This study assessed the suitability of Phragmites australis and Arundo donax for the aided phytostabilization of metal(loid)s in polluted soils treated with an iron-rich water treatment residue (Fe-WTR), a municipal solid waste compost (MSW-C) and their combination (Fe-WTR+MSW-C). The three soils under study (S1, S2, S3) showed very high total concentrations of As (from 371 to 22,661mg·kg−1 d.w.)...
Two different amendments, an iron-rich water treatment residue (Fe-WTR), a municipal solid waste compost (MSW-C) and their combination (Fe-WTR+MSW-C) were added at different rates (from 2 to 4% w/w) to three mining soils (S1, S2, S3) mainly polluted with As (from 371 to 22,661mg·kg−1d.w.) and different co-occurring trace metals (i.e. Pb, Zn and Cu) to evaluate their effectiveness as metal(loid)s-immobilizing...
In this paper we evaluated the effects of various amendments, notably zeolite, red mud (a by-product of aluminium manufacturing) and lime on decreasing the bioavailability and phytotoxicity of Pb, Cd and Zn present in a contaminated acidic soil (pH=4.2). Pisum sativum and Triticum vulgare were grown in a glasshouse experiment on untreated-polluted (control) and amended soils and their yield and metal...
In this study we compared the efficiency of different amendments, notably red mud (a bauxite residue), natural zeolite and lime, to immobilize the heavy metals present in a polluted acidic soil [Pb (3266 mg kg −1 d.m.), Cd (35.4 mg kg −1 d.m.) and Zn (1495 mg kg −1 d.m.)] and to influence several microbiological properties. The addition of all the amendments decreased significantly...
