METHOD FOR THE QUANTITATIVE DETERMINATION OF ELEMENTS FOR STUDYING THE DISTRIBUTION OF AIR POLLUTANTS IN THE SURROUNDINGS OF AN EMISSION SOURCE

摘要

The object of the invention is a method for quantitatively determining elements for studying the distribution of air pollutants in the surroundings of an emission source. The method is characterized by the following steps: the sample to be examined is collected at a sampling plot from the plant cover surrounding the emission source, by taking the sample from a surface portion thereof, at that side of the sampling plot which faces the emission source; the sample is dried; the surface of the sample is made electrically conducting; the contents of the elements deposited on the surface of the sample are measured using an energy dispersive X-ray microanalyzer (EDX) connected to a scanning electron microscope (SEM).
