“…Although the organic carbon contents of the area were high, both oil and grease make the soils on the spillage site unfit for crop farming. This coincides with the findings of Nnaji and Egwu (2020).…”

The study was conducted to determine the level of concentration of heavy metals and physicochemical properties of the soils of the study area. The levels of pH varied slightly between 5.30 (ETAK IDIM) and 5.44(OKPSON 1).The concentration of the available Phosphorus varied from 2.08ppm(OKPSON 1) to 2.81ppm (ATAI 1). The Total Hydrocarbon Content varied from 4034.12 mg/kg (ITAK IDIM UKPA) to 4904.71 mg/kg (NEW BARRACK). The textural class of the soils was generally sand. The silt particles had range from 0.56% (ETAK IDIM and ATAI 11) to 2.00% (ITAK IBANG), The clay minimum value (1.00%) was obtained from ATAI 1 and maximum value of 3.00% was obtained from ITAK IBANG, OKPSON 1 and ATAI 11. The sand particles ranged from 95% (ITAK IBANG) to 98% (ATAI 1). While the concentration of Ammonium ion varied from 14.65ppmN (OKPSON 1) to 32.50ppmN (NEW BARRACK). The concentration of heavy metals showed that Pb varied between 12.41mg/kg (ETO ESEK) and 23.24mg/kg (NEW BARRACK); Cu ranged from 5.10mg/kg (ETO ESEK) to 18.12mg/kg (OKPSON 1);Cr levels ranged from 15.17mg/kg (OKPSON 1) to 23.00mg/kg (ETO ESEK); Ni varied from 1.00mg/kg (ETO ESEK) to 26.14mg/ kg (ATAI 1).

“…In Nigeria, the major source of energy is crude oil and the processes of crude oil production often results in environmental pollution. Nnaji and Egwu (2020) noted that oil spills are one of the most widespread forms of pollution on agricultural lands and water bodies in Nigeria. Oil spills impacts on the ecosystem can be severe.…”

“…Table 3 indicates that, the CEC values for the oil-bearings soils are lower than the value obtained in the control soil. This is similar to the results obtained by Nnaji and Egwu (2020). This could be accredited to the higher pH level of the control soil as the CEC of the soil is directly related to the pH (Domingues et al, 2020;Martinsen et al, 2015).…”

“…The pH of the oil-bearing soils varied from5.76 to 6.25 with average value of 5.99±0.22. The range is below 5.65 -6.92 reported in oil-impacted soils by Nnaji and Egwu (2020). The pH of the oil-bearing soils was more acidic and lower than the pH of the control soil (Table 3).…”

The physicochemical properties, total metal, metal fractions, and related human health problems of metals in oil-bearing soils of Akwa Ibom State were appraised using standard procedures. The study aimed at assessing the effects of crude oil and related activities on the properties of soil including metals (Cd, Cr, Ni, Pb and V), their fractions and associated health problems. Results showed that, levels of parameters were higher in the soils examined than in the control. The entire metals examined, apart from Cd, were within their acceptable limits however; higher than the limits for agricultural soils. Cd and Cr existed mainly in the readily available fraction, while Ni, Pb, and V occurred mainly in the reducible fraction in the studied soils. Conversely, these metals, except Cd, occurred principally in the inert fraction in the control. V/Ni ratio confirmed the soils as oil-forming continents and of organic matter origin. The natural factor, crude oil, and oil-related activities were major sources of soil contaminants. Anthropogenic proportions of metals were more in the soils investigated than in the background soil. The locations were contaminated with metals. Daily intake rates of metals were within their recommended doses except for Pb. The pollution status of the oil-bearing soils and the related human health risks have been revealed.

“…Some studies have been carried out in the Nigerian Southern to assess micronutrients levels in the soil and the effect of oil spillage on the micronutrients [17][18][19][20]. The physicochemical properties of soils including agricultural soils within the Nigeria Southern have been investigated [21][22][23][24][25][26].…”

We investigated the influence of soil properties on the availability or otherwise of micronutrients in agricultural soils impacted by inorganic and organic manures in the South-South Area of Nigeria. The levels of pH, organic matter (OM), cation exchange capacity (CEC), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in the understudy soil were examined. The measured pH, OM, CEC, Cu, Fe, Mn and Zn levels revealed: 6.04±0.49, 17.68±4.78 %, 7.97±0.81 Cmolkg-1, 5.27±0.82 mgkg-1, 232.49±16.01 mgkg-1, 109.30±9.85 mgkg-1, and 8.40±1.15 mgkg-1, for pH, OM, CEC, Cu, Fe, Mn, and Zn, respectively. The values were within the acceptable limits set by national and international standards. The study revealed variable relationships between the soil properties and micronutrients in the studied soils at p < 0.05. Soil pH exhibited a strong negative association with all the micronutrients except Zn. However, a strong positive correlation (p< 0.10) was recorded between pH and Zn. OM showed a significant positive correlation (p< 0.10) with Fe, a weak positive correlation with Zn, and a non-significant negative correlation (p< 0.10) with Cu and Mn at p < 0.10. CEC exhibited a fair positive association with Fe and Zn, and a non-significant negative correlation (p< 0.10) with Cu and Mn. The principal component analysis (PCA) identified a combination of anthropogenic and natural impact and the impact of agrochemicals applied as the major factors influencing the properties determined in the studied soils. The study concluded that soil properties have a strong influence on the availability or otherwise of micronutrients in the soil.
