“…Results showed significant enrichment of Cr and Ni in studied agricultural lands, although with similar values as indicated by Doabi et al [13] for agricultural areas in Kermanshah province, Western Iran. When compared with other agricultural areas from arid/semiarid environments e.g., [3,[48][49][50][51][52], our studied soils showed similar values to studies from other regions. In general, the contamination level of our samples was low, and higher contents seem to be related to inputs of fertilizers and pesticides [42,53], with a low influence from industrial or urban sources.…”

Potentially toxic elements (PTE) are considered to be dangerous threats, both for human health and the environment. Here, the contamination level, sources, and ecological risks posed by PTE were investigated in 19 topsoils from agricultural lands in the Bandar Abbas County on the southern coast of Iran. The soil fraction <63 μm was used for the analysis of the pseudototal contents of PTE (arsenic, cadmium, cobalt, chromium, copper, lead, manganese, molybdenum, nickel, vanadium, and zinc). The results were analyzed using principal component analysis (PCA) and Pearson’s correlations, different pollution indices [enrichment factor (EF), contamination factor (Cf), and modified degree of contamination (mCd), and the potential ecological risk index (PERI). The results of the pollution indices showed that the contamination levels of the studied agricultural soils are low to moderate, while the average PERI values indicate that the ecological risks of PTE range from low to high in the soils of the studied area. Correlations and PCA analyses suggest that studied elements have three possible origins: geogenic (chromium, cobalt, copper, manganese, vanadium, and zinc), anthropogenic (cadmium, nickel, phosphorus and lead) and atmospheric (arsenic) sources. These findings are helpful for the long-term assessment of PTE in the Bandar Abbas County.

“…The values in this study is higher than 0.27 -1.47 and 32.30 -98.50 mg/kg reported in soils [9]. A study by [30] on heavy metal content of agricultural soils recorded lower levels of Cd in the soil ranging from 0.150 -0.880 mg/kg, hence, concentration above EU limits could reflects the influence of human activity. The concentrations of Cr, Cu, Mn, Ni and Pb were within the ranging from 104.30 -230.00, 58.30 -207.50, 51.67 -97.50, 39.30 -99.50 and 60.00 -143.30 mg/kg recorded for Cr, Cu, Mn, Ni and Pb, respectively in irrigated soils [9].…”

This research work studies the impacts of irrigation and other agricultural practices on the soil along the bank of Tungan Kawo dam. The experimental analysis evaluates the soil physicochemical parameters and metal (Cd, Cu, Cr, Ni, Fe, Mn, Pb and Zn) concentrations using sequential extractions. The physicochemical parameters of the soils across the sites indicated values reported for less polluted soils. Also, analysis of total metals in the soils indicated lower concentration of all metals evaluated than recommended standard limits with exception of Cd. The results of sequential extraction of heavy metal in soil sample indicated that all metals were mainly associated with the residual, Fe-MnO and organic bound fractions. The residual fraction has the maximum concentration of metals especially in cool and dry season for Cr, Cu, Ni, Pb and Zn, whereas only a small fraction of all the heavy metal is extracted in water soluble, exchangeable and carbonate bound fractions. It indicates that the bioavailability index is low. Hence, mobility of the heavy metals by the surrounding plants grown on the soils is low.

“…The usefulness of soil which cannot be emphasized enough can be seen in human survival and existence, as well as plant and animal survival including micro-biological organisms hence the significance for a comprehensive study of the physical components and processes of soils has been greatly highlighted by Ukpong (2009). dumpsite, Mico et al (2006) utilized atomic absorption spectroscopy technique in investigation of Cd, cobalt, chromium, copper, press, manganese, nickel, lead and zinc in the rural soils of Segura River Valley in Spain. Al-Weher (2008) examined dimensions of Cd, copper and zinc in three types of fish utilizing atomic absorption spectroscopy strategy while Wieczorek et al (2005) utilized the equivalent.…”

This study evaluated the physico-chemical properties of the soil and water in Elebele Community in Ogbia Local Government Area of Bayelsa State, Nigeria. Standard sampling and analytical methods were employed. The predominant soils of the region are mainly sandy-loam and clayey-loamy. The soil physico-chemical properties were in good status as they were not toxic. Soil particle size distribution (sand silt and clay) was observed as follows: sand content ranged between 50.6%-86.2% with a mean of 64.5% at the surface soil while the subsurface soil ranged between 35%-80.2% with a mean of 60.2%. Silt on the other hand ranged between 7.8%-36% and a mean of 25.1% at the surface and ranged between 12.8-49.6% and mean of 25.4% at the subsurface while clay ranged between 3.4%-16% and mean of 9.4% at the surface and also ranged between 7%-16% and mean value of the soil. However, the soil physical properties were relativity good for sustainability. Also, the metals studied were detected in all the sites. Generally the concentrations of the metals were highest at the top soils. This is expected since the top soil is the point of contact. The metal levels in all the sites were significantly higher than the levels observed in the control sites. Sources of heavy metals in soils like inorganic fertilizers and pesticides need to be controlled.
