Certain patterns of zinc, copper, and lead redistribution across the structural fractions of Chernozems and Urbic Technosols.

The purpose of this work was to study the patterns of Zn, Cu, and Pb distribution in soil aggregates of various size fractions. Materials were Calcic Chernozems and Urbic Technosol of the Rostov agglomeration. Soil samples were passed through sieves with different mesh sizes (dry sieving).
