9 PAGES (800 WORDS) Geology Project
ABSTRACT

This Research examines the heavy metal distribution of a dumpsite in Uvwie Local Government Area along Warri Port Express-Way of Delta State Nigeria. A total of eight (8) soil samples and (2)-plant sample were collected from the study area and also control site using a systematic sampling technique. Samples were taken to the lab and analyzed to determine the physicochemical parameters and heavy metal content. The dumpsite is contaminated with heavy metals such as iron (ranging from 82.18ppm – 19.74ppm), cadmium (0.391ppm 0.012ppm), and chromium (0.31ppm – 0.01ppm). Iron is the predominant metal in the vicinity with values ranging from 82.18ppm – 19.74ppm; the abundance of the six metals monitored is Fe, Ni, Cr, Pb, Cd, and Cu. Evidence of migration of contaminants from this site over 150m away. However, in the plant samples (paw-paw & bitter-leaf) obtained near the dumpsite and also at the control site shows that heavy metals such as nickel (
