Journal ArticleDOI
Efficiency of green waste compost and biochar soil amendments for reducing lead and copper mobility and uptake to ryegrass.
TL;DR: Green waste compost and biochar amendments were assessed for their assistance in regulating the mobility of copper (Cu) and lead (Pb) and the resultant uptake of these metals into vegetation and harvestable amounts of Pb were reduced.
Journal ArticleDOI
Arsenic and heavy metal mobility in iron oxide-amended contaminated soils as evaluated by short- and long-term leaching tests.
TL;DR: The conclusions were that whilst Fe-oxides may be used as effective in situ amendments to attenuate As in soils, their effects on other trace elements, such as Pb and Cd, require careful consideration.
Journal ArticleDOI
Arsenic mobility in brownfield soils amended with green waste compost or biochar and planted with Miscanthus.
TL;DR: In pot experiments, As mobility was investigated in three different brownfield soils amended with green waste compost or biochar, planted with Miscanthus, and the impacts of both amendments on SOC, Fe, P and pH are likely to be critical in the context of As leaching to ground water.
Journal ArticleDOI
Field trials to assess the uptake of arsenic by vegetables from contaminated soils and soil remediation with iron oxides.
TL;DR: A proposed remediation treatment comprises the precipitation of iron (Fe) oxides in the contaminated soil by adding ferrous sulfate and lime to reduce the uptake of arsenic (As) by plants from contaminated soils.
