The aim of this paper was to examine community perspective to petroleum exploitation and pollution in Ogoni, Rivers State. To achieve this aim, the objective was to determine the extent to which the pollution of the environment has affected the people’s views of usefulness of the resources in their communities. The survey design method was employed. Purposive sampling technique was used to select 21 oil bearing communities from the four Local Government Areas (LGAs) of Ogoniland. The data were collected using interviews, focus group discussions, oral testimonies and questionnaires. Being qualitative; transcriptions, rewriting and coding were employed in data analysis, except for the questionnaires which adopted descriptive statistical methods. Results showed that majority of the people have not benefitted from the petroleum resources in their communities. It was revealed that pollution has changed the people’s views of the usefulness of petroleum resources, as they clearly see the resources in their communities as a curse. However, many communities believed that there was no sincerity on the part of their leaders, as the dividends claimed to be given by the multinational oil companies (MNOCs) for the welfare and benefit of the people were not visible. It is recommended that in order to change the perception of the people toward petroleum exploitation, the MNOCs should massively develop the host communities with basic social amenities and deal directly with the land owners whose portions of land are directly affected and not through the chiefs or the Community Based Organisations (CBOs).

“…The potentials of similar vegetative components of plant have previously been reported by (Chen andLee,1997, Akonye andOnwudiwe, 2004). As a means of remediating soils polluted with petroleum derivatives or crude oil, soil amendments such as sawdust, peat, waste cotton and organic manures are added to soil (Tanee and Akonye, 2009). A soil amendment increases the ability of the soil matrix to supply biologically available water and nutrients to microorganisms that are capable of degrading the target compounds (Davis and Wilson, 2005).…”

Studies to investigate the growth performance of Cucumis sativus L. (variety Nandini 731 F1) in spent engine oil contaminated soil amended with compost of Urena lobata was investigated at the University of Port Harcourt Ecological Centre. The soil samples were polluted at four different concentrations, namely, 2%, 3%, 4% and5% with spent engine oil and amended with decomposed Urena lobata at the rate of 0.25kg per 3kg of soil alongside a control (0%). The growth parameters examined were: plant height, number of leaves, leaf area, stem girth and sprouting percentage. The study showed that the control treated with compost gave the highest values for plant height 23.73cm, number of leaves 16.33, leaf area 84.73cm 2 and stem girth 2,2cm while the 5% contamination recorded the lowest values for plant height 1.83cm, number of leaves 1.33, leaf area 2.19cm 2 and stem girth 0.1cm. The number of leaves significantly (P<0.05) decreased with increase in the concentrations of spent engine oil from 2% to 5%. The 0% + compost treatment recorded the highest number of leaves while the number of leaves for 0% alone was comparable to 2%, 3% treatments but higher than 5% treatments. The growth parameters decreased with increase in the levels of contamination, however the application of Urena lobata significantly increased the plant height, number of leaves, leaf area and stem girth at P< 0.05. This study suggests that compost of Urena lobata is an effective organic supplement for remediation of spent engine oil contaminated soil where Cucumis sativus is cultivated.

“…Maximum decrease (16.7%) was observed in 15 day old seedlings under 500 µM Zn stress (Figure 2). Earlier investigations showed that the heavy metals chromium, cadmium, manganese, lead and nickel [17] [23]- [25] reduces the leaf area; consequently total weight of the plant reduces. In this study, the reduced weight of the Zn-treated seedlings can be attributed to either a reduction in the number of cells or due to reduction in cell size.…”

“…Hundreds of experiments have been conducted on this legume to understand its morphology, physiology, as well as to understand the effect of different stresses on this legume. However, only a scanty number of experiments have been carried out to study the Zn phytoextracting ability of V. unguiculata [17]. In the present study, an experiment was performed to evaluate the Zn phytoextracting ability of V. unguiculata under in vitro condition.…”

Population explosion in the last decades together with global industrialization has caused heavymetal contamination of air, water and soil, resulting in diverse incurable effects on humans and on the stability of the ecosystem. Non-biodegradable heavy-metals can remain in the ecosystem and the threat associated with their bioaccumulation in food chains represents one of the major environmental and health problems of present day society. Several studies were carried out to understand the ecological effects of the heavy-metal Zn in soil-plant systems. Plants often have a zinc uptake that their systems cannot handle, due to the accumulation of zinc in soils. Of the several Zn toxicity symptoms, fatal are yield reduction, stunted growth, chlorosis, reduced chlorophyll synthesis and chloroplast degradation. Vigna unguiculata is an herbaceous, annual plant in the pea family Fabaceae. In the present study, an experiment was performed to evaluate the Zn phytoextracting ability of V. unguiculata under in vitro condition. We establish that V. unguiculata can uptake a considerable amount of the heavy-metal zinc and this phytoextraction property can be utilized in long run for the cleanup of zinc contaminated soil. To the best of our knowledge, this is the first report of Zn phytoextraction ability of V. unguiculata.
