Spatial Distribution and Perceived Environmental Health Impacts of Petrol Filling Stations in Ede, Osun State, Nigeria
The environmental health risks associated with petrol filling stations (PFSs) requires maximum compliance with planning standards in siting them. However, people’s awareness of the effects of PFSs on health and environment is germane to achieving efficient urban environmental health. This study, therefore, examined the spatial distribution of PFSs and the people’s perception of the health and environmental implications of PFSs in Ede, a traditional city in Nigeria. Cross sectional survey design and simple random sampling technique were used for data collection. A structured questionnaire was used in collecting information from the residents. GPS was used in obtaining the coordinates of the PFSs while speedometer was used in determining the distance of the PFSs to each other and residential land use. Fifteen PFSs were identified and sampled in the entire township. The information was obtained from the managers of the PFSs through questionnaire. Also, a total of 150 pretested structured questionnaires were administered to randomly selected residents of adjoining neighbourhoods to the PFSs. Descriptive statistics (frequency and percentages) was used to obtain the residents’ perception of the effects of PFSs on the environment and human health. ARCGIS 10.2 and Nearest Neighbour Analysis were used to establish the spatial distribution of PFSs. The people’s perception of the PFSs effects was low. With the nearest neighbour index of 0.71, the PFSs were linearly clustered along the major roads that dissect the town. There was less compliance to planning standards by majority of the PFSs. Embarking on awareness programme among the residents and enforcement of planning standards in sitting PFSs and other land uses will go a long way in addressing the problems of low perception and non compliance with planning standards.
