Geospatial Analysis and Modeling of Indoor Air Quality in Some Residential Areas in the Niger Delta, Nigeria

The proliferation of industrial activities globally has led to the increase in concentration hazardous pollutants atmosphere. We thus hypothesized that Port Harcourt, an industrialized city, and host a foremost refinery Africa, would have high indoor outdoor environments. took air samples with gas monitor (Aero qual series 500) from environments 40 residential areas. sampling sites were georeferenced Garmin GPS geospatially analyzed using ArcGIS. Predictive models used determine Sulphur dioxide (SO2), Nitrogen (NO2), Carbon monoxide (CO). Our results reveal SO2, NO2, CO concentrations high-density areas compared low-density regions. In most areas, is higher than FMEnv NAAQS permissible limits both dry wet seasons. Diobu, highly populated highest pollution level. For example, this location was >15 ppm during season. study revealed influx vehicular traffic, cooking stoves firewood, use fossil fuel generators, tobacco smoking are some factors gases recommend old vehicles should be banned; also firewood discouraged reduce pollution. There regular monitoring quality.
