Bioremediation of a soil contaminated with radioactive elements

Characterization and remediation of soils contaminated with uranium

“…The excavation and transportation of the heavily polluted soils to specific depositories is still a common practice in most countries [34].…”

“…The treatment was connected with the dissolution of the contaminants in the upper soil horizons and their transfer into the deeply located soil horizons, where they were immobilized as different insoluble compounds as the result of the action of some aerobic microorganisms [34,142]. Also, the immobilization was ascribed to the anaerobic sulfate-reducing bacteria.…”

Geostatistical risk estimation at waste disposal sites in the presence of hot spots

“…Mining and beneficiation of coal and mixed sulphide ores often generates hazardous solid wastes and acidic leachates that contaminate soil, surface-and groundwater and cause severe environmental and health impacts [1][2][3][4][5][6][7][8][9].…”

Solubilization of heavy metals from a fluvial AMD generating tailings sediment by heterotrophic microorganisms

“…In some cases, heterotrophs were investigated for their capability to bioleach metals from ores, minerals (Rossi, 1978;McKenzie et al, 1987;Portier, 1991;Sukla and Panchanadikar, 1993;Steemson et al, 1997;Styriakova et al, 2003) and waste materials (Hahn et al, 1993;Willscher and Bosecker, 2003). Other studies focused on their potential use to decontaminate soils (Karavaiko and Groudev, 1985;Francis and Dodge, 1990;Rusin, 1992;Bock and Bosecker, 1996;Bosecker, 1999;Groudev et al, 1999). In most of these works, mixed cultures of heterotrophs were used to examine the weathering and leaching behavior (Wagner and Schwartz, 1967;MeunierLamy and Berthelin, 1987;McKenzie et al, 1987;Sukla and Panchanadikar, 1993;Hahn et al, 1993;Steemson et al, 1997;Styriakova et al, 2003).…”
