Abstract
The aim of these studies was to determine solubility and availability of the heavy metals in soil using single extraction procedure. The acid extractants: 1 M HCI, 10% HNO, and 0.43 M CH,COOH were tested as eluents. Extracting capacity of inorganic acids were higher than 65% of total Pb and Zn and hardly depended on their total content. Acetic acid leached less than 5% of total Cu, Ni and Pb. A statistical analysis showed that physico-chemical soil parameters affected heavy metals solubility in acids eluents. Single extraction in acid solution is a simple way to determine the soil contamination with heavy metals.
