HEAVY METALS IN AMARANTH GREEN LEAVES (Amaranth hybridus L.) AND WATER LEAVES (Talinum fruticosum) HARVESTED FROM FARMLANDS AROUND DANGOTE CEMENT PLANT IBESE OGUN STATE NIGERIA.

Agricultural Sciences

Concentration of amaranth green leaves (Fe, Cu, Cd, Cr, Pb) in amaranth green leaves (Amaranth hybridus L.) and water leaves (Talinum fruticosum) were examined. The concentration of these metals was determined using standard laboratory protocols using an Atomic Absorption Spectrophotometer. The result showed high level of heavy metal concentration in the order Fe (10.23 mg/kg) > Cu (4.65 mg/kg) > Cd (2.42 mg/kg) > Pb (0.08 mg/kg) > Cr (0.06 mg/kg) in amaranth green leaves (Amaranth hybridus L.) when compared with heavy metal concentration detected in the water leaves (Talinum fruticosum) sample from four different farms around dangote cement plants in ibese, Ogun State Nigeria in the order of Fe (7.52 mg/kg) > Cu (4.65 mg/kg) > Cd (1.53 mg/kg) Cr (0.03 mg/kg) > Pb (0.08 mg/kg). The concentration of heavy metals (Iron, Copper and cadmium) in green leaves (Amaranth hybridus L.) from four different farms around dangote cement plants in ibese, Ogun State Nigeria were higher than the concentration of heavy metals of water leaf (Talinum fruticosum). It was observed that the concentration of Iron, copper, cadmium in the amaranth green leaf (Amaranth hybridus L.) and water leaf (Talinum fruticosum) were above WHO/FAO(2011-2013) safe limits.
