This study investigated the level of Cu, Zn,
Fe, Pb, V, Ni and Cd in sediment samples of an oil-spillimpacted site in Ogoni land, Okenta Alode, Eleme local
government area, Rivers state, Nigeria. Soil sediments
were collected from six different stations, with two from
each station at surface (0 – 15 cm) and in-depth (15 – 30
cm) levels. One of the stations involves a bioremediated
site, which was used as the control for the study, while
the other station involves oil-spill-impacted sites.
Bioremediated soil, obtained at about 200 meter away
from the contaminated site was also collected making a
total of twelve (12) samples, with the coordinates of the
locations recorded with GPS device. Sample preparation
and analysis were carried out using American Society of
Testing Material (ASTM) D5708 (classic wet chemistry
method) using the appropriate NIST standards. The
filtrate which was containing the heavy metals in
solution was then analyzed using
