Heavy metal speciation and mobility assessment of arid soils in the vicinity of Al Ain landfill, United Arab Emirates

Potential for enhanced phytoremediation of landfills using biosolids – a review

“…This indicated that metal availability was dependent on the source of the waste. In addition, the generally high pH and high concentrations of DOC in leachate, which is a principal carrier of heavy metals from waste, would result in speciation of heavy metals in complexed or insoluble forms which are less accessible to plants and biota (Baun and Christensen, 2004;Howari, 2004). Therefore, the innate properties of heavy metals together with common landfill conditions may result in an equilibrium shift and repartitioning of metals between the solid and solution phases enabling a revegetation strategy for landfill rehabilitation to be successful due to reduced metal toxicity.…”

Fluctuation of dissolved heavy metal concentrations in the leachate from anaerobic digestion of municipal solid waste in commercial scale landfill bioreactors: The effect of pH and associated mechanisms

“…The majority of these studies present snapshots of heavy metal speciation in leachate with discrete ages from either operating or closed mature landfills [6,[11][12][13][14][15][16].…”

Assessment of the Relative Adequacy of Landfills as a Means of Solid Waste Disposal in Malaysia

“…Several studies have been conducted dealing with the generation and treatment of leachate [2][3][4][5][6][7][8][9]. The presence and treatment of hazardous materials in leachate like heavy metals and volatile organic compounds which may escape into surrounding water bodies like rivers have also been studied [10][11][12][13][14]. Rivers need cleaning-up and [15] landfill gases must be controlled to protect property and public safety.…”
