Project summary

The simultaneous presence of high quantity of unhealthy chemical substances, radioactive and electromagnetic radiations, dust etc. in the environment calls for complex approach to monitoring system. Meanwhile the integrated index of air pollution exists only for chemical substances. Obviously both intensity and various set of environment parameters has harmful effect upon the human health state. At the same time available automated systems of environment control and monitoring worked out by SPECTRO Analytical Instruments, Carl Zeiss lena GmbH, Koch & Nagy, Strohlein GmbH & Co (all Germany), Perkin-Elmer (USA) are supposed only to control the environment over about 10 chemical compounds and some microclimatic parameters. Besides, the cost of above-listed monitoring systems is more than $200,000.

Objective of the present Project is to develop a small-scale automated control system which allows not only to conduct automated measurements of various environmental parameters, but also to provide an integrated environmental qualitative analysis in some conditional units ( 'comfort units) using a mathematical model developed under the project on the basis of concepts approved by foreign experts.

The basis for methodical approaches of environment quality evaluation was approved by the foreign experts:

expert group (18 persons) in Czechia, the Prague Institute for Hygiene and Epidemiology;

expert group (23 persons) in Germany, the Institute for Hygiene of Academy of Medical Sciences in Erfurt and was described in the additional information of the Project in scientific documents N10-13.

Developed monitoring system will consist of small-scale modules with various sensors which are able by themselves to control automatically and to transfer obtained data to the main terminal on the demand from the working station of control service according to the pre-set program.

Evaluation of space will be made keeping in mind its functional purpose (industrial, working or residential area). The evaluation will allow to make conclusion on the optimal conditions for personnel stay in the building or to decide if there is a need to change occupational destination of the building. The complex system cost is approximately $40,000.

The environmental control assumes that measurements are made for a number of critical (concerning their hygienic value) chemical agents (H2S, C12, CO2, NOx, SOx, H2); mercury vapours; microclimatic parameters-temperature, relative humidity, pressure, air mobility; dust content; electromagnetic radiation pursuant to the MPR II Standard (it was adopted by the Sweden National Committee on Measurements and Tests in 1990) and static electricity; dose rate of external gamma-radiation; radioactive gases-radon and thoron, since their contribution to the effective equivalent dose formed by all radiation sources is more than 60% and, besides, in certain conditions they may cause lung cancer. During project implementation it will be possible to expand the range of assessed parameters.

The architecture of the developed monitoring system will have three-level structure.

The first level of the system includes the certain quantity of tiny gauges(sensors) developed by the specialists in this country as well as abroad. Defined combination of portable sensors in a separate modulus weighting as much as 6 kg will allow to change the architecture of all system easily, to locate them correctly over the object under control and to carry out the environmental monitoring with regard to various factors which affect or can affect on the ecology of controlled object.

The second level of the system contains the pre-set quantity of low-consuming universal microcontrollers able to accumulate automatically, to process partially and to store the preliminary information obtained from the sensors as well as to transmit this information on demand to the third level-to the Main Unit (or working station of the operator of control service).

The first and the second levels of the system form its modulus. The quantity and location of the modules are determined by chosen methodological approach Such approach allows to automate monitoring process and to reduce number of servicing personnel to 1 person; to ensure correct solution of the monitoring task providing optimal location of microcontrollers with sensors through the site of the examined object depending on its area, space and air-exchange recurrence; to prevent installation of network cables and ,as a result, to expand the range of ecological tasks.

A multifunctional nature of the being designed control system based on the modular principle of its formation and quantity of chosen detectors, its small dimensions and low weight and quick (express) measurements will allow any company, organisation or ecological committee having such a system to perform quick inspection and control and complete monitoring of various objects based on parameters of their interest.

The mobility of the system being developed is based on its three-level structure and allows to carry out setup assembling (disassembling) reasonably quickly, to change the quantity of the air-environment parameters being measured as applied to concrete problem of one or another object monitoring.

The tactics of creating of the air-environment monitoring system is based on using of already existing completed projects from the view-point of methodological approach, as well as, from the view-point of creating of reliable and usually portable means for various air-environmental parameters measuring. This will allow to complete the Project in two years successfully and to create cheap sample of air-environment monitoring system enabling to inspect all objects of interest effectively ( quickly and complexly)

In the course of the Project execution one complete set-up of the monitoring system will be prepared, its climatic tests and natural inspections of the scientific-research reactor of MPhEI will be conducted, new long-term electronic modules will be developed, the methodological aspects of ecological-hygienic examination of controlled objects will be worked out.
