Analysis of Some Heavy Metal Background Concentration at Dandagoro Quarters, Katsina, Katsina State, Nigeria

Abstract

Human activities lead to the accumulation of heavy metals in an environment which make environment to be polluted. The research area has become stepwise engage with various waste such as refused dump, animal waste, engine oil, kerosene, spilling of disel etc which can introduce the trace heavy metals. Heavy metals are environmental threat for soils, are also dependent by plant and life of living organism. As the risk of exposure to heavy metals increases for humans directly or indirectly. The study of Analysis of Background Concentration Some Heavy Metals in soil samples extracted from Dandagoro Quarters, Katsina, Katsina State, located at latitude 37˚91ᴵ74ᴵᴵ to 76ᴵᴵE and the longitude 13˚8ᴵ24ᴵᴵN was carried out. At intervals of 100 m, soil samples were collected from the study area, and each 100 m was divided into 10 m. (B1-B10). In order to determine the concentration of the five examined heavy metals (Cr, Cu, Cd, Pb and Co,), a flame atomic absorption spectrophotometer (FAAS) was used. The locations have an average heavy metal concentration of 0.240, 0.110, 0.093, 0.002 and 0.001(ppm) respectively. Differences were seen by comparing the mean concentration of the heavy metals in the target areas with world health organization (W.H.O) threshold limit, national and international related studies and it was reporeted that the samples were not contaminated with the heavy metals. But the metals were presence and there is no need for urgent intervention and remediation measures by the authority. It was recommended that, factories, gas station and manufacturing industries should not be located at or near the area in order to reduced human activities so as to make environment stable and free from pollutants.
