“…In our case, the soil C:N ratio was over 50 for site B, indicating poor conditions for organic material decomposition and nutrient acquisition. Therefore, both soil pH and the C:N ratio resulted in an opposite outcome for heavy metal acquisition (Juřička et al, 2022), which might be explained by the extremely high heavy metal concentrations in the soil, where they were taken up under transpiration mass ow in trees at polluted industrial sites.…”

“…The mobility of heavy metals is strongly related to soil pH; a higher soil pH near neutral indicates a decreased mobility of heavy metals (Rademacher, 2003;Sherene, 2010;Bardule et al, 2020). Tree species-speci c litter qualities can have a signi cant in uence on forest oor chemical composition and soil genesis (De Schrijver et al, 2011;Juřička et al, 2022). Previous studies on hybrid aspen plantations have reported a decreased soil pH 15 years after planting on former agricultural soils (Lutter et al, 2016b) and post-mining areas (Lutter et al, 2017a).…”

“…Another important driver of heavy metal accumulation in soil and uptake by trees is related to the quality of soil organic matter (Kwiatkowska-Malina, 2018;Wang et al, 2019). Juřička et al (2022) found that the mobility of Cd and Cu was driven by the soil C:N ratio (a proxy for the soil organic matter decomposition rate). Mandre (2014) compared the uptake capability of hybrid aspen trees' aboveground compartments (leaf, shoot, stem, bark) and found remarkable differences in the accumulation and partitioning of heavy metals.…”

Fast-growing Populus spp. are well-acknowledged to restore contaminated soils from heavy metals in industrial areas. Thus far, there is no knowledge about the phytoremediation capacity of Populusspp. plantations in hemiboreal conditions to restore industrially polluted areas. The objective of this study was to assess the soil contamination rate of heavy metals (As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Zn) and their uptake by mature hybrid aspen (Populus tremula × Populus tremuloides Michx.) in plantations in different industrial pollution areas (e.g. cement factory, thermal power plants, oil shale mining). For the reference, industrially polluted plantations were compared with the low pollution area hybrid aspen plantation on former agricultural soil, which was in uenced by fertilisation and liming before afforestation. Twenty-one years after afforestation, soil samples were collected from the 0-10 cm topsoil layer. Aboveground biomass sampling was performed for bark and stem wood by ingrowth cores to separate wood formed during early (1-10 years) and late (11-21 years) stand development. Two decades after the afforestation of industrially polluted areas, the heavy metal concentrations in the soil were higher than the reference plantation and the standard reference for unpolluted soils in most cases.The highest concentrations of heavy metals in woody biomass were in the oil shale quarry spoil; because of poor growth, the accumulated pools in aboveground biomass were low. Cd differed from other metals and accumulated less in wood and more in bark. The concentration of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni and Zn) was higher in the rst decade of stand formation (1-10 years) than in the last 10 years (11-21 years). High pools of heavy metals were accumulated in aboveground biomass in the reference plantation, indicating the considerable removal of heavy metal residues from the previous fertilisation and liming source with harvest. Two decades of afforestation with hybrid aspen is too short for complete ecosystem restoration from heavy metals in industrially polluted areas, but high concentrations in woody biomass indicate a high phytoremediation capacity.

“…There is little information about factors such as the carbon-to-nitrogen ratio (C:N) in relation to metal mobility in forest soils. In one study, the C:N ratio had a signi cant impact on both Cd and Cu content, regardless of forest type, and is therefore a primary factor affecting Cd and Cu mobility in the soil (Juřička et al, 2022). This highlights the importance of speci c site conditions.…”

Fast-growing Populus spp. are well-acknowledged to restore contaminated soils from heavy metals in industrial areas. Thus far, there is no knowledge about the phytoremediation capacity of Populusspp. plantations in hemiboreal conditions to restore industrially polluted areas. The objective of this study was to assess the soil contamination rate of heavy metals (As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Zn) and their uptake by trees in mature hybrid aspen (Populus tremula× Populus tremuloides Michx.) plantations at different industrial pollution (e.g. cement factory, thermal power plants, oil shale mining) levels and soil restoration methods. In total, 65 soil samples from the 0–10 cm topsoil layer, 39 wood samples and 39 bark samples were collected. Ingrowth cores were cut to separate wood developed to early and late ages. Soil pollution with heavy metals was determined in all studied plantations. Our study showed that tree growth was affected by soil pH and C:N ratio rather than the heavy metal concentration in the soil. Cd differs from other metals and accumulates less in wood and more in bark. A direct influence of wood age was confirmed; heavy metal (Cd, Cr, Cu, Fe, Mn, Ni and Zn) content in the old wood (formed 11–21 years ago) was higher than in young wood (formed during the last 10 years). The highest amounts of metals would be removed with felling on former agricultural soils with higher biomass, although wood on poorly growing stands in quarry spoil contained higher metal concentrations.
