Evaluation of heavy metals concentrations in soil and water samples around e-waste dumpsites in Olabisi Onabanjo university, Ago-iwoye, South-western Nigeria
Abstract:In
this paper, the health implications of electronic wastes (E-Wastes) on the inhabitants
of the University site at Ago-Iwoye, Ogun State South Western Nigeria were
reported. The
main goal of this study was to evaluate heavy metals concentrations in the soil
around e-wastes dumpsite in soil and water samples at Olabisi Onabanjo
University, Ago-Iwoye Ogun State. The heavy metal concentrations in soil and water
around the e-waste dumpsites were measured and compared with international
standard limits. The values recorded for soil and water were below the
recommended safety limit. This is an
indication that the soil and water of Olabisi
Onabanjo University can be used for drinking, agricultural purposes, and
construction of buildings without causing any health hazard. The results of this study revealed that the presence
of heavy metals in water was not significant and in the order of increased
magnitude Cd < As < Ni < Co < Zn < Pb < Cr < Cu. However,
care must be taken to face the challenges in the future for health safety.
