The study considered level
of heavy metals in various sections of vegetables
harvested from Atikankan, Aba–Egbira and Moshood
road dumpsites in Ekiti State, Nigeria with a view
to monitoring the pollutional status of these
dumpsites. Amaranthus cruentus and
Talinum fruticosum were the two vegetables used.
Heavy metal concentrations varied among different
plants. The concentration of heavy metals analyzed
was found to range from Cd (Nd to 0.90µg/g), Pb
(0.10 to 0.40µg/g), Mn (0.10 to 1.00µg/g), Zn (0.70
to 3.60µg/g), Fe (0.20 to 2.00µg/g), Cr (0.20 to
1.30µg/g), Cu (0 .20 to 2.50µg/g), Ni (0.20 to
2.10µg/g) and Co (0.20 to 1.40µg/g) respectively in
all the dumpsites. Cd was not detected in the root
of Amaranthus creuntus and leaf of Talinum
fruticosum (Moshood road dumpsite). The extent
of metal contamination in plants samples was greater
in Atikankan than other dumpsites. However,
concentration of Cd exceeds the WHO/FAO
limits for human consumption in Talinum
fruticosum.
