Abstract.
Objectives. To develop the classification of coal and black oil ashes of various deposits, taking into account the qualitative and quantitative composition, the nature of the biological action and to substantiate the maximum permissible concentration (MPC) for its various kinds.
Material and methods. The quantitative and qualitative content of metals was studied in the ashes of five types of coal and black oil. The classification of black oil and coal ashes from various deposits was carried out taking into account the developed complex integral index ΣKi. The study of the nature of the biological effect and the substantiation of the MPC was carried out for the ashes of Ekibastuz coal and black oil according to the principle of a 4-month chronic experiment. The biological effect of the ashes was studied observing the behavior of animals and the dynamics of their mass, the summation-threshold index (STI), the activity of a number of enzymes.
Results. The component composition of various kinds of ashes and ashy biological effect under the chronic experiment conditions were studied. The levels of threshold and subthreshold concentrations for black oil and Ekibastuz coal ashes were determined. Taking into account the content of vanadium pentoxide (V2O5) in the black oil ashes, the daily maximum permissible concentration (MPC) was substantiated. The general hygienic characteristics of the thermoelectric power station (TPS) as a source of atmospheric pollution was given.
Conclusions. It has been determined that the ashes of black oil and Ekibastuz coals on continuous inhalation body intake (4 months) possess polytropic effect. Taking into account the V2O5 content in black oil, the average daily MPC was substantiated, it made up 0,002 mg/m3.
Key words: thermoelectric power station, atmospheric air, classification of different kinds of ashes, biological effect of ashes.
