Abstract:

This study examines the geospatial distribution of filling stations and assesses the relative distances between one station to another, closeness to the Residential houses/Public institutions, and the environmental health risks associated with the siting and operation of these filling stations in parts of the urban core area of Ibadan metropolis. eTrex Garmin 30x was used to determine the spatial coordinates (x, y) of all the filling stations and Quickbird satellite image with a resolution of 30m was used to show the position/location of the filling stations and as well as the existing features within the study area. Seventy (70) functioning filling stations were examined. However, two (2) hypotheses consisting of three (3) questions were formulated for this study. Questionnaires were administered to a sample of 250 respondents which was randomly selected from the study area. The data were analyzed using the non-parametric method of Chi-square. ArcGIS 10.4 (Arcmap 10.4) was used for image processing and field data analysis. The result shows that twenty-three (23) 32.86% filling stations comply with the International Standard of 1km distance to one another and the rest forty-seven (47) 67.14% did not comply. Also only five (5) 7.14% out of seventy (70) comply with 50m distance stipulated by Energy Regulation Board (ERB) to Residential houses/Public institutions such as churches, schools, public libraries, bus stops, markets, auditoriums, stadiums, hospitals around the filling stations while the remaining sixty-five (65) 92.86% does not comply within the study area. Also from the result, the three (3) hypotheses formulated for the study was null and rejected, as this shows that siting of filling station in the study area was not in conformity with the International Standard and as well as Energy Regulation Board and also had significant effects on the residential houses and public institutions and people’s health
