In article realizes the space- temporary analysis and form causes change of the analyze components at the chemical structure of precipitations in the north of the Russian plain. This article uses the method of the correlation analysis of this macrocomponents between meteostations of European north; also make a construction equation of the linear regression for analytical macrocomponents at the atmospheric precipitations of the region. In this work are discover and denote back ground and so-called post- back ground period in the distribution concentration of sulfate-and hydrocarbonate ions on the meteorological stations of the European part of Russia from 1991 to 2011 years. It’s established that so-called back ground level of the maintenance of SO42- and HCO3- in a chemical composition of an atmospheric precipitation of the region where values of their concentration are in limits of 0,5–5,5 mg/l, is characteristic for meteorological stations in Sura and Brusovitsa. Whereas extreme SO42 values – in a precipitation, of the XX century reaching in the late nineties more than 60 mg/l, Cherepovets, Ukhta are recorded on the meteorological stations located in the cities of Arkhangelsk. Domination a hydrocarbonate ion as a part of a precipitation on a meteorological station Ukhta in the mid-nineties of last century (37–42 mg/l) was revealed. And in a type of that the maintenance of HCO3- in a precipitation is the CO2 level indicator, the assumption of influence of an anthropogenous factor in distribution of concentration of this ion to meteorological stations in Ukhta was made. The main sources of pollution of the air pool of CO2 of the city are the enterprises coal-mining, gas, oil and gas, heat power and other industries. Besides, there was an established fact of essential decrease in concentration sulfate – and hydrocarbonate ions in a chemical composition of an atmospheric precipitation of the region of the North of East European Plain in the first decade of XXI century.
