“…The statistical analysis of the data revealed that the fertilizer treatments did not have a significant effect on the average levels of Ca and P in the wood. These results are consistent with previous studies [40,41] that have reported similar levels of K, Ca, P, and Mg in hybrid alder wood. Furthermore, the analysis showed that there were no significant differences in the levels of heavy metals such as Cr and Zn between the different treatments.…”

In this study, the focus was on evaluating the effects of the initial treatment of wood ash and sewage sludge on hybrid alder clones’ aboveground biomass and elemental content. To measure the element concentrations in the tree rings, laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) was utilized, which is a valuable tool for dendrochemistry research, albeit with some challenges in accurate quantification. One important aspect of the study was the development and comparison of different “in-house” matrix-matched standards for the precise quantification of element concentrations in tree rings. It was found that the commercially available reference materials, IAEA 413 (algae) and IAEA 392 (algae), were the best choices due to their homogeneity. The study also revealed that the use of sewage sludge and wood ash as soil improvers significantly benefited the increase in hybrid alder biomass. However, no significant increase in element content was found in the obtained wood mass, and for some elements, there was a decrease in concentration.

“…As concluded above, the heavy metal concentrations in all studied plantations were higher than the average concentration in agricultural soils. Compared to the results of Bertins et al (2020) (stem disc samples of six-year-old hybrid aspen trees obtained from agricultural land in the central part of Latvia), the concentrations of heavy metals Cu and Fe in our reference site (D) wood were higher. The reason may be that the wood samples collected in our study re ected the effects of pollution and mining; in addition, our trees were older, and this could also increase the content, as proposed by the wood age analysis.…”

“…Some previous studies (Pulford and Watson, 2003;Zárubová et al, 2015;Praspaliauskas et al, 2018) have reported that young trees have a higher metal concentration (all in actively growing tissues, such as shoots and young leaves) compared to mature trees. However, studies at a young development stage (6 years old) report no variation in heavy metal concentrations in tree annual rings (Bardule et al, 2020;Bertins et al, 2020).…”

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.

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.
