[A case study of the contents of radionuclides and of main chemical pollutants in the atmospheric air of Moscow].
The article contains data on monitoring the atmospheric air pollution in Moscow. Thus, the below figures are presented: beta ranges from 2.6 E-0.5 to 5.7 E-0.04 Bk/m3, airborne pollutants amount to 3-80 mkg/m3, sulfates--0.002-1.58 mkg(S)/m3, nitrates--0.05-0.75 mkg(N2)/m3 ammonium ions--0.12-1.20 mkg (N2)/m3, sulfuric dioxides--0.11-1.20 mkg (S)/m3. nitric dioxides--0.05-0.5 mlg (N2)/m3 and nitric acid--0.01-0.08 mkg (N2)/m3. The concentration of airborne pollutants exceeds the regional European level (22 mkg/m3) and that of Russia's European part (12 ... 28 mkg/m3) approximately by 1.5 times. It is noteworthy that it reaches 50 ... 70 mkg/m3 in large industrial centers of Europe. The share of sulfuric and nitric acids in the total concentration of airborne pollutants is (by weight) 13%. 0.8 g of sulfur per m2/year and 0.34 g of nitrogen per m2/year fall in the area of Sport-and-Recreation Complex No. 3 with precipitations; the average total beta-activity of atmospheric precipitations amounts to 1.2 Bk/m2 per day. An analysis of relationships between the air dustiness, the ashes samples' weight (of the air) and cuvette (precipitations) is indicative of their direct and tense correlation: the correlation coefficient between dust and ashes samples is 0.716, and between dust and ashes samples of cuvettes--0.559. At the same time, an extremely weak correlation should be pointed out between air dustiness and the total beta-activity of samples--the correlation coefficient is 0.184 (during a warm year season), as well as between dustiness and the beta-activity of cuvettes--0.346.
