Combined mild soil washing and compost-assisted phytoremediation in treatment of silt loams contaminated with copper, nickel, and chromium

Feasibility of using peanut (Arachis hypogaea L.) for phytoattenuation on lead-contaminated agricultural land—an in situ study

“…Previous studies have shown that Brassica genus plants (e.g., rape plants) can accumulate high concentrations of heavy metals in plants and are considered heavy metal hyperaccumulators (Ginneken et al, 2007;Houben et al, 2013;Sung et al, 2011). Therefore, in this study, rape was grown for comparison.…”

Analysis of efficacy of the process of remediation of landfill site soil contaminated with leachate using material flow analysis

“…Within the ex-situ system of Scenario 2, and based on book values, the value of efficacy of the reduction of the flow of cadmium through the method of soil washing amounts to 55 %, while through the method of vitrification, executed while performing field testing amounts to 70 % (Thompson et al, 1992;Kos and Leštan, 2003;Pociecha et al, 2011;Sung et al, 2011).…”

“…Within the landfill body, with potential for collecting and/or infiltration in groundwater aquifer only 5-15 % of the landfill filtrate remains, carrying with it 15 % of the initially generated concentration of cadmium, namely 219,622 g/year or 219.62 kg/year (Miloradov, 2006). Value of efficacy of the reduction of cadmium concentration by applying ex-situ method of washing soil was adopted on the basis of book data, namely the value of efficacy of the reduction of heavy metals achieved through field testing, which amounts to 55 % was applied (Kos and Leštan, 2003;Pociecha et al, 2011;Sung et al, 2011). Accordingly, after implementation and execution of the said treatment, treated land and clean water are obtained as final products.…”

Chemical and Allied Products

“…viscosa and vermicompost were used in conjunction, the soils were rid of TCE in such a way that considering the eco-physiological profile, the authors concluded that it was better than soil not contaminated with TCE. Sung et al (2011) combined phytoremediation as the central treatment process along with soil washing for the purpose of removing plating wastewater with Cu, Ni, and Cr. Having observed treatment for over 4 months, it was determined that rapeseed had performance of removing the metals from the soils as it was determined that the roots and shoots of plants had contained the high concentration of metals.…”
