“…In a similar study, Shaheen et al [3] showed high elemental concentrations in the topsoil and subsoil, which were generally lower than the concentrations obtained in this study. Also, the patterns of the elemental pollutions were in agreement with the study of de Borba et al [1], which shows distinct changes in the concentrations of toxic elements in soil profiles and depths around dumpsites in Brazil using the Xray fluorescence technique.…”

“…Previous studies had shown that the background elemental concentrations were determined from samples obtained in locations with low or no contaminants and served as the basis for the determining study samples pollutions [38][39]. In this study, the direct method of determining background concentrations involving geochemical analyses of the control samples was adopted instead of the commonly used statistical method [1][2][3][40][41]. The statistical data are mainly secondary data that could be misinterpreted.…”

“…Solid wastes are generated daily from some human actions and activities, and the environment is highly polluted when disposed of on the surface or buried in the subsurface of the Earth. These solid wastes could be waste products from domestic, industrial, and commercial activities, and over time, they have become an increasing problem with human civilization [1][2].

The concentrations of inorganic elements in soils of Saje, Ita-Oshin, Premier, and Oke-Diya dumpsites were determined using an X-Ray Fluorescence spectrometer to assess the soil quality through chronological changes with depths. A soil core sampler collects 56 samples at 20, 40, 60, and 80 cm depths. Saje showed high mean concentrations of Ca, K, Fe, Rb, and Ti at all depths, while Oke-Diya revealed high mean concentrations of Ca, K, Fe, Rb, Ti, Mn, Zn, V, Cr, and Ni at all depths. These concentrations were in a closed range suggesting a build-up of elements in the soil profiles. Oke-Diya had the highest pollution index, followed by Saje, and the contaminations were from anthropogenic and geologic sources. The mean concentrations of Fe, Zn, Ni, Mn, Ti, K, and Ca were high at all depths in Ita-Oshin, and in Premier, the mean concentrations of K and Fe were high at all depths. Premier had the lowest pollution index. Ita-Oshin and Premier enrichment factors showed geologic sources. Saje and Oke-Diya revealed unacceptable non-carcinogenic risks for adults and children, and Ita-Oshin and Premier recorded acceptable limits. Saje and Oke-Diya samples had high carcinogenic risks for adults due to Cr, Pb, and As. Elements Cr and As in Ita-Oshin, and Pb in Premier evinced unacceptable carcinogenic risks for adults. Saje, Oke-Diya, and Premier indicated unacceptable carcinogenic risks for children due to Cr. The study showed toxins build-up in the soil system, and the study areas are not suitable for growing crops and sinking water wells for agricultural and domestic uses.

“…Their results showed that the accumulation level of HM in soil was slightly higher than the standard level, which pointed out that it would be hazardous to humans and the vicinity of the environment. Borba et al (2020) examined the concentration of HMs in soil applied as land lls in Southern Brazil. Despite the collection depth, results showed variations in the concentration of cadmium and chromium.…”

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.
