Additionally, the Goodnight and Whitley index is used: J = (number of oligochaetes / number of all invertebrate zoobenthos) x 100%. At J = 60% - the state of the river is good, 60-80% - doubtful, more than 80% - severe. For small rivers with fast current and diverse fauna use the Parele index : D1 = Tubifex abundance/abundance of all zoobenthic invertebrates. With D1= 0.01-0.16 - very pure water; 0.17-0.33 - pure; 0.34-0.50 - slightly contaminated; 0.51-0.67 - contaminated; 0.68-0.84 - dirty; 0.85-1.0 - very dirty. In rivers and reservoirs with an unfavorable oxygen regime and poor benthos, represented mainly by oligochaetes, a different Parele index is used: D2 = Tubifex numbers/all oligochaetes. At D2 = 0.30 - pure water; 0.30-0.54 - slightly polluted; 0.55-0.79 - contaminated; 0.8-1.0 - heavily polluted. Mass development of oligochaetes without more exact definition considered as an indicator of pollution (Berezina, 1989). If the number of oligochaetes is 100-999 ind. per sq. m, pollution is weak, with 1000-5000 ind. per sq. m - average, with more than 5000 copies. - strong. |

Introduction
Biomonitoring is an integral part of environmental monitoring monitoring the state of the environment in terms of physical, chemical and biological indicators. The tasks of biomonitoring include a regular assessment of the quality of the environment using living objects specially selected for this purpose. In 1990, the Economic Commission of Europe under the auspices of the UN adopted a program of integrated monitoring (IM) of the environment for the following groups of indicators (their number is indicated in brackets): general meteorology (6), air chemistry (3), soil and groundwater chemistry (4 ), chemistry surface water(4), soil (6), biological indicators (11).
Biological monitoring is the tracking of natural and anthropogenic processes occurring in biocenoses and at higher levels of biological organization in order to identify changes that occur when living things interact with environmental factors (population fluctuations, accumulation of heavy metals in organisms, etc.) and studying the responses of all biological levels to these impacts (climate change, destruction of biocenoses, diseases of organisms, etc.).
Bioindication is one of the methods of biological monitoring. Bioindication is the detection and determination of environmentally significant natural and anthropogenic loads based on the reactions of living organisms to them directly in their habitat. Living objects (or systems) are cells, organisms, populations, communities. They can be used to evaluate abiotic factors(temperature, humidity, acidity, salinity, content of pollutants, etc.) and biotic (well-being of organisms, their populations and communities).
There is another method of biological monitoring. Biotesting (bioassay) is a procedure for establishing the toxicity of an environment using test objects that signal danger, regardless of which substances and in what combination cause changes in vital functions in test objects. To assess the parameters of the environment, standardized reactions of living organisms (or individual organs, tissues, cells and molecules) are used.
To conduct various studies in the field of biomonitoring, bioindicators are required, with the help of which indicators of the quality of water bodies, the atmosphere, and the state of soils are determined. The main bioindicators will be discussed in more detail below.
1. Biological monitoring methods
1. Bioindication - a method that allows you to judge the state of the environment by the fact of the meeting, absence, developmental features of bioindicator organisms. Bioindicators - organisms, the presence, quantity or developmental features of which serve as indicators of natural processes, conditions or anthropogenic changes in the habitat. Conditions determined using bioindicators are called bioindication objects.
2. Biotesting - a method that allows in the laboratory to assess the quality of environmental objects with the help of living organisms.
3. Assessment of biodiversity components - is a set of methods for comparative analysis of biodiversity components.
1.1 Bioindication method
Objective facts testify to the existence of a close influence of environmental factors on the biotic processes of the ecosystem (population density, dynamics of species structure, behavioral characteristics). Environmental factors such as light, temperature, water regime, biogenic elements (macro- and microelements), salinity, and others are of functional importance for organisms at all major stages of the life cycle. However, it is possible to use the inverse pattern and judge, for example, by the species composition of organisms about the type of physical environment. Therefore, “bioindication” is the determination of biologically significant loads based on the reactions of living organisms and their communities to them. This fully applies to all types of anthropogenic pollution.”
Significant methodological difficulties of bioindication also arise when assessing the state of the biocenosis by the ratio of species in a particular ecosystem by a selective method. If we proceed from the understanding of the population as a collection of individuals, then the information that we received cannot be extrapolated beyond the time period or station (polygon) at which the sample was made. It is necessary to obtain information about the form of the distribution of the probabilities of finding individuals at a particular point in the ecosystem space. Based on the found distribution law, it is possible to calculate the number of required samples that provide a given interpolation accuracy. Such an approach is possible to assess the state of populations in small areas, for example, in small closed shallow water bodies. For large water bodies, the number of samples is limited by the time during which samples can be taken under similar conditions (for example, even within a day, redistribution of plankton individuals in space can occur). The problems associated with the study of spatio-temporal differentiation of zooplankton during monitoring studies are shown, for example, on the large experimental material of O.M. Kozhova and B.K. Pavlov.
