【 摘 要 】

Fingernail samples of young school children and selected adults were collectedwith respect to sex and ages in Ilorin Kwara state. The aim of this study was to determine thelevel of heavy metals (Fe and Cu) and trace elements (Mg and K) in the fingernails of youngschool children and some selected adults using atomic absorption spectrophotometer techniquesfor metal analysis. Soil samples were collected from the automobile workshop of the adultsexamined. Sample collection and preparation were carried out using standard procedures. Theresult of the study showed presences of heavy metal in the fingernails of young school childrenand Adults in order of Fe >Cu (0.43-6.85 μg/g, Cu 0.01-0.08 μg/g) and for essential trace metalsMg > K (Mg 0.47-1.97 μg/g, K 0.25-1.32 μg/g) respectively From the result of the study, Feshow higher concentration while Cu shows the least level. Metal concentration is higher in youngschool children when compared with Adults, statistical analysis show that there was significantdifference between the concentrations of heavy metal in fingernails of young school childrenwhen compared with Adults. For soil samples analyzed at the automobile workshop, theconcentrations of heavy metals range between Fe (344.97μg/g); Zn (2.4442 μg/g); Pb(0.93667μg/g), Cr (0.535 μg/g) and Cu (0.5017μg/g) respectively.
