Abstract

. The study presents the results of measuring of microelements’concentrations (heavy metals) in the soil of territories surrounding the heat power plant of Bishkek city (Kyrgyz Republic). Measurements are done by a method of atomic emission spectral analysis inside the two-jets (DGP-50) plasmatron’s plasma flow. An improvement in the method’s sensitivity, rapidity as well as repeatability was ensured by applying a multichannel optical spectrum recorder, operating on the basis of a photoelectronic cassette and a high-resolution spectral apparatus. Results of heavy metals concentrations, obtained at a distance between 100 – 1000 m from the pollution source show small excess of microelements’ content at the local spots of analysis. This pattern of soil cover’s pollution might be characterized by the specified source’s emission rate and its conditions, as well as the meteorological situation.
