Contrasting mobility of arsenic and copper in a mining soil: A comparative column leaching and pot testing approach

Popis výsledku v původním jazyce

The remediation of legacy metal(loid) contaminated soils in-situ relies on the addition of (organic) amendments to reduce the mobility and bioavailability of metal(loid)s, improve soil geochemical parameters and restore vegetation growth. Two vermicomposts of food and animal manure waste origin (V1 and V2) were amended to an arsenic (As) and copper (Cu) contaminated mine soil (up to 1500 ppm). Leaching columns and pot experiments evaluated copper and arsenic in soil pore waters, as well as pH, dissolved organic carbon (DOC) and phosphate(PO4) concentrations. The uptake of As and Cu to ryegrass was also measured via the pot experiment, whilst recovered biochars from the column leaching test were measured for metal sorption at the termination of leaching. Vermicompost amendment to soil facilitated ryegrass growth which was entirely absent from the untreated soil in the pot test. All amendment combinations raised pore water pH by approx. 4 units. Copper concentrations in pore waters from columns and pot
