Investigation of Nitrogen Dioxide Indices and The Creation of a Unique Geographical Information System (GIS) Layer Map for Nitrogen Dioxide Pollution in Minna, Niger State

Abstract

Environmental pollution is a nuisance that we have to put up with from day to day. This project was designed and executed such that an appropriate town-grown synergy advocacy could be evolved. The principal objective of this study is to help prepare the framework for nitrogen dioxide pollution database for Minna. Stations of interest were identified, appropriately geo-referenced and marked in the conventional way. The sample points (households) were re-visited with the nitrogen dioxide meter whence information about the sources of nitrogen dioxide and the corresponding values of nitrogen dioxide were logged progressively from one point to the next. All the stations used for this survey (about 5350 households and commercial centres) indicate nitrogen dioxide levels greater than the internationally recommended safe threshold of 0.0002ppm. Nitrogen dioxide signatures over Maikunkele and Mobil neighbourhoods are quite high because a significant number of households and business locations own cars and use generator.
