Assessment Of Heavy Metals In Soil And Edible Vegetables Grown Within The Vicinity Of Abandoned Peacock Paint Industry In Ikot Ekan, Etinan Local Government Area, Akwa Ibom State, Nigeria
ABSTRACT
This research work was
carried out to investigate the level of some heavy metals (Fe, Zn, Cu, Pb, Cd
and Cr) ions in soil and some edible vegetables grown within the vicinity of
abandoned Peacock Paint Industry in Ikot Ekan, Etinan Local Government Area,
Akwa Ibom State, Nigeria. Comparison of heavy metals in crops and soils
obtained showed that heavy metals in crops were higher than those recorded in
soil and was attributed to bioaccumulation and bio-magnification of these heavy
metals in crop tissues. Mean concentrations of Pb ions in pumpkin leaves (Telferia occidentalis) in sampling
position QI, QII, QIII, QIV and the control were (7.28±0.08, 6.84±1.18,
4.65±0.75, 3.85±0.67 and 1.84±0.91) mg/kg respectively. Mean concentrations of
Fe2+, Zn2+, Cu2+, Cd2+ and Cr3+
showed similar trends in all the edible vegetables analysed in the study area.
The concentrations of heavy metals in soil samples obtained within the site
were significantly higher than those obtained from the control sites. The
levels of heavy metals in both soil and crop samples collected from the site
were significantly high to cause environmental concern as their concentrations
exceeded the tolerable limits, mean concentrations of Pb2+, Fe2+
Cu2+, Zn2+, Cd2+ and Cr3+ of heavy
metals in the soil were Pb2+ (11.16±0.54 mg/kg), Fe2+(2120.40±2.11
mg/kg), Cu2+(89.74±7.52 mg/kg, Zn2+(23.74±1.55 mg/kg), Cd2+(2.66±0.52
mg/kg) and Cr3+(3.24±0.71 mg/kg). However, the observed values were
higher than FEPA/ WHO standards.
