| Description
| - Silně kontaminované lesní a orné půdy a říční sedimenty z Příbramska byly extrahovány deionizovanou vodou, roztokem chloridu vápenatého, dusičnanu amonného, nebo DTPA. Výsledky byly diskutovány vzhledem k termodynamické stabilitě formě kovových iontů a jejich případné resorpce na zkoumanou půdu nebo sediment. (cs)
- Highly polluted forest/tilled soils and stream sediments from a mining and smelting area were subjected to single-extraction procedures to determine the extractable contents of Cd, Cu, Pb, and Zn. The results obtained from four widely used operationally defined single extraction tests were compared. The analytical data were coupled with measurement of the pH and Eh in extracts, mineralogical investigations and thermodynamic modelling using the PHREEQC-2 code. The changes in the pH of the equilibrated suspensions significantly influenced the metal extractabilities, with higher values in the lower pH regions. Although the DTPA procedure generally extracted the highest amounts of metals, it was found to be unsuitable for highly organic acidic forest soils, where anionic metal–DTPA complexes are assumed to be re-adsorbed on the positively charged surfaces of soil organic matter and oxides.
