Spatial Assessment of Air Quality and Meteorological Parameters of the Surrounding Area of Active Dumpsite in Port Harcourt Metropolis, Rivers State, Nigeria

The study analysed the distribution patterns of active dumpsites in Port Harcourt Metropolis, Rivers state, Nigeria. The study made use of locational data obtained through the use of Global Positioning System (GPS) and the data were subjected to analysis in ArcGIS environment. Nearest neighbour analysis was used to determine the significant distribution pattern. Findings showed that twenty-three active dumpsites were found in the entire Port Harcourt Metropolis and the distribution pattern of these dumpsites were significantly dispersed (Z=4225.54; p=0.0000). It is concluded that active dumpsites in Port Harcourt Metropolis are scattered all over and it is recommended that proper guidelines must be followed before an area can be sited to become a dumpsite. Also, there should be consideration of the environmental attributes so that the proportion of the effect can be minimized, while periodic monitoring of established dumpsites is essential to reduce the illegal siting of dumpsites.
