“…For example, in zone II, the Cd content ranged from 0.05 to 0.29 mg/kg, and this value was higher than in another study (Wuana and Okieimen, 2011). For Pb, Cu, Zn, and Cd, the value was normal, referring to several references (Alfaro et al, 2015;Chernova and Bezuglova, 2019;Santos-Francés et al, 2017). Generally, the enrichment of Cd is due to metals containing in waste in the landfill.…”

“…The enrichment of heavy metals in the study area may derive from natural sources in the host rock. However, the rock underlying study area is volcanic rock, which has lower Cd content (Chernova and Bezuglova, 2019;Santos-Francés et al, 2017). The other possibility of the enrichment is leachate containing Cd generated by landfills, which may come from heavy metals waste.…”

One of the negative impacts of the landfill as solid waste disposal is soil contamination by heavy metals. This study assessed heavy metals impact, especially Pb, Cu, Zn, and Cd, in the soil in Piyungan landfill, Bantul, Yogyakarta, Indonesia. The assessment was conducted by analyzing 15 soil samples from 25 cm depth in the study area, which was divided into three-zone. The study results showed that generally, the highest content of metals was found in zone II, which is located near or directly situated in a landfill site. The pollution index (PI) calculated showed in order Cd>Cu>Pb>Zn. The result also indicates that Cd has the highest pollution index and even the highest risk compared to Pb, Cu, and Zn. The eco-risk index (RI) calculation showed that the value was 29 to 70 demonstrating a low class. The result also indicates that the accumulation of heavy metals investigated in this study was normal, and that the ecological risk was relatively low.

“…Therefore, mobile HM compounds were determined in the extract from ammonium acetate buffer (pH = 4.8) in the ratio of soil solution 1:10. Without data on the total content of HMs in the studied chernozems, which serve to determine both the total soil contamination and the degree of pollutant mobility [11,15,23]. The total content of Pb and Cd was deter-mined as follows: soil calcined in a muffle was treated with HNO 3 (1:1) and H 2 O 2 (concentrated), reagents from Vekton (St. Petersburg, Russia) and boiled.…”

“…Lead (Pb) and cadmium (Cd) in the biosphere are in a dispersed state, and also have a high degree of toxicity, which makes these HMs one of the most active pollutants in the noosphere and allows them to be classified as hazard class 1 [11,19]. The fact of the possibility of migration of the studied HMs into various shells of our planet and active transfer along trophic chains has been experimentally proven [16].…”

The creation of artificial forest belts is an effective method of land reclamation. Forest belts have a positive impact on prevention of erosion processes, formation of heat and moisture regimes, reduction of turbulent exchange in the surface air layer and reduction of carbon dioxide share in the atmosphere. An important feature of forest plantations is the prevention of soil contamination with heavy metals (HM). It occurs due to profile redistribution of HM and partial remediation of soils. The obtained data confirm this position. Reliable transformation of leached chernozems under the influence of different-age forest belts in comparison with arable soils on the territory of All-Russian Research Institute of Sugar Beet and Sugar named after A.L. Mazlumov was revealed. Forest vegetation type contributes to more sustainable ecosystems due to stabilization of humus content and its uniform distribution throughout the soil profile. Correlation analysis revealed a close relationship between content of humus, soil solution pH and the gross content, as well as the exchangeable compounds of HM. An increase in the concentration of HM in the upper layer of arable chernozem was revealed; it was caused by active emissions of exhaust gases from agricultural machinery and the application of mineral fertilizers. The design of forest belts in order to restore contaminated soils is planned in the territory of Sichuan Province (southwest China). This project needs additional research, which is planned to be carried out in the future.

“…Geo-accumulation index can be calculated using this formula: = Where, C n was the measured concentrations of heavy metals in the soil, and B n was the concentrations of background heavy metals in the soil. The background concentration can be used to determine the damage of toxic element in the environment (Chernova and Bezuglova, 2019). The local soil background concentrations for Pb and Hg were not available, therefore we used average crustal concentration from study conducted by Taylor (1964).…”

Lithogenic and anthropogenic activities can increase the concentration of heavy metals in the soil and degradation of environmental quality. Pangkajene dan kepulauan (Pangkep) regency is one of the areas in South Sulawesi Province which has severe environmental pressure. Twenty two surface soils of Pangkajene dan Kepulauan (Pangkep) regency, South Sulawesi, Indonesia were collected in order to determine the contamination status and potential ecological risks. The geo-accumulation index (I geo ) and potential ecological risk index (RI) were used to evaluate the contamination and risk level. The metal content in soils was determined using cold vapor atomic absorption spectrophotometer (CV-AAS) for Hg and fl ame atomic absorption spectrophotometer (F-AAS) for Pb. The results showed that the concentration of Hg and Pb ranged from 20.81-223.47 mg kg -1 and 25.98-108.68 mg kg -1 respectively. Pb concentration in studied soil was below the quality standard for soil, whereas the Hg concentration was exceeded the soil quality standard. Agriculture fi eld in Bungoro sub-district has the highest Hg concentration. The I geo value showed that the soil in Pangkajene was extremely enriched with Hg and moderately enriched by Pb. The ecological risk index showed comprehensively the watershed area was at extreme risk level in need of effective monitoring and pollution control, and Hg is the important risk factor of Pangkajene watershed area.
