| Description
| - Emissions from base metal smelter are important sources of metal pollution of soils. The project focuses on investigation of geochemical processes governing the reactivity and kinetics of dissolution of air-pollution-control (APC) residues in soil environments in order to predict the release, mobilisation and fate of inorganic contaminants (Pb, Cd, Zn, As, Sb). First part of the project will focus on long-term leaching tests in simulating soil solutions (citrate, HA and FA) combined with mineralogical investigation of newly formed products and thermodynamic modeling of metal complexation with DOC (WHAM, ECOSAT). The second part will investigate the long-term mobility of inorganic contaminants in residue-spiked soil at experimental field.Time-depedent changes in speciation, chemical fractionation and mobilisation of contaminants in soils and soil water will be studied. The third part of the project will be devoted to long-term laboratory pot experiments on residue dissolution in soils (en)
- Hlavním zdrojem znečištění půd v hutních oblastech jsou emise z metalurgických závodů. Projekt se zaměřuje na studium geochemických procesů ovlivňujících reaktivitu a kinetiku rozpouštění popílků z metalurgie Pb v půdním prostředí za účelem predikce uvolňování, mobilizace a záchytu anorganických kontaminantů (Pb, Cd, Zn, As, Sb). První část projektu bude zaměřena na dlouhodobé loužící testy v simulovaných půdních roztocích (roztok citrátu, HA a FA) kombinované s mineralogickým studiem novotvořených produktů a termodynamickým modelováním kompletace kovů s DOC (WHAM, ECOSAT). Druhá část je zaměřena dlouhodobou studií mobility kovů v reálné, popílkem kontaminované půdě experimentálního pole. Výzkum bude zaměřen na časové změny ve speciaci, chemické frakcionaci a mobilizaci kontaminantů v půdě a ve vzorcích půdní vody. Třetí část projektu bude zaměřena na laboratorní nádobový experiment rozpouštění popílku v uměle kontaminovaných půdách s odlišnými pedogenními vlastnostmi. Výsledky přispějí ke
