Abstract
This is a study of heavy metal loading of sediment samples around a Gold-mining environment. It is aimed at examining the impacts of the mining operations on the receiving stream sediments in the mining area. Stream sediment samples were collected the gold mining villages in Atakumosa-west Local Government area of Osun State from March 2015 - February 2016. Control samples were collected from Tonkere village in Ife Central Local Government area of the state. A nuclear analytical technique (Particle induced x-ray emission) was used to determine the concentrations of heavy metals in the samples. Sediment samples in the mining area were shown to be loaded with high concentrations of toxic metals mostly in the dry season. Mean concentration values were reportedly higher than World Health Organisation’s (WHO) safe limit in sediment samples. Factor analysis of the data obtained revealed two (2) factors contributing different percentages in the three different locations of each of the mining villages influencing the occurrence of studied heavy metals. Results of similar analysis on control samples showed lower concentrations.
