“…In the present study, we focus on contamination by the heavy metals zinc (Zn), copper (Cu), lead (Pb) and cadmium (Cd). Soil pollution by metals is most severe in industrial areas and in regions with mining and metal-processing activities [2][3][4][5]. Most attention though has been given to metal contamination of agricultural land [6,7], which has been reviewed by [8].…”

The restoration of forest ecosystems on metal-contaminated sites can be achieved whilst producing valuable plant biomass. Here, we investigated the metal accumulation and biomass production of young afforestations on contaminated plots by simulating brownfield site conditions. On 16 3-m2 plots, the 15 cm topsoil was experimentally contaminated with Zn/Cu/Pb/Cd = 2854/588/103/9.2 mg kg−1 using smelter filter dust, while 16 uncontaminated plots (Zn/Cu/Pb/Cd = 97/28/37/< 1) were used as controls. Both the calcareous (pH 7.4) and acidic (pH 4.2) subsoils remained uncontaminated. The afforestations consisted of groups of conifers, deciduous trees, and understorey plants. During the four years of cultivation, 2254/86/0.35/10 mg m−2 Zn/Cu/Pb/Cd were extracted from the contaminated soils and transferred to the aboveground parts of the plants (1279/72/0.06/5.5 mg m−2 in the controls). These extractions represented 3/2/3% of the soluble soil Zn/Cu/Cd fractions. The conifers showed 4–8 times lower root-to-shoot translocation of Cu and Zn than the deciduous trees. The contamination did not affect the biomass of the understorey plants and reduced that of the trees by 23% at most. Hence, we conclude that the afforestation of brown field sites with local tree species is an interesting option for their reclamation from an ecological as well as economic perspective.

“…The global industrial revolution has released the exceptional value of toxic elements (contaminants) in the environment. The majority of pollutant sources are characterized by rapid urban sprawl and increased growth in population (Dhaliwal et al, 2020;Shammi et al, 2021). This exponential growth of the world population has trained phenomenal rise in municipal solid wastes worldwide (Karak et al, 2012).…”

Solid waste has always been an integral part of human life, and the production of these substances is increasing with the growth of the human population. One of the most critical environmental problems of the present age is the release of pollutants from landfills into the soil, surface, and groundwater of the surrounding environment. Thus, the main objective of this study is to evaluate the extent of soil pollution and potential ecological and health risks related to the disposal of municipal solid waste (MSW) near a landfill site in Kazerun, Iran. Soil samples were collected from inside the landfill (ILA), agricultural land (AGL), and nursery land (NUL) and analyzed for six heavy metals (HMs), including As, Cd, Cr, Cu, Ni, and Zn. Results revealed that the HMs in ILA soils had moderate n to high pollution risk. As and Cd had the highest concentration in the study area, and all HMs were higher than the background value. Cluster analysis (CA) showed that studied metals might be characterized as two groups: group 1 (Ni, Cu, As, and Cd) related to anthropogenic activities in the study area. In contrast, group 2 (Cr and Zn), was associated with parent materials. The health risk assessment results showed that oral ingestion was the primary exposure path for elements, and children were more vulnerable to harmful health effects. Metals, namely Cu for adults and As, Cr, Cu, and Ni for children, pose maximum cancer risks. HQ and HI values were lower than the threshold limit, indicating no non-carcinogenic health risk to humans. Moreover, possible harmful impacts of HMs accumulation in nature and soil near human settlements call for appropriate planning for discharging toxic waste in these areas.

“…Soil contamination with potentially toxic metals (PTM) is one of the main environmental problems all over the world due to an increasing anthropogenic load on the environment. [ 1–4 ] Electroplating sludge (ES) is a solid waste of electroplating enterprises and one of the main sources of PTM release into the environment.…”

“…Aspects of migration of PTM in the system “industrial waste‒soil” have been studied in many publications. [ 2,3 ] The authors of papers on assessing quality of the environment [ 6–8 ] showed that the presence and high concentrations of copper and zinc ions in ES and their diverse mobility in the environment make these metals to be considered as sensitive indicators of industrial pollution. The level of soil contamination could be determined by the following indicators: enrichment factor, pollution load index, [ 2 ] geoaccumulation index, [ 3 ] contamination factor, and ecological risk index.…”

The relevance of the study is due to the fact the high concentration of copper and zinc ions in waste from electroplating industries and their different migration in the environment make these metals sensitive indicators of industrial pollution. The aim of this work is to study the vertical migration of copper and zinc ions from model sulfate copper‐zinc sludge into the horizons of four soil samples. Technogenic pollution with copper and zinc in the “sludge–soil” system is explained by the chemical composition of galvanic sludge, the properties of metals included in it, and the physicochemical properties of soils. An increase in the content of Cu2+ and Zn2+ with depth is recorded in all layers of the studied soils after pollution with maximum accumulation in the upper layer. The index of the pollution concentration of Zn2+ is 8–31 times higher than that of Cu2+. The fixation of Cu2+ and Zn2+ in the upper soil layer and low migration to the lower layers is facilitated by a high sum of exchangeable cations up to 12.8. The values of the factor of element contamination indicate a high risk of contamination of the upper horizons of the studied soils.
