Mobile fractions in dustfall and possible migration of metals to soil / Badania mobilnych frakcji metali w opadzie py?owym i mo?liwo?? migracji metali do gleby

摘要

The atmospheric fallout over the Rzeszów town was investigated. Intensity of dustfall (quarterly periods, 2011.2012) and its physicochemical properties (acid-base character, solubility and sequential solubility, mobile fractions) were investigated. The intensity of dustfall was variable from 25 to 83 g·m.2 and depended on the season. Contents of metals in precipitation were diverse with quantities exceeding 1%: Fe, K, Ca, Na, in 0.1.1%: Mg, Zn, Na, Ca, Mn, Ni, Co, Cr, and less than 0.1%: Cu, Bi, Cr, Mn, Ni, Pb. It was found that the dustfall is a possible source of metals. The atmospheric fallout can enlarge a pool of metals in soils from 0.18% up to 80%.
