Assessment of Heavy Metals Concentration in Soil, Plants and Grains in Nasarawa North

In this study, heavy metals concentration in soil, plants and grains were determined for Chromium, Lead, copper, Zinc and Nickel from some selected areas in Kokona and Nasarawa local government area of Nasarawa state, Nigeria. Twelve samples (soil, plants and grain) were collected were prepared. The x-ray fluorescence spectrometry analysis result revealed the mean concentration of Cr (0.075, 0.075 and 0.046 mg/kg), Pb (0.026, 0.026 and 0.052 mg/kg), Cu (0.199, 0.199 and 0.252 mg/kg), Zn (0.079, 0.079 and 0.252 mg/kg) and Ni (0.014, 0.014 and 0.032 mg/kg) in soil, plants and grain respectively. The values of heavy metal concentration in soil, plant and grain are found to be below the world average. Thus, the public are free from significant health risk due to consumption of heavy metals in plants and grains from Nasarawa West, Nigeria.
