FIELD: physics; measurement. ^ SUBSTANCE: invention is related to ecological geophysics, in particular, to methods for monitoring of aerogenic contamination of environment. Snow samples are taken in points that are located at the distance of more than 30 m from anthropogenic objects. Samples are melted, hard fraction is obtained by means of filtering. Amounts of every metal are determined in hard fraction. Values of load are calculated, which are created by supply of every metal into environment, then they are compared to background values, and total indices of load ZP are calculated. Besides, differential magnet filters are measured with deposited dust fraction. Values of magnet load are calculated, compared to background values. Coefficients of relative increase of magnet load KPM are calculated. Representative sample with size sufficient for statistic analysis is made from total combination of kPM values. In filters that are related to sample, amount of every metal is defined by method of atomic emission spectrometry with inductive-bound plasma. Regression analysis of dependence is carried out between KPM and ZP values in sample. Regression equation of ZP per KPM is found, which is used to calculate ZP values for the whole combination of KPM values. ^ EFFECT: higher reliability. ^ 6 dwg |
