Remote Sensing Techniques in the Investigation of Polluted Soils at Illegal Dumpsites in Yenagoa Metropolis, Bayelsa State, Nigeria

Abstract

Remote Sensing Techniques in the evaluation of Polluted soils at illegal dumpsites in urban Soil environment and its effect on human being in Yenagoa metropolis, Bayelsa State compels us to investigate the presences of the following heavy metals, such as Fe, Mn, Cr, Cu, Zn, Ni, Cd, and Pb. The result reveals High-level of heavy metals accumulation at illegal dumpsites. Soil sample by leachate migration from the open dumpsite and all the illegal dumpsites found within the marketplace close to Epie Creek which serves as a significant source of household water and a tributary to River Nun. Our results also show that population increase in migration of human being from villages to the city in land use/land cover map built-up area contains 16.96 km2 with 4%, and bare land 20% in 1992 and 2020 land use/land cover built-up area contain 93.30 km2 with 23% and bare land is 35%. Therefore, the percentage from 1992 to 2020 in built-up area especially by 19% and bare land by 15% thereby water bodies and vegetation decreases. The area lacks environmental law for dumping disposals and the government needs to carry out landfill site suitability for solid waste disposal site using Remote sensing and GIS in other to reduce soil pollution by heavy metals in the area over time.
