Since the discovery of oil in Nigeria, way back in 1950s, the country has invariably suffered some negative environmental consequences such as oil pollution resulting from gas flaring and oil extraction, loss of mangrove trees, which before now was a source of livelihood for the indigenous people and habitat for the area’s biodiversity. Oil production activities have caused contamination of marine life, and habitat, which in turn have had negative consequences on the health of humans, who consume the sea food. Inadequate attention had been paid by the successive Governments of Nigeria and the oil companies to these environmental problems over the years.
In this study, an assessment of the effects of oil and gas exploration and exploitation on the nearby communities in some of Chevron’s operational areas was carried out using the Ugborodo community as a case study. Furthermore, investigations were carried out on the toxicity effects of the Escravos crude oil on aquatic organisms like Tilapia and a terrestrial organism such as the Earthworms (Lumbricus terrestris,). The study established the effect and the impact of crude oil when exposed to such organisms mentioned above. The rate of death of barbus fingerlings of Tilapia and the Earthworm (Lumbricus Terrestris) at different concentrations of crude oil was determined and reported. The community survey undertaken by polling data shows the dwindling of the natural resources of the area due to oil exploration and the survey indicate the impacts on natural resources from pollution by crude oil and the consequences on the affected communities using the Ugborodo community in the Chevron’s Nigeria Limited Operational base as a case study. / Environmental Sciences / M.Sc.
