Impact of earthworms on trace element solubility in contaminated mine soils amended

16 The common practice of remediating metal contaminated mine soils with compost can reduce 17 metal mobility and promote re-vegetation, but the effect of introduced or colonising 18 earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 19 mgAs kg and 362 mgCu kg) and Pb/Zn mine (4550 mgPb kg and 908 mgZn kg) with 0, 20 5, 10, 15 and 20 % compost and then intro...

Impact of earthworms on trace element solubility in contaminated mine soils amended with green waste compost.

The common practice of remediating metal contaminated mine soils with compost can reduce metal mobility and promote revegetation, but the effect of introduced or colonising earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 mg As kg(-1) and 362 mg Cu kg(-1)) and Pb/Zn mine (4550 mg Pb kg(-1) and 908 mg Zn kg(-1)) with 0, 5, 10, 15 and 20% compost and then in...

Potential of Eucalyptus camaldulensis for phytostabilization and biomonitoring of trace-element contaminated soils

Soil pollution by trace elements (TEs) from mining and industrial activity is widespread and presents a risk to humans and ecosystems. The use of trees to immobilize TEs (phytostabilization) is a low-cost and effective method of soil remediation. We aimed to determine the chemical composition of leaves and flower buds of Eucalyptus camaldulensis in seven sites along the Guadiamar River valley (...

Quality of trace element contaminated soils amended with compost under fast growing tree Paulownia fortunei plantation.

The use of fast growing trees could be an alternative in trace element contaminated soils to stabilize these elements and improve soil quality. In this study we investigate the effect of Paulownia fortunei growth on trace element contaminated soils amended with two organic composts under semi-field conditions for a period of 18 months. The experiment was carried out in containers filled with tr...
