Abstract: [cze] [eng]
Studie se zabývá stanovením obsahu a chemických forem Hg v různě kontaminovaných půdách ČR. Nejvyšší koncentrace Hg byly zjištěny ve svrchních půdních horizontech, s rostoucí hloubkou a klesajícím obsahem humusu se koncentrace snižovaly. Termodesorpční analýza dobře rozlišila slaběji vázanou Hg2+ na jílové minerály od Hg vázané na organickou hmotu či sulfidy. The study deals with the determination of Hg distribution and speciation in soils with different level of contamination in the CR. The highest concentrations of Hg were found in topsoil horizons and declined with increasing depth and decreasing content of humus. Thermodesorption analysis distinguished Hg2+ weakly bound to clay minerals from Hg bound to organic matter or sulfides.
