych. Zakres analizy ekotoksykologicznej obejmował przeprowadzenie następujących testów: testy immobilizacji skorupiaków Daphnia magna, test przeżywalności skorupiaków z gatunku Thamnocephalus platyourus oraz Artemia salina, a także test inhibicji wzrostu kolonii orzęsków Tetrahymena termophila. W ramach każdego testu, w oparciu o wyniki cząstkowe wyznaczono wartości wskaźników ekotoksykologicznych EC ₅₀ (ang. effect concentration), które następnie przekształcono na jednostki toksyczności TU (ang. Toxic Unit) na podstawie których dokonano klasyfikacji toksyczności analizowanych próbek ścieków. W ramach przeprowadzonych badań, próbki ścieków szpitalnych sklasyfikowane zostały jako medium charakteryzującego się ostrą toksycznością. Z przeprowadzonych badań wynika, że ścieki szpitalne stanowią poważne zagrożenie względem organizmów zasiedlających ekosystemy wodne, a ich niedostateczne oczyszczenie lub też niekontrolowany zrzut do środowiska może wywołać katastrofalne skutki względem organizmów zasiedlających narażoną biocenozę.
In order to assess the toxicological potential and thus forecast the potential effect posed by untreated hospital wastewater discharges according to exposed ecosystem, the ecotoxicological analysis were performed. During the study the real samples of hospital wastewater were used. The ecotoxicological analysis included the following tests: immobilization test according to crustacean Daphnia magna; mortality test according to crustacean Thamnocephalus platyourus and Artemia salina and growth inhibition test relative to ciliates Tetrahymena termophila. Within each test, the value of ecotoxicological indicators EC50 (effect concentration) were estimated. The EC₅₀ value were transformed into the Toxic Unit (TU), basis of which the analyzed hospital wastewater samples were classified. The results proves that hospital wastewater pose a serious threat to exposed aquatic organisms and their insufficient purification as well as uncontrolled discharge into the environment may cause adverse changes in the environment.

Relatively small but significant increase in the number and diversity of Oribatida species was observed in O variant for the deciduous trees. Mulching was the soil revitalization method that clearly improved the density and biodiversity of Oribatida species. In total, the investigated area harbored 37 species of oribatid mites. The most effective bioindicator and stimulant of soil revitalization was a common fungivorous species Tectocepheus velatus.
Badania były prowadzone w latach 2008-2010 w należącej do Nadleśnictwa Bydgoszcz, szkółce leśnej Białe Błota produkującej sosnę, buk oraz lipę. Badania prowadzone były w następujących wariantach: C – kontrola, O – nawożenie organiczne, M – mulczowanie świeżym humusem, OM – nawożenie organiczne i mulczowanie świeżym humusem. Stosunkowo mały, ale znaczący wzrost liczby i zróżnicowania gatunkowego mechowców zaobserwowano w wariancie O dla drzew liściastych. Mulczowanie było metodą rewitalizacji gleb, która wyraźnie wpłynęła na intensywność i zróżnicowanie gatunkowe mechowców. Na badanej powierzchni stwierdzono ogółem 37 gatunków mechowców. Najskuteczniejszym bioindykatorem i stymulatorem rewitalizacji gleby był powszechnie występujący gatunek grzybożerny Tectocepheus velatus.