Thus, bioindication can be defined as a set of methods and criteria designed to search for informative components of ecosystems that could:
- adequately reflect the level of environmental impact, including the complex nature of pollution, taking into account synergistic phenomena operating factors;
- diagnose early disturbances in the most sensitive components of biotic communities and assess their significance for the entire ecosystem in the near and distant future.
From the point of view of mathematics, the task of bioindication under real conditions belongs to the class of poorly formalized tasks, since it is characterized by the following features:
- significant multidimensionality of environmental factors and measured parameters of ecosystems;
- strong interdependence of the whole complex of measured variables, which does not allow to single out in pure form the functional relationship of two individual indicators F(x);
- the non-stationarity of most of the information about objects and the environment;
- the complexity of carrying out the entire complex of measurements in the same coordinates of space and time, as a result of which the processed data have extensive gaps.
1.2 Bioassay method
Biotesting is the use of biological objects (test objects) under controlled conditions to identify and evaluate the effect of environmental factors (including toxic ones) on an organism, its individual function or system of organisms.
The most complete methods of biotesting have been developed for hydrobionts and can be used to assess the toxicity of natural water pollution, control wastewater toxicity, express analysis for sanitary and hygienic purposes, to conduct chemical analyzes for laboratory purposes and a number of other tasks.
Depending on the goals and objectives of toxicological biotesting, various organisms are used as test objects: higher and lower plants, bacteria, algae, aquatic and terrestrial invertebrates, and others.
1.3 Method for assessing the significance of impacts
The significance of the impact directly depends on its type or nature (noise, radiation, emissions of certain substances into the air, etc.), physical magnitude and probability of its occurrence [Cherp et al., 2000]. The concept of magnitude here encompasses several factors, such as the intensity of the impact (for example, an increase in the BOD5 value in a river to 10 mg/l); duration of exposure; the extent of the impact. At the same time, the scale of spread of the impact is assessed both in terms of the area (for example, the territory on which an increase in the radiation level was recorded), and in terms of the number of biological objects, the presence of specially protected areas, etc., exposed to this factor. An additional aspect that is most often overlooked when assessing the significance of impacts is its context. Impacts that are the same in magnitude and likelihood can be considered more or less important, influence decisions to a greater or lesser extent, depending on where exactly they take place, how they are perceived by stakeholders, what is the current social environment, etc. .
There are many methods for assessing significance: for example, N. Li describes 24 methods. The simplest and most commonly used method for assessing significance is to compare them with universal standards. Standards can be quantitative (for example, maximum allowable concentrations of pollutants) or be qualitative in nature (for example, restrictions on certain types of economic activity within a specially protected natural area or near cultural monuments). However, there are important limitations to the applicability of the standards for assessing significance:
- there are no standards for many exposures (for example, at the time of this writing, there was no standard for dioxin concentrations or releases in Russia);
- many standards are based on approximate data (insufficiently verified, inaccurate or incomplete) and thus their scope is limited;
- the standards are based on the notion of "threshold impact", while many types of exposure (for example, ionizing radiation) do not have a threshold value: it is possible that their influence manifests itself at arbitrarily small values;
- standards are not always suitable for taking into account indirect, cumulative impacts, the synergistic effect of several factors;
- standards are rarely applicable to account for the unique conditions specific to a particular situation.
Very close to the comparison with the standards is the method of assessing the significance, based on a comparison of the magnitude of the impact with the average values of this parameter for the area under consideration. Such a method introduces an element of "context" into the assessment of significance, taking into account the local situation. This type of methods includes the comparison of parameters of the state of the environment with background values. Comparing impact magnitudes to standards or representative values is an "objective" method of assessing the significance of impacts (although standards can, of course, be considered subjective).
Objective facts testify to the existence of a close influence of environmental factors on the biotic processes of the ecosystem (population density, dynamics of species structure, behavioral characteristics). Environmental factors such as light, temperature, water regime, biogenic elements (macro- and microelements), salinity, and others are of functional importance for organisms at all major stages of the life cycle. However, it is possible to use the inverse pattern and judge, for example, by the species composition of organisms about the type of physical environment. Therefore, “bioindication is the determination of biologically significant loads based on the reactions of living organisms and their communities to them. This fully applies to all types of anthropogenic pollution.”

Conclusion
And local levels of monitoring. It is carried out with the help of television images, photographs, multispectral images, etc. obtained from spacecraft, as well as by collecting data from land and sea stations. Space monitoring makes it possible to promptly identify the sources and nature of environmental changes, trace the intensity of processes and amplitudes of ecological shifts, and study the interaction of man-made systems. A monitoring service has been established in many countries; 1988 The World Conservation Monitoring Center (WCMC) was organized.
