The objective of this research was to determine the heavy metal concentration in soils of a topolithosequence in western Minas Gerais State, in order to evaluate their potential availability in soils originated from distinct parent materials. Seven soil samples were collected, air dried, and sieved through a 2 mm sieve and then had their Cd, Cu, Pb, and Zn contents determined. The total concentration of the chemical elements was assessed using HNO3/HClO4 extractant (4:1 by volume). The soluble forms were analyzed […]
