SYGNAL COMPONENTS OF ATMOSPHERIC SUSPENDED MATTERS. PART II. MICROPARTICLES OF METALS

Abstract

The article is about the metallic microparticles being the main air pollutants of modern cities. The work demonstrates microparticles of the metals found in the samples taken from the fresh snow and dry-air suspended matters taken in different areas in the cities of the Far East of Russia (Vladivistok, Khabarovsk, Blagoveshchensk, Birobidzhan, Ussuriysk, Nakhodka and Belogorsk). In native samples with the help of scanning electronic microscopy nano- and microparticles of Fe, Pb, Ba, Zn, Cr, Ti, Zr, Cu, Bi, W, Mn, Sr, Co, Ni, Mo, Ag, Au, Pd, Pt and other metals were found and identified in reflected electrons. It was found out that particles of Fe, Pb and of precious metals (Au, Pd, Pt) being the part of catalysts were typical for the samples taken near transportation junctions. The most widespread particles (Fe, Pb, Ba, Zn) make up 70-80% from the found ones.
