Aided phytoextraction of Cu, Pb, Zn, and As in copper-contaminated soils with tobacco and sunflower in crop rotation: Mobility and phytoavailability assessment

Abstract: Copper-contaminated soils were managed with aided phytoextraction in 31 field plots at a former wood preservation site, using a single incorporation of compost (OM) and dolomitic limestone (DL) followed by a crop rotation with tobacco and sunflower. Six amended plots, with increasing total soil Cu, and one unamended plot were selected together with a control uncontaminated plot. The mobility and phytoavailability of Cu, Zn, Cr and As were investigated after 2 and 3 years in soil samples collected in these eigh… Show more

“…The evolution of SPW pH with time was assessed, revealing that in almost all conditions (except PM and PBM), SPW pH decreased with time, between 0.6 and 0.8 units, and with no effect of plant growth. Such decreases with time have been observed previously (Hattab-Hambli et al 2016, Marseille et al 2000, and explained by the oxidation/acidification of the substrates due to watering. Non-amended Pontgibaud technosol presented a low EC at T0 (210 µS.cm -1 ), which increased following amendment application, except for with biochar alone (Table 3).…”

“…On the other hand, they are not in full agreement with results reported by Cheng and Hseu [39] and Hattab-Hambli at al. [40], who did not observe changes in the soil pH after the application of inorganic zeolite, bentonite and dolomite into soil.…”

“…It underscored the necessity for adequate water treatment and appropriate remediation techniques to mitigate metal accumulation in crops. Additionally, Hattab-Hambli et al (2016) managed coppercontaminated soils through aided phytoextraction in field plots, implementing a crop rotation of tobacco and sunflower [71]. Their investigation into the mobility and phytoavailability of Cu, Zn, Cr, and Pb over two and three years revealed a decrease in total concentrations in the soil pore water, likely attributable to annual plant shoot removals and leaching.…”
