  • Some features of the ecological situation of The Miussky estuary

    The ecological state of the Miussky estuary – the most important water object from the point of view of reproduction and cultivation of the fish which is territorially located in an ancient mouth of the channel of the river Mius and connected with Taganrog Bay of the Azov sea is considered. The uniqueness of the water body lies in the fact that the natural waters of The Mius estuary make up the flow of the river Mius mixed with the sea waters of the Taganrog Bay, especially during periods of strong upland phenomena caused by weather conditions. The data of hydrochemical monitoring for 2016-2018 are used for the assessment, the dynamics of water quality changes according to the UKIZV index is considered and the component-by-component analysis of the concentrations of indicators that have the greatest impact on the negative ecological state of the water body is carried out.

    Keywords: MPC, Miusskaya estuary, water quality, UKIZV, aluminum, Fe, petroleum products (PP)

  • Valuation quality of water by hydrochemical indicators in water intakes places of Taganrog.

    The main contence of this article is a valuation quality of water in water intakes places of Taganrog. A specific combinatory index of pollution of water is used for valuation quality. In this article is considered dynamics of the main polluting substances around water intakes.

    Keywords: maximum permissible concentration specific, combinatory index of water pollution, quality of water, critical indicators ofwater pollution, sulfates

  • Simulation model of silica biosensors for environmental studies

    The urgency and feasibility of application of biosensors with active biological layer for environmental studies was justified. A study of biosensors of various configurations to build a test system of environmental pollution control and determine the degree of aquatic toxicity was conducted. A simulation model of biosensor system was built. The selectivity of the biosensor was determined by theoretical experiments in which the analytical signal of the biosensor for biologically active layer without other biologically active substances was determined. The relationship between the type of transducer and biologically active substance was revealed. The software implementation of bisensor system was developed that reveals a number of pollutants and allows using not only different converters, but also different strains.

    Keywords: biosensor, strain, quartz crystal, simulation model, environmental studies, pollutants, toxicity, sensitivity

  • Structural design of information and measurement systems for biopotential research

      The mathematical features of construction information and measuring health systems (IMS). Because biological systems are complex, not always well-defined structure, for their correct description and implementation of metrological analysis requires its imposition. Accordingly, the presentation described bioinstrumentalnoe MIS. Within the theory of metrological synthesis formulated the concept of IMS core. With the use of the mathematical theory of categories and object-oriented modeling describes the basic relationships between the elements of the core IMS. The basic position with regards to the construction of MIS based on its structure. A scheme of the developed system of environmental monitoring of water environment on the basis of an integrated assessment of water quality. The main components of the system were presented. Feature of the developed system is the consideration of non-fixed sources of pollution, which was made possible thanks to the developed method of integral evaluation.

    Keywords: Measuring health system, object-oriented modeling, method of integral evaluation

  • Biotest system for monitoring water in Taganrog Bay

    Biotest system was developed, which combines the standard chemical analytical methods and express biotest analysis. As a part of the system the geographic information system, which allows for an integrated approach to the assessment and ranking of all types of pollution sources based on their interaction, as well as to identify the most hazardous pollutants from the standpoint of environmental regulation was applied.

    Keywords: biotest system, biotest analysis, geoinformation system

  • Experimental studies of the dynamics of the concentration of heavy metals in surface water in the Taganrog Bay

    Based on a previously developed system of environmental monitoring experimental studies of the dynamics of heavy metal concentrations in surface water in the Taganrog Bay of the Azov Sea were carried out. Sampling points were determined. Data processing for the heavy metals such as iron, copper, molybdenum, nickel, lead, chromium was provided. Observation period - 10 years. Trends have been defined for each point of observation.

    Keywords: experimental data, dynamics of concentration of heavy metals

  • Experimental studies of heavy metal pollution in sediments in the Taganrog Bay

    Based on a previously developed system of environmental monitoring experimental studies of the dynamics of heavy metal concentrations in sediments in the Taganrog Bay of the Azov Sea were carried out. Sampling points were determined. Data processing for the heavy metals such as iron, copper, molybdenum, nickel, lead, chromium was provided. Observation period - 10 years. Trends have been defined for each point of observation.

    Keywords: pilot studies, dynamics of concentration of heavy metals, pollution of waters, ground deposits
