Metal-contaminated soil remediation by using sludges of the marble industry: Toxicological evaluation

Deposition of heavy metals from particulate settleable matter in soils of an industrialised area

“…High levels of metals that for example, can be found in mine wastes around disused metalliferous mines may provoke adverse environmental effects since they can be discharged and dispersed into nearby agricultural soils, food crops and stream systems (Pérez-Sirvent et al, 2007). The increased concentrations (0.1% or higher) of metals such as Cu, Zn, Pb, Co, Ni, Cd and As in soils are known to be strongly selected for uptake by natural vegetation (Bech et al, 1997).…”

Metal immobilization in hazardous contaminated minesoils after marble slurry waste application. A field assessment at the Tharsis mining district (Spain)

“…A number of additives have been tested as feasible soil amendments for immobilization of trace metals, including liming materials [15][16][17][18], phosphate [19], clay minerals [20], iron oxyhydroxides [21], zeolites [22,23], beringite [24], coal fly ash [25] and alkaline composted biosolids [26]. Most of these studies have shown positive effects of amendment application under controlled laboratory conditions, but there is still concern regarding the behaviour of trace elements in amended soils under field conditions, and the long-term performance of the in situ amendment.…”

Current Status of Trace Metal Pollution in Soils Affected by Industrial Activities

“…High levels of metals discharged from mine wastes may cause adverse environmental effects, because they can be dispersed into nearby agricultural soils and stream systems and taken up by food crops [64]. Among the 17 references dealing with metal pollution in mining and smelter sites, 4 elements (Cu, Cd, Pb, and Zn) stood out as the most common choice of target analyte.…”
