“…Edebiri and Nwanokwale [10] reported that metals present in spent oil are not necessarily the same as those present in the unused lubricants; Whisman et al (1974) observed that most heavy metals like V, Pb, Al, Ni, and Fe that are below detection in unused lubricants oil gave high concentration values in used oil. This is similar to the findings of Osawaru et al [26].…”

“…The reliance on fossil fuel to meet our energy need continue to exacerbate among other issues oil pollution due to spillage, threat to environmental integrity, and biodiversity loss [18,20,21,25,26]. Oil spills at auto mechanic workshops, electric power-generating plants, and small-and large-scale industries continued to receive insufficient research attention despite the potential for accumulation and negative effects on sustainable development.…”

Background: The present work assesses the concentration of some heavy metal, plant species composition, and microbial diversity of spent crude oil-polluted soil from electric generator plant house, auto mechanic workshop, bakery, and auto spare part shops in four local governments areas (Egor, Ikpoba-Okha, Oredo, and Ovia North) in Edo State, Southern Nigeria. Results: Hazard quotient (HQ) of heavy metals varied in all the spent crude oil-polluted soil evaluated in the study. The HQ of heavy metals from auto mechanic workshop had the highest values for Cr (2.19), Mn (0.0965), Zn (4.1108), Fe (9.32015), and Cd (0.0155). The most frequent bacterial and fungal species found in all 16 sites were Bacillus subtilis (93.75%) and Aspergillus niger (100.0%) respectively. Auto spare part shops in Oredo had a bacterial count of 1.0 × 10 5 CFU/g while the bacteria count around power generator plants in Egor had a bacteria count of 1.71 × 10 5 CFU/g. Some of the plant species identified around all the sites include Acanthospermum hispidum, Alternanthera repens, Axonopus compressus, Cyperus esculentus, Eleusine indica, Paspalum scrobiculatum, and Tridax procumbens. Conclusion: Spent crude oil pollution of the soil led to high amounts of heavy metal in the soil. However, the presence of higher plants and variable diversity and richness of microorganisms found in the soil are likely contributing to the remediation of the polluted soil.

“…The studies showed extreme levels of these parameters are evidence of their effect on plant growth [60]. Ogboghodo et al [62]; Osawaru et al [63,64] reported that crude oil affects the chemical characteristics of the soil leading to an increase in organic matter, and a decrease in available P. The authors further reported that the high levels of pollution caused by crude oil impeded the growth of maize. Table 1.…”

The rate of environmental degradation is an increasing trend globally and most especially in many developing nations where it has food production implications. This deterioration in environmental quality is mostly attributed to population growth, urbanization, industrialization, and unsustainable agricultural practices. The Niger Delta region of Nigeria is the oil and gas province of Nigeria. The activities of illegal crude oil refiners, theft, vandalism, etc. are common within the region, thereby leading to the degradation of major biophysical environmental matrices and conditions. Plant and fish-based diets are the major food sources for humans within the Niger Delta region. This review focuses on the implications of artisanal crude oil refining (ACOR) on sustainable food production in the Niger Delta region of Nigeria. The review found that the activities of artisanal crude oil refiners are harming the vegetation cover, altering the physicochemical and microbial composition of the soil, and releasing hydrocarbons into the environment, which are absorbed by vegetation leading to an increase in human and biodiversity contamination from ACOR as well as loss of arable farmlands, uncontrolled bush burning, and increased cases of soil erosion. Therefore, ACOR activities are having negative effects on food security, which is characterized by food availability, accessibility, stability, and utilization. Hence, there is a need to curtail the activities of ACOR through the issuance of operational liens followed by stricter regulations and monitoring of harmful emissions released during the processes.

“…Okra is a vegetable originally thought to have its origin from South East Asia, however, it is now widely cultivated in tropical and subtropical regions [10]. In West Africa, the wide varieties of okra cultivars are of two morphologically distinct species, the common okra, (Abelmoschus esculentus) and West African okra (Abelmoschus caillei) [11]. Okra is known as 'ilasa' in south-west Nigeria, In Igbo-Ora, Oyo state, south-west Nigeria, the speci c variety of okra it is called "ilasa kekere" and has been identi ed as A. esculentus [12].…”

Background Okra is a multipurpose plant which can be consumed freshly or dried. Okra contains iron, β-carotene and other phenolic compounds with important biological properties like flavonol and isoflavonoid derivatives which may possess anti-inflammatory properties. The objective of this study was to determine the effect of okra leaf on some iron regulatory proteins and its anti-inflammatory properties. Methodology: Fifty (50) rats were grouped into 10 groups with 5 rats per group and each group were fed with a pre-formulated diet of Abelmoschus esculentus leaf or the standard phytoestrogen diadzein. Hepcidin, ferroportin, ferritin, IL-6, IL-2 and MIP 1β were analysed using sandwich ELISA kits from Elabscience Biotechnology, Wuhan, China. Full blood count was analysed using Sysmex haemotology autoanlyser. Serum iron was also analysed spectrophotometrically. Results The results showed that, in male rats, 40% okra leaf-fed group had a significantly higher RBC count (p = 0.0419), haemoglobin concentration (HB) (p = 0.0054), haeamtocrit (HCT) (p = 0.012) and mean cell haemoglobin (MCH) (p = 0.0064) when compared to control rats. Serum iron, total iron binding capacity (TIBC), transferrin saturation, ferroportin, ferritin were all significantly higher (p < 0.05) in the experimental groups when compared to the controls. However, in female rats fed with 40% okra leaf, there was significantly lower hepcidin concentration (p < 0.001) in control group when compared to 10% Okra leaf fed group. Furthermore, the 10% okra leaf-fed group also had a significantly higher hepicidin concentration when compared to the 40% okra leaf-fed groups. IL-6 levels were significantly lower (p < 0.01) in female rats fed with 40% okra leaf when compared to the 10% okra leaf-fed group. Macrophage inflammatory protein 1 beta (MIP-1β) in male rats showed that the groups fed with 10%, 20% and 40% okra leaf (p < 0.001) had significantly higher levels when compared to control and diadzein administered group. Conclusion Our data indicated feed formulated from Abelmoschus esculentus leaf is a rich source of non-haem iron. Abelmoschus esculentus leaf also significantly imparts iron metabolism through its action on ferroportin and hepcidin. Also this study indicates that continuous consumption of Abelmoschus esculentus leaf may help act as an anti-inflammatory agent.
