The concentration of some selected heavy metals (Cd, Fe, Cu, Zn, and Pb) in water, soil and plant
(
Telifaria Occidentalis
) grown in two different farmlands located in Bwari, Abuja, Nigeria was investigated using an
Atomic Absorption Spectroscopy (AAS). The results obtained indicated the following mean concentration for the heavy
metals in water (mg/l): Farm A: Cd (0.005±0.0003), Cu (0.076±0.0005), Pb (0.745±0.0001), Fe (23.460±0.0009) and Zn
(1.415±0.0017); Farm B: Cd (0.008±0.0002), Cu (0.083±0.0003), Pb (0.608±0.0001), Fe (10.925±0.0005) and Zn
(1.193±0.0006). Soil (mg/kg): Farm A: Cd (0.040±0.0001), Cu (0.263±0.0003), Pb (0.134±0.0001), Fe (16.404±0.0199)
and Zn (22.207±0.0010); Farm B: Cd (0.042±0.0002), Cu (0.445±0.0002), Pb (0.131±0.0001), Fe (239.471±0.0050) and
Zn (25.385±0.0008). Plant (mg/kg): Farm A: Cd (0.031±0.0003), Cu (0.187±0.0005), Pb (0.00±0.0001), Fe
(9.400±0.0004) and Zn (0.732±0.0002); Farm B: Cd (0.030±0.0002), Cu (0.189±0.0002), Pb (0.00±0.0002), Fe
(8.901±0.0004) and Zn (1.169±0.0003). The concentration of iron metal analyzed in water, soil and plant samples from
the two different farmlands were high compared to other selected metals. The value of Cd, Pb and Fe obtained in water
sample from Farm A and B exceeded the WHO/FAO permissible limits.
