Spatial Distribution of Energy Stations and Monitoring of Air Quality in Port Harcourt, Rivers State, Nigeria.

Abstract This study examines the geospatial locations of energy stations within Port-Harcourt Aba expressway to ascertain their locations if it conforms to standard practice. It also took into cognizance the in-situ monitoring of the various air pollutants within the vicinity of the energy stations. The study location is in Obio/Akpor and Port Harcourt city Local Government Area, Rivers State. The result of the proximity analysis reveals that the energy stations do not fall within the standard of 15metres specified by DPR (Department of Petroleum Resources). The various pollutants examined are PM 10, PM 2.5, carbon monoxide (Co), Nitrogen Dioxide (No2), ground level ozone (O3), and sulphur dioxide (S02). The result reveals that their concentrations values fall within the permissible limit as specified by NESREA except (C02) which is the primary pollutant was extremely highly than the permissible limit of 400 (ppm). This can be attributed to the influx of vehicles that buys fuel from the energy stations. The concentration of (C02) poses a serious health effect on the pump attendants due to their constant inhaling of the pollutants. The study concludes that energy stations should be cited at the approved DPR standard of (15metres) and actionable measures should be put in place to aid in the reduction of CO2 within the energy stations. Finally, the study recommends that there should be strict compliance to DPR standard in the siting of energy stations.
